Upper (wall) kitchen cabinets usually hang with their bottoms 54 in (137 cm) above the floor, which is 18 in (46 cm) above a 36 in counter (KraftMaid, and Hampton Bay's spec guide). The cabinets themselves have no standard height: they come from 12 to 54 in tall. On paper, a 42 in cabinet reaches an 8 ft ceiling, and 36 or 39 in cabinets leave room for crown molding. Over a range, the building code asks for 30 in from the cooktop to combustible cabinets, unless the hood's listing allows less.
Upper cabinet planner
Enter the ceiling, the counter and the gap you want above it, then pick a cabinet height. The planner shows where the cabinets start and end, and how much wall is left above them. For your own kitchen, enter the lowest ceiling or soffit height along the run and the counter height with your actual top on it.
The planner works with nominal sizes, KraftMaid's wall cabinet heights. Real cabinets can differ from their names: American Woodmark's installation guide gives its wall cabinets as 30⅛ to 42⅛ in. So “reaches the ceiling” means it fits on paper. Before you order, check the cabinet's actual height in your line's spec guide, the lowest point of the ceiling or soffit, and how the maker's installation instructions finish the top; American Woodmark's covers the joint between the cabinets and a ceiling or soffit with trim molding.
Standard upper cabinet height
KraftMaid says wall cabinets are typically installed 54 in above the floor, 18 in above the countertop, and that there is no standard height for the cabinets themselves (KraftMaid). Houzz notes that 18 in is the typical minimum and that it has started to creep up to 20 in; any lower and small appliances may not fit under the cabinets (Houzz).
| Measurement | Typical | Source |
|---|---|---|
| Floor to the bottom of the uppers | 54 in | KraftMaid; Hampton Bay spec guide |
| Counter to the bottom of the uppers | 18 in, now often 20 in | KraftMaid; Hampton Bay; Houzz |
| Shenandoah’s drawing | 53⅞ in (17⅞ in above the counter) | Its 30, 36 and 42 in cabinets are ⅛ in taller than their names |
| Wall cabinet heights | 12 to 54 in | KraftMaid |
| To reach an 8 ft ceiling | 42 in cabinets | KraftMaid |
| With room for crown molding | 36 or 39 in cabinets | KraftMaid |
| Taller ceilings | 48, 51 or 54 in cabinets | KraftMaid |
| Wall cabinet depth | 12 in (24 in above a fridge) | KraftMaid |
Base cabinets are 34½ in tall, 36 in with the countertop; see standard counter height and standard cabinet depth. Tall pantry cabinets run 84 to 96 in, and a 90 in pantry lines up with the top of a 36 in wall cabinet hung at 54 in (KraftMaid). Every cabinet height, base to tall, is on kitchen cabinet height, and the widths on kitchen cabinet sizes.
Upper cabinet height by ceiling height
With the uppers starting at 54 in, the wall left for them is the ceiling height minus 54 in. Lines that go to 54 in tall, like KraftMaid's, can fill it with one cabinet; lines that stop at 42 in, like Hampton Bay's, stack a short cabinet on top:
| Ceiling | Wall above 54 in | Up to 54 in tall (KraftMaid) | Up to 42 in tall (Hampton Bay) |
|---|---|---|---|
| 8 ft (96 in) | 42 in | 42 in to the ceiling; 36 or 39 in with crown molding | 42 in to the ceiling; 36 or 30 in leave 6 or 12 in |
| 9 ft (108 in) | 54 in | 54 in to the ceiling; 48 in with crown molding | 42 in plus a 12 in stacked cabinet; or 42 in, leaving 12 in |
| 10 ft (120 in) | 66 in | 54 in plus a 12 in stacked cabinet; or 54 in with space above | 42 in plus a 24 in stacked cabinet |
Our arithmetic with each line's nominal heights: KraftMaid's wall cabinets run 12 to 54 in, and stacking a short cabinet on top is one of the uses it gives for those under 36 in; Hampton Bay's run 12 to 42 in, and its guide suggests stacking short cabinets on taller ones.
All of this is on paper. Real cabinets can be a little taller than their names: American Woodmark's guide, for example, hangs its 30⅛ to 42⅛ in cabinets 53⅞ in above the floor's high point, so their tops land at 84 to 96 in. A stacked cabinet adds its own actual height, and a ceiling may not be level along the run. Plan from the actual cabinet heights in your line's guide and the lowest point of the ceiling or soffit.
Starting the cabinets higher changes the whole column: at 20 in above a 36 in counter they start at 56 in, and an 8 ft ceiling leaves 40 in. The planner above does this for any ceiling.
