Kitchen Cabinet Sizes Guide: How to Plan the Right Units
1 min reading time
A practical guide to planning kitchen cabinet sizes, appliance spaces, corners and cabinet combinations before ordering.
Getting kitchen cabinet sizes right is one of the most important parts of planning a new kitchen. The aim is not to fill every millimetre with cupboards; it is to create a layout that fits the room, appliances, doors, windows and services while leaving sensible working space.
Start with the room, not the cabinets
Measure the full wall lengths first, then mark anything that cannot easily move: doors, windows, boilers, soil pipes, water supplies, sockets and appliance connections. This gives you the real space available for cabinets.
Think in cabinet groups
Most kitchens combine several cabinet types. Base units form the main worktop run, wall units add storage above, and specialist units such as sink units, oven units and corner units solve specific layout requirements.
Allow for appliances and fillers
Do not assume every wall can be filled edge to edge with cabinets. Appliances need their own space and door swing, walls are not always perfectly square, and finishing panels or small allowances can help the final run look cleaner.
Use a planner before ordering
The easiest way to compare cabinet combinations is to build the room digitally first. The JD Greta Free Kitchen Planner lets you test different layouts before committing to an order.
Common planning mistakes
- Measuring only one point on a wall
- Forgetting door and window openings
- Ignoring appliance clearances
- Planning a corner without checking door access
- Leaving no space for panels, plinths or finishing adjustments
- Ordering before confirming the complete cabinet list
What to do next
Measure carefully, create the room in the planner, then compare the units required with the relevant JD Greta collections. If a measurement or cabinet choice is unclear, contact us before ordering.
