This is the normal-width family of the system. According to the official notes it was rebuilt in 2020 as a variable font with two axes, weight from 100 to 900 and width from 50 to 125, so one file reaches from narrow settings to expanded ones wider than the default of 100. Roman and italic each have nine named weights, Thin to Black, which gives 18 styles. The fonts hold 893 glyphs across the Latin, Latin Extended and Vietnamese character sets.

Software that ignores the named instances shows Thin, so set the weight explicitly, for example font-weight: 400. - **Two axes in two files**: The download holds one variable file for the roman and one for the italic. Each contains both the weight axis and the width axis. - **Width 100 is the normal width**: Values below 100 narrow the letters down to 50, and values above it expand them up to 125. ## FAQs ### Is Saira free for commercial use?
