The drawer box is the structural drawer behind the cabinet face — four walls, a floor, a back panel. It's the part that holds the contents and sets the dimensions any drawer organiser has to fit. The box is usually 2–4 cm narrower than the cabinet face; the cabinet face overhangs to close the cabinet aesthetically.
Why the box, not the face
Three structural reasons the drawer box is the only dimension that matters for organiser fit:
- The cabinet face overhangs. The face is decorative; the box is functional. An organiser sized to the face won't fit the box.
- Runners take more from the box than from the face. See runner clearance.
- Adjacent boxes can share a face. A wide cabinet face sometimes hides two narrower drawer boxes — one box per face is the default but not the rule.
What the box's dimensions are called
- Internal width. Wall to wall along the box's short axis. See drawer width.
- Internal length. Front to back along the box's long axis. See drawer length.
- Internal depth. Floor to roof. See drawer depth.
How to identify the box edges
Open the drawer fully. The box's walls are the inner surface that touches contents. The cabinet face sits in front of the box, often with a small gap. The runners sit between the box's outer walls and the cabinet's inner walls.
Measure inside the box, wall to wall, every time. The drawer builder always asks for box-internal dimensions.
