Base cabinet dimensions

Start with the base cabinets because they set the countertop height and depth. A base cabinet is typically 24 inches deep and 36 inches high to the top of the counter.¹ One maker breaks that height into a 34½-inch cabinet box and a 1½-inch countertop.² ³

Countertops in the sourced range are 24 to 26 inches deep.³ The toe kick is about 4 inches high, with a recess of 3 inches in one maker's specification and 3½ inches in another.⁵ ⁷ Put the box, countertop and toe kick on the same side section.

A shallow base can work where a full-depth cabinet takes too much room. One maker lists base depths of 21 or 24 inches.³ Another offers reduced depth in 1-inch steps, shows a 17-inch example and asks for the total cabinet depth on the order.⁹

Base cabinet side section labeled box 34½, countertop 1½, finished height 36, cabinet depth 24, countertop 24 to 26, toe kick 4 high, recess 3 to 3½, Dimensions in inches, and Illustrative. — The base section shows a 34½-inch box, 1½-inch countertop, 36-inch finished height, 24-inch cabinet depth, 24-to-26-inch countertop and a 4-inch toe kick recessed 3 to 3½ inches; the drawing is illustrative.

Wall (upper) cabinet dimensions

Next, pick the wall cabinet depth and height. Wall cabinets are typically 12 inches deep, while one maker also lists 15-, 18- and 24-inch depths.¹ ³ An over-refrigerator wall cabinet can be 24 inches deep, but its size still has to follow the appliance opening.³ ⁴

Wall cabinet heights typically run from 12 to 42 inches.¹ Common full-height boxes are 30, 36 and 42 inches, while short boxes include 12, 15, 18 and 24 inches.³ ⁴ Your ceiling, crown molding and appliance openings decide which box height works in each part of the run.

The common gap above the counter is about 18 inches.³ With a 36-inch counter, that puts the wall cabinet bottom about 54 inches from the floor.¹ ³ The appliance garage guide uses the same 18-inch gap and explains why the clear opening inside a garage will be smaller.

Kitchen wall section labeled toe kick 4, counter 36, gap 18, bottom of wall cabinets 54, wall box 30, 36, or 42, Dimensions in inches, and Illustrative. — The wall section shows a 4-inch toe kick, 36-inch counter, 18-inch gap, 54-inch wall-cabinet bottom and 30-, 36- or 42-inch wall box; the drawing is illustrative.

How high to hang upper cabinets, by ceiling height

Use the common 54-inch cabinet-bottom line to compare wall boxes.¹ ³ A 30-inch box ends at 84 inches, a 36-inch box ends at 90 inches and a 42-inch box ends at 96 inches.¹ ³ The table shows how much room remains below 8-, 9- and 10-foot ceilings.¹ ³

Wall box	Cabinet top	Space below 8-foot / 96-inch ceiling	Space below 9-foot / 108-inch ceiling	Space below 10-foot / 120-inch ceiling¹ ³
30 inches¹ ³	84 inches	12 inches	24 inches	36 inches
36 inches¹ ³	90 inches	6 inches	18 inches	30 inches
42 inches¹ ³	96 inches	0 inches	12 inches	24 inches

One maker uses a more exact 53⅞-inch bottom line and a 17⅞-inch gap above a 36-inch counter.⁷ Its 30⅛-, 36⅛- and 39⅛-inch wall cabinets end at 84, 90 and 93 inches.⁷ Crown molding, soffits and uneven ceilings can change the space above the boxes.

Three wall-cabinet elevations labeled ceiling 96, 108, and 120, cabinet bottom 54, wall boxes 30, 36, and 42, space left 12, 6, and 0 under 96, 24, 18, and 12 under 108, 36, 30, and 24 under 120, Dimensions in inches, and Illustrative. — With cabinet bottoms at 54 inches, 30-, 36- and 42-inch wall boxes leave 12, 6 and 0 inches below an 8-foot ceiling, 24, 18 and 12 inches below a 9-foot ceiling, and 36, 30 and 24 inches below a 10-foot ceiling; the drawing is illustrative.

Tall cabinet dimensions

Tall utility and pantry cabinets are typically 12 or 24 inches deep and 84 inches or taller.¹ Tall oven and refrigerator cabinets are typically 24 inches deep and 84 inches or taller.¹ Use the appliance maker's cutout specification for either appliance cabinet.

The pantry cabinet guide covers the additional heights, depths and storage layouts.

Tall cabinet elevation labeled 84 or taller, 12 or 24 deep, base cabinet 24 deep, counter 36, Dimensions in inches, and Illustrative. — The tall cabinet is 84 inches or taller and 12 or 24 inches deep beside a 24-inch-deep base cabinet and 36-inch counter; the drawing is illustrative.

Standard cabinet widths and where custom sizes help

One maker offers base and wall cabinet widths from 9 to 48 inches in 3-inch steps.³ Availability changes by cabinet line, so check the exact sizes before the drawing is approved. The big-box and custom cabinet guide explains how stock sizing and fillers affect a run.

Take an illustrative 100-inch wall. Stock cabinets at 33 + 33 + 30 inches make a 96-inch run, leaving 4 inches for filler.³ A custom run can be built to the full 100 inches. The stock, semi-custom and custom cabinet guide explains the choices without repeating them here.

Cabinet width plan labeled 3-inch steps, wall 100, stock 33 + 33 + 30 = 96, filler 4, custom 100, Dimensions in inches, and Illustrative. — On a 100-inch wall, stock cabinets at 33 + 33 + 30 inches make a 96-inch run with 4 inches of filler, while the custom run is 100 inches; cabinet widths step by 3 inches; the drawing is illustrative.

Corner and sink base cabinets

Corner cabinets need their own plan view because the wall space is easy to miss on an elevation. In one maker's line, a rotating corner base takes 33 × 33 or 36 × 36 inches along the two walls.⁸ A blind corner base from the same maker needs 38¼ to 40 inches of wall on its long side.⁸

For a sink base, start with the sink specification. One maker tells buyers to check the sink specification and choose a cabinet that can hold it.⁶ Put the sink, plumbing space, doors and nearby corner cabinet on the same plan before you request a quote.

Corner cabinet plan labeled rotating corner 33 × 33 or 36 × 36, blind corner wall space 38¼ to 40, one maker, Dimensions in inches, and Illustrative. — One maker's rotating corner base takes 33 × 33 or 36 × 36 inches along the walls, while its blind corner base needs 38¼ to 40 inches on the long side; the drawing is illustrative.

What to put on the drawing and in the quote

Each cabinet's width, height and depth
Finished countertop height, thickness and depth
Wall-cabinet bottom line and clear counter gap
Toe-kick height and recess
Fillers, finished panels, crown molding and soffits
Tall, corner and sink cabinet types
Appliance openings from the appliance maker's specifications
Door, drawer and hardware clearances

Ask each cabinetmaker to price the same approved drawing. The quote should identify the cabinet line or construction, door style, finish, fillers, panels, trim, hardware, delivery and installation.
