Divide by the exact carton coverage, round up, then add any unopened cartons you want for future repairs.

Increase it for diagonal patterns, many small spaces, damaged planks, or selective visual placement. Keep deliberate repair stock separate so it is not consumed during installation."},{"question":"Should I use carton coverage or plank dimensions?","answer":"Use the net square-foot coverage printed on the exact carton for purchasing. Nominal plank dimensions may be rounded, and package counts vary. Plank dimensions are useful for planning rows, but carton coverage is the manufacturer’s direct order quantity."},{"question":"Can vinyl plank cartons from different lots be mixed?","answer":"Different production lots may vary in shade, texture, sheen, or locking profile. Buy one lot when possible and verify every label before opening. During installation, mix planks from several matching cartons to distribute acceptable visual variation."},{"question":"Does vinyl plank flooring need an expansion gap?","answer":"Many floating vinyl plank products require perimeter and fixed-object clearances, but exact dimensions depend on the product, room size, temperature, and installation method. Follow the manufacturer’s current instructions; do not deduct that small gap from the purchasing area."}],"sources":[{"name":"ASTM International — Resilient Floor Covering Standards","url":"https://store.astm.org/products-services/standards-and-publications/standards/resilient-floor-covering-standards.html","note":"Standards index for resilient flooring, including solid vinyl plank and tile specifications and installation-related practices."}],"defaultCalculation":{"inputs":{"length":18,"width":14,"extraArea":24,"boxCoverage":20.06,"waste":10,"spareCartons":1},"result":{"value":"17","unit":"cartons","label":"Total LVP order","lines":[{"label":"Measured floor area","value":"276 sq ft"},{"label":"Area including layout allowance","value":"303.6 sq ft"},{"label":"Installation cartons","value":"16"},{"label":"Reserved spare cartons","value":"1"}],"summary":"Order 17 cartons: 16 for installation plus 1 reserved as entered.","note":"Confirm that all cartons share the same run, lot, color, and locking profile before opening them."}},"reviewedOn":"2026-07-23","disclaimer":"Planning estimate only.
