Thin and hairline fonts for light, airy headings
Families with a Thin weight and single-style hairline display faces, for large headings, covers and minimal layouts.
So very light
Thin type is a matter of scale. A hairline weight is drawn so that its strokes look right at 60, 100 or 200 points, where a regular weight would look heavy and a bold would look crude. Set that large, a thin face is striking: all outline and white space, calm and expensive-looking. It has become a signature of cosmetics, architecture, technology launches and wedding stationery.
The limits are just as clear, and they are physical. Below roughly 24 pixels a hairline stroke may be less than one pixel wide, so it turns gray and broken on ordinary screens. On paper, thin strokes fill in when reversed out of a dark color and vanish on textured stock. Contrast becomes critical: light gray thin text on white fails accessibility checks long before a regular weight would. So use these weights for a few large words, on a plain background, in a color with strong contrast.
There are two ways to get the look. A family with a Thin or ExtraLight weight gives you matching heavier styles for the rest of the page. Single-style hairline display faces have more personality but need a separate companion for text.

Questions about thin and hairline fonts for light, airy headings
How large must thin fonts be to stay readable?
On screens, hairline weights generally need 32 pixels or more, and larger on low-density displays. In print they hold at smaller sizes on smooth, coated paper.
Why does my thin text look gray on screen?
The strokes are narrower than a pixel, so the display blends them with the background. Increase the size, choose the next weight up, or raise the color contrast.
Can I use these thin fonts in commercial designs?
Yes. All but one are under the SIL Open Font License, and one slab serif is under the Apache License 2.0. Both allow commercial use, embedding and modification.
