Paper comes in many sizes, but the most widely recognized worldwide is the ISO 216 standard paper size system, which includes A0, A1, A2, A3, A4, and smaller variations. Understanding paper dimensions is crucial when printing documents, creating designs, or preparing academic and office materials.
In Malaysia, the most commonly used size is A4 paper (210mm × 297mm), but other formats are equally important depending on the purpose.
A-Series Paper Sizes (ISO 216 Standard)
The A-series is based on a consistent aspect ratio of 1:√2, making it easy to scale documents up or down without distortion.
Here are the standard paper dimensions:
| Paper Size | Dimensions (mm) | Dimensions (inches) | Common Use Cases |
|---|---|---|---|
| A0 | 841 × 1189 mm | 33.1 × 46.8 in | Posters, engineering drawings |
| A1 | 594 × 841 mm | 23.4 × 33.1 in | Flip charts, technical diagrams |
| A2 | 420 × 594 mm | 16.5 × 23.4 in | Calendars, large prints |
| A3 | 297 × 420 mm | 11.7 × 16.5 in | Presentations, diagrams |
| A4 | 210 × 297 mm | 8.3 × 11.7 in | Office documents, school papers |
| A5 | 148 × 210 mm | 5.8 × 8.3 in | Flyers, small notebooks |
| A6 | 105 × 148 mm | 4.1 × 5.8 in | Postcards, invitations |
