Floating Floor Calculator

A floating floor does not need to be nailed or glued to the subfloor. Instead, the individual planks feature a "click-lock" mechanism that holds them together, allowing the entire floor to rest (or float) on top of the subfloor or underlayment.

You will inevitably have to cut planks to fit the edges of your room, around doorways, and to stagger the joints properly. A 10% waste factor ensures you have enough material to cover these cuts and any accidental mistakes.

Yes, unless your flooring specifies it has a pre-attached underlayment pad. Underlayment is crucial for providing a moisture barrier (especially over concrete), dampening sound, and smoothing minor subfloor imperfections.

Floating floors expand and contract with temperature and humidity changes. You must leave a 1/4" to 1/2" gap between the flooring and all walls/obstacles. This gap is later covered by baseboards or quarter-round molding.

Yes, you can often float a new floor over existing hard surfaces like tile, concrete, or firmly attached vinyl. You cannot install floating floors over plush carpet or heavily damaged/uneven floors.

Break the room down into smaller rectangles. Calculate the length × width for each rectangle separately, add those total square footages together, and use that combined number as your base area.

It varies widely by brand and plank size. Typically, a box of laminate or LVP contains between 15 and 25 square feet. You must check the specific product packaging for this number before calculating.

Basic tools include a tape measure, utility knife, rubber mallet, tapping block, pull bar, and expansion spacers. You will also need a saw (miter saw, circular saw, or jigsaw) to cut the planks.
