How Many Hinges Does a Cabinet Door Need?
Short answer: most cabinet doors need two hinges. Add a third once a door gets tall or heavy. As a rule of thumb, beyond about 900mm to 1000mm in height, or where the door is made from a dense material like thick MDF or solid timber. Very tall doors, such as full-height larder or wardrobe doors, commonly take four or more. Height and weight both count and the heavier of the two decides.
Why the number matters
Hinges do two jobs: they carry the weight of the door and they hold it straight. Under-hinge a door and both jobs suffer. The symptoms are familiar, the door drops at the outer edge, the gap at the top opens up into a wedge and it starts to catch on the door beside it.
Worse, the load concentrates on the fixings. A door with too few hinges works its screws loose in the carcase side over time. Once the board around a fixing has crumbled, adjustment will not bring it back.

Treat that as a starting point rather than a rule. It assumes a normal cabinet door in a sheet material. Adjust upwards if any of the following apply:
- The door is heavy for its size — solid timber, thick MDF, or a door carrying a mirror or glass panel.
- The door is wide as well as tall. Width acts as leverage on the hinges, so a wide door is harder work than a narrow one of the same height.
- The door gets heavy use — a commercial or contract setting, or a cabinet opened dozens of times a day.
- Anything is mounted on the door, such as racks or storage on the back face.
If you are between two numbers, fit the higher one. An extra hinge costs very little next to rehanging a sagging door later.
Where should the hinges go?
The usual approach is to set the top and bottom hinges an equal distance in from each end of the door, then space any additional hinges between them. Keep the top and bottom pair symmetrical, that is what keeps the door hanging straight.
Where a door has three hinges, the middle one is doing less work than the outer two, so it does not need to be exactly central. What matters far more is that the outer pair are evenly set and that all the hinges are in line with each other, so no single hinge is being twisted.
Use the same hinge throughout
Whatever the count, fit the same hinge series on one door and ideally, across one cabinet. Different series sit at different depths and are set up with different mounting plate heights, so mixing them means the door can never be brought into line and the fronts across a run will not match.
Frequently asked questions
How many hinges does a kitchen cabinet door need?
Two for a standard base or wall unit door. A tall larder or appliance-housing door will usually want three or four, depending on height and weight.
Can I fit three hinges instead of two to carry a heavier door?
Yes and that is the right instinct, spreading the load over more hinges reduces the strain on each one and on the fixings in the carcase.
What happens if a door has too few hinges?
It sags at the outer edge, the gap at the top opens into a wedge, it catches on the neighbouring door and over time the fixings work loose in the board. Adjustment masks it briefly but will not cure it.
Do soft close hinges change how many I need?
Not directly: the count follows the size and weight of the door. Soft close does reduce the shock loading from a door being slammed, which is easier on the fixings over the life of the cabinet.
Does the middle hinge have to be exactly central?
No. Keep the top and bottom hinges symmetrical and make sure every hinge is in line with the others. The middle hinge carries less of the load, so its exact position is not critical.
Do wardrobe doors need more hinges than kitchen doors?
Usually, yes, simply because they are taller. A full-height wardrobe door will commonly take four or more.
