Is there a free version of Calibre?
No. Calibre is a paid sans serif from Klim Type Foundry. Every alternative on this page is free for commercial use, under the SIL Open Font License.
How were these alternatives chosen?
By measuring the letters, not by comparing names or tags. Calibre was measured as klim.co.nz 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.
Will Inter change my layout?
Not if you use the CSS on this page. It sets Inter 18.7% smaller, so text written for Calibre keeps its x-height and its line lengths, and lines break in the same places.
Spot Calibre in the wild?
Point Fontsight at any text on any website. It names the font, and offers a free look-alike you can try on the page, line breaks intact.
