Choosing the right thermal paper rolls might seem minor, but it’s a small decision that affects print quality, compatibility with your POS hardware, and long-term costs. This quick guide explains the core specs to check — and how to buy with confidence.
1. Check your device's core & roll diameter
The most common receipt roll size is 2 1/4" (57 mm) and often sold as 2 1/4" x 50–60'. But hardware varies. Look up your POS, terminal, or cash register manual and confirm two measurements:
- Roll width: How wide the paper is (e.g., 57 mm / 2 1/4").
- Core diameter: The internal cardboard core size (commonly 12 mm or 17 mm).
2. GSM (paper weight) — what it means
GSM (grams per square meter) affects thickness and feel. Typical thermal rolls for POS range from 48–70 GSM. Lower GSM rolls are thinner and cheaper, while higher GSM rolls feel sturdier and may produce cleaner print on some printers.
3. Thermal sensitivity & print longevity
Thermal rolls have a heat-sensitive coating. If you need receipts that resist fading for several years, consider thermal paper specially formulated for longer archival life — but note that typical thermal receipts are best for short-term records.
4. BPA / BPS and safety
Many businesses now prefer BPA-free or low-BPA alternatives. If your customers handle receipts often (restaurants, retail), choose products that state compliance with safety standards and provide a clear product datasheet.
5. Storage and handling
Store rolls in a cool, dry place away from direct sunlight. Heat, humidity, and oils can accelerate fading. For bulk inventory, keep rolls in their original packaging and rotate stock by FIFO (first in, first out).
6. Buying tips & cost considerations
- Buy sample packs to verify compatibility before ordering large quantities.
- Consider buying by the carton or pallet for lower per-roll cost if you use a lot of receipts.
- Factor in shipping and storage costs — sometimes slightly higher GSM with better print can reduce reprints and customer service issues.
7. Quick compatibility checklist
- Paper width matches device (e.g., 57 mm).
- Core diameter fits the spindle.
- GSM meets your preference for feel and durability.
- Paper is labeled BPA-free if required.

- What is the most common thermal roll size?
- 2 1/4" (57 mm) width is the most common for credit-card terminals and many receipt printers.
- Are thermal receipts waterproof?
- No — standard thermal paper is not waterproof. Exposure to water or strong friction can smear or fade print.
- How long do thermal receipts last?
- Typical thermal receipts may fade over months to years depending on storage. For long-term records, consider printing on standard paper or using digital receipts.
