About
Its x-height is 70.2% of the cap height, near the 70.2% typical of monospace fonts in the library, taller than 10 of the 19 other monospace fonts. Ascenders on b, d, h, k and l line up with the capitals (100% of their height), and descenders on g, j, p, q and y drop 29.8% of the cap height below the baseline, shallower than 10 of the 19 other monospace fonts. It sets wide: an average lowercase letter, spacing included, is 90.6% as wide as the capitals are tall (an average capital, 90.6%), 5.3% more than the median for monospace fonts, so the same words take a longer line. The o is close to a circle, 0.98 times as wide as it is tall, and every capital has the same width. O stands exactly as tall as H and sits on the baseline, with no overshoot.
The letters stand upright, with no measurable slant. Vertical stems measure 10.5% of the cap height, heavier than 10 of the 15 other monospace fonts. Ink covers 23.3% of each lowercase letter's box (its advance width by the cap height), lighter than 10 of the 19 other monospace fonts. Strokes keep one thickness in every direction: the sides of o and O measure the same as their tops and bottoms.
Its 159 characters include 116 Latin letters, plus 43 figures, punctuation marks and symbols; 64 of the Latin letters are accented or special forms beyond A to Z. The word space measures 43.6% of the cap height, and the blank space either side of a lowercase letter takes up 28% of its width. The font carries no kerning, so spacing comes from each letter’s own side bearings. The figures have different widths, so columns of numbers set in Slab Industrial Mono will not line up exactly.
Measured from the version 0.1.1 font file. Comparisons are with the 314 library fonts measured on October 2, 2026, 20 of them monospace fonts.
