No need to settle for the nearest standard size

Custom Rectangle Frame Sizing

Art and objects rarely follow retail frame sizes. Custom sizing lets the frame respond to the exact piece, desired mat border, available wall space, and orientation.

Design considerations

Three dimensions to keep distinct

Item size

The exact width and height of the photograph, art, poster, mirror, or other piece being framed.

Opening size

The visible area inside the mat or frame lip. It is typically slightly smaller where overlap is needed.

Outside size

The full wall footprint, determined by opening, mat width, moulding width, and construction.

Framing in practice

Work from three connected rectangles

Practical example

A metric print intended for an existing wall niche can be sized from the artwork outward, adjusting the mat and profile until the complete frame stays within the available opening.

The item size describes the piece itself. The opening size describes what remains visible after any mat or frame overlap. The outside size describes the complete wall footprint. Changing a mat border or frame profile changes the outside size even when the artwork stays the same.

Exact sizing is useful for metric paper, panoramic crops, handmade edges, and spaces with firm width or height limits. Measurements should be recorded without rounding so fit and overlap can be discussed accurately.
