Cabinet depth is a small detail that shapes comfort throughout your home, from reaching for things and walking past to your budget. Too deep or too shallow, and doors clash, walkways feel tight, or things simply don't fit.

The easy rule: 30 / 45 / 60 cm

Use it as a starting point, then adjust for your actual appliances and space. This article sums up the key dimensions so you can decide without guessing.

30 cm suits bookshelves, display shelving and hallway consoles: it keeps walkways clear and shows everything at a glance.
45 cm works for folded-clothes shelves, kitchen wall cabinets and dressing tables: items sit across the full shelf and are easy to reach.
60 cm is the standard for kitchen base cabinets, serious work desks and hanging wardrobes, with room for full-extension drawer runners, sinks and hobs, and coat hangers without catching the doors.

Don't forget the clearances

Keep at least 90 cm of walkway in front of furniture so doors can open fully. In L-shaped kitchens, check that doors don't collide at the corner, and consider corner hinges or corner drawers. In small spaces, go shallower and use grip channels or slim handles to keep the room visually open.

Shallow = open and quick to reach
Medium = all-purpose
Deep = more storage and room for hardware

Before you lock in the spec, confirm depths against your actual appliance list, and check walls, skirting, door frames and the positions of water and power points. With complete information, your cabinets fit from day one, work smoothly, stay on budget and look exactly as intended.
