Calculate laminate flooring cartons needed from your area and a carton's sqft coverage.
14
Click-lock laminate is sold in cartons rated by sqft coverage, and typically wastes less material during installation than solid hardwood -- so this calculator uses a lower standard waste rate (10%, versus hardwood's 15%) reflecting laminate's simpler, more forgiving installation.
Enter your floor area, your specific product's sqft-per-carton coverage (check the carton label), and a waste factor.
Cartons Needed = (Area ÷ Sqft per Carton) × (1 + Waste Factor), rounded up
For solid hardwood sold by individual board dimensions rather than carton coverage, use the Hardwood Flooring Calculator instead, which applies hardwood's higher standard waste rate.
A laminate carton label typically lists the number of planks, the coverage in square feet, and the plank dimensions. The coverage number is the one this calculator needs. Some retailers also list coverage in square meters, so make sure you enter square feet if your area is in square feet. If the label gives only the number of planks and their dimensions, multiply length by width in feet for one plank, then multiply by the planks per carton to get the coverage.
Suppose you are covering a bedroom and a hallway totaling 210 square feet, and the product is rated at 20.5 square feet per carton, with 10 percent waste (hypothetical values). Raw cartons are 210 divided by 20.5, or 10.24. Adding waste gives 11.27, so you would buy 12 cartons. With 12 cartons you would have about 246 square feet in total, which leaves roughly 36 square feet beyond the room's area. That surplus is helpful for the last row and for future repairs.
Many laminate floors float over an underlayment that provides a slight cushion, sound dampening, and, depending on the product, a moisture barrier. Some laminates have underlayment already attached. Concrete subfloors often need a separate vapor barrier, and the manufacturer's instructions specify what is acceptable. Underlayment is sold by area in rolls, so your floor area with a small overlap allowance is the figure to use, not the number of laminate cartons.
The calculator gives a carton count for a single product and area. It does not price the job, calculate trim or transitions, or account for subfloor repairs. Buying one extra carton is a common practice, because matching a discontinued laminate years later can be hard.
Click-lock laminate installation is generally simpler and generates fewer offcuts than solid hardwood's staggered-joint, grain-matched installation.
Most laminate requires a separate underlayment layer (unless pre-attached) -- that's priced and purchased separately from the laminate cartons themselves.
You can, since the formula is the same when a product is sold by cartons with a listed coverage, though the standard waste rate is set for laminate, so adjust it as needed.
The carton label lists how many planks it contains. Multiply your carton count by that number to see the total planks you will have.
Some products can be installed over certain existing surfaces, but it depends on the manufacturer's instructions and the condition of the floor, so check both before deciding.
No. It is a common default for simple rectangular rooms. Rooms with many cuts, diagonal layouts, or narrow spaces usually need more.
