Good to know
Art business glossaryWhy the window is smaller
The mat has to hold the artwork, so the window is cut a little inside its edges — about 5 mm a side. To show the whole sheet, deckled edges and all, float it: overlap 0, mounted on the board behind.
A deeper bottom border
With equal borders a framed piece looks as if it is slipping down. A bottom border about 1 cm deeper than the top looks centred — framers call it weighting.
Use archival board
Acid-free or museum board will not yellow or mark the work over the years. Behind the glass, it is the part that touches the artwork.
