Carbon Typewriter

Carbon Typewriter's lowercase x reaches 69.5% of the capital height, close to the 70.2% median for monospace fonts, lower than 13 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 31.2% of the cap height below the baseline, deeper than 14 of the 19 other monospace fonts. Its letters are of average width for monospace fonts: an average lowercase letter, spacing included, is 86% as wide as the capitals are tall (an average capital, 86%), within 0% of the median. The o is close to a circle, 1.00 times as wide as it is tall, and every capital has the same width. Round letters overshoot: O rises 3.2% of the cap height above H and dips 1.6% below the baseline.

The letters stand upright, with no measurable slant. Vertical stems measure 8.6% of the cap height, lighter than 12 of the 15 other monospace fonts. Ink covers 20.5% of each lowercase letter's box (its advance width by the cap height), lighter than 14 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 148 characters include 105 Latin letters, plus 43 figures, punctuation marks and symbols; 53 of the Latin letters are accented or special forms beyond A to Z. The word space measures 86% of the cap height, and the blank space either side of a lowercase letter takes up 28.7% of its width. The font carries no kerning, so spacing comes from each letter’s own side bearings. All ten figures share one width, so columns of numbers line up.