Over the range, sink and island
- Over a range: the 2021 IRC asks for at least 30 in above the cooking top to unprotected combustible material, such as a wood cabinet; less is allowed only where the range hood's or oven's listing permits it (M1901.1). The NKBA's guidelines give 24 in to a protected, noncombustible surface. Range makers' guides say the same: Whirlpool's ask for 30 in from the cooktop to an unprotected cabinet (24 in if it is shielded), and for the uppers beside the range at least 18 in above the counter and no more than 13 in deep. Range sizes are on stove dimensions, and how high the hood goes on range hood height.
- Over-the-range microwave: its maker's installation instructions set the clearance. GE's ask for the cabinet above to start at least 30 in above the cooking surface and the top of the microwave to be at least 66 in above the floor; see microwave dimensions. The NKBA suggests putting a microwave's bottom 3 in below the main user's shoulder, and no more than 54 in above the floor.
- Over a sink: Houzz suggests cabinets 24 to 30 in above the counter there, for more room to work.
- Over an island: cabinets 48 to 54 in above the counter keep a view across an open plan (Houzz).
Reach and the top shelf
Hung at 54 in, a 42 in cabinet ends at 96 in. The NKBA counts storage more than 84 in above the floor as "miscellaneous" rather than everyday storage. For a wheelchair user, the ADA high reach is 48 in, or 44 in when reaching over a counter 20 to 25 in deep (2010 ADA 308.2), which is below where upper cabinets start.
How to hang upper cabinets at the right height
Floors are not always level, so a line measured 54 in up from the floor in one spot can run out of level along the wall. Cabinet makers' installation guides start from a level line instead. American Woodmark's, for example:
- Find the floor's high point. Check along the wall with a level and mark the highest spot. Measure the ceiling or soffit in several places too, and note its lowest point.
- Draw the base line. From the high point, measure up 34½ in, the top of the base cabinets, and draw a level line along the wall; if the flooring goes in later, add its thickness. Measure everything else from this line, not from the floor.
- Mark the bottom of the uppers from the finished counter: the base line, plus your countertop's actual thickness, plus the gap you want. American Woodmark's guide marks its line 19⅜ in above the base line, 53⅞ in above the floor's high point.
- Mark the top line. Add the cabinet's actual height and check it clears the lowest point of the ceiling or soffit.
- Mark the studs along both lines and screw a level support rail into them just under the bottom line, to hold the cabinets while you fasten them. Wall cabinets are fastened through their backs into the framing; follow your cabinet maker's installation instructions, or have an installer hang them.
- Over the range, raise the bottom line to leave at least 30 in above the cooktop, unless the hood's instructions allow less.
Questions people ask
How high are upper cabinets above the counter?
Usually 18 in, which puts their bottoms 54 in above the floor (KraftMaid, Hampton Bay). Many kitchens now use 20 in (Houzz).
How high are upper cabinets from the floor?
54 in to the bottom of the cabinets on a standard 36 in counter. A 30 in cabinet then ends at 84 in, a 36 in one at 90 in and a 42 in one at 96 in.
How tall should upper cabinets be for an 8 ft ceiling?
42 in, to reach the ceiling from 54 in up, on paper; check the real cabinet's height and the ceiling's lowest point before you order. Choose 36 or 39 in to leave room for crown molding or lighting on top.
How tall should upper cabinets be for a 9 ft ceiling?
From 54 in up there are 54 in of wall: KraftMaid's 54 in cabinets fill it, and 48 in ones leave room for crown molding. In a line that stops at 42 in, such as Hampton Bay's, stack a 12 in cabinet on a 42 in one, or leave 12 in open above.
Are upper cabinets 30 or 36 in tall?
Both are common; KraftMaid makes wall cabinets from 12 to 54 in tall. On an 8 ft ceiling, a 30 in cabinet leaves 12 in of wall above it, a 36 in one 6 in.
Is 20 in too high between the counter and the uppers?
No. Houzz notes 20 in is becoming common. It gives more room for appliances; under a fixed ceiling, it costs 2 in of cabinet height.
How high should cabinets be above a stove?
At least 30 in above the cooking top to a combustible cabinet (2021 IRC M1901.1), unless the range hood's listing allows less.
Final Takeaway
Hang uppers about 18 in above the finished counter, which is 54 in above the floor on a standard 36 in counter, and measure from a level line struck from the floor's high point rather than from the floor itself. Choose the cabinet height from the wall left between that line and the lowest point of the ceiling or soffit: a nominal 42 in cabinet fills an 8 ft ceiling, and 9 or 10 ft ceilings take taller or stacked cabinets. A cabinet that reaches the ceiling on paper may not in your room, so check its actual height in your line's guide before you order. Over a range, keep 30 in above the cooktop unless the hood's listing allows less.
