Measure inside the frame
Match the matboard size to the usable internal space, not the frame's outside edge.
Visible opening and overlap
The opening shows the image while a small overlap supports the print behind it.
Single or double matboard
Choose one matboard colour or add a narrow contrasting inner layer.
T002 - Portrait triptych (side by side)
A ready-made collage matboard for a frame you already own
Three equal portrait openings arranged side by side, with multiple print sizes.
Choose the layout size that matches the usable space inside your frame, then select the top matboard colour and an optional second layer. Leave the frame unselected for a loose matboard you can assemble at home.
Designed for an existing frame
Plan the matboard around the frame you already own
Measure the usable internal space inside your frame, then decide which photos belong together. The outside matboard size controls the fit; each opening size controls how much of its photograph remains visible.
