How to Choose the Right Paper Size for Your Printing Job

A4 is the standard choice for letters, assignments, reports, forms and most office documents. This guide explains the practical checks that matter most.

A4 for everyday documents

A4 is the standard choice for letters, assignments, reports, forms and most office documents. It gives enough room for readable text without feeling oversized.

A5 for handouts and compact flyers

A5 is half the size of A4. It works well for promotional handouts, small menus, programmes and information customers can carry easily.

A3 for visibility

A3 is twice the size of A4 and is useful for notices, classroom material, price lists and posters that need to be read from a short distance.

Business cards need a dedicated layout

Do not shrink an A4 design into a business card. Cards need larger text relative to their size, safe margins and a simple message.

Match size to viewing distance

The farther away the reader will be, the larger the text and finished item should be. A design meant for a desk is different from one displayed on a wall.

Ask before designing

Confirm the final size with the printer or designer first. Designing at the correct dimensions reduces cropping, distortion and last-minute adjustments.
