What thickness blank do I need for relief carving?

The blank should be at least the relief depth plus 10-15mm for background material below the deepest point. For a 15mm medium relief, use a blank at least 30mm thick. Add 5mm if you plan to glue the panel to a backboard for clamping.

What is the best wood for relief carving?

Lime (linden) is the traditional choice for relief carving in Europe - it is soft, even-grained, and holds fine detail. Jelutong and basswood are also excellent. For harder, more durable carvings, use cherry or walnut. Avoid open-grained woods like oak for fine detail.

What is the difference between low and high relief?

Low relief (bas-relief) has a depth of 10mm or less with forms barely projecting from the background. Medium relief is 10-25mm with clearly defined forms. High relief (alto-relief) is 25mm+ where figures may be nearly fully rounded and undercut.

Should I add a border around my relief carving?

A border of 15-25mm around the carving provides a visual frame and gives you material to clamp to during carving. The border can be left flat, moulded, or carved with a decorative edge. Always start with a blank larger than the final design.

How We Calculate This

This calculator determines the blank dimensions needed for a relief carving panel.

Blank sizing

Blank thickness = Relief depth + 10mm background + 5mm waste

Blank size = Panel dimensions + 40mm (20mm border each side)

Volume estimate

The volume of wood to remove is estimated as a percentage of the total relief area: low relief ~40%, medium ~60%, high ~75%.
