Thermal paper comes in a range of thicknesses from 50gsm to 80gsm. We are mainly using 60gsm thermal paper for our customers now since 60gsm thermal paper has an appropriate length and favorable price.

For example, for the most popular 80mm x 80mm thermal paper roll size, you can find the grades and price differences below:

Size Grade Thickness Length Price
80mm x 80mm  55gsm  60um  80m  $0.700
80mm x 80mm  60gsm  73um  63m  $0.610
80mm x 80mm 65gsm  80um  60m  $0.590

In general, if customers don’t have a specific requirement, we will use 60gsm thermal paper by default. You can read this article to know thermal paper gram/length/weight.
