Gap = Base (1/16in) + Material Adjustment + Humidity Adjustment; Kitchen/Bathroom use 3/32in minimum; Solid wood add seasonal
Example: 30x18in MDF door, partial overlay 1/2in, kitchen, European: Side gaps = 3/32in (2.4mm); Top = 1.2mm; Bottom = 1.5mm; Screws = 2 (#8 x 1-1/4in); Pilot = 3/32in

What is the standard gap around cabinet doors?

Standard gaps: 1/16" (1.5mm) on all sides is typical. Slightly larger on bottom (3/32" or 2.5mm) for clearance. Full overlay doors have the gap at the frame edge; inset doors have consistent gaps around. Standard reveal is 1/32"-1/16" (0.8-1.5mm). Adjust for humidity in kitchens/bathrooms - use 3/32" (2.5mm) or more.

How many hinges do I need for cabinet doors?

General rules: Doors under 24" tall: 2 hinges. Doors 24-36": 2 hinges (quality). Doors 36-48": 3 hinges. Doors over 48" tall: 4 hinges. Also: Use more for heavy doors (glass, solid wood), heavy-use cabinets, or older users. More hinges = less sag and more secure.

Should cabinets in bathrooms have larger gaps?

Yes, bathrooms (andlaundry rooms) need bigger gaps: Use 3/32" (2.5mm) instead of 1/16" (1.5mm). Wood and MDF expand with humidity - 3-5% seasonally. Large doors with small gaps can stick or crack. Leave at least 1/8" (3mm) for solid wood bathroom cabinets. Use ventilating doors or paint back of doors.

What's the difference between overlay and inset cabinets?

Overlay: Door sits on top of frame, partially covering it. Partial overlay 1/2" typical, full 1-1/4". Easier install, more gap tolerance. Inset/Flush: Door sits inside frame, gaps visible. More precise needed, more traditional look. Frameless/European: No face frame, doors inset to edge, needs precise gaps for alignment. Each needs different hinge type and mounting.

How do I adjust cabinet door gaps?

Most modern hinges have adjustment: Side (lateral): Move door left/right. Depth (in/out): Tighten/loosen gap. Height (up/down): Adjust at hinge. Use a putty knife or screwdriver. Make small adjustments, test between each turn. For stuck doors in humidity, use a heat gun briefly or wait for dry weather. Never force doors closed.
