Geo Circle Open

Geo Circle Open's lowercase x reaches 69.4% of the capital height, close to the 71.1% median for sans serif fonts, level with the lowest of the 17 sans serif 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 30.6% of the cap height below the baseline, deeper than 15 of the 16 other sans serif fonts. Geo Circle Open runs 25% wider than the median for sans serif fonts: an average lowercase letter, spacing included, is 121.4% as wide as the capitals are tall (an average capital, 122.2%). The o is wider than it is tall, 1.27 to 1, and M and W are the widest capitals, at 1.12 times the width of H. The O stops 4.1% of the cap height short of H and stands 4.1% above the baseline.

The letters stand upright, with no measurable slant. Vertical stems measure 8.1% of the cap height, lighter than 11 of the 16 other sans serif fonts. Ink covers 15% of each lowercase letter's box (its advance width by the cap height), the lightest of all 17 sans serif fonts.

Its 332 characters include 161 Arabic and 116 Latin letters, plus 55 figures, punctuation marks and symbols; 64 of the Latin letters are accented or special forms beyond A to Z. The word space measures 59.2% of the cap height, and the blank space either side of a lowercase letter takes up 34.1% of its width. The font carries no kerning, so spacing comes from each letter’s own side bearings. Its OpenType tables also hold Arabic joining forms (init, medi, fina) and mark positioning for accents and vowel signs (mark, mkmk). All ten figures share one width, so columns of numbers line up.
