Quick answer
Cabinet leveler legs installation starts with the finished cabinet height and the floor’s highest point. Establish one level reference, choose legs that cover the required setting at every support position, then adjust each cabinet before joining and anchoring the run.
Do not set every foot to the same extension on an uneven floor. The cabinet tops should line up; the leg settings underneath may differ. Plan the toe kick after the support layout, not as a substitute for it.
What cabinet leveling legs actually do
Adjustable cabinet legs provide support and let you change the height at individual points beneath a cabinet. Kitchen cabinet leveling feet are useful when the floor varies along a run or from the front of a cabinet to the back.
They do not straighten a damaged cabinet, replace required anchoring, or make the cabinet waterproof. The visible toe-kick panel covers the base; the legs and cabinet structure carry the load.
Before drilling: this guide explains the planning and installation sequence. Use the instructions for your actual leg set and cabinet construction for mounting positions, fasteners, load limits and anchoring. Cabinets with an existing structural toe-kick base are not automatically suitable for a leg conversion.
Plan the finished height before choosing legs
Start with the required countertop elevation, the cabinet body height and the complete countertop build-up. Include any specified underlayment or support layer above the box. A cabinet leg’s catalog height is not the same thing as finished counter height.
Use dimensions measured from the same reference. Then check how the leg’s mounting plate or socket contributes to its installed height. Do not add a mounting-plate allowance twice if it is already included in the published measurement.
| Part of the assembly | Example dimension | What it includes |
|---|---|---|
| Finished counter height | 36 in | Measured above the chosen finished-floor reference. |
| Cabinet body | 30.5 in | Body only, excluding the legs and countertop. |
| Countertop build-up | 1.5 in | The complete specified assembly above the cabinet. |
| Space below the body | 4 in / 101.6 mm | The resulting gap; verify its relationship to the leg’s listed adjustment height. |
If the finished floor drops farther along the run, the gap below a level cabinet grows. Check that location before deciding that a leg with a 4-inch setting will fit the entire installation.
Use the Cabinet Box Estimator to plan sheet quantities for cabinet bodies. Keep the leg-height and support calculations separate from the material estimate.
Find the floor’s high point across the full run
Use a level laser line and measure vertically down to the floor at the planned front and rear support locations. The shortest distance from that fixed line identifies the highest measured floor point. Check corners and appliance bays too.
Mark the planned cabinet-top line from the approved finished-height design. Use this one reference throughout the installation rather than measuring up the same distance from the floor beside every cabinet.
Why this matters: identical legs at identical extensions follow the floor’s slope. A level run needs different settings wherever the supporting floor changes height. Account for any flooring still to be installed before fixing cabinet and appliance elevations.
Compare 80–110, 100–130 and 120–150 mm legs
The Berta Store cabinet leveler legs collection has three listed adjustment ranges. Compare your smallest and largest required settings with both limits—not just the rounded inch name.
| Leg range | Approximate inches | Selection rule | Limit to remember |
|---|---|---|---|
| 80–110 mm | 3.15–4.33 in | Every required setting must stay within 80–110 mm. | Does not lower to an exact 3 in. |
| 100–130 mm | 3.94–5.12 in | Every required setting must stay within 100–130 mm. | Does not extend above 130 mm. |
| 120–150 mm | 4.72–5.91 in | Every required setting must stay within 120–150 mm. | 150 mm is not a full 6 in. |
Each range has 30 mm of adjustment. Choosing the tallest model does not provide more leveling travel. Where ranges overlap, favor a suitable setting with adjustment room rather than working against a limit.
Example: settings from 105 to 119 mm
Suppose the mounting details have been checked and your installation needs 105 mm at its highest floor point. A support location 14 mm lower needs 119 mm to maintain the same cabinet elevation.
| Candidate | Covers 105–119 mm? | Reason |
|---|---|---|
| 80–110 mm | No | The 119 mm setting exceeds its maximum. |
| 100–130 mm | Yes, for height | Both endpoints fit; mounting and load suitability still need confirmation. |
| 120–150 mm | No | It cannot lower to the required 105 mm setting. |
If the required span cannot fit a selected model, revise the support plan. Do not overextend the threads or improvise loose stacks beneath the feet to force a fit.
Where should cabinet leveler legs be installed?
The leg must transfer weight into the cabinet’s structural base—not merely into whatever panel is easiest to reach. Follow the cabinet maker’s support layout around sides, partitions and any reinforcement. An unsupported thin bottom is not automatically a suitable mounting surface.
Mounting interface
Match the plate, socket and hole pattern to the leg. Similar-looking replacement feet are not proof of compatibility.
Front setback
Coordinate the mounting location with the toe-kick face and its attachment. Do not guess a universal setback.
Wide or divided cabinets
Have the support layout address partitions, large spans and concentrated loads. Extra supports may be required.
Material and fasteners
Use the specified screw type, engagement and pilot holes for the actual mounting material. Avoid damaged fixing areas.
How many legs does each cabinet need?
Use the cabinet’s support plan, not the pack size. A four-piece pack is not an instruction to put four legs under every cabinet. Include the cabinet, countertop, contents and any supported equipment when checking the complete assembly.
Berta’s listings publish an up-to-330-lb load figure but state that it is not a complete cabinet-system rating. Do not multiply that figure by the number of legs to calculate an installation’s capacity.
For cabinet-body material planning, read the guide to choosing plywood for cabinet boxes. Panel selection does not replace a support layout.
Cabinet leveler legs installation: step by step
Have a tape measure, level or laser, square, clamps, drill with a depth stop, and the specified mounting hardware ready. Work with empty cabinet boxes and enough help to reposition them safely.
