Cassette was measured as displaay.net, October 23rd draws it: its proportions, the width of every letter and figure, its weight, its stroke contrast and the shapes of telling letters like a, g, R and Q. The same measurements were taken of 1,506 free fonts, and these came closest. Each match was then checked by eye.
Not if you use the CSS on this page. It sets Google Sans 1.8% larger with a touch less letter-spacing, so text written for Cassette keeps its x-height and its line lengths, and lines break in the same places.
