How to get the true size of thermal paper roll

It’s the key point to confirm thermal paper roll size when you choose receipt roll for your thermal printers. You can find the correct size easily on the printer instructions. However, We compiled this guide to help you measure the correct pos roll.

ROLL WIDTH

The width is the first dimension of the paper roll. This measurement is taken from one edge to the other edge across the face of the paper roll. If possible, let the measurement be in millimeters for accuracy, keep in mind that any slight variation in size can cause serious problems.

ROLL DIAMETER

When measuring the diameter of the roll, you must measure from edge to edge; going straight across the center of the core.

PAPER ROLL LENGTH

The length of the roll paper is only clearly stated on the packaging when it is sold in a few countries, such as Russia, and the USA. If the paper rolls are of the same diameter, the longer the length is, the more durable it is, the end users don’t need to change the roll paper frequently.

CORE SIZE

The inner diameter of the core is important because some printers use a shaft to pass through the core to support the paper roll. The regular core inner diameter is 13mm.

The outside diameter of the core is not as important as the inner diameter, but it affects the diameter or length of the paper roll.

In summary, we usually describe the roll size by:

ROLL WIDTH*ROLL DIAMETER*CORE INNER DIAMETER

ROLL WIDTH*PAPER ROLL LENGTH*CORE INNER DIAMETER
