700 Micron White Backing Board - Frame Size A3 420 x 297mm - Pack of 5

Measure the width and height of your artwork or print — not the frame you want. The frame's internal opening (rebate) must match your print size. If your print is 30x40cm, order a 30x40cm frame. If your print is A4 (210x297mm), order an A4 frame. For prints with a white border you want to keep, measure the full print including the border. Visit our measuring guide for step-by-step instructions.

All our standard frames come complete with 2mm clear glass and backing board. Selected frames also include a pre-cut white mount. Everything you need to display your print is in the box — simply insert your artwork and hang. Check the individual product description to confirm what is included with your specific frame.

Our frames are manufactured from solid wood with hand-finished joins — not MDF or composite. Solid wood frames are more durable, lighter per unit, and more premium in appearance than MDF alternatives. They are suitable for professional framing, gallery display, and resale.

Yes — Strand Framing is a wholesale frame manufacturer. We offer volume pricing and trade accounts for photographers, photo studios, print labs, galleries, art shops, and online retailers. The more you order, the lower the unit price. Contact us to discuss trade account terms and wholesale pricing.

The mount aperture should be slightly smaller than your print — typically 5–10mm smaller on each side so the mount overlaps the edge of the print and holds it in place. For example, a 10x8" print typically uses a mount with an 8x6" aperture. Our picture mounts are available in a wide range of sizes and colours. You can also order a custom-cut mount to any size.
