What is the difference between 30×40 and 50×70?

A 50×70 cm poster covers 2.9 times as much wall as a 30×40 — but costs only 120 kr more. 3,500 cm² against 1,200 cm², DKK 399 against DKK 279. Measured by area, 50×70 is the cheapest size we have.

Why the price does not follow the size

The posters are printed to order, and a larger sheet costs only a little more to print and ship than a small one. That is why the price rises far more slowly than the area. It is the same mechanism that makes the second poster in a parcel cost almost nothing extra in shipping — and why three posters give you more wall for your money than one.

Choose 30×40 when

  • the poster is part of a group or a gallery wall
  • the wall is narrow — a hallway, between two doors, above a sideboard
  • you would rather have three motifs than one

Choose 50×70 when

  • the poster hangs alone on a free wall
  • it hangs above a sofa or a bed — see poster size above a sofa
  • the motif has a lot of detail, such as architecture and city scenes

The A sizes

A2 and A3 are the European standard formats. They are slightly narrower than 45×60 and 30×40, and they therefore fit frames you already own if those were bought as A sizes. If in doubt, choose 30×40 or 50×70 — they are the easiest to find frames for in Denmark.

One caveat

Prices are as of 5 August 2026 for unframed posters and may change. Price per 100 cm² is calculated on the full sheet size, not on the visible motif: if the poster sits in a frame, the frame covers 4-5 mm all the way round.
