Frame size guide

A5 frame

A A5 frame has an opening of 148 × 210 mm (5.83 × 8.27 inches). A small frame suited to studies, cards and postcard-style drawings.

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.

BorderAperture (mm)Aperture (in)Sheet needed (mm)
30 mm (1.18 in)88 × 1503.46 × 5.91100 × 162
40 mm (1.57 in)68 × 1302.68 × 5.1280 × 142

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

A5 paper (see the A5 guide) matches this frame unmounted. For a mounted drawing, use a smaller sheet as below.

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.
