Buying fax paper is more complicated than it looks — wrong core size, wrong paper type, or poor storage can waste money and ruin records. This guide covers every spec, brand, and decision you need to buy the right fax paper in 2026.
Frequently Asked Questions
What size fax paper do I need?
Almost all US fax machines use 8.5-inch wide thermal rolls (8.5" × 98' or 8.5" × 164') with a 0.5-inch inner core diameter. Check your machine's manual to confirm the core size before ordering. Plain-paper fax machines use standard Letter-size (8.5" × 11") cut sheets.
Does fax paper expire or fade?
Yes. Thermal fax paper has an image life of 5–7 years under ideal conditions (cool, dark, dry storage). Exposure to heat, UV light, skin oils, or PVC sleeves can cause fading within months. For records you need to keep, scan to PDF or photocopy onto acid-free paper immediately.
Is thermal fax paper BPA-free?
Most retail fax paper sold in the US since 2023 is BPA-free. However, BPS — a common BPA substitute — carries similar health risks. Look for "phenol-free" labeling (Terminal Depot, some ThermalPaperDirect lines) for the safest option.
How many pages does a fax paper roll hold?
A standard 8.5" × 98' roll yields approximately 107 Letter-size pages. An 8.5" × 164' roll yields about 179 pages. A 328' jumbo roll gives approximately 358 pages.
Can I use any thermal paper in my fax machine?
As long as the width (8.5") and core inner diameter (usually 0.5") match your machine, generic thermal paper works fine. Sensitivity grade (standard, high, ultra-high) affects image quality but all grades are compatible — higher sensitivity produces bolder output.
