Paper size converters translate between A, B, C series (ISO 216), letter, legal, and other paper format dimensions.
Formel
A0 = 841 × 1189 mm (√2 aspect ratio), each lower size halves area
- A0
- 841 × 1189 mm (√2 aspect ratio) — 841 × 1189 mm (√2 aspect ratio)
Schritt-für-Schritt-Anleitung
- 1A0 = 841 × 1189 mm (√2 aspect ratio), each lower size halves area
- 2A4 (210 × 297 mm) = US Letter (8.5 × 11 in) roughly equivalent
- 3US: letter, legal, tabloid; ISO: A, B, C series
Gelöste Beispiele
Eingabe
US Letter 8.5 × 11 inches
Ergebnis
215.9 × 279.4 mm (close to A4 210 × 297 mm)
Slightly different dimensions
Häufige Fehler vermeiden
- ✕Assuming US Letter and A4 are identical (they're slightly different)
- ✕Forgetting to adjust margins when changing paper format
Häufig gestellte Fragen
Why are ISO sizes standardized differently?
ISO √2 ratio maintains proportion when folding/scaling; easier for document handling and copying.
Do size conversions affect document layout?
Yes, US letter taller; margins may need adjustment when converting between US and ISO formats.
