The height of a cabinet's legs looks like a minor detail, but it decides three things at once: the gap under the cabinet that the kickboard covers, the height the worktop ends up at, and how much uneven floor the legs can level out. Get the height right, and the cabinet sits at the right working height, the plinth lines up, and the leveling has room to work. Get it wrong, and the worktop is too high or too low, the kickboard will not fit, or the legs run out of adjustment on a floor that is not quite level.
This guide covers cabinet legs height: the standard dimensions, how the adjustment range works, and how to choose the right height for the cabinet. Based on 15 years of manufacturing cabinet legs for makers across 40+ countries.

What Cabinet Leg Height Controls
Three Jobs in One Dimension
The height of a cabinet leg is not arbitrary — it sets three functional outcomes that all matter.
| What Height Controls | Why It Matters |
| Plinth gap | The space the kickboard must cover |
| Worktop height | The ergonomic working height |
| Leveling range | How much uneven floor can be corrected |
The plinth gap is the kickboard's space. The leg height, plus the cabinet base, sets the gap between the cabinet and the floor — and the kickboard must fill that gap exactly. A leg height that does not match the planned plinth means a kickboard that will not fit, or a gap that shows.
Worktop height is ergonomics. The leg height is part of the total height of the cabinet, which determines where the worktop ends up. Standard kitchen worktop height is around 900mm, and the legs contribute to reaching that — a leg that is too tall or short pushes the worktop out of its comfortable working range.
The adjustment range is the leveling reserve. Beyond the base height, an adjustable leg extends to correct an uneven floor. The adjustment range is additional height on top of the minimum, and it must be enough to cover the floor's unevenness.
Cabinet legs and height explained
Standard Heights
The Dimensions That Cover Most Cabinets
Most cabinets are served by standard leg heights, and matching those keeps things simple and economical.
| Cabinet Type | Typical Leg Height | Total Plinth Gap | Notes |
| Kitchen base unit | 100-150mm | 100-150mm | Standard plinth height |
| Bedroom wardrobe | 80-120mm | 80-120mm | Lower, heavier load |
| Bathroom vanity | 100-150mm | 100-150mm | Match the plinth |
| Tall pantry unit | 100-150mm | 100-150mm | Same plinth, more load |
| Floating / wall look | 150-300mm | 150-300mm | Higher legs for a lighter look |
The kitchen standard is 100-150mm. Most kitchen base units use a leg height that produces a 100-150mm plinth gap, matched to a standard 150mm kickboard. This is the dimension the entire kitchen is designed around, and it is where the vast majority of cabinets land.
Bedroom and vanity follow the plinth. A wardrobe or bathroom vanity uses a leg height that matches its own plinth — often slightly lower than a kitchen, but the principle is the same: the leg height and the plinth gap must agree.
Higher legs change the look. A leg of 150-300mm lifts the cabinet higher, creating a more open, floating look and easier cleaning underneath — but it also raises the worktop and changes the proportions. It is a design choice as much as a functional one.
The Adjustment Range
Height Beyond the Minimum
An adjustable leg adds a range of height on top of its base height, and that range is what levels the cabinet on an uneven floor.
| Floor Condition | Recommended Adjustment Range | Why |
| Level floor (new build) | 10mm | Minor correction only |
| Slight unevenness (<5mm) | 10-15mm | Standard range |
| Moderate unevenness (5-15mm) | 20-30mm | More correction needed |
| Severe unevenness (>15mm) | 30-50mm | Maximum correction |
The range is height above the minimum. A leg listed as 100-120mm has a minimum height of 100mm and can extend 20mm to 120mm. The cabinet must be designed for the minimum, with the range as reserve for leveling — never the reverse.
Match the range to the floor. A nearly level floor needs only a small range; an older, more uneven floor needs a larger one. A leg with too little range runs out of travel before the cabinet is level, forcing shims; too much range is fine but unnecessary.
The range is spent, not saved. Each corner of the cabinet uses however much of its range the floor requires, and different corners use different amounts. The total available range must cover the floor's worst unevenness, not its average.

Choosing the Right Height
Matching the Leg to the Cabinet
| Requirement | Dimension to Match | The Rule |
| Planned plinth / kickboard | Leg height | Match the leg to the plinth gap |
| Worktop height target | Total cabinet height | Leg is part of the total |
| Floor unevenness | Adjustment range | Range must cover the floor |
| Load | Leg diameter | Heavier cabinet, larger leg |
Match the leg to the plinth first. The plinth gap is the hard constraint — the kickboard is a fixed size, and the leg height must produce exactly that gap. Start from the plinth, and the leg height follows.
Check the worktop height. The leg height, plus the cabinet body, should land the worktop at the intended height — around 900mm for a kitchen. If the math does not work out, adjust the leg or the cabinet body, not the intended worktop height.
Size the leg for the load and the floor. A taller, heavier cabinet needs a larger-diameter leg to carry the load, and an uneven floor needs enough adjustment range to level it. The height is the visible dimension, but the diameter and range are the ones that do the work.
Common Mistakes
The Errors That Choose the Wrong Height
| Mistake | Consequence | The Fix |
| Leg height not matching the plinth | Kickboard will not fit | Match leg to plinth gap |
| Wrong worktop height | Uncomfortable working height | Check the total cabinet height |
| Insufficient adjustment range | Cannot level the floor | Match range to floor unevenness |
| Designing at maximum extension | No reserve for leveling | Design for minimum, use range as reserve |
| Leg too small for the load | Buckled or stripped leg | Size diameter to the load |
The unifying lesson: cabinet leg height is a dimension with three jobs — plinth, worktop, and leveling — and each must be checked. Match the leg to the plinth gap, confirm the worktop height, and ensure the adjustment range covers the floor. Get all three, and the cabinet sits at the right height, with a fitting kickboard, and levels out cleanly.
Conclusion
Cabinet leg height is a small dimension with an outsized effect — it sets the plinth gap the kickboard fills, the worktop height the user works at, and the leveling range that corrects the floor. Standard heights serve most cabinets; the choice is about matching the leg to the plinth, confirming the worktop, and ensuring enough range for the floor. Choose the height deliberately, and the cabinet sits right, levels cleanly, and looks the way it was designed to.
Key takeaways:
At Shaxi Hardware, every cabinet leg ships with documented height, adjustment range, diameter, load rating, and material, matched to the cabinet and the floor. Our ISO 9001 certified facility manufactures standard and custom heights, and our technical team helps specify the right leg for the plinth, the worktop, and the floor. Because the right leg height is the one that makes all three line up.
