What are standard tolerances for cabinet door gap alignment and how are they achieved?

• A. Typically 1/8 to 1/4 inch around doors
• B. Typically 1/16 to 1/8 inch around doors
• C. Typically 1/32 to 1/16 inch around doors
• D. Typically 1/4 to 3/8 inch around doors

Answer: (B)

A small, even reveal around cabinet doors is essential for both appearance and function. The typical gap you aim for around doors is about 1/16 to 1/8 inch. That range balances several practical needs: it gives enough clearance so doors don’t rub as they open and close, accounts for seasonal wood movement and slight frame variation, and still looks visually tidy with a consistent line along all edges.

This is achieved by choosing hinges with good adjustment capabilities and by careful installation. Start by mounting hinges so the door sits where you want it relative to the frame, using shims or spacers to set the initial distance. Then use the hinge adjustment screws to fine-tune the door position in three dimensions—up/down, left/right, and in/out—so the gaps along the top, bottom, and sides are uniform. If needed, tweak by adding or removing shims and rechecking after the door is closed.

Other ranges would either look uneven or risk rubbing. A gap that's too small can cause binding, while a gap that's too large looks sloppy and can collect dust or catch on hardware. The 1/16–1/8 inch range is the practical compromise that quality cabinet makers aim for.
