Kitchen Cabinet Linear Feet Calculator

The kitchen cabinet linear feet calculator divides each run length by an average cabinet width, 24 in. by default, and rounds to a whole cabinet. It also returns total linear feet of base and wall cabinets, which cabinetry is often priced by.

How to Calculate Kitchen Cabinet Linear Feet

Cabinets are sold in standard width increments, commonly every 3 in. from 9 in. up to 36 in. So a rough cabinet count divides your total run length by a representative average module width (commonly 24 in.) and rounds to the nearest whole cabinet. This gives a starting cabinet count for a preliminary layout or budget estimate. It comes before a kitchen designer or cabinet supplier fits actual specific-width units (corners, fillers, appliance gaps) to your exact space.

Example: Kitchen with 20 ft of base cabinet run and 16 ft of wall cabinet run

A kitchen with 20 ft of base cabinet run and 16 ft of wall cabinet run, using a 24 in. average module width: 1. Base cabinets: round(20 × 12 ÷ 24) = round(10) = 10 2. Wall cabinets: round(16 × 12 ÷ 24) = round(8) = 8 3. Total linear feet: 20 + 16 = 36 ft That's roughly 10 base cabinets, 8 wall cabinets, and 36 total linear feet of cabinetry.

Scenario	Base Cabinets (approx.)	Wall Cabinets (approx.)	Total Cabinet Linear Feet
Small kitchen (12 ft base, 8 ft wall run)	6	4	20.0 ft
Medium kitchen (20 ft base, 16 ft wall run)	10	8	36.0 ft
Large kitchen (36 ft base, 28 ft wall run)	18	14	64.0 ft

What Is Kitchen Cabinet Linear Feet?

A kitchen cabinet linear feet calculator converts total base and wall cabinet run lengths into an approximate cabinet count, using a standard average module width. It's a quick early-planning estimate for budgeting or comparing quotes priced per linear foot, which is how many kitchen cabinet lines are sold.

Kitchen Cabinet Linear Feet: Pros and Cons

Pros

Gives both an approximate cabinet count and a total linear footage figure, since cabinet pricing is often quoted per linear foot
Adjustable average module width, since kitchens can be planned around narrower or wider standard cabinet sizes
A quick early-budgeting estimate before a detailed cabinet layout is finalized

Cons

This is a rough average-width estimate, not an actual cabinet layout. A real kitchen design uses a specific mix of cabinet widths, including corner units, fillers, and appliance gaps, that a flat average doesn't capture
Doesn't account for islands, peninsulas, or specialty cabinets (lazy susans, pull-out pantries), which are typically priced and counted separately from standard runs
A cabinet designer or supplier's detailed layout should always be the final word on exact cabinet count and sizing before ordering

Kitchen Cabinet Linear Feet: What a Pro Checks

Treat this as a rough starting number, not a final cabinet order. A real kitchen layout uses a specific mix of widths (corner units, fillers, appliance gaps) that a flat average width can't capture.
Add islands, peninsulas, and specialty cabinets (lazy susans, pull-out pantries) separately. They're typically priced and sized outside a standard base or wall run.
Get a cabinet designer or supplier's detailed layout before ordering. It should be the final word on exact cabinet count and sizing, not this average-width estimate.

Frequently Asked Questions

How many cabinets do I need for my kitchen?

As a rough estimate, divide your total base (or wall) cabinet run length by a standard average module width (commonly 24 in.) and round to the nearest whole cabinet. A 20 ft base run at 24 in. average width gives about 10 cabinets.

What is a standard cabinet width?

Cabinets commonly come in 3 in. increments from 9 in. up to 36 in. wide. 24 in. is a very common base cabinet width, and it's used here as a reasonable average for a quick estimate.

How is kitchen cabinetry priced?

Often per linear foot of cabinet run, with base and wall counted separately and sometimes at different rates. That is why this calculator reports total linear feet alongside an approximate cabinet count. It's useful for comparing quotes.

What's the difference between base and wall cabinets?

Base cabinets sit on the floor and typically support the countertop. Wall cabinets mount above the counter at eye level. They're usually different depths and heights, and are counted and priced separately.

Does this calculator account for a kitchen island?

No. Islands and peninsulas are typically custom-sized and priced separately from standard base and wall cabinet runs. Add their linear footage and cabinet count separately from this estimate.
