Button Size Chart

Courtney & Co button makers have created a Button Size Chart that can help you to communicate accurately with suppliers and manufacturers 

The unit of measuring a button is known as ‘ligne’ (pronounced ‘line’ in English) which dates back to the 9th century and pre-dates the metric system.

This chart shows ligne sizes together with their equivalent in millimetres and inches and relates to the diameter of buttons.
