Flooring Calculator
Calculate material quantities for broadloom carpet, carpet tile, LVP, laminate, engineered hardwood, and sheet vinyl
Use this flooring material planning screen to run preliminary takeoff math for flooring installers, general contractors, and homeowners. The tool totals room rectangles and estimates cartons, rolls, sheet length, carpet tile counts, underlayment, transitions, and stair accessories from editable local defaults. Treat the output as a source-aware screen only: verify product labels, lot or dye-lot requirements, seam diagrams, concrete moisture limits, substrate preparation, and manufacturer installation instructions before ordering or installing.

-
Select Flooring Type
Choose broadloom carpet, carpet tile, LVP, laminate, engineered hardwood, or sheet vinyl. The output format changes by local category, but product packaging and manufacturer instructions remain the controlling source.
-
Enter Room Dimensions
Input each measured rectangle. Break L-shaped or irregular rooms into sections, then review islands, cabinets, columns, angled walls, and permanent fixtures outside the app before ordering.
-
Set Product Specifications
Enter carton coverage, roll width, transitions, stairs, and material price from the actual product label or supplier quote. Do not use the sample defaults as a purchase order.
-
Review Material List
Use the output as a preliminary material list and reconcile it with seam layouts, pattern repeats, dye lots, moisture reports, substrate prep, old-flooring hazards, and installer/manufacturer review.
Built For
- Flooring contractors preparing material takeoffs for residential renovation bids
- Property managers ordering flooring for multi-unit turnover with consistent room layouts
- DIY homeowners calculating how many cartons of LVP or laminate to order from the home center
- Commercial flooring installers estimating carpet tile quantities for office buildouts with furniture cutouts
- General contractors budgeting flooring material costs during the estimating phase of a remodel
Assumptions
- Room dimensions are assumed to be rectangular. Irregular rooms should be broken into rectangular sections.
- Waste factors are local planning defaults and must be replaced with product, pattern, seam, installer, and supplier-specific values.
- Underlayment, pad, adhesive, spacer, tack strip, transition, and stair accessory quantities are local package assumptions.
- Carton coverage must come from the manufacturer label and be reconciled with lot rules, stagger, starter length, room transitions, and product instructions.
Limitations
- Does not generate visual seam layout diagrams for broadloom carpet or sheet vinyl.
- Does not calculate subfloor preparation materials (leveling compound, plywood, backer board).
- Does not account for furniture removal, disposal fees, demolition, asbestos, silica, lead, mold, or hazardous-material controls.
- Does not approve radiant heat compatibility, expansion gaps, moisture limits, warranty compliance, code/AHJ acceptance, or substrate readiness for specific products.
