Groove Serif 3D

The x-height is a compact 73.2% of the cap height, below the 76.2% median for display fonts, lower than 66 of the 97 other display 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 26.9% of the cap height below the baseline, deeper than 77 of the 97 other display fonts. It sets wide: an average lowercase letter, spacing included, is 94.1% as wide as the capitals are tall (an average capital, 104.4%), 5.3% more than the median for display fonts, so the same words take a longer line. The o is wider than it is tall, 1.16 to 1, and W is the widest capital, at 1.05 times the width of H. The O rises 0.9% of the cap height above H and sits on the baseline.

Ink covers 46.6% of each lowercase letter's box (its advance width by the cap height), darker than 66 of the 97 other display fonts. Each letter carries a solid 3D extrusion joined to its face.

Its 501 characters include 105 Latin, 73 Thai, 69 Greek, 67 Devanagari, 66 Cyrillic, 36 Arabic and 27 Hebrew letters, plus 58 figures, punctuation marks and symbols; 53 of the Latin letters are accented or special forms beyond A to Z. The word space measures 35% of the cap height, and the blank space either side of a lowercase letter takes up 6.6% of its width. Spacing is adjusted with 215 kerning pairs, more than 82 of the 97 other display fonts. The tightest of them is AV, which closes up by 29.8% of the cap height. Its OpenType tables also hold Arabic joining forms (init, medi, fina), Devanagari conjuncts and vowel signs (half, rphf, blwf and more), mark positioning for accents and vowel signs (mark, mkmk), ligatures (liga, dlig) and glyph composition (ccmp, locl). The figures have different widths, so columns of numbers set in Groove Serif 3D will not line up exactly.
