Frame size guide
A2 frame
A A2 frame has an opening of 420 × 594 mm (16.54 × 23.39 inches). A large frame with real wall presence, suited to ambitious portraits and statement pieces.
Mount aperture by border width
The wider the border, the smaller the visible image. All figures assume the mount overlaps the drawing sheet by 6 mm on every side.
| Border | Aperture (mm) | Aperture (in) | Sheet needed (mm) |
|---|---|---|---|
| 30 mm (1.18 in) | 360 × 534 | 14.17 × 21.02 | 372 × 546 |
| 40 mm (1.57 in) | 340 × 514 | 13.39 × 20.24 | 352 × 526 |
| 50 mm (1.97 in) | 320 × 494 | 12.6 × 19.45 | 332 × 506 |
| 60 mm (2.36 in) | 300 × 474 | 11.81 × 18.66 | 312 × 486 |
| 70 mm (2.76 in) | 280 × 454 | 11.02 × 17.87 | 292 × 466 |
Many artists add a slightly deeper bottom border, around 10 to 20 percent more than the top and sides, so the picture sits comfortably. Use the frame and mount calculator to work it out with your own numbers.
Paper sizes that fit
A2 paper (see the A2 guide) matches this frame unmounted. For a mounted drawing, use a smaller sheet as below.
| Border | Standard paper sizes that work behind the mount |
|---|---|
| 30 mm | No standard size fits exactly - cut a custom sheet of 372 × 546 mm |
| 40 mm | No standard size fits exactly - cut a custom sheet of 352 × 526 mm |
| 50 mm | 16 × 20 inch |
| 60 mm | 16 × 20 inch |
| 70 mm | 16 × 20 inch |
Framing tips
- Measure your actual frame before cutting a mount - sizes vary slightly between makers.
- Use acid-free mount board and a spacer so the drawing never touches the glass.
- Consider UV-filtering glazing for work on paper that will hang in daylight.
