The fonts arduino.cc draws
| Font | Used for | Share of its custom-font text | Licence | How common |
|---|---|---|---|---|
| Open Sans | Headings, Body text | 93.4% | Open source | 26 of 845 sites (rank 3) |
| Roboto Mono | Smaller text | 6.6% | Open source | 4 of 845 sites (rank =32) |
Share is how much of the page’s custom-font text each font draws. System fonts and icon fonts are never counted. Each site was opened twice in a real browser and Chrome was asked which font file drew each piece of text. We count a font for a site only if both runs saw it and it drew at least 2% of the site’s custom-font text. The full method.
