Fit the drawer box and its runners before sizing the visible inset front. A front cannot maintain an even reveal if the drawer moves sideways, drops when opened or stops at a different depth each time. Once the mechanism repeats reliably, fit the front to the actual opening and use measured spacers to hold the intended gaps.
The reveal is not the runner clearance
A reveal is the visible gap around the front. Runner clearance is the space required by the slide system around or under the drawer box. They are separate dimensions. Blum’s MOVENTO construction guidance, for example, uses specific box dimensions and bottom details. Those are instructions for that system, not a universal subtraction for all drawers. Keep the exact runner model beside the cutting list.
A wood-on-wood drawer is another case. Its side clearance, seasonal movement and running surfaces need their own fitting plan. Do not build that box to a metal-slide specification. Likewise, do not reduce a metal-slide drawer because a video about traditional drawers suggests a different gap.
Measure the opening after assembly
Record width at top and bottom and height at left and right. Check diagonals before cutting a tapered front. If the cabinet is intended to be rectangular but is racked, correct it first. Label each front with its opening number, top edge and show face. In a bank of drawers, one millimeter moved from one gap often appears in the next, so plan the whole stack before fitting the first piece.
For an illustrative 500 by 180 mm rectangular opening with a chosen 2 mm gap at every edge, the front is 496 by 176 mm. That is simple subtraction, not a recommended universal reveal. A wide solid-wood front may need more movement allowance across its grain; paint and edge profiles also influence the final appearance. Use the hardware instructions and expected movement to decide the gaps before substituting numbers.
| What you see | Check before removing wood |
|---|---|
| Both side gaps taper in opposite directions | Case square and front square |
| Front is even when closed but drops on opening | Drawer box or slide engagement |
| One edge stands proud | Depth adjustment, bumper and slide mounting |
| Gap changes after several open-close cycles | Loose fasteners, box racking or slipping front attachment |
Fit in an order you can retrace
Make the first fitting with the front slightly oversize where trimming is planned. Establish a straight lower edge and a square end, then fit the width and finally the height. Keep notes showing which edge you trimmed and by how much. If you remove material from both opposite edges without a reference, the center of the front drifts and grain alignment across a stack becomes harder to control.
Use a sharp hand plane or another controlled trimming method suited to the material. A veneered front needs special care at the edges; its show veneer may be extremely thin. Do not sand a localized lump into the middle of an edge while trying to increase the entire gap. Check frequently under the same light, with the front held at its actual closing depth.
Hold position without guessing
Use firm spacers of measured thickness at the edges. Business cards vary; they are convenient packing material, not a universal gauge. Keep the bottom support in place while locating the front. Any temporary adhesive must be compatible with the finish and must not be the only support for a heavy front. A dry fitting with clamps and the drawer removed can be easier to control than trying to reach through a tiny gap.
Choose attachment holes and screws that allow the planned adjustment without protruding through the show face. Check thickness at the actual screw location, particularly behind a routed profile or recessed panel. Follow the slide or front-fixing hardware instructions, and support the front while loosening fasteners. Tighten gradually and recheck the gap, because tightening can pull a poorly seated front sideways.
Check the finished action
Operate the drawer repeatedly, then check with its intended load. Adjust one direction at a time. On systems that provide side, height, tilt and depth adjustments, learn which control moves which part before turning all of them. Finish thickness may consume part of a very small reveal; allow for that when fitting bare parts.
Write down the final gap and drawer location before removing fronts for finishing. Reinstall them in the same openings with the same reference marks. That small record is more useful than trying to remember which nearly identical front had a slightly wider lower edge.
Size two equal inset fronts
Formula: (opening − 2 × outside gap − centre gap) ÷ 2. Example: 600 opening, 2 on each outside and 2 in the centre gives two 297-wide fronts. Gaps are your design inputs; check hardware requirements and seasonal movement.
