Paper Thickness Tables

Caliper is expressed in thousandths or hundred thousandths of an inch. In the paper industry, paper thickness is also expressed in points (a single point is .001″). To convert decimal-inch values into points, divide the average caliper by .001. For example, a sheet of paper that is .0095″ thick has a caliper of 9.5 points.

Presenting The Paper Thickness Calculator You Have Been Waiting For!

Need a paper thickness calculator that will be with you through thick and thin? That’s our caliper table. 

All you need to use it is to know what kind of paper (in a standard size) you’re interested in purchasing, and its basis weight, and then you can use this table to find out the average caliper for everything from vellum to ledger. Trust us, you’re going to want to know the thickness of the paper you’re considering, because it affects a lot of aspects of printing, packaging, and publishing. Still have questions? We’ll try to answer them below. 

Paper Caliper Frequently Asked Questions

Confused about caliper considerations? Let’s thin out your uncertainty about paper and board thickness.

What is caliper in paper?

Caliper is a measure of the thickness of paper and paperboard. It is expressed in points, or “pts,” which are all one one-thousandth of an inch. That’s helpful to learn if you’ve just been ap-point-ed the person in your company who does the premium paper ordering. 

By the way, this unit of caliper, pts, is the one we use in North America, but for folks that use the metric system, fractions of a millimeter are the preferred way to quantify caliper.

How is paper caliper measured?

A device called a micrometer can be used to measure caliper in paper and paperboard. Considering that basically means, “small measure,” it makes sense that this tool helps you take the tiny measurements required for caliper with precision. The micrometer clamps around the paper or board to show you how thick it is on either an analog gauge or a digital screen. It is great at tiny measurements (that’s sort of the whole point!)

What affects caliper in paper? Hint: It’s not weight! 

The coating or finish on a paper has an impact on paper caliper. Rougher textures of paper tend to be thicker (higher caliper) than smooth finish papers, even if they weigh the same. It’s important not to make assumptions based on the weight of the paper. So, for example, coated papers tend to be heavier than uncoated papers, but not necessarily thicker. Basically, when it comes to caliper, it isn’t always worth the weight! 

Certain processes can have an effect on paper caliper, but do not affect its weight. For example, calendaring, where iron rollers smooth out the paper and enhance its printability, can reduce caliper but keeps weight the same. That’s just another example of how, while caliper and weight are both valuable to know, they are not the same.

Unfortunately, this means that if you know the caliper of a particular paper or paperboard, that doesn’t mean you can convert that number into basis weight or grammage. But just “weight” and we’ll explain below how to find those metrics if you need them.

Is caliper the same as bulk of paper? If not, what is the difference between bulk and caliper of paper?

We can see why you might think that bulk and caliper are the same; outside of the paper world, if something is thick it could often be described as bulky. That’s not the case here, though.

In fact, caliper can be used to calculate the bulk of paper, because bulk describes the ratio of thickness to weight. Here’s how that works. Take your caliper and divide it by your basis weight.

Why might you want to know paper bulk? Bulk affects how well the paper prints and also its runnability, so it’s definitely important to know when planning what kind of paper to choose for your project. Plus, now that you understand the difference between caliper and bulk, you have a fun fact to pull out at parties! At least, at the kind of parties we’d like to attend. 

What does paper caliper affect? Why do I need to know my paper’s caliper?

Caliper is an important measurement to know when determining what kind of paper or paperboard to order. The caliper of paper can affect how flexible it is and how well it works for various applications. There are a lot of measurements to consider when placing your order, and some of them are related to caliper, including bulk that we described above, which compares the thickness to the weight of the paper.

Another measurement that is impacted by caliper is Pages Per Inch (PPI). That makes sense, because fewer pages will fit into a one-inch tall stack if the pages are thicker versus how many fill fit if they are thinner. In fact, caliper is part of the formula for calculating PPI formula, 2 divided by caliper = PPI. Not super into math? No worries — we have a PPI calculator, too!

On a more concrete level, if you want to read the spec sheet of a paper or paperboard product, it can be organized by caliper. So, for example, if you wanted to order some Primalith FSC coated paper (great choice, by the way) you could check out what its brightness is for different calipers. This makes caliper a handy way to compare specs across the same paper and between different types of paper.

