This page explains the measurement or planning assumption behind the result. When you need the project quantity itself, use Kitchen Remodel Cost Calculator.
Start with a dimensioned wall and appliance plan
Record each wall run, door and window opening, appliance width, corner condition and any tall obstruction. Cabinets are modular products with fillers, finished ends and appliance clearances, so a single room perimeter is not a cabinet order. Use Cabinet Linear Feet to summarize usable runs only after the real layout is understood.
Keep cabinet linear feet separate from cabinet count
Linear feet can compare rough scope across layouts, but two kitchens with the same run length can have very different cabinet counts, drawer configurations, tall units and hardware. Do not convert linear feet directly into a cabinet purchase count. The selected manufacturer, cabinet schedule and installer design control the final units.
Measure countertop surfaces from the cabinet geometry
Countertops are priced and fabricated from surface geometry, not simply from kitchen floor area. Measure each run and island, account for the selected depth and overhang, and identify corners or unusual shapes. The Countertop Calculator can estimate area, but fabrication layout, slab yield, seams, sink/cooktop cutouts and edge profiles remain fabricator decisions.
Do not subtract cutouts blindly
Fabricators may price sink and cooktop cutouts differently from raw surface area, and cut pieces may not reduce slab purchases. Keep the gross measured surface and the quote structure visible. A generic calculator should not assume a sink opening reduces purchased slab area or installation labor by the same amount.
Connect quotes to the whole-project budget once
When a cabinet or countertop quote becomes reliable, record it in Purchase Planner and update the overall kitchen budget basis. If the whole-project benchmark already includes that scope, do not simply add the full quote on top without adjusting the benchmark; otherwise the same work is counted twice. The goal is to replace rough assumptions with evidence, not accumulate every number found online.
Planning workflow
Measure wall runs
Capture usable cabinet runs after doors, windows and appliance zones are known.
Build the cabinet schedule
Use the selected cabinet system to turn runs into actual modules, fillers and finished ends.
Measure counter surfaces
Record each run and island as surface geometry independent of kitchen floor area.
Request itemized quotes
Keep fabrication, cutouts, edges, delivery and installation visible.
Replace budget assumptions
Use real quotes to refine the whole-project plan without double-counting scope.
Example: 12 ft cabinet run with an island
A kitchen may have a 12-foot wall cabinet run plus a 7-by-3-foot island countertop. The cabinet run is a linear measurement, while the island contributes 21 square feet of countertop before overhangs or other surfaces. A cabinet quote may include boxes, fronts, hardware and installation, while a countertop quote may include fabrication and cutouts. Keeping the quantities and quote scopes separate makes it possible to update the project budget without pretending one measurement unit can price the other.
Reference table
| Planning layer | Record | Why it matters |
|---|---|---|
| Room geometry | Floor area, wall runs, cabinet runs, countertop and backsplash surfaces | Separates measured quantities from budget assumptions. |
| Scope | What stays, what is replaced, and what moves | Layout/trade movement can change cost more than a small difference in room size. |
| Price basis | Dated benchmark, current quote or supplier price | Prevents a national average from masquerading as a local bid. |
| Risk reserve | Known add-ons plus explicit contingency | Keeps defined work and uncertainty from being mixed together. |
Frequently asked questions
Can I price cabinets from linear feet alone?
Only as a rough comparison if a supplier publishes a compatible linear-foot basis. Real cabinet cost depends on the module schedule, fronts, drawers, accessories, finishes and installation.
Should sink and cooktop openings reduce countertop area?
Not automatically for purchasing or fabrication. A fabricator may still need the surrounding slab and may charge separately for cutouts, so use the quote basis that applies to the selected material.
Why keep cabinet and countertop quotes separate?
They have different measurement bases, vendors and scope boundaries. Separation makes later quote comparison and change tracking more reliable.
Planning note: Product coverage, yield, package size, installation instructions and project requirements take priority over generic examples. Verify the exact product and project before purchasing.
