About ADA Font Check

ADAFontCheck determines if a font meets U.S. Federal and California ADA accessibility regulations for tactile and visual signage using opentype.js

ADA Tests Overview

ADAFontCheck perfoms the following tests:

  • Character Stroke Width ratio using the uppercase letter 'I'.
  • Character Body Width ratio using the uppercase letters 'I,' 'H,' and 'O'.
  • Italic Font detection.
  • Serif Font detection.
  • Sans Serif Font determination.
  • Fonts must meet the ratio requirements of both Tests 1 and 2 for ADA compliance.
  • Numerals are not tested for compliance but are considered compatible when used with letters of the same font set and size.

How to use ADAFontCheck

  1. Select “All Fonts” to display both Pass and Fail fonts. Select “ADA Fonts Only” to display just Pass fonts.
