A face frame is a frame of solid timber or MDF, typically 38–50 mm wide, fixed across the front edges of the carcass. Doors either overlay the frame or sit inset inside it. It is the traditional North American method; frameless cabinets have no frame at all.
What the frame actually does
The frame is not decoration. It stiffens the front of the box, hides the carcass edge and gives the doors a consistent surface to close against. On a run of cabinets it also carries the joints between units, so a row of framed cabinets reads as one piece rather than a series of boxes.
The cost is space. The frame occupies the front of every opening, so the clear opening of a 600 mm cabinet drops to roughly 500–520 mm with a 38 mm frame. On drawers this is more noticeable than on doors, because the drawer box has to pass through the opening.
| Frame width | Clear opening | Typical use |
|---|---|---|
| 32 mm | 536 mm | Compact and bathroom units |
| 38 mm | 524 mm | Standard residential |
| 50 mm | 500 mm | Heritage profiles, heavy mouldings |
Inset or overlay on a framed cabinet
Both exist, and they are not interchangeable. An overlay door covers the frame from the front — cheaper, more forgiving, and the usual choice for volume work. An inset door sits inside the frame opening, flush with the face, and needs a frame that is machined accurately and hinges that allow adjustment in two planes.
Inset is what most people mean when they say "traditional kitchen", but it is a specification decision with a cost: roughly 15–25% more on door cost and a longer installation, because every gap has to be set.
Where a face frame makes sense
Framed cabinets suit renovation work in older buildings, where wall lines are not straight and a frame gives the installer something to scribe to. They also suit narrow units — a 300 mm framed cabinet looks more substantial than a frameless one of the same width.
They are a poor fit for full-height handleless runs, where the frame interrupts the door line, and for projects where every millimetre of internal width matters.
Frequently asked questions
Is a face frame cabinet stronger than a frameless one?
Not inherently. The frame adds stiffness to the front edge, but a well-built 18 mm frameless carcass with a proper back panel is stiffer overall than a thin framed box. Strength comes from board thickness, joint method and back panel, not from the frame alone.
Can I mix framed and frameless cabinets in one kitchen?
Physically yes, visually no. The door plane sits at a different depth, so the two runs will not line up unless you use fillers and a deeper framed cabinet. Decide per room, not per wall.
Does a face frame reduce storage?
It reduces the clear opening, not the internal volume. You lose roughly 25–50 mm of access width per opening, which matters most on drawers and pull-outs.
What frame width should I specify?
38 mm is the safe default for residential work. Go to 50 mm only if the design calls for a heavier moulding profile, and check that appliance openings still clear.
