How were these alternatives chosen?
By measuring the letters, not by comparing names or tags. Algebra was measured as commercialtype.com, 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.
Will Sentient change my layout?
Not if you use the CSS on this page. It sets Sentient 4.2% larger with a touch less letter-spacing, so text written for Algebra keeps its x-height and its line lengths, and lines break in the same places.
Spot Algebra 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.
