3 ways to Measure the Thickness of Paper – Expert Guide!

There are many uses of paper, and from packaging to other tasks like measuring the thickness of paper, it can be an overwhelming project, and getting awarded it can be a crucial one. However, measuring the thickness of paper determines its strength, durability, and use of paper. 

But the important question that comes to mind is how can you measure the thickness of the paper?

A single layer of paper might be very thin and hard to measure overall, as a regular ruler will not be able to use it for this. 

The answer to this question is confusing, but we will guide you in better steps on how to do this. 

Measure the Thickness of the Paper with a Ruler

There is no hassle in measuring the length and breadth of the layer of paper using a ruler. But only we have to do to determine the thickness of a single sheet of paper is by stacking the pile of papers and making a bundle out of that pile. With the use of a ruler, it will be easy to measure the stack of 100 sheets of paper with relatively low effort. 

By simple arithmetic rules, the thickness of one paper can be determined. You can get the answer by dividing the height of the paper bundles by the total number of paper sheets used to make the bundle. For instance, if 100 sheets of paper are in one bundle and with the help of a ruler, the height of the bundle will be 10mm. Thus, the thickness of the single-layer will be 0.1 mm.

However, measuring the thickness of the paper is a bit easy, but it is not advisable by experts. The risk of inaccuracy in this method to a great extent, but it might be the easiest method.

Measure the Thickness of the Paper with the Help of a Vernier Caliper

A Vernier caliper can measure the paper thickness with a bit more accuracy than other methods. First of all, you should know what the caliper is. 

A vernier caliper is a device used in physics to measure the internal and external diameters or dimensions. With the use of this device, we can measure paper thickness in a good manner and wrong way. A caliper comes with two jaws to grip the paper, and the measurement can be calculated. 

Moreover, in the first step, fix the paper’s setting on either inch or mm. reset the device and bring it up to the standard measurements by rotating the caliper’s wheel on the caliper piece and taking it to 0. Please assume that the device is an electronic one and measure any random item like a spoon or a stone and reset it to back and comes to 0. Doing this will make sure that the caliper gives an accurate measurement. 

Now take the 100 sheets of paper and pile them up on top of each other. With paper, make necessary measurements and match the thickness of the papers to be measured. Rotation of jaws will make it easy to fit the ream inside. The stack of papers should not be too tight. It might crush the papers, and the chance of inaccurate measurement will increase. If the caliper used is an electronic one, then the measurement of the paper will be shown on the screen; thus, you will get the exact measurement of the paper. 

For instance, if the measurement of paper shown on the screen is 1 inch or 1 mm. divide the 1 inch or 1 mm by the number of papers in a pile. If there are 100 papers in a pile, the thickness of the single sheet of paper will come to around 1/100=0.01mm or 1 inch. 

Measure the Thickness of Paper with a Micrometer

The most commonly used method to measure paper thickness as an alternative is a micrometer. With this method, you can obtain a more accurate measurement than with the Vernier caliper, and anytime you are measuring any item, you will require more accuracy.

A micrometer is a type of caliper used to measure the micron measurements. This means that paper thickness measured with a micrometer will be more accurate than the alternative two methods. 

To measure the thickness of paper with a micrometer, move the dial on the micrometer for the adjustment of jaws. Thus shafts of the micrometer will move up and down accordingly. Checking any other item for thickness will give you an idea of accuracy. Then proceed with your process for the measurement of paper.

Pile up the 100 sheets of paper, set the micrometer, and observe the movement of the shaft and the opening of the jaws. Adjust the jaws and check the marks on the gauge. The shaft guage is a series of lines going from 0 to 25. You will get the first measurement by the adjustments on the micrometer jaws for the pile of papers. Observe the lines on the gauge with the opposite lines of the shaft to take the second measurement.

The lines will show the thickness of the paper, as these two measurements will help you get the thickness of the paper. Now add these two measurements, and you will get the accurate thickness of paper and divide this digit by the number of sheets used in the pile of papers. 

For instance, if there are 100 sheets of paper in a pile, and the total thickness you get is 0.106 inches, the measurement of thickness for one paper will be 0.106/100 equals 1.06 x 10 .3 inches per sheet. 


It is obvious from the above methods that the thickness of the paper can be measured with a variety of methods as all are accurate and practical. But the most common use to measure the thickness of the paper is by micrometer because this is the most accurate one. If you want to opt for the easiest method, measuring the paper thickness with a ruler is best. 

Therefore using the micrometer for the thickness of the paper is the better method to avoid the chances of inaccurate measurements.
