How to Measure Cabinet Depth
Depth is the measurement most people skip when they shop for cabinets, and it is the one that causes the most problems after installation. A cabinet that is an inch too deep can block a door from swinging fully open, crowd a walkway, or stick out past the end of a run. Getting depth right before you order is a lot cheaper than returning cabinets after they arrive.
Standard cabinet depths
- Base cabinets: 24 inches, measured to the cabinet box, not the countertop overhang
- Wall cabinets: 12 to 13 inches, shallower so they clear your head and the countertop below
- Tall and pantry cabinets: 24 inches, usually matching base cabinet depth
- Vanity cabinets: 21 inches, slightly shallower to fit smaller bathrooms
How to measure your space
- Measure the existing cabinet box, not the countertop, since countertops usually overhang by an inch or more.
- Measure from the wall itself, not from trim or baseboard, which can add a quarter inch or more.
- Check for obstacles in the depth of the run, like outlets, window sills, radiators, and vents.
- Confirm clearance for open doors and extended drawers, not just the closed box.
- Measure at more than one point along the wall and use the smallest number, since walls are rarely perfectly straight.
Mistakes worth avoiding
The most common mistake is assuming every base cabinet is 24 inches deep. That is true for most lines, but some manufacturers sell 23 inch or 25 inch options, and those inches matter when fitting an appliance next to the cabinet. The second most common mistake is forgetting that wall cabinets and base cabinets use different standard depths, which can make a wall cabinet hang much further into the room than expected.
Once you know the depth your space needs, you can search BeeBoard by exact depth alongside width and height, since depth is a filter most retailer sites do not expose on their own search pages — the link above starts at the standard 24" base depth, adjustable to whatever your own measurement comes out to.
