Four extensions, two real formats, and one decision that matters more than all of them. What to serve on the web, what to install, and why the file you ship should not be the file you sell.
Eight properties that separate a page somebody set from a page that used the defaults. Fluid sizes, optical tracking, tabular figures, and the two lines that fix every table of numbers.
A variable font holds a whole design space in one file. It is bigger than one static weight and smaller than three, so the break-even is around two — and optical size is the axis worth having.
Interface text is small, read in a hurry, and often a single word. The rules for buttons, form fields, error messages and numerals are not the rules for articles.
Typefound's free poster tool sets type over your own image entirely in the browser — there is no endpoint on the site that accepts a picture, so nothing is uploaded, and the export is a PNG at the original size.
