Poster Sizes — A3 to A0

Short answer

Plan a poster in a standard A-series or custom format around the available space, reading distance and content. Confirm the paper, finish, mounting or frame and image quality at the final printed size before ordering.

A poster can present a menu, promotion or event message on a wall or display. The useful size depends on the space and how much text must be read. This page helps prepare a brief covering dimensions, image quality, lighting, protection and mounting.

Choosing a size

Measure the available display area and identify where people will read the poster. A detailed menu and a short event headline need different layouts even at the same paper size. Compare A3, A2, A1, A0 or a custom format using the actual content; confirm that the frame or mounting system fits the selected dimensions.

Matte or gloss, and when lamination pays

Compare matte and gloss samples under lighting similar to the intended display. Reflection and colour appearance depend on the paper, finish and angle; matte material does not eliminate every reflection. Decide whether handling, cleaning or moisture exposure calls for a compatible protective finish. Confirm its limits, including the treatment of exposed edges.

Agree protection for the actual use

Artwork and resolution

Send original images and vector logos where available. Image resolution is checked at the final output dimensions and intended viewing distance; changing the dpi label does not restore missing detail. Ask for the printer’s file requirements and the actual frame or trim allowances. Keep essential text clear of the agreed concealed or cut areas.

Frequently Asked Questions

What size should a menu poster be?

Choose the format from the amount of menu text, available space and reading distance. Review the complete layout at scale; a standard paper size alone does not establish readability.

Is a frame necessary?

No, a poster can be mounted directly on a wall or held in a rail. A frame is worth it when the poster stays for a long time and you want a tidier look.

Will a poster work in a shop window?

Check sunlight, reflections, moisture and the planned display period. Confirm a suitable paper or film and mounting method; fading has no universal timetable, and the same material can behave differently in different windows.

How quickly can it be produced?

Timing is confirmed after checking the artwork, quantity, material, finishing and any frame requirements. Include the date by which the poster must be installed or collected.

Does a larger run reduce the price?

Request quotes for the quantities you are considering. Unit cost depends on print setup, material, format, finishing and packing; compare the total and per-item prices for the same specification.

My photo is low resolution — will it work?

Send the original file and required print dimensions. We can review the available pixels and intended viewing distance, then discuss resizing, a replacement image or a sample; enlarging a small file does not create real detail.
