A Measurement Tool for Text Width

This app allows a Web developer to compare in detail two or more font definitions, whose properties may include font family, size, letter spacing, and word spacing. An optional text string may be entered for evaluation; lacking this, a Latin character set string will be used. Results include width ratio, EM width of the test string, mean character width, and a visual comparison of the formatted strings. Note — This app will not perform well with font size smaller than 0.25em or greater than 4 em
