About Laminate flooring calculator
This calculator estimates how many laminate or click-vinyl boxes to buy for a rectangular room. Enter length and width in meters, subtract fixed openings such as a hearth or island base, then set plank size and how many square meters come in a pack.
Waste depends on the layout. A straight install often needs about 8% extra. Diagonal cuts and herringbone need more offcuts, so the presets start at 12% and 15%. Waste is applied to the net area before rounding boxes and planks up.
Underlay is ordered from the net floor area plus a small overlap allowance, not from the plank waste percentage. An optional price per box turns the carton count into a material estimate. It does not include adhesive, trims, delivery, or labor.
Results stay in the browser. Pack coverage and plank size should match the product label: some boxes list square meters, others list a piece count. If both differ, trust the printed coverage when ordering cartons.
How to use it
- 1Measure the room in meters and subtract openings that will not be floored.
- 2Pick a layout preset or enter plank size in millimeters and pack coverage in m².
- 3Set waste (8% straight, 12% diagonal, 15% herringbone are common starting points).
- 4Read boxes to buy, plank count, underlay rolls, and the optional material cost.
Frequently asked questions
- How is the box count calculated?
- Net area is length × width minus openings. Order area is net × (1 + waste / 100). Boxes are that area divided by pack coverage, rounded up.
- Why does herringbone need more waste?
- Each piece is cut to keep the angle and the border. A 15% allowance is a planning figure, not a guarantee. Complex rooms with many jogs need more.
- Should underlay use the same waste percentage?
- No. Underlay is ordered from the net floor plus a small overlap (5% in this tool). Plank offcuts are not reused as underlay, and unused plank waste should not inflate the underlay order.
- Is my room size uploaded?
- No. Dimensions are processed locally in the browser and are not sent to a server.
- Does this replace the tile calculator?
- No. Ceramic and porcelain use grout joints and tiles per box. Laminate and vinyl click use plank size, pack coverage in square meters, and layout waste.
