Mat borders are acid-free matboard mounts that sit just over the edges of an image, keeping them in place with a neat bevel.

We have a range of stock mats to suit the frame sizes in our sale, available with select window sizes in mid-tone white only.

Frame Size 8x10” → Window Size = 4x6”, 5x7” or 6x8”

Frame Size 10x12” → Window Size = 5x7”, 6x8” or 8x10”

Frame Size 10x13” → Window Size = 5x7” or 8x10”

Frame Size 12x16” → Window Size = A4/8x12”

Frame Size 14x18” → Window Size = 11x14”

Frame Size 16x20” → Window Size = A3/12x16”

Frame Size A3 → Window Size = A4

Frame Size A2 → Window Size = A3

Please note, window sizes are slightly smaller than the sizes mentioned above in order to cover the edges of your framed image.

If you require a custom mat, this can be arranged in our shop after lockdown, when COVID-normal trading can recommence.
