Developer Reference Datasets

Developer Reference Datasets: aspect ratios, WCAG contrast, MIME, encoding, QR, format support

Open, reproducible lookup tables that web and app developers reach for constantly — computed from first principles, not scraped, so every value is exact and re-runnable. CC BY 4.0.

Quick answers (straight from the data)

  • What is 16:9 in pixels? 1920×1080, 1280×720, 3840×2160. 9:16 (Stories, Reels, TikTok) is those flipped. → aspect-ratios, resolutions
  • What contrast ratio does WCAG require? 4.5:1 for normal text (AA), 3:1 for large, 7:1 for AAA. #6b7280 on white is 4.83 (passes AA); #9ca3af is 2.54 (fails). → wcag-contrast-pairs, wcag-on-white-black
  • How many bytes is a character? In UTF-8: Latin 1, accented/Greek/Cyrillic 2, CJK 3, most emoji 4 (a flag emoji is 8 bytes / 2 code points). → encoding-sizes
  • What is the MIME type / magic number of a file? Extension → MIME type + byte signature, with the offset (RIFF/ISO-BMFF/tar signatures are not at byte 0, which most lists get wrong). .docx is a ZIP (PK). → file-types
  • How many characters fit in a QR code? A version-1 QR holds 41 digits / 25 alphanumeric / 17 bytes at ECC level L; up to 7,089 digits at version 40. Computed from ISO/IEC 18004, verified. → qr-code-capacity
  • Which browsers support AVIF / WebP / JPEG XL? AVIF is fully supported since Chrome 85, Firefox 93, Safari 16.4; JPEG XL is fully supported nowhere. → image-format-support
  • Plus favicon/app-icon sizes per platform and current social-media image sizes (date-stamped).

Why it's trustworthy

These are exact answers from the spec, not measurements. An aspect ratio, a WCAG contrast ratio, a UTF-8 byte count and a QR capacity are computable — so the CSVs are computed and re-runnable, and checkable against any online tool.
