Standard base cabinets are 34½ in tall and 24 in deep, so a countertop brings them to 36 in. Wall cabinets are 12 in deep and 30 in, 36 in or 42 in tall. Tall pantry cabinets are 84 in, 90 in or 96 in tall. Widths come in 3 in steps from 9 in: to 36 in on most stock lines, 42 in at Wolf and 48 in at Wellborn.

From the spec guides of Hampton Bay (Home Depot, January 2025) and Hampton Bay Designer Series (September 2025), Shenandoah (Lowe’s, July 2024), Wellborn Select (2024–2025) and Wolf (2021). Heights are of the box, toe kick included; depths don’t count doors. Lines differ in the details, so check your line’s guide before you order.
Base cabinet sizes
Base cabinets carry the counter. All four US lines we read make them 34½ in tall, toe kick included, and 24 in deep, so a 1½ in top brings the counter to the standard 36 in. Widths:
- Hampton Bay: 9 in (a full-height door), 12 to 24 in with one door, 27 to 36 in with two.
- Shenandoah: 12 to 24 in with one door, 24 to 36 in with two.
- Wellborn: 12 to 36 in, then 39 in, 42 in, 45 in and 48 in.
- Wolf: 9 in, then 12 to 42 in; 45 in and 48 in by special order.
The depth is the box. The countertop reaches about 1 to 1½ in past the box, measured from its front (or the face frame), so it still covers the doors and drawer fronts, which stand a little in front of the box. See standard cabinet depth and standard counter depth.
Wall cabinet sizes
Wall (upper) cabinets are 12 in deep in every US line we read; Wellborn notes that anything deeper needs extra support. The main heights are 30 in, 36 in and 42 in, picked to fit the ceiling, with shorter 12 to 24 in cabinets for over the fridge, the range or a window. Widths run 9 to 36 in; Shenandoah also makes 39 in, 42 in and 48 in wall cabinets at 30 in tall. Which height fits which ceiling is on kitchen cabinet height, and how high to hang them on upper cabinet height.
Tall, pantry and oven cabinets
Tall cabinets come 84 in, 90 in or 96 in tall, sized to line up with the tops of 30 in, 36 in and 42 in wall cabinets hung at the standard height (Hampton Bay, Shenandoah). They are 24 in deep to match the base cabinets, or 12 in for a shallow pantry. A tall cabinet needs a little more than its height to be stood up in the room: Wellborn’s rule for 24 in deep ones is the cabinet height plus 4 in of ceiling.
Wall oven cabinets are 27 in, 30 in or 33 in wide (Wellborn); Whirlpool’s guides ask for a cabinet at least 27 in wide for its 27 in ovens and 30 in for its 30 in ones.
Corner cabinet sizes
- Lazy susan base: fills a 36 × 36 in corner (Hampton Bay KBLS36); 33 in versions exist.
- Blind corner base: named by the wall space it fills, not its box. Hampton Bay’s KBBC45 is a 36 in box for 39¼ to 46½ in of wall; its Designer Series BB42 a 33 in box for 42 in. Leave a 3 in filler where the other wall’s cabinets meet it, so the handles clear.
- Diagonal corner wall cabinet: fills a 24 × 24 in corner (Hampton Bay).
To fill a whole wall around its corners with stock widths, use the kitchen cabinet layout tool.
Fillers, toe kicks and panels
- Fillers come 3 in and 6 in wide (Hampton Bay); Shenandoah also sells 1 in and 2 in ones. Shenandoah asks for at least a 1 in filler beside a wall or anything deeper than the cabinet.
- The toe kick is 4 to 4½ in high: 4½ in at Hampton Bay, Wellborn and Wolf, 4 in at Shenandoah. It is set back about 3 to 3½ in: 3⅜ in at Wellborn, 3½ in at Shenandoah.
- Panels: a dishwasher end panel is 1½ in thick at Hampton Bay, and a refrigerator panel kit 24 in deep for 84 in, 90 in or 96 in heights.
IKEA’s cabinet sizes
IKEA’s SEKTION system is metric and sized differently from US framed lines:
- Base: a 30 in frame on 4½ in legs that adjust from 3½ to 5⅛ in, so 34½ in at the standard setting (our arithmetic); 24 in deep. Widths 12 in, 15 in, 18 in, 21 in, 24 in, 30 in and 36 in: no 27 in or 33 in.
- Wall: IKEA calls the system depth 15 in; the frame itself is 14⅜ in deep, 14¾ in on its suspension rail, and about 15½ in with doors. Heights 15 in, 20 in, 30 in or 40 in.
- High cabinets: 80 in or 90 in.
Plan for the deeper uppers if you mix IKEA with other cabinets.
How cabinet codes work
Most lines name cabinets by type and size, in inches: B15 is a 15 in base, SB36 a 36 in sink base, W3030 a wall cabinet 30 in wide and 30 in tall, W361224 a 36 in wide, 12 in tall wall cabinet 24 in deep. Width comes first, then height, then depth when it isn’t standard. Letters vary from line to line, so read the line’s own guide.
Questions people ask
What are standard kitchen cabinet sizes?
Base cabinets 34½ in tall and 24 in deep; wall cabinets 12 in deep and 30 in, 36 in or 42 in tall; tall cabinets 84 in, 90 in or 96 in tall; widths in 3 in steps from 9 in.
How wide are kitchen cabinets?
From 9 in to 36 in in 3 in steps on most stock lines. Wolf goes to 42 in and Wellborn to 48 in.
What size are upper cabinets?
12 in deep, 30 in, 36 in or 42 in tall and 9 to 36 in wide, with shorter 12 to 24 in ones for over a fridge or range.
How tall is a pantry cabinet?
84 in, 90 in or 96 in, to line up with 30 in, 36 in or 42 in wall cabinets.
What size is a sink base cabinet?
30 in, 33 in or 36 in wide in stock lines, 34½ in tall and 24 in deep. The sink’s spec sheet sets the minimum: Kraus’s 30 × 18 in undermount sink, for example, needs a 33 in base, while some sinks of about that size fit a 30 in one. Check the exact model.
Final Takeaway
Plan stock base cabinets at 34½ in tall and 24 in deep, wall cabinets 12 in deep and tall cabinets 84 to 96 in, in widths that step by 3 in. Then work from the spec guide of the line you’ll buy: the widest sizes, corner units and IKEA’s metric SEKTION sizes all differ. Size sink and appliance cabinets from the exact sink or appliance spec sheet, and leave fillers where runs meet walls and corners.
