About our A3 posters
A3 is the poster size that goes almost anywhere. At 29.7 by 42 cm it is big enough to read from a few steps back, yet small enough for a noticeboard, a shop counter wall or a standard display frame. We print yours in full colour on your choice of stock, from a light 130gsm sheet up to a substantial 250gsm, in gloss, matte, silk or uncoated finishes. Choose single or double-sided, and add lamination or UV coating when the poster will be handled, or mounting when it has to stand on its own. It is the practical, affordable size for promotions you put up in numbers.

What businesses use them for
A3 posters are the everyday workhorse for visible, low-cost promotion. Nigerian businesses use them for in-store offers and price lists, event and church programmes, school charts and wall displays, product launches, and notices on office and shop boards. Because you choose the stock and finish, the same product covers a quick paper promo and a laminated poster meant to stay up for months. Pair it with an A3 snap frame when you want to swap the message often.

FAQ
How big is an A3 poster?
29.7 by 42 cm, which is 11.7 by 16.5 inches (297 by 420 mm). It is one size up from A4 and one down from A2.
Which stock should I choose?
Lighter 130gsm suits short-run promos; 250gsm feels premium and lasts longer. Gloss makes colours pop, matte and silk look more refined, uncoated suits a natural finish.
Can I get it laminated?
Yes. Lamination or UV coating protects the surface and is worth adding if the poster will be handled or kept up for a long time.
Will it fit a standard frame?
Yes. A3 is a standard size, so it fits A3 display frames and our A3 snap frames, which let you change the poster without removing the frame.
