80mm x 80mm Thermal paper roll size is widely used in supermarkets, shopping malls, restaurants, banks, and many other industries. This size has been the most popular item among many paper roll sizes. We are sending around 15 containers of 80mm x 80mm thermal paper to overseas markets every month, and the demand is still keeping increasing. You may be curious about the 80mm x 80mm thermal paper GSM, length and weight, or you may wonder what these terms mean. In this article, we will explain it to you.

1. GSM

80x80mm Thermal roll gsm and length
GSM (Gram per Square Meter) or grammage, is one of the most important parameters in the paper industry. It basically indicates how many grams a square meter of paper weighs. You can calculate it simply by taking a square meter of paper and weighing it.

The standard gsm of thermal paper is 48gsm, 55gsm, 60gsm, 65gsm, etc.

Another parameter you cannot ignore is the thickness of the paper sheet. This measurement is given in microns where 1 micron = 1/1000 of a millimeter. This can be confusing as different sheets may weigh the same in GSM but have different thicknesses in microns. For example, a piece of 58gsm thermal paper and a piece of 60gsm may be the same thickness. You cannot think a higher GSM indicates a thicker paper; a lower GSM indicates a thinner paper. This is due to several factors during the manufacture of the paper, including the type of coating on the paper, the amount of virgin fibers used or the bulkiness of the raw material.

Common paper’s weights and their approximate thicknesses are:

  • 48gsm = 50-55mics
  • 55gsm = 58-62mics
  • 60gsm = 77-83mics
  • 65gsm = 85-93mics

For thermal paper, it is usually to be sold in GSM since it is easier to use this to distinguish the paper’s grades. However, if you doubt a paper’s grade, you might wish to collect samples first to check the quality.

2. Length

A thermal roll is actually a cylinder. The unrolled cylinder’s perimeter is actually the paper roll’s length. You can get the paper length in several ways:

  • Ask your suppliers. Your suppliers should know the length of the paper roll size.
  • Measure it by yourself. You can unroll the paper roll by yourself and measure it with a tape measure (yes, that could be a little complicated!).
  • Calculate it by yourself. It requires some math to calculate the paper length. Check out this link about how to calculate paper roll length or use the tool below:

For 80mm x 80mm paper rolls, the length will vary from 50m to 88m depending on the paper gsm.

3. Weight

80 x 80 thermal roll weight

From the above picture, we can see that a paper roll includes two parts: the paper and the core. The plastic core’s weight is around 0.007kg, it can be ignored since it is very light and not significant. We can calculate the weight of a paper roll by the formula:

For 80mm x 80mm 60gsm thermal paper, the width is 0.08m, the length is 58m, and the grammage is 0.060kg/m². With this formula, we can easily get a weight of about 0.285kg for an 80mm x 80mm thermal roll.


With the different paper gsm, you will get different paper lengths and weights for the same paper roll size. Below is the summary of the 80mm x 80mm thermal paper roll gsm, length, and weight:

80mm x 80mm48gsm54um88m0.340kg
80mm x 80mm55gsm60um80m0.355kg
80mm x 80mm60gsm83um56m0.295kg
80mm x 80mm65gsm93um50m0.285kg

Don’t only force on the unit price when you order the paper rolls, but also force on the paper’s gsm & length. Trust but verify is a prudent piece of advice we give you.