-
Confirm the height and support layout
Mark the cabinet-top reference and approved leg positions. Check floor variation, countertop build-up and appliance openings before making holes.
-
Protect and support the cabinet
Place the empty box on a stable, padded work surface in the position allowed by its assembly instructions. Do not rest it on doors or drawer fronts.
-
Attach the mounting components
Position each plate or socket according to the supplied drawing. Use the specified fasteners and drilling depth; do not let screw tips break through the cabinet floor.
-
Fit and preset the legs
Fully engage the connections as directed. Set each leg near its calculated starting height, within the listed limits, and keep the adjustment mechanism accessible.
-
Position the first cabinet
Lift rather than drag the box on its legs. Follow the kitchen layout’s installation order and bring the cabinet to the common top reference. Secure it against tipping as required.
-
Level in both directions
Check across the width and from front to back. Adjust in small increments and recheck the top. Each required foot should bear properly on the floor without twisting the cabinet.
-
Align, join and anchor
Bring the next cabinet to the same reference. Align the boxes before connecting them and complete the required anchoring. Recheck level after tightening; do not use screws to pull a twisted box into place.
-
Verify before covering the base
Check the whole run, appliance openings, support contact and adjustment limits. Obtain the countertop installer’s required base approval before loading it. Measure and fit the toe kick after final alignment.
For an existing installation: unload and independently support the cabinet before removing a foot. Do not work beneath a cabinet supported only by the leg you are replacing. Use a qualified installer when heavy countertops, services or unstable cabinetry prevent safe access.
Leveling one cabinet is not the same as leveling a run
A cabinet can read level by itself but still sit above its neighbor. Use a straightedge or the same laser reference across cabinet joints, checking both the front and rear top edges. The goal is one shared support plane for the countertop.
Across an appliance bay, check the cabinets on both sides rather than starting a new reference from the floor. Verify the appliance opening against its installation requirements and the planned finished floor.
Keep cabinets plumb as well as level. Use the cabinet maker’s specified packing at wall fixings where necessary; pulling a straight cabinet tightly against an uneven wall can change its shape. Recheck after joining and anchoring.
Coordinate the toe kick, clips and appliance clearance
The toe kick, or plinth, is the visible panel in front of the legs. Its height, setback and attachment are separate design decisions. A leg set at 120 mm does not automatically require a toe-kick board cut exactly 120 mm high.
| Detail | What to check | Mistake to avoid |
|---|---|---|
| Face height | Gap beneath the aligned cabinets, floor variation and the specified bottom clearance. | Cutting every piece to the leg’s nominal height. |
| Setback | Toe-space design, panel thickness and attachment position. | Moving legs away from structural support just to hide them. |
| Clips or fixings | Compatibility with the leg and panel; verify supplied contents. | Assuming every clip fits every leg. |
| Floor contour | Whether the lower edge needs scribing to maintain the intended reveal. | Tilting the cabinet run to hide a floor gap. |
| Appliances and services | Door movement, required ventilation and access for maintenance. | Covering an appliance vent or blocking removal. |
Protect freshly cut panel edges with the finish specified for the material. Raising the cabinet off the floor does not protect it from every leak or make plywood and MDF waterproof.

Compare all cabinet leveler legsCommon installation problems
| Problem | Likely issue | Next check |
|---|---|---|
| Cabinet rocks | A support is not bearing, a connection is loose, or the base is distorted. | Inspect every required support and the cabinet structure. |
| One cabinet sits higher | Separate local floor measurements were used. | Return to the common cabinet-top reference. |
| Foot reaches its limit | The selected range does not cover the required setting. | Stop and revise the height or support plan. |
| Doors change alignment after joining | The cabinet may have twisted during fastening. | Check level, plumb and squareness before adjusting hinges. |
| Toe kick shows an uneven gap | The floor contour differs from the panel edge. | Check the panel fit; keep the cabinet run level. |
| Mounting area cracks or moves | Damaged material, unsuitable fixing or an inadequate support layout. | Unload and support safely; repair the structure before continuing. |
Frequently asked questions
What height cabinet leveler legs should I buy?
Calculate the required support settings from the finished height and actual mounting assembly, then check every leg location. Select a range that covers the smallest and largest settings with adjustment room where possible.
Should all adjustable cabinet legs be the same height?
Not on an uneven floor. The cabinet tops should share one level reference, while individual leg settings compensate for changes in floor height.
How do I adjust kitchen cabinet leveling feet?
Use the adjustment mechanism specified for the leg, making small changes while checking level in both directions. Follow any unloading requirements. Do not force a seized foot or exceed the listed adjustment range.
Can I use four legs under every cabinet?
Do not assume a universal leg count. Cabinet size, construction, internal partitions, loads and anchoring all affect the support layout. A pack quantity is not an installation specification.
Does the 120–150 mm model reach 6 inches?
No. Six inches is 152.4 mm. The listed maximum is 150 mm, approximately 5.91 inches; verify how the mounting assembly affects the installed dimension.
Do cabinet leveling legs replace wall fixings?
No. Use the required anchoring for the cabinet run, island or tall unit. Leveling addresses position; anchoring addresses movement and tipping.
Are toe-kick clips and screws included?
Confirm the contents of the selected pack with Berta Store. Check clip compatibility and the fasteners required for your cabinet material rather than assuming that accessories are included.
When should I fit the toe kick?
After the cabinet run is aligned and secured and the relevant installation checks are complete. Measure the actual opening, account for the floor contour and use the specified attachment method.
A level base starts with the measurements
Set the finished elevation, survey the floor, and check the required adjustment at every support point. Mount the legs to the approved cabinet structure, align the run, complete the anchoring and only then finish the base.
Compare the three ranges in the Cabinet Leveler Legs collection once you know your smallest and largest settings.
