Measure the cabinet’s interior opening and depth, subtract 2–4 inches for clearance, and the resulting diameter is the largest lazy Susan that will fit.
The outside cabinet number is useless — corner cabinets hide usable space behind a face frame and door that both steal inches. The method below covers round, kidney, pie-cut, and blind-corner models, plus the minimum opening requirements that trip people up after the box arrives.
How Do You Measure A Cabinet For A Lazy Susan?
Measure inside depth from the back wall to just inside the door frame, then inside width left to right; use the smaller number minus 2–4 inches as the maximum shelf diameter. Skipping that clearance allowance is why trays arrive and won’t spin.
- Open the cabinet and measure interior depth from the back wall to the inside edge of the door frame.
- Measure interior width left to right at the narrowest point.
- Take the smaller figure and subtract 2–4 inches. The result is the largest diameter that rotates freely.
One sizing guide recommends about 1–2 inches for smooth rotation; the wider 2–4 inch range gives extra room on cabinets with hinges or a raised door lip. Measuring the outside cabinet width ruins the purchase: a nominal 24-inch corner cabinet has a usable interior opening well under 24 inches, and a tray sized to the outside number will jam against the frame.
What Size Lazy Susan Fits Common Cabinet Widths?
Smaller cabinets take 18–22 inch trays, medium 24–28 inches, large 31–32 inches, and extra-large or blind-corner 35–38 inches. A 22-inch tray fits a 24-inch cabinet, while 36- or 39-inch corner cabinets often use a 32-inch lazy Susan. These bands assume the interior opening was measured and clearance subtracted; they narrow options, they don’t replace the tape measure.
| Cabinet Size | Typical Lazy Susan Diameter | Best For |
|---|---|---|
| Small corner cabinet | 18–22 in | Compact base corners, tight door frames |
| Medium cabinet | 24–28 in | Standard base corner cabinets |
| Large cabinet | 31–32 in | Wide base corners, roomy interiors |
| Extra-large / blind corner | 35–38 in | Blind-corner and oversized base units |
| 24-inch cabinet | 22 in | A described good-fit pairing |
| 36- to 39-inch corner cabinet | 32 in | Common large corner pairing |
| Upper-corner wall cabinet | Model-specific | Requires roughly a 20-inch minimum opening |
How Do Kidney, Pie-Cut, And Blind-Corner Models Differ?
Shape determines which cabinets a tray fits, because each style is built around different corner geometry; diameter alone doesn’t guarantee a match.
Rev-A-Shelf’s 6072 Series two-shelf full-circle lazy Susans list cabinet fit ranges of 24–26 inches, 28 inches, 28–30 inches, and 32–34 inches — those numbers describe the cabinet, so match your measured interior to the listed range. Rev-A-Shelf’s 6072 Series fit specifications give the full breakdown.
Kidney-shaped Rev-A-Shelf 6472 Series models come in 24-inch, 28-inch, and 32-inch variants; one 28-inch model is shown with an 18 19/32-inch to 32-inch depth range. Pie-cut and blind-corner units in the Rev-A-Shelf 53-401 Series include 27 3/4-inch and 32-inch width and depth configurations, in MDF and melamine-faced chipboard variants.
Half-moon and blind-corner designs carry requirements beyond diameter. One Rev-A-Shelf 5881-33CR-1 listing is built for 18-1/2 inch base blind corner cabinets, with an 18-1/2 inch minimum opening width and 5-1/2 inch minimum opening height. Upper-corner wall models are stricter: a Rev-A-Shelf 6012-18-11-52 listing calls for a 20-inch minimum opening and a telescoping post adjusting from 24 to 31 inches. Those minimums matter more than diameter in blind-corner and wall installations — if opening width or height falls short, the tray won’t seat no matter how well the diameter matches.
What Should You Check Before Buying?
Confirm three numbers: interior diameter, interior depth, and the minimum opening width and height the specific model requires. A tray that clears on diameter can still fail on depth or mounting height.
- Interior width and depth, measured inside the frame — never the nominal cabinet size.
- Clearance of 2–4 inches subtracted from the smaller dimension, with 1–2 inches as the minimum for smooth spin.
- Minimum opening width and height for blind-corner and wall-cabinet models, listed separately from diameter.
- Shape match: full-circle, kidney, pie-cut, or half-moon, each built for a different corner type.
Once the interior measurement is in hand, a tested roundup of 20 inch lazy susan options is a fast way to compare models in the common small-to-medium band. Pricing varies by retailer and configuration, and the manufacturer listings above publish fit specifications rather than consistent MSRP figures, so check current retail listings for cost.
FAQs
Can I use the outside cabinet width to pick a tray?
No. The outside width includes the face frame and door, which the tray never occupies. Measuring the exterior and ordering to that number usually produces a tray that jams against the frame and won’t rotate. Always measure the interior opening at its narrowest point and subtract clearance before choosing a diameter.
How much clearance does a lazy Susan need to spin?
One sizing guide recommends about 1–2 inches for smooth rotation, while the general method subtracts 2–4 inches from the smaller interior dimension. The wider range is safer on cabinets with hinges, raised door lips, or an uneven interior that narrows the usable opening beyond the frame measurement alone.
Why did my blind-corner lazy Susan not fit even though the diameter matched?
Blind-corner and wall-cabinet models carry minimum opening width and height requirements separate from diameter. A Rev-A-Shelf 5881-33CR-1 listing, for example, calls for an 18-1/2 inch minimum opening width and a 5-1/2 inch minimum opening height. If either falls short, the tray won’t seat properly regardless of its diameter.
