Art prints come in the two different paper size and they both have 10mm white border around.

My suggestions for framing and mating would be:

  • Paper size: 150 x 200 mm (5,9 x 7,8 in)

    Frame size : 20 x 25 cm (8 x 10 in)

    Window mat opening size : 12,5 x 17,5 cm (6 x 8 in)*

  • Paper size: 210 x 297 mm A4 (8.3 x 11.7 in)

    Frame size:

    • 28 x 35 cm (11 x 14 in) or

    • 30 x 40 cm (12 x 16 in)

    Window mat opening size: 18 x 27 cm (7 x 10,5 in)*

* Please note! If you choose different frame, the size of opening window mat stays always the same!
