Cabinet Calculator

A cabinet calculator is a kitchen planning tool that estimates the number of cabinets, linear feet, and total cost for a kitchen remodel based on the kitchen layout, wall dimensions, and cabinet quality level. Kitchen cabinets are one of the largest expenses in a renovation, typically accounting for 30-40% of the total kitchen remodel budget. Accurate planning ensures that you order the right number of cabinets, stay within budget, and achieve the functional layout you desire.

Kitchen cabinets are measured in linear feet, which represents the total length of cabinetry along the walls. A standard kitchen base cabinet is 24 inches deep and 34.5 inches tall (without countertop), while wall cabinets are typically 12-15 inches deep and 30-42 inches tall. The calculator accounts for these standard dimensions when computing costs and hardware requirements.

The kitchen layout is the primary factor that determines how many linear feet of cabinets are needed. A single-wall kitchen has cabinets along one wall, a galley kitchen has cabinets along two parallel walls, an L-shaped kitchen has cabinets along two perpendicular walls, and a U-shaped kitchen has cabinets along three walls. Each layout type has a different ratio of linear feet to wall length, which the calculator computes automatically.

Beyond basic cabinet count, the calculator estimates the number of cabinet doors, drawers, hinges, and pulls needed. It also calculates the countertop square footage, which is useful for budgeting countertops separately. The hardware estimates are based on industry averages and provide a reasonable starting point for purchasing.

Cabinet costs are calculated based on linear footage and the cabinet quality level. The total cost includes both the cabinet material cost and the installation labor cost, which are typically quoted separately by contractors.

The calculator computes linear footage based on the kitchen layout type and wall lengths, then multiplies by the per-foot cost for the selected quality level. Base cabinets, wall cabinets, and tall cabinets have different proportions, which the calculator accounts for using industry-standard ratios.

Understanding standard cabinet dimensions is essential for accurate kitchen planning. The three main categories of kitchen cabinets each have specific standard sizes.

Base cabinets sit on the floor and support the countertop. They are 34.5 inches tall (without countertop), 24 inches deep, and range from 12 to 48 inches wide in 3-inch increments. With a standard 1.5-inch countertop, the total height is approximately 36 inches, which is the standard counter height. Common widths include 24 inches (for sinks), 30 inches (for ranges), and 36 inches (for general storage).

Wall cabinets mount to the wall above the countertop. They are typically 30, 36, or 42 inches tall and 12-15 inches deep. The depth is less than base cabinets to provide headroom while working at the counter. Wall cabinets come in the same width range as base cabinets and are positioned to align with the base cabinet layout below.

Tall cabinets (also called pantry or utility cabinets) extend from floor to near ceiling height, typically 84-96 inches tall and 24 inches deep. They provide maximum storage in a compact footprint and are often placed at the end of a cabinet run or in a corner. Common widths are 18, 24, and 30 inches.

Follow these steps to estimate cabinet requirements and costs for your kitchen:

1. Select Kitchen Layout: Choose from Single Wall, Galley, L-Shaped, or U-Shaped. Each layout uses different calculations for linear footage.
2. Enter Wall Lengths: Input the main wall length and, for L and U layouts, the secondary wall length(s) in feet.
3. Set Ceiling Height: The ceiling height affects wall cabinet sizing options but does not change the linear footage calculation.
4. Toggle Kitchen Island: If your kitchen includes an island, check the box and enter the island length. The calculator adds both sides of the island to the base cabinet count.
5. Select Cabinet Quality: Choose from Stock ($100/ft), Semi-Custom ($250/ft), or Custom ($500/ft). These prices include the cabinet boxes, doors, and basic hardware.
6. Review Results: The calculator displays total linear feet, base and wall cabinet feet, door and drawer counts, hardware estimates, countertop square footage, and a complete cost breakdown.

Kitchen cabinet planning is one of the most important steps in a kitchen remodel. The cabinets define the kitchen's layout, determine storage capacity, and represent the largest single expense in most kitchen renovations. Accurate cabinet estimates help homeowners set realistic budgets, compare contractor bids, and make informed decisions about cabinet quality levels.

For homeowners planning a DIY kitchen remodel, the cabinet calculator provides a starting point for determining how many cabinets to order and what sizes are needed. While the calculator gives linear footage totals, the actual cabinet order will include specific cabinet types (base, wall, corner, lazy Susan, etc.) that must be selected based on the kitchen's layout and the homeowner's storage needs.

For homeowners working with a kitchen designer, the calculator helps verify the designer's estimate and provides a basis for comparing the designer's recommendation with alternative layouts. Understanding linear footage also helps when comparing bids from multiple contractors, as some may quote based on linear feet while others use a lump-sum price.

The hardware estimates (hinges, pulls, and knobs) are useful for budgeting the finishing touches that many homeowners overlook. High-quality cabinet hardware can cost $5-$15 per piece, and a typical kitchen may need 40-80 pieces, adding $200-$1,200 to the total project cost.
