When shopping for 80mm thermal paper rolls, one of the most common questions is: How long is the roll? The answer isn’t fixed — it depends on the paper’s GSM (grams per square meter). In this article, we’ll explain how GSM affects roll length and help you choose the right product for your POS printer or receipt system.
What Is an 80mm x 80mm Thermal Paper Roll?
An 80mm x 80mm roll refers to the width and diameter of the paper roll. It is commonly used in receipt printers found in retail stores, restaurants, and hospitality businesses. However, the actual length of the paper (measured in meters or feet) depends on how thick the paper is — that’s where GSM comes in.
GSM vs. Roll Length
GSM stands for grams per square meter and measures the density or thickness of the paper. The lower the GSM, the thinner the paper — which means you can fit more length into a roll of the same diameter.
| GSM | Approximate Roll Length (80mm x 80mm) |
|---|---|
| 55 GSM | ~50 meters |
| 52 GSM | ~58 meters |
| 48 GSM | ~70 to 88 meters |
