Questions and answers

Frequently asked questions

How big is a 21x30 poster?

The poster measures 21 x 30 cm. Framed, it is slightly larger depending on the width of the frame.

Is 21x30 the same as A4?

Almost. A4 measures 21 x 29.7 cm, and an A4 print fits a 21x30 cm frame. Our 21x30 posters and frames are the A4 format.

Why do some posters have a white border?

Some prints have a white border that is part of the design and printed directly on the poster. The poster always measures 21 x 30 cm, with or without a white border, so it fits a standard 21x30 frame.

Is a frame included?

No, the poster is delivered without a frame. You can add a frame right on the product page or choose from our frames in 21x30 cm.

What paper do you print on?

Our posters are printed on 200 g/m² premium matte paper that is FSC®-certified and archival quality, so it won’t yellow over time.

Can I return my order?

Yes, you have 90 days from delivery to return your order.
