- Keep text and logos 10mm inside the trim
- 150 DPI at final size is fine for posters viewed from a distance; use 300 DPI for A3 and smaller
- Avoid enlarging web images — check the physical size with our print size estimator first
- RGB files are converted to CMYK for press, which can shift bright blues, greens and oranges
- 170gsm silk or gloss coated paper
- A3 (297 × 420mm)
A3 posters are the standard window and noticeboard size across the UK, which means they fit almost every off-the-shelf poster frame and snap frame you will encounter.
Printed on 170gsm so they hang flat rather than curling. For anything displayed outdoors or in a window with strong sun, expect to refresh them — poster stock is not UV-stable in the way that a rigid sign is.
- From 170gsm
- Gloss, silk or uncoated
- UK production
A3 Posters 170gsm buying guide
Written by our studio team — what to choose, and what usually goes wrong.
- A6 — pocket and handout size. Cheapest per unit, best for door drops and event flyering.
- A5 — the workhorse. Enough room for an offer plus a small amount of detail; still cheap to post.
- A4 — menus, price lists and anything with a table or lots of copy.
- DL (99 x 210mm) — fits a standard envelope and a leaflet rack, ideal for direct mail.
