Calculate the mat border and the resulting frame size for a piece of art.
| Artwork size | 8 × 10 in |
|---|---|
| Required frame (outer) size | 12 × 14 in (30.48 × 35.56 cm) |
frame size = artwork size + (2 × mat border) on each dimension. A uniform border on all four sides is assumed.
The mat border width is added to every edge of the artwork size, so the outer frame size is the artwork size plus twice the border width in each dimension.
