30x40 cm picture frame in nice solid oak with a 20 mm wide wooden frame. You can buy it with 20 or 30 mm depth. The deep 20x30 mm frame is a bit more expensive.
If you want a narrower 30x40 oak frame, see our 12x18 mm narrow 30x40 cm oak frame.
You can choose between four different types of glass for all our oak frames. Acrylic glass (also called plexiglass, the most durable, light and supplied with foil) or one of the three real glasses: normal glass, non-reflective glass (more matte, which removes most of the glare) and the classy museum glass, which provides the best protection against UV rays.

Passepartout / Mat / Mount
Some posters are better framed with a passepartout, which is a 1.5 mm thick frame made of acid-free cardboard, which lies inside the frame between the glass and the picture.
For our 30x40 frames we only offer white passepartout which fits A4 (21x29.7cm) and A5 (14.8x21cm) posters, but if you have special wishes for the color or size of the passepartout, just look at our custom passepartouts. They are available in many colors, with exactly the measurements you define.
If you would like to frame a 30x40 cm poster with passepartout in a wide oak frame, the obvious choice would be a wide 40x50 oak frame or a wide 50x60 oak frame. Both can be purchased with passepartout for 30x40 posters.
