Whilst we don't offer a framing service we can give some good tips when it comes to framing your new prints:
Buying from the high street
In the UK "A" paper sizes are a standard size, see this page on paper sizes for the exact dimensions. You should be able to find standard frames on the high street for A paper sizes, although you may be restricted to simple white or black frames and they may not be the best quality or designed to last long-term.
Supporting local framers
We would always recommend talking to a local framer and supporting a local small business. The framers we know are professionals who can advise on how thick you might want your frame, whether you need a mount (or matt for our customers outside of the UK) and how thick this should be to complement the print and frame. The mount and frame can usually be customised in terms of colours too and of course you could go with a natural wood colour of which there are lots of options. If you've seen something you like, for example a frame on one of our web pages, why not screenshot the image and send to your framer to replicate.
Think about the size of the space you wish to fill. If it's a large space and you've bought a smaller print you can fill more space with a wide mount and a chunky frame. If it's a small space, no mount and a thin frame may suit you better. Bear in mind the weight of the glass too, your framer may insist on a chunkier frame if it's a large print which needs more support.
It's also worth noting all our prints include a small white border with the design inset inside this, so you can choose not to include a mount as the print will look good in a frame without one - this can also make framing a bit cheaper. We personally think a mount adds a bit more style though.
If you have bought a frame and the print needs trimming down slightly to fit in, make sure you measure very carefully, draw on guides of where to cut with a pencil and take it slow. You can't add paper back on if you cut too much off!
Our prints are delicate so do make sure you handle them carefully. Giclée prints are printed with a very fine spray of ink over the paper surface, so throughout the framing process do not touch the surface of the print at all. You could easily scratch or scuff the design.
