Braille Cell Dimensions

Marburg Medium braille has been specifically designed for use on pharmaceutical packaging. There are other standards that have been created for specific applications.

The table below contains a summary of the different braille dimensions used in the major braille producing countries and for specific applications. Marburg Medium is the only one recommended for pharmacutical packs.