How do I use this paper thickness calculator table? Do I need to know math?

We’re happy to explain how to use our paper thickness calculator. This table serves as an average paper thickness calculator, based on standard types of paper and its basis weight. Here are the steps: 

  1. Select the type of paper you need to know about: Forms, Book, Cover, Vellum, Index, Offset, Tag, or Ledger. 
  2. Find the correct sub-type. For example, Cover includes the sub-types “Uncoated Standard” and “Coated Standard.”
  3. Find the Basis Weight in the column on the left-hand side. 
  4. Find the corresponding Average Caliper in the column on the right-hand side.

If you want to see the caliper expressed in points (pts) that does require a bit of math on your part, but we promise it’s simple (and you can always use your computer or phone’s calculator for this part; we won’t tell.) You just take that caliper number from the right column and divide it by .001. Tada! You’ve got the caliper in points. We’re always happy to point you in the right direction.

What else might I need to calculate about my paper or paperboard?

Good question! Caliper is just one of many measurements you might want to know about your paper or board. Other important metrics include basis weight, which tells you how heavy your paper is. This is different from caliper, because a heavier paper (with a higher basis weight) will not always be thicker (higher caliper). If you don’t know the basis weight, you can calculate it here.

Another important metric is grammage. Grammage tells you how many grams per square meter (GSM) are in a ream of the paper you want. Check out our handy grammage calculator to find that out. Why does that matter? Grammage can help you understand how dense your desired paper is, and that affects what the paper feels like. 

With all of these paper and paperboard metrics around, it can feel overwhelming if you’re new to the biz. The good news is that we have paper and price calculators (eight of them, plus two more tables!) to help you avoid doing math at all costs! At Case Paper, we jump at the chance to make your life easier, any way that we can. Now, if only we could get your ketchup to come out of the bottle; once we figure out how to do that with a calculator, we’ll let you know.

Can I just get an app to handle caliper and other paper math for me?

Good news for millennials (or anyone who prefers apps to websites): there’s an app for that! Case Paper’s Paper Pros App is available on the App Store and Google Play. It’s got the power to figure out sizes, weights, thickness, unit conversions, and more. If you’d rather figure out your paper and board measurements from the comfort of your own bed (no judgment), just get out your phone and download it today.

What if I don’t want to do any calculations whatsoever? 

There’s one last formula that can help you avoid math: It’s You + Case Paper Representatives! Our team is on hand to help. Your Case Paper representative will ask you about your project in great detail, and use those answers to help you find the right product and the right amount to order.

For example, calendaring, where iron rollers smooth out the paper and enhance its printability, can reduce caliper but keeps weight the same. That’s just another example of how, while caliper and weight are both valuable to know, they are not the same.

Unfortunately, this means that if you know the caliper of a particular paper or paperboard, that doesn’t mean you can convert that number into basis weight or grammage. But just “weight” and we’ll explain below how to find those metrics if you need them.

Is caliper the same as bulk of paper? If not, what is the difference between bulk and caliper of paper?

We can see why you might think that bulk and caliper are the same; outside of the paper world, if something is thick it could often be described as bulky. That’s not the case here, though.

In fact, caliper can be used to calculate the bulk of paper, because bulk describes the ratio of thickness to weight. Here’s how that works. Take your caliper and divide it by your basis weight.

Why might you want to know paper bulk? Bulk affects how well the paper prints and also its runnability, so it’s definitely important to know when planning what kind of paper to choose for your project. Plus, now that you understand the difference between caliper and bulk, you have a fun fact to pull out at parties! At least, at the kind of parties we’d like to attend. 

What does paper caliper affect? Why do I need to know my paper’s caliper?

Caliper is an important measurement to know when determining what kind of paper or paperboard to order. The caliper of paper can affect how flexible it is and how well it works for various applications. There are a lot of measurements to consider when placing your order, and some of them are related to caliper, including bulk that we described above, which compares the thickness to the weight of the paper.

Another measurement that is impacted by caliper is Pages Per Inch (PPI). That makes sense, because fewer pages will fit into a one-inch tall stack if the pages are thicker versus how many fill fit if they are thinner. In fact, caliper is part of the formula for calculating PPI formula, 2 divided by caliper = PPI. Not super into math? No worries — we have a PPI calculator, too!

