Estimate flooring boxes, approximate planks/tiles and material cost — metric or imperial.
For L-shaped rooms, add up each rectangular section first and enter the combined total here, or switch to "Calculate from room dimensions" above.
Enter your specific product's coverage per box from its label - this varies by brand, plank/tile size and product line.
A straight/parallel layout typically involves the least waste. Choose the waste allowance recommended for your product and layout below.
Leave at 0 to skip the approximate piece count and see only the box count. This is an approximate area-based piece count for reference only - order quantity should be based on whole boxes/product packaging.
Enter a whole number to see total pieces supplied vs. approximately required and spare. Leave at 0 to skip.

Enter a total area, or switch to "Calculate from room dimensions" and add one or more rectangular rooms/sections - they're summed automatically. Enter your specific flooring product's coverage per box from its label, choose a layout for waste guidance (the waste % itself stays independently editable), and optionally enter plank or tile dimensions for an approximate piece count. Use the Cost tab with a price per box or per area, plus any optional additional material costs, for a material cost estimate.
Divide your purchase area by the coverage area of one box, and round up to a whole number of boxes.
This calculation works the same way for hardwood, laminate, vinyl plank (LVP) and tile flooring - only the coverage per box changes, and that figure is specific to each product and printed on its packaging.
Layout selection shows guidance only - it does not automatically change your waste percentage. A straightforward straight/parallel layout typically needs a modest waste allowance, while diagonal, herringbone, chevron or complex/many-cut layouts often involve more offcuts and commonly use a higher allowance. Choose the allowance recommended for your specific product and room.
If you enter your plank or tile's length and width, this calculator also shows an approximate area-based piece count (purchase area ÷ one piece's area). This is a reference estimate only - order quantity should be based on whole boxes/product packaging, not this piece count. If you also enter pieces per box, you'll see total pieces supplied versus approximately required and spare; note that piece-count comparison may not apply to mixed-length hardwood packs.
Choose price per box or price per area. Price per box multiplies your box price by the boxes-to-purchase count. Price per area shows both a net-area cost and a waste-adjusted planning-area cost - useful since stores that sell only full boxes may charge a different actual total. Optional underlayment, accessory/trim and other material costs are added separately; installation labour is never included automatically.
Metric. A 30 m² room with a flooring box covering 2.2 m² and 10% waste: additional allowance area = 3.00 m², purchase area = 33.00 m², needing CEILING(33 ÷ 2.2) = 15 boxes.
Imperial. A 100 ft² room with 48in × 6in planks and 0% waste: purchase area = 100 ft², one plank ≈ 2 ft², giving 50 approximate pieces. At 10% waste, purchase area = 110 ft², giving 55 approximate pieces.
The most common mistake is using a generic waste percentage regardless of layout - a diagonal or herringbone pattern often needs meaningfully more waste allowance than a simple straight-laid rectangular room. Another frequent error is calculating an irregular or L-shaped room as a single rectangle instead of splitting it into rectangular sections and adding them together (or using the room-dimensions mode above), which can significantly under- or overstate the true area. It's also worth double-checking that the "coverage per box" figure used is for your specific product, since it varies meaningfully between brands and even between product lines from the same brand.
This calculator estimates flooring material quantity from the area and product coverage you enter. It does not determine subfloor suitability, moisture suitability, joist load/span, structural capacity, expansion-gap requirements, adhesive selection, underlayment requirement, installation method, or building-code compliance, and it does not cover floor refinishing or radiant floor heating systems. Coverage figures must come from your specific product's label, since they vary by brand. Follow your flooring manufacturer's installation guide, and confirm your requirements with a qualified professional before purchasing.
Divide your purchase area (net area plus waste allowance) by the coverage area printed on one box of your specific product, and round up. Coverage per box varies by brand, plank/tile size and product line, so use the figure from your product's label. Use the tab above for an automatic count.
A common planning range is 5-10% for a straightforward straight/parallel layout, and higher (commonly 15-20%) for diagonal, herringbone or chevron layouts, or rooms with lots of cuts around corners, closets or fixtures. The Layout selector above shows guidance only - waste % stays a separate, independently editable field. Check your product's installation guide for its own recommendation.
Multiply the room's length by its width for a simple rectangular room. For L-shaped or irregular rooms, split the space into rectangles and add them together - switch the Area input method above to "Calculate from room dimensions" to add multiple rectangular sections and have them summed automatically.
The calculation method (purchase area ÷ coverage per box) is the same for hardwood, laminate, vinyl plank/LVP, and tile flooring - what differs is the coverage per box, which is specific to each product and printed on its packaging. Flooring type is used for result labelling and context, not to change coverage automatically.
Enter your plank or tile's length and width on the tab above for an approximate area-based piece count (purchase area ÷ one plank's area). This is a reference estimate only - order quantity should be based on whole boxes/product packaging, since boxes contain a fixed number of full pieces and partial boxes generally aren't sold.
Material cost depends on flooring type, quality tier and local prices. Use the Cost tab above with a price per box or per area, plus any optional underlayment, accessory/trim or other material costs, for an estimate specific to your project; installation labour is priced separately.
No - it estimates new flooring material quantity from area and box coverage. Refinishing existing floors and radiant floor heating systems are priced and estimated differently and aren't covered by this tool.
No - it estimates flooring material quantity only. It does not check subfloor suitability, joist load/span, structural capacity, or building-code compliance - confirm those separately, including with a qualified professional if you have concerns.
