Hampton Bay and Shenandoah stop at 36 in, Wolf at 42 in; Wellborn goes to 48 in.
The cabinet layout tool needs JavaScript, which is turned off in this browser. The rules it follows are below.
A preliminary box list. The tool fills your walls with generic catalog sizes: widths in 3 in steps from 9 in, 34½ in base cabinets, 30 in, 36 in or 42 in wall cabinets hung at 54 in, and appliance heights it assumes (a 70 in refrigerator, a microwave top at 66 in). Your cabinet line may skip widths (IKEA’s frames do) and size and name its corner, filler and over-the-refrigerator cabinets differently. Nothing carries over from the kitchen layout planner: enter your measured walls here. Before you order, check every box against your chosen cabinet line’s spec guide, and every opening against the appliance’s installation guide.
| Box list | Code | Qty |
|---|
Codes follow the usual catalog pattern (B15 is a 15 in base, W3030 a wall cabinet 30 in wide and 30 in tall); your cabinet line may name them differently. The base run counts the length of wall the base, corner and tall cabinets and the fillers cover; appliance openings and the door space beside a refrigerator are not included.
How the tool fills a wall
- Fixed things first. Appliance openings (refrigerator, range, dishwasher), the sink base, tall cabinets, the corner cabinets and the room kept at each side wall (next step) take their widths. What is left is shared between the stretches marked “Cabinets”, or a stretch takes the length you type in. If the wall is too short for all of it, the tool says by how much.
- Room at the side walls. Whatever stands against a side wall, the tool keeps room for it there. Beside a cabinet (a stretch of cabinets, a sink base, a tall pantry or an oven cabinet) that is a filler of at least 1 in, as Shenandoah’s spec guide asks beside anything deeper, so doors and drawers clear the wall; beside a tall cabinet it is a tall filler. Beside a refrigerator it is 3¾ in of open space, so the door can swing to 90°: the most the Whirlpool and Samsung guides we checked ask for. A range or a dishwasher against a side wall gets no space, and the tool says so: check its installation guide. A filler is cut to fit a wall that isn’t straight.
- Fewest boxes, as even as possible. Each stretch gets the fewest stock cabinets that fit, split as evenly as the 3 in steps allow: 78 in becomes two 39 in boxes, not a 42 in and a 36 in. Anything under 3 in that is left goes into the filler.
- Wall cabinets follow. Above the base run, the same widths, except over the range (a hood, or a microwave with a short cabinet above), over the sink if there is a window, and over the refrigerator (a 24 in deep cabinet). Tall cabinets go to the top of the wall cabinets.
The tool doesn’t check aisles, landing areas or the work triangle; for those, lay the kitchen out first in the kitchen layout planner, then enter each wall’s measurements here. The two tools don’t share a plan: nothing you draw in the planner fills in this tool.
Stock cabinet widths
Stock cabinets come in 3 in steps from 9 in. Hampton Bay (Home Depot) and Shenandoah (Lowe’s) stop at 36 in, Wolf goes to 42 in with 45 in and 48 in by special order, and Wellborn lists 39 to 48 in. IKEA’s SEKTION frames skip 27 in and 33 in. Base cabinets are 34½ in tall and 24 in deep under a 1½ in top, which makes the counter 36 in. Wall cabinets are 12 in deep and hang 54 in above the floor, 18 in above the counter. Every size is in kitchen cabinet sizes.
