An ideal size to fit most walls

These frames will fit artwork equal to the standard A3 paper size. Halfway between A4 and A2 - this popular option makes for an eye-catching display while not becoming overwhelming. We love seeing them hang landscapes or portraits above sofas or in hallways. Each is available with either high-quality clarity+ acrylic or glass (our glazing guide can be found here), and you can always add a mount. If you need something bigger, our A3+ size frames might be what you need.

If you're keen to learn more about our "A" size frames, we have a handy "A" paper size guide that's all about framing standard paper sizes.
