Guide to Button Ligne Sizes

Guide to Button Ligne Sizes

Button sizes are typically measured in Ligne, which can be abbreviated to L.
The measurement refers to the button diameter, or the largest diameter of irregular button shapes.

40 Ligne, or 40L equals to 1 inch (1") diameter, which equates to 25.4mm (2.54cm).
For simplicity, we have rounded to the nearest millimetre, so 1 inch = 25mm

Therefore, we use these measurements as a rough guide for button sizes;

10L = 6mm (1/4")
20L = 12.5mm (1/2")
30L = 19mm (3/4")
40L = 25mm (1")

We have also put together this handy little reference table, for Buttons Sizes from 10 Ligne to 48 Ligne.

For those who are interested in the more accurate sizes;

10L = 1/4" = 6.35mm
20L = 1/2" = 12.7mm
30L = 3/4" = 19.05mm
40L = 1" = 25.4mm