On a more concrete level, if you want to read the spec sheet of a paper or paperboard product, it can be organized by caliper. So, for example, if you wanted to order some Primalith FSC coated paper (great choice, by the way) you could check out what its brightness is for different calipers. This makes caliper a handy way to compare specs across the same paper and between different types of paper.

How do I use this paper thickness calculator table? Do I need to know math?

We’re happy to explain how to use our paper thickness calculator. This table serves as an average paper thickness calculator, based on standard types of paper and its basis weight. Here are the steps: 

  1. Select the type of paper you need to know about: Forms, Book, Cover, Vellum, Index, Offset, Tag, or Ledger. 
  2. Find the correct sub-type. For example, Cover includes the sub-types “Uncoated Standard” and “Coated Standard.”
  3. Find the Basis Weight in the column on the left-hand side. 
  4. Find the corresponding Average Caliper in the column on the right-hand side.

If you want to see the caliper expressed in points (pts) that does require a bit of math on your part, but we promise it’s simple (and you can always use your computer or phone’s calculator for this part; we won’t tell.) You just take that caliper number from the right column and divide it by .001. Tada! You’ve got the caliper in points. We’re always happy to point you in the right direction.

What else might I need to calculate about my paper or paperboard?

Good question! Caliper is just one of many measurements you might want to know about your paper or board. Other important metrics include basis weight, which tells you how heavy your paper is. This is different from caliper, because a heavier paper (with a higher basis weight) will not always be thicker (higher caliper). If you don’t know the basis weight, you can calculate it here.

Another important metric is grammage. Grammage tells you how many grams per square meter (GSM) are in a ream of the paper you want. Check out our handy grammage calculator to find that out. Why does that matter? Grammage can help you understand how dense your desired paper is, and that affects what the paper feels like. 

With all of these paper and paperboard metrics around, it can feel overwhelming if you’re new to the biz. The good news is that we have paper and price calculators (eight of them, plus two more tables!) to help you avoid doing math at all costs! At Case Paper, we jump at the chance to make your life easier, any way that we can. Now, if only we could get your ketchup to come out of the bottle; once we figure out how to do that with a calculator, we’ll let you know.

Can I just get an app to handle caliper and other paper math for me?

Good news for millennials (or anyone who prefers apps to websites): there’s an app for that! Case Paper’s Paper Pros App is available on the App Store and Google Play. It’s got the power to figure out sizes, weights, thickness, unit conversions, and more. If you’d rather figure out your paper and board measurements from the comfort of your own bed (no judgment), just get out your phone and download it today.

What if I don’t want to do any calculations whatsoever? 

There’s one last formula that can help you avoid math: It’s You + Case Paper Representatives! Our team is on hand to help. Your Case Paper representative will ask you about your project in great detail, and use those answers to help you find the right product and the right amount to order. They will quote you a price and help you place your order. No math required! Contact us today to get this simple process started.

So, Case Paper made this paper thickness calculator? Who are they?

Let’s get acquainted! We are Case Paper, a family company that’s been in business for over eighty years. That’s right, we’ve had four score and, um, quite a while of helping people find the paper and board they need to get their work done. During that time, we’ve always committed to being “On the Case” for our customers. That might make us sound like detectives, but it actually means that we work hard to fulfill your paper and board needs. As you can see when looking at everything from this paper thickness calculator, to our other calculators, our app, and even our helpful representatives, we do everything we can to streamline the paper and board ordering process, because life is already complicated enough. Now, which streaming service should you subscribe to? Can’t help you there.

Since we are a B2B paper and board company, our customers are mainly in publishing, packaging, and printing. Besides all being super cool people (obviously), we all have in common that we care about the quality and the sustainability of our work. For this reason, we conduct all our operations like we think every day should be Earth Day, because we do! That means swapping out our old, more energy-intensive traditional light bulbs for LEDs in all of our facilities. Specific facilities are also trying out motion sensors for lights and even solar panels. Besides saving energy, another way we show our love for the environment is generating less waste. We’ve taken steps to reduce office and factory waste, and we are even cutting our sheeter waste by leaps and bounds. (Oh, did we forget to mention that in addition to our products, we also provide converting services? We do.) 

