Atrium Sans

With an x-height of 74.6% of the cap height, its lowercase stands above the 71.1% median for sans serif fonts, taller than 14 of the 16 other sans serif fonts. Ascenders on b, d, h, k and l rise 4% above the capitals, and descenders on g, j, p, q and y drop 27.8% of the cap height below the baseline, shallower than 12 of the 16 other sans serif fonts. It sets narrow: an average lowercase letter, spacing included, is 63.8% as wide as the capitals are tall (an average capital, 73.2%), 34.3% less than the median for sans serif fonts, so more words fit on a line. The o is an upright oval, 0.85 times as wide as it is tall, and W is the widest capital, at 1.30 times the width of H. Round letters overshoot: O rises 1.3% of the cap height above H and dips 1.3% below the baseline.

The letters stand upright, with no measurable slant. Vertical stems measure 7.4% of the cap height, lighter than 13 of the 16 other sans serif fonts. Ink covers 23.2% of each lowercase letter's box (its advance width by the cap height), darker than 11 of the 16 other sans serif 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 28.7% of the cap height, and the blank space either side of a lowercase letter takes up 15.3% of its width. Spacing is adjusted with 146 kerning pairs, more than 15 of the 16 other sans serif fonts. The tightest of them is AY, which closes up by 19.1% of the cap height. The figures have different widths, so columns of numbers set in Atrium Sans will not line up exactly.
