Converteer tussen elk standaard papierformaat — ISO A0–A10, B-serie, C-serie, US Letter/Legal/Tabloid en Japanse JIS — in mm en inches.
| Formaat | mm | cm | inches | Oppervlak (cm²) |
|---|
De ISO A-reeks begint bij A0 = 841 × 1189 mm (1 m² oppervlak, √2-verhouding). Elk volgend formaat halveert de langste zijde. De B-reeks is het geometrisch gemiddelde van opeenvolgende A-formaten, en de C-reeks past precies om A heen (gebruikt voor enveloppen).
De schaalverhouding is min(B.b/A.b, B.h/A.h) — de grootste factor waarmee A binnen B past zonder af te snijden. 1 inch = 25,4 mm.