Another thing we do for the environment here at Case Paper is carrying a lot of high-end sustainable products. Those products have certifications to show that forests were respected when harvesting the materials to make them, or they are made from recycled materials like post-consumer waste (PCW). After all, tree-ting our planet with respect is something everyone should be able to get behind.

Presenting The Paper Thickness Calculator You Have Been Waiting For!

Need a paper thickness calculator that will be with you through thick and thin? That’s our caliper table. 

All you need to use it is to know what kind of paper (in a standard size) you’re interested in purchasing, and its basis weight, and then you can use this table to find out the average caliper for everything from vellum to ledger. Trust us, you’re going to want to know the thickness of the paper you’re considering, because it affects a lot of aspects of printing, packaging, and publishing. Still have questions? We’ll try to answer them below. 

Paper Caliper Frequently Asked Questions

Confused about caliper considerations? Let’s thin out your uncertainty about paper and board thickness.

What is caliper in paper?

Caliper is a measure of the thickness of paper and paperboard. It is expressed in points, or “pts,” which are all one one-thousandth of an inch. That’s helpful to learn if you’ve just been ap-point-ed the person in your company who does the premium paper ordering. 

By the way, this unit of caliper, pts, is the one we use in North America, but for folks that use the metric system, fractions of a millimeter are the preferred way to quantify caliper.

How is paper caliper measured?

A device called a micrometer can be used to measure caliper in paper and paperboard. Considering that basically means, “small measure,” it makes sense that this tool helps you take the tiny measurements required for caliper with precision. The micrometer clamps around the paper or board to show you how thick it is on either an analog gauge or a digital screen. It is great at tiny measurements (that’s sort of the whole point!)

What affects caliper in paper? Hint: It’s not weight! 

The coating or finish on a paper has an impact on paper caliper. Rougher textures of paper tend to be thicker (higher caliper) than smooth finish papers, even if they weigh the same. It’s important not to make assumptions based on the weight of the paper. So, for example, coated papers tend to be heavier than uncoated papers, but not necessarily thicker. Basically, when it comes to caliper, it isn’t always worth the weight! 

Certain processes can have an effect on paper caliper, but do not affect its weight. For example, calendaring, where iron rollers smooth out the paper and enhance its printability, can reduce caliper but keeps weight the same.

How do I use this paper thickness calculator table? Do I need to know math?

We’re happy to explain how to use our paper thickness calculator. This table serves as an average paper thickness calculator, based on standard types of paper and its basis weight. Here are the steps: 

  1. Select the type of paper you need to know about: Forms, Book, Cover, Vellum, Index, Offset, Tag, or Ledger. 
  2. Find the correct sub-type. For example, Cover includes the sub-types “Uncoated Standard” and “Coated Standard.”
  3. Find the Basis Weight in the column on the left-hand side. 
  4. Find the corresponding Average Caliper in the column on the right-hand side.

If you want to see the caliper expressed in points (pts) that does require a bit of math on your part, but we promise it’s simple (and you can always use your computer or phone’s calculator for this part; we won’t tell.) You just take that caliper number from the right column and divide it by .001. Tada! You’ve got the caliper in points. We’re always happy to point you in the right direction.

What else might I need to calculate about my paper or paperboard?

Good question! Caliper is just one of many measurements you might want to know about your paper or board. Other important metrics include basis weight, which tells you how heavy your paper is. This is different from caliper, because a heavier paper (with a higher basis weight) will not always be thicker (higher caliper). If you don’t know the basis weight, you can calculate it here.

Another important metric is grammage. Grammage tells you how many grams per square meter (GSM) are in a ream of the paper you want. Check out our handy grammage calculator to find that out. Why does that matter? Grammage can help you understand how dense your desired paper is, and that affects what the paper feels like. 

With all of these paper and paperboard metrics around, it can feel overwhelming if you’re new to the biz. The good news is that we have paper and price calculators (eight of them, plus two more tables!) to help you avoid doing math at all costs! At Case Paper, we jump at the chance to make your life easier, any way that we can. Now, if only we could get your ketchup to come out of the bottle; once we figure out how to do that with a calculator, we’ll let you know.

Can I just get an app to handle caliper and other paper math for me?

