Are Kitchen Cabinet Doors Standard Sizes?
If you’re replacing your kitchen cabinet doors, one of the first questions you’ll probably ask is “Are kitchen cabinet doors standard sizes?”
The short answer is yes – most UK kitchen cabinets are built to standard dimensions,
Which means replacement kitchen doors are available in a range of standard sizes. However, there are some important rules and exceptions that you need to understand before ordering. In this guide, we’ll explain how standard kitchen cabinet door sizes are calculated and show you
an easy way to work out the correct size for your cabinets.
Standard UK Base Cabinet Height
The standard height of a UK base kitchen cabinet is 720mm.
However, the cabinet door isn’t the same height as the cabinet itself.
The industry standard is to subtract 5mm from the overall cabinet height to allow for the necessary gaps and smooth operation of the doors.
Formula:
Cabinet Height – 5mm = Door Height
For example:
Cabinet height: 720mm
Minus clearance: 5mm
Standard door height: 715mm
This is why 715mm is the most common height for standard UK base cabinet doors.
How Standard Door Widths Are Calculated
Door widths follow a similar principle.
Rather than matching the cabinet width exactly, the standard calculation is:
Cabinet Width – 4mm = Door Width
This 4mm allowance provides the clearance required between doors and neighbouring cabinets.
Most cabinet widths increase in 100mm increments, although there are a couple of common exceptions.
The most common standard replacement kitchen door widths are:
| Cabinet Width | Standard Door Width |
|---|---|
| 150mm | 146mm |
| 300mm | 296mm |
| 400mm | 396mm |
| 450mm | 446mm |
| 500mm | 496mm |
| 600mm | 596mm |
These sizes are used by many UK kitchen manufacturers, making it much easier to replace worn or outdated cabinet doors without replacing the entire kitchen.
Visual Guide to Standard Door Sizes
The door configuration guide below shows how standard kitchen cabinet doors are sized across a range of base units, wall units and tall units. You can use it as a helpful reference when identifying the correct replacement door for your cabinet.
As you’ll notice, the majority of doors follow the standard sizing rules described above, while specialist cabinets such as corner units, appliance housings and curved units often require different door sizes.
Are All Kitchen Cabinet Doors Standard?
Not always.
While the vast majority of modern UK kitchens use standard cabinet sizes, there are some exceptions, including:
- Bespoke or handmade kitchens
- Older kitchens built before modern standardisation
- Appliance housing doors
- Corner cabinets
- Curved doors
- Extra-wide feature units
For this reason, it’s always worth measuring your existing cabinet or door before placing an order.
The Best Way to Measure Replacement Kitchen Doors
If you’re measuring from the cabinet:
- Measure the overall cabinet height.
- Measure the overall cabinet width.
- Apply the standard formulas:
- Height = Cabinet height – 5mm
- Width = Cabinet width – 4mm
If you’re replacing existing doors, the easiest method is simply to measure the current door, provided you’re confident it fits correctly.
Need Help Finding the Right Door Size?
Choosing the correct replacement kitchen door doesn’t need to be complicated.
If your kitchen uses standard UK cabinet sizes, there’s a good chance your doors will match one of the common sizes listed above.If you’re unsure, our team can help you identify the correct size before you order, ensuring your new replacement kitchen doors fit perfectly the first time.

Measure Door Height
Measure from top to bottom. Always measure the back of the door to ensure accuracy, as the front details or bevels can skew the size. Record the exact height in millimetres.

Measure Door Width
Measure from side to side. Place your tape measure across the flat back surface of the door. Measure from the left edge to the right edge and record the width.

Top Hinge Position
Measure from the top down. Measure from the very top edge of the door down to the centre of the top hinge hole. This ensures your new door will align perfectly with your existing cabinet.

Bottom Hinge Position
Measure from the bottom up. Measure from the very bottom edge of the door up to the centre of the bottom hinge hole. Note if your door is left or right hanging based on which way it opens.
