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.
Can I use the same fonts?
- Roobert is sold under a commercial licence by Displaay Type Foundry. Licence it from Displaay Type Foundry; copying the file from a site that uses it is not a licence.
- JetBrains Mono is open source and free to use, including commercially. Get it from Google Fonts.
- Family: we could not verify that this typeface can be licensed, so we neither recommend it nor link a source.
