Changa Arabic Font: Size and Variable File
Changa needs 21.7 KB for Arabic regular and bold: rank 3 of 20, one of the lighter families in the sample (median 54.0 KB). Its variable Arabic file only pays off at about 3 or more weights. Latin makes up 48% of the mixed-script total. Every figure on this page comes from the August 23, 2026 WOFF2 snapshot.
What the measurements say about Changa
- It sits at the Display median of 22.7 KB.
- It is the smallest Display family measured; the next one, El Messiri, is 2.0 KB (9%) larger.
- The variable Arabic file (22.5 KB) is 4% larger than the two static weights. Estimate: at about 10.8 KB per static weight, it pays off once you ship 3 or more weights.
- Latin adds 19.9 KB, 48% of the mixed-script total.
- Bold is 4% larger than regular (11.1 KB vs 10.6 KB).
Size rank and delivery totals
Rank 3 of 20 overall and 1 of 2 in Display, smallest first by Arabic 400+700 bytes. Ties share a rank. Measured on . Starting role (editorial guidance): Expressive headings.
| Scenario | Exact bytes | Meaning |
|---|---|---|
| Arabic 400 + 700 | 22,220 | Two static WOFF2 files |
| Arabic + Latin 400 + 700 | 42,564 | Four static WOFF2 files |
| Added Latin bytes | 20,344 | Mixed-script total minus Arabic total |
| Arabic variable weight file | 23,076 | One variable Arabic file, when available |
| Variable minus static | 856 (4%) | 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.

Comparisons involving Changa
Method and limits
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 Changa for Arabic regular and bold?
The Arabic 400 and 700 WOFF2 files total 22,220 bytes (21.7 KB), rank 3 of 20 measured families. Adding Latin brings it to 42,564 bytes. These are file sizes, not page-load timings.
Should I use the variable version of Changa?
The variable Arabic file (22.5 KB) is 4% larger than the two static weights. Estimate: at about 10.8 KB per static weight, it pays off once you ship 3 or more weights.
Does Changa cover Persian and Urdu letters?
Changa'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.
