Download the pre-rendered example CSV or inspect the versioned model JSON. The interactive download buttons use the current browser inputs, while these two static files preserve the reviewed default example.

The answer first: what the default model produces

With the reviewed defaults, this toe-kick platform produces 3 named part lines: Front and rear platform rail, End sleeper, Intermediate sleeper. The generator expands those formulas into 5 rectangular pieces covering approximately 3.21 square feet of finished face area. That area is useful for comparing configurations, but it is not a sheet purchase quantity because packing, kerf, edge trim, defects, grain, spare pieces, and purchasable stock formats still have to be modeled separately.

The default footprint begins with a 30-inch cabinet width and 24-inch depth. A 3-inch front recess, 0.75-inch inset at each side, 4-inch member width, and 0.75-inch stock define the frame. Deducting both side insets makes each of the two long rails 28.5 inches. Sleeper length is cabinet depth minus the front recess minus two stock thicknesses, producing 19.5 inches for both end sleepers. Dividing the 28.5-inch platform width by the entered 24-inch planning interval, rounding up, and subtracting one yields 1 intermediate sleeper of the same 19.5-inch length. That count estimates layout only; it does not approve the load path.

Formula model and variable definitions

The current model uses these project inputs: Cabinet outside width, Cabinet outside depth, Platform height, Front toe-kick setback, Setback at each side, Platform stock thickness, Planning support spacing. Each input has a visible default, allowed range, increment, and measurement note. Formulas are deliberately limited to arithmetic and a small group of rounding helpers so a reviewer can read the rule without executing opaque code. The static JSON repeats the same expressions used by the browser runtime and the default build check.

Enter a 6-inch cabinet depth, a 5.5-inch front setback, and 0.25-inch platform stock. The sleeper equation becomes 6 minus 5.5 minus two times 0.25, exactly zero. A similar width failure occurs when a 6-inch cabinet has a 3-inch side setback on both sides, leaving zero-length rails. Neither arrangement creates a physical platform rectangle. The page rejects the nonpositive output and asks for a coherent footprint instead of disguising the problem by clamping the affected member to 0.01 inch.

Measure the inputs before trusting the output

The toe-kick platform model is controlled by Cabinet outside width, Cabinet outside depth, Platform height, Front toe-kick setback, Setback at each side, Platform stock thickness, Planning support spacing. Record those values from the named physical datums in this order:

1. Measure the cabinet footprint and identify whether the platform is one module or a continuous run.
2. Map the finished floor high point, low point, slope, obstructions, and required leveling method.
3. Record front and side recesses from the same finished cabinet faces used on the elevation.
4. Confirm actual platform-stock thickness and the assembly method before calculating sleeper length.
5. Dry-fit or template one platform, confirm level and load path, then release repeated modules.

Declared assumptions and project boundaries

• Front and rear rails use the same thickness and the sleepers fit between them.
• The rear platform edge is flush with the modeled cabinet depth; a service chase or rear recess must be modeled separately.
• Support spacing estimates part quantity only and does not establish allowable load, deflection, fastener capacity, or substrate adequacy.
• This is a reviewable planning model, not a universal cabinetmaking standard; the shop drawing, approved sample, field dimensions, and contract documents remain authoritative.
• Manufacturer hardware dimensions, load ratings, fastener schedules, edge distances, and drilling requirements govern whenever hardware is involved.

Validation checks before material is released

1. Confirm platform width plus both side setbacks reproduces the intended cabinet width.
2. Check the floor survey and leveling plan before treating every vertical member as the same height.
3. Verify sleepers, seams, cabinet sides, fastening points, and concentrated loads share an approved load path.
4. Measure the actual sheet, board, or panel thickness from the material lot and reconcile it with every mating groove, dado, fastener, and hardware allowance.
5. Build or dry-fit the first assembly, record the verified result, and release the remaining batch only under the same model revision.

Common mistakes and how to prevent them

• Using a familiar sleeper spacing as if it were a verified structural capacity.
• Deducting the front recess twice by mixing cabinet-depth and platform-depth reference planes.
• Treating nominal material thickness as measured thickness and carrying the resulting error through every fitted component.
• Releasing an entire batch before a first-piece dry fit proves the dimension chain, orientation, and assembly sequence.

How CSV, JSON, and the project tray should be used

Export the Front and rear platform rail, End sleeper, Intermediate sleeper rows with model 1.0.0, then reconcile the Platform stock material group before layout. CSV carries the rectangular rows; JSON retains inputs and formula metadata; the browser-local project tray combines this result with other reviewed components.

Method, versioning, and reproducibility

Model 1.0.0, reviewed 2026-07-30, publishes 7 bounded inputs and 3 named output formulas under the stable canonical /tools/components/toe-kick-platform-cut-list-calculator/. The build rejects unknown expression identifiers and nonpositive default dimensions; the browser rejects live combinations that calculate a zero or negative part instead of silently substituting a token size. Entered dimensions never create another indexed URL.
