Flooring Calculator
Typical Coverage per Box
Tips
- Always buy from the same lot number to ensure consistent color. Lot numbers are on the box label.
- Acclimate new flooring to your home's temperature and humidity for 48–72 hours before installation to prevent expansion or contraction.
- Diagonal installations require more cuts and more waste — use 15% instead of 10%.
- Factor in underlayment, adhesive, and transition strips when budgeting total project cost.
Frequently Asked Questions
How much extra flooring should I buy?
The standard recommendation is 10% extra for waste and cuts. For diagonal installations or complex room shapes, use 15%. For large-format tiles or highly figured hardwood, 10–15% is also appropriate. Buying extra from the same lot ensures color and texture consistency — it's difficult to match batches later.
How many square feet are in a box of flooring?
It varies by product. Typical ranges: laminate 15–25 sq ft per box, luxury vinyl plank 18–25 sq ft, hardwood 20–22 sq ft, ceramic tile varies widely. Enter your specific product's coverage in the calculator for exact box counts.
Do I measure the full room including under cabinets?
Measure the full room dimension — include the space under cabinets, appliances, and toe kicks. Flooring is typically installed under or behind these items (or at minimum, needs material cut to fit). For kitchen islands, subtract only if the island is a fixed structural element, not if it sits on the floor.
What is the best flooring for high-traffic areas?
Luxury vinyl plank (LVP) and ceramic/porcelain tile lead for high-traffic and moisture-prone areas (kitchens, bathrooms, entryways). Hardwood adds value but is sensitive to moisture. Laminate is budget-friendly but less durable with moisture. Carpet is comfortable but harder to clean in high-traffic zones.
