Design
Window Arch Slab 3D up close
Window Arch Slab 3D has a dense black face with a close extrusion visible along the upper and right edges, giving each word the weight of a solid sign. The H has a firm crossbar and broad square feet; the O holds a tall, narrow opening with a rounded top; and the R repeats that opening above an angled leg. Its serifs meet the stems at crisp square corners, while the rounded bowls soften the otherwise blocky shapes. In the specimens, the compact spacing pulls short words into a dark, architectural band.

How this page was made. Window Arch Slab 3D is a FontGenerator library font made with AI; before release its letters were read back one by one by independent automated checks. The design notes were written by AI from the specimen images and checked against them by a second, independent pass; every number on the page is measured from the font file.

About
About Window Arch Slab 3D
With an x-height of 73.3% of the cap height, its lowercase stands above the 69.6% median for serif fonts, taller than 41 of the 52 other serif fonts. Ascenders on b, d, h, k and l line up with the capitals (98.8% of their height), and descenders on g, j, p, q and y drop 24.4% of the cap height below the baseline, shallower than 46 of the 52 other serif fonts. It sets narrow: an average lowercase letter, spacing included, is 75.2% as wide as the capitals are tall (an average capital, 81%), 9.6% less than the median for serif fonts, so more words fit on a line. The o is an upright oval, 0.84 times as wide as it is tall, and M is the widest capital, at 1.18 times the width of H. Round letters overshoot: O rises 2.5% of the cap height above H and dips 1% below the baseline.
Ink covers 44.8% of each lowercase letter's box (its advance width by the cap height), darker than 44 of the 52 other serif fonts. Each letter carries a solid 3D extrusion joined to its face.
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 41.9% of the cap height, and the blank space either side of a lowercase letter takes up 9% 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 Window Arch Slab 3D will not line up exactly.
Window Arch Slab 3D is Window Arch Slab with the 3D effect applied to every letter. Window Arch Slab 3D is drawn on the same letter structure as one other font in the library.
Measured from the version 0.1.1 font file. Comparisons are with the 377 published library fonts measured on October 14, 2026, 53 of them serif fonts.

- Structure
- Solid extruded 3D shadow behind the face of Window Arch Slab: Upright medium-width slab serif with substantial square unbracketed slab serifs: every serif joins its stem directly with a crisp ninety-degree meeting, including capitals, lowercase, numerals, and punctuation. Stems and bowls are solid black. B, D, P, R, b, d, p, q, and the enclosed interiors of a and g use one recurring tall window counter: straight vertical sidewalls rise into a rounded arch at the top, remain open inside the normal bowl, and return to the baseline without a bridge or outline. Use real lowercase proportions, a double-storey a, open e, conventional k fork, N diagonal, and a descender on g. No western spur, typewriter rhythm, inline, outline, shadow, stripe, stencil cut, floating serif, or heart decoration
