Sans fonts with at least 8 styles available on Google Fonts are compared here; those with 4-7 styles are compared here. This page compares those with 2-3 styles, which means that you might not be able to use bold, italic, or bold italic. It's probably best to use a font with more styles for your main text; these might be better for titles or short pieces of content. Same with the fonts that have only a single style, which are compared here.

The glyphs are 'trispaced.' It means that the space are modular, 250, 500, 750, this allow a better spacing between characters, but allow also a vertical alignment similar to the one possible with a monospaced font. We were thinking it was a bright new idea, but we discovered that was usual for Olivetti typewriters working with 'Margherita.'
