Cabinet Door Overlay Calculator

Our cabinet door overlay calculator helps you determine exact door dimensions for frameless (European-style) cabinets. Getting door sizes right is critical - even small errors become obvious when doors don't align or gaps are uneven. This tool calculates both full overlay and inset door dimensions.

The calculator accounts for the overlay amount (how much the door covers the cabinet box), the reveal between adjacent doors, and the hinge specifications. Full overlay doors typically cover all but 1/8" of the cabinet edge, while inset doors sit flush within the opening requiring precise gaps for clearance.

This tool is perfect for DIY cabinet builders, kitchen renovators calculating replacement door sizes, and anyone asking "what size cabinet door do I need?" or "how do I calculate cabinet door overlay?" Accurate door sizing ensures professional-looking results with consistent gaps and alignment.
