Printer Paper Formats Explained: DIN A4, A3, A5 and Special Formats
DIN A4 is the standard in the office. DIN A3 is used for plans, tables, and presentations. DIN A5 is suitable for cards, small forms, and flyers.
Anyone who regularly orders paper should pay attention not only to grammage and quality, but also to the correct format. This prevents wrong purchases, simplifies procurement and ensures that printers, copiers and filing systems match.
Short Answer
For normal office use, DIN A4 is the right choice. DIN A3 is suitable for large printouts, plans, and presentations. DIN A5 is practical for small forms, cards, or notepads. Special formats should only be chosen if the printer and application are compatible.
The most important paper formats in the office
| Format | Typical Use | Recommendation |
|---|---|---|
| DIN A4 | Letters, invoices, copies, contracts | Standard for almost every office |
| DIN A3 | Plans, tables, posters, presentations | for large printouts and better overview |
| DIN A5 | Cards, small forms, flyers | for compact information |
| Special formats | Labels, photo paper, cards, special prints | only use with printer approval |
DIN A4: The Office Standard
DIN A4 is the most important paper format in companies. It fits letters, invoices, offers, delivery notes, forms and most printers and copiers. For daily consumption, DIN A4 copy paper is usually the most economical solution.
DIN A3: When more space is needed
DIN A3 is twice as large as DIN A4 and is suitable for plans, larger tables, notices, drafts and presentation documents. It is important that the printer or copier supports the format.
DIN A5 and smaller formats
DIN A5 is frequently used for small forms, cards, flyers, notepads or compact information sheets. In everyday office life, it is less of a standard than DIN A4, but can be very practical for certain applications.

Which paper quality matches the format?
The format does not yet say anything about the paper quality. For daily printouts, 80 g paper is often sufficient. For offers or presentations, 90 g or 100 g paper can appear higher quality. Recycled paper is a sensible solution for more sustainable procurement.
