Paper Sizes
The A-standard paper sizes, based on the international ISO 216 standard, offer a systematic and widely adopted range for various printing and document purposes. The series starts with the A0 size, and subsequent sizes follow a halving principle as the page reduces in overall size:
- A0: 1189 x 841 mm
- A1: 841 x 594 mm
- A2: 594 x 420 mm
- A3: 420 x 297 mm
- A4: 297 x 210 mm
- A5: 210 x 148 mm
- A6: 148 x 105 mm
- A7: 105 x 74 mm
A4 is by far the most used paper size and is widespread in everyday printing needs such as letters, reports, and standard documents. A5 is commonly used for booklets, brochures, and smaller publications, as it offers a compact and readable format. A6 is often used for postcards and smaller promotional materials, while A7 is ideal for smaller-scale items like tickets or invitations.
The A-standard paper sizes provide versatility across a scalable range that ensures compatibility and consistency across a broad range of printing applications.
