How deep should an inlay recess be?

Rout the recess to the inlay thickness plus a small allowance for the glue line (~0.2mm) and a sanding margin (~0.1mm) — this calculator adds 0.3mm by default, so a 1.5mm inlay gives a 1.8mm recess. The inlay then sits very slightly proud and is sanded flush after the glue has cured. True sawn veneer is around 0.6mm thick; constructional/thick veneer runs 1-2mm, and solid-wood inlays 3-6mm. A router with a depth stop ensures a consistent recess depth.

What tools do I need for inlay work?

A small router or Dremel with a straight bit for recesses, a sharp craft knife for marking lines, and a chisel for cleaning up corners. For fine line inlays, a scratch stock or inlay routing kit is invaluable.

What glue should I use for inlays?

PVA or hide glue works well for most inlays. Apply glue to the recess, press the inlay in, and clamp with a flat caul. For very thin veneers, contact adhesive or iron-on veneer methods work well.

How We Calculate This

This calculator determines the recess dimensions and inlay material needed for decorative inlay work.

Shapes supported

Rectangle: Area = length x width.

Circle/Oval: Area = pi x (length/2) x (width/2).

Border / Banding: Calculates the frame (recess) area around a panel as outer area minus inner area, and the banding length as the channel centreline 2 x (length + width) - 4 x border width (mitred corners shorten the run).
