A frame can be seen as the bridge between the poster and the home. The picture frame must therefore both suit the poster and also fit into the decor you have in your home. Depending on which frame you choose, the poster will change its expression.
My art is very detailed with soft transitions. So, based on the art poster, I would recommend a narrow frame. If it is a wooden frame, I love that you can see the grain in the wood, so the frame has a natural look (some wooden frames are painted to look like plastic). Right now, metal frames are also popular. The advantage of them is that in the large sizes they can be narrower and still be stable. A matte black metal frame can give a nice raw look, where a gold frame can, for example, make the expression more feminine. At home, for example, I have framed the art poster "Rose Rock" with a narrow gold frame.
Once you have decided on a frame, you also need to decide on glass.
You can choose a replacement frame with a completely regular glass, but if the poster is going to hang in a place where there is a lot of glare, it may be an advantage to choose a non-reflective glass. This means that you can still see the motif in the sun, while the glass also protects against UV rays, thus giving the poster a longer lifespan.
If you want a wooden frame with regular glass, I can recommend the frames from Trævarefabrikkernes Udsalg. The Nordic Line series is also really nice. It is available in many stores.
