What are United Inches?
United Inches is a unit of measure used to determine costs of certain framing materials such as moulding. Calculating united inches is simple. It is the width plus the height of the unframed combination. An unmatted 8×10 image would have 18 united inches. An 8×10 image with a three inch mat border would have 30 united inches. The maximum size for a piece to be framed is 84 united inches (image and mat). We will give you an estimated final framed size of your piece in the Details as Shown section when you are selecting your item.