| Opening or cabinet | Width | Notes |
|---|---|---|
| Refrigerator opening | 30 in, 33 in or 36 in | Beside a side wall, add door space: 2 to 3¾ in in the guides we checked; the tool keeps 3¾ in |
| Range opening | 30 in (24 in or 36 in) | Freestanding and slide-in ranges |
| Dishwasher opening | 24 in (18 in compact) | Next to the sink base; see dishwasher dimensions |
| Sink base | 30 in, 33 in or 36 in | A 30 × 18 in sink needs a 33 in base (Kraus) |
| Lazy susan corner base | 36 in on each wall | One box fills a 36 × 36 in corner (Hampton Bay) |
| Blind corner base | 42 in of its wall | A 33 in box; the other wall starts 24 in out, after a 3 in filler (Hampton Bay Designer Series) |
| Diagonal corner wall cabinet | 24 in on each wall | Fills a 24 × 24 in corner (Hampton Bay) |
| Over the refrigerator | the fridge’s width | 24 in deep, 12 to 24 in tall (Hampton Bay, Shenandoah) |
| Wall oven cabinet | 27 in, 30 in or 33 in | A 30 in oven needs a cabinet at least 30 in wide (Whirlpool) |
| Over an over-the-range microwave | 30 in | Its bottom at least 66 in above the floor |
Corners: lazy susan or blind corner
An L has one inside corner and a U two. The cabinet in the corner reaches into space that the other wall’s cabinets cover, so it is either a lazy susan (a corner box with a turntable that fills 36 in along each wall; 33 in versions exist) or a blind corner cabinet on one wall. A blind corner base is sold by the wall space it fills, not its box width: Hampton Bay’s Designer Series BB42 is a 33 in box for 42 in of wall. The cabinets on the other wall start where the blind box ends, 24 in out from the corner, after a filler: the same guide recommends 3 in so the handles clear each other. Keep the dishwasher at least 21 in from any corner, so there is standing room when its door is open (NKBA).
Fillers and end panels
- At a side wall: at least 1 in on the hinge side (Shenandoah), so the end door and drawers open past the wall; it is cut to fit a wall that isn’t straight. The tool keeps one beside any cabinet that meets a side wall, a sink base or tall cabinet included. Beside a tall cabinet it is a tall filler, which Hampton Bay and Shenandoah sell.
- Beside a refrigerator at a side wall: open space rather than a filler, so the door clears the wall. Whirlpool’s dimension guides ask for 2 to 2½ in on the hinge side; Samsung’s ask for 3¾ in, so the handle doesn’t touch the wall with the door open 90°, and advise against a spot next to a wall if the doors are to open all the way. The tool keeps 3¾ in; your model’s guide decides.
- Beside a range or dishwasher at a side wall: the tool keeps nothing and tells you so; the appliance’s installation guide says how much space it needs there. Side clearances for ranges are on stove dimensions.
- At a corner: 3 in beside a blind corner cabinet keeps the handles from hitting each other (Hampton Bay; Wellborn asks for 2½ in with hardware).
- At an open end: no filler, but the side of the last box shows, so it gets a finished end panel.
- Between cabinets: none needed, except to take up what is left when a stretch isn’t a multiple of 3 in. Stock fillers come 3 in and 6 in wide, and Shenandoah also sells 1 in and 2 in.
From the layout to the price
The tool adds up the base run and the wall run in linear feet, the way cabinet prices are usually quoted. “Price these cabinets” opens the kitchen remodel cost calculator with your base run filled in as the cabinet run (for the countertop, backsplash and refacing estimates) and the base and wall runs added together, which price new cabinets and painting, since Fixr’s per-foot prices for both count upper and lower cabinets together. The 10x10 kitchen cost guide shows the industry’s standard price example, an L of two 10 ft walls, which is also where this tool starts.
Questions people ask
How do I lay out kitchen cabinets?
Measure each wall, mark the corners, the window and where the sink, range and fridge go, then fill the gaps between them with stock widths, leaving fillers at the walls. The tool above does the arithmetic and draws the result.
What width are standard kitchen cabinets?
Stock base and wall cabinets come in 3 in steps from 9 in. Hampton Bay and Shenandoah stop at 36 in; Wolf goes to 42 in, with 45 in and 48 in as special orders.
How do you fill a gap between cabinets?
With a filler strip cut to width, usually at a wall or a corner. A gap of 9 in or more can take a narrow cabinet instead.
How much filler do you need next to a wall?
At least 1 in on the hinge side, Shenandoah’s spec guide says, so the end door and drawers open past the wall. The tool keeps that beside any cabinet against a side wall, a sink base or tall cabinet included, and adds what is left over at the end of a stretch of cabinets to the same filler. A refrigerator against a wall needs open space for its door instead: 2 to 3¾ in in the Whirlpool and Samsung guides we checked.
Final Takeaway
Use the tool for a first box list: it fills each wall with stock widths, fillers and matching wall cabinets, and adds up the linear feet for pricing. Treat that list as preliminary, because your cabinet line’s own widths, heights, corner and filler pieces, and your appliances’ installation guides, set the final sizes. Lay the room out in the kitchen layout planner first, then enter each measured wall here by hand. Check every box against the line’s spec guide before you order.
