Receipt Paper Size Guide: Width, Length, Diameter & Core
A paper-roll description contains several dimensions. Understanding each one helps prevent ordering a roll that is too wide or too large for the printer.
Quick answer: Start with paper type and width. Then verify outside roll diameter, roll length, and core size. A matching width alone does not guarantee the roll will fit.
What Each Measurement Means
| Specification | Meaning | Why it matters |
|---|---|---|
| Width | Side-to-side measurement of the paper. | The roll must fit the printer's paper path. |
| Length | How many feet or meters of paper are wound on the roll. | Longer rolls last longer but may create a larger outside diameter. |
| Outside diameter | Total diameter of the finished roll. | The printer compartment must physically accommodate it. |
| Core size | Diameter/design of the tube or center opening. | Can affect fit in devices with spindles or tight paper paths. |
| Paper type | Thermal, bond, carbonless, etc. | Must match the printer technology. |
How to Measure an Existing Roll
- Measure the paper width across the face of the roll.
- Measure the outside diameter from edge to edge through the center.
- Check the core opening or core specification.
- Read any size information printed on the box or wrapper.
- Confirm the printer model and compare its media specification.
