Harmattan Arabic Font: Size and Variable File
Harmattan needs 261.9 KB for Arabic regular and bold: rank 20 of 20, heavier than the sample median of 54.0 KB. The selected Fontsource source has no variable file. Latin makes up 7% of the mixed-script total. Every figure on this page comes from the August 23, 2026 WOFF2 snapshot.
What the measurements say about Harmattan
- It is 2.1× the Naskh median of 126.7 KB.
- Switching to Markazi Text, the smallest Naskh family, would save 216.9 KB (83%) for the same two weights.
- The selected Fontsource source has no variable Harmattan file, so every extra weight is another static download of roughly 131.0 KB.
- Latin is only 7% of the mixed-script total (20.8 KB); the Arabic glyph set dominates the payload.
- Unusually, bold is 2% smaller than regular (129.4 KB vs 132.5 KB).
Size rank and delivery totals
Rank 20 of 20 overall and 7 of 7 in Naskh, smallest first by Arabic 400+700 bytes. Ties share a rank. Measured on . Starting role (editorial guidance): Compact reading.
| Scenario | Exact bytes | Meaning |
|---|---|---|
| Arabic 400 + 700 | 268,188 | Two static WOFF2 files |
| Arabic + Latin 400 + 700 | 289,444 | Four static WOFF2 files |
| Added Latin bytes | 21,256 | Mixed-script total minus Arabic total |
| Arabic variable weight file | Not in selected source | One variable Arabic file, when available |
| Variable minus static | Not applicable | Compared with Arabic 400+700; negative means smaller |
Variable totals cover the selected Arabic weight-variable file, without a Latin variable file. Availability describes this snapshot’s package source. File sizes exclude CSS and do not predict latency, caching, rendering time or layout shift.

The benchmark measures filesystem bytes of normal 400 and 700 Arabic-subset WOFF2 files from installed Fontsource packages. It separately sums Latin files and records the Arabic variable file where available. The preview is a visual aid; readability is not scored.
Questions and answers
How large is Harmattan for Arabic regular and bold?
The Arabic 400 and 700 WOFF2 files total 268,188 bytes (261.9 KB), rank 20 of 20 measured families. Adding Latin brings it to 289,444 bytes. These are file sizes, not page-load timings.
Should I use the variable version of Harmattan?
The selected Fontsource source has no variable Harmattan file, so every extra weight is another static download of roughly 131.0 KB.
Does Harmattan cover Persian and Urdu letters?
Harmattan's declared Unicode ranges include the Persian (U+067E) and Urdu (U+0679) letters tested, passing 7 of 7 representative checks. All 20 measured families pass the same checks, so coverage does not separate them; test shaping with your own text.
