How to Choose the Right Thermal Paper Roll Size
Choosing the correct thermal paper roll size ensures your POS system prints smoothly and your receipts look professional. Every printer or terminal has specific requirements, and using the wrong size can cause paper jams, fading, or alignment issues.
The two most common sizes are 2¼" (57 mm) and 3⅛" (80 mm). Smaller 2¼" rolls fit compact terminals used in retail counters, cafés, and payment machines, while 3⅛" rolls are often used in full-size printers that generate longer or more detailed receipts.
To determine your roll size, check your POS printer’s specifications or measure your current roll’s width and diameter. You’ll also want to note the core size—usually ½" or ⅝"—as this ensures a proper fit inside your device.
