What is the work triangle warning based on?
It compares the distances between sink, range, and refrigerator against a commonly cited comfortable total range and flags legs that fall well outside it.

Assumptions
- Filler width: 3 in (3 in is the common stock width), counted for gaps up to 12 in. The 12 in cut-off is this tool's own judgement of where a gap stops being filler and starts being a cabinet nobody listed -- nothing published sets it
- Countertop depth: 25.5 in -- a 24 in base cabinet box plus a 1.5 in nosing overhang. Ordinary casework dimensions, not a code figure
- Toe kick stock: 8 ft strips -- 96 in is the length matching finished material is commonly sold in. Estimated, not read from a catalogue; confirm your supplier's stock
- Screws per cabinet: 4, two per mounting rail. Estimated -- jobsite practice, NOT read from a manufacturer's installation instruction. A real count follows the studs each rail crosses, so a wider box takes more
- Wall cabinets: not entered -- uppers not counted
Included: cabinet run layout, work-triangle check, base cabinets, countertop, toe kick, and install screws.
Not included: labor, delivery, permits, disposal of waste material.
Formula details
- Cabinet run available: sum(wallRuns) - sum(openings)
- Filler: runAvailable - sum(cabinetWidths)
- Filler strips: ceil(fillerInches / 3 in per strip)
- Countertop: baseRun x 25.5 in / 12
- Work triangle: d(sink,fridge) + d(fridge,cooktop) + d(cooktop,sink)
The 26 ft ceiling is long-standing kitchen design guidance, not a code requirement. The 13-21 ft target the verdict is measured against is this tool's own rule of thumb -- nothing published sets it.

About this calculator
Enter base and wall cabinet runs plus the three work-triangle points to get linear footage totals and a work-triangle distance warning.
FAQ
Does linear footage include corner cabinets?
Corner runs are entered as part of your base or wall footage totals, so include the full run length for each section you enter.
Can I use this for a galley or single-wall kitchen?
Yes. Enter only the runs that apply and leave the work triangle inputs at your actual fixture and appliance locations.