Good news for millennials (or anyone who prefers apps to websites): there’s an app for that! Case Paper’s Paper Pros App is available on the App Store and Google Play. It’s got the power to figure out sizes, weights, thickness, unit conversions, and more. If you’d rather figure out your paper and board measurements from the comfort of your own bed (no judgment), just get out your phone and download it today.

Presenting The Paper Thickness Calculator You Have Been Waiting For!

Need a paper thickness calculator that will be with you through thick and thin? That’s our caliper table. 

All you need to use it is to know what kind of paper (in a standard size) you’re interested in purchasing, and its basis weight, and then you can use this table to find out the average caliper for everything from vellum to ledger. Trust us, you’re going to want to know the thickness of the paper you’re considering, because it affects a lot of aspects of printing, packaging, and publishing. Still have questions? We’ll try to answer them below. 

Paper Caliper Frequently Asked Questions

Confused about caliper considerations? Let’s thin out your uncertainty about paper and board thickness.

What is caliper in paper?

Caliper is a measure of the thickness of paper and paperboard. It is expressed in points, or “pts,” which are all one one-thousandth of an inch. That’s helpful to learn if you’ve just been ap-point-ed the person in your company who does the premium paper ordering. 

By the way, this unit of caliper, pts, is the one we use in North America, but for folks that use the metric system, fractions of a millimeter are the preferred way to quantify caliper.

How is paper caliper measured?

A device called a micrometer can be used to measure caliper in paper and paperboard. Considering that basically means, “small measure,” it makes sense that this tool helps you take the tiny measurements required for caliper with precision. The micrometer clamps around the paper or board to show you how thick it is on either an analog gauge or a digital screen. It is great at tiny measurements (that’s sort of the whole point!)

What affects caliper in paper? Hint: It’s not weight! 

The coating or finish on a paper has an impact on paper caliper. Rougher textures of paper tend to be thicker (higher caliper) than smooth finish papers, even if they weigh the same. It’s important not to make assumptions based on the weight of the paper. So, for example, coated papers tend to be heavier than uncoated papers, but not necessarily thicker. Basically, when it comes to caliper, it isn’t always worth the weight! 

Certain processes can have an effect on paper caliper, but do not affect its weight. For example, calendaring, where iron rollers smooth out the paper and enhance its printability, can reduce caliper but keeps weight the same. That’s just another example of how, while caliper and weight are both valuable to know, they are not the same.

Unfortunately, this means that if you know the caliper of a particular paper or paperboard, that doesn’t mean you can convert that number into basis weight or grammage. But just “weight” and we’ll explain below how to find those metrics if you need them.

Is caliper the same as bulk of paper? If not, what is the difference between bulk and caliper of paper?

We can see why you might think that bulk and caliper are the same; outside of the paper world, if something is thick it could often be described as bulky. That’s not the case here, though.

In fact, caliper can be used to calculate the bulk of paper, because bulk describes the ratio of thickness to weight. Here’s how that works. Take your caliper and divide it by your basis weight.

Why might you want to know paper bulk? Bulk affects how well the paper prints and also its runnability, so it’s definitely important to know when planning what kind of paper to choose for your project. Plus, now that you understand the difference between caliper and bulk, you have a fun fact to pull out at parties! At least, at the kind of parties we’d like to attend. 

What does paper caliper affect? Why do I need to know my paper’s caliper?

Caliper is an important measurement to know when determining what kind of paper or paperboard to order. The caliper of paper can affect how flexible it is and how well it works for various applications. There are a lot of measurements to consider when placing your order, and some of them are related to caliper, including bulk that we described above, which compares the thickness to the weight of the paper.

Another measurement that is impacted by caliper is Pages Per Inch (PPI). That makes sense, because fewer pages will fit into a one-inch tall stack if the pages are thicker versus how many fill fit if they are thinner. In fact, caliper is part of the formula for calculating PPI formula, 2 divided by caliper = PPI. Not super into math? No worries — we have a PPI calculator, too!

On a more concrete level, if you want to read the spec sheet of a paper or paperboard product, it can be organized by caliper. So, for example, if you wanted to order some Primalith FSC coated paper (great choice, by the way) you could check out what its brightness is for different calipers. This makes caliper a handy way to compare specs across the same paper and between different types of paper.
