When ordering with a passepartout (white frame inside) you will get a frame one size up to the size you choose to make space for the passepartout. Posters do not come framed.
With Passepartout:
21x30cm print + passepartout = 30x40cm frame size
30x40cm print + passepartout = 40x50cm frame size
40x50cm print + passepartout = 50x70cm frame size
50x70cm print + passepartout = 70x100cm frame size
