How to Calculate Flooring Quantity
The key to accurate flooring estimates is adding a waste factor on top of your room's square footage. The waste accounts for cuts at walls, pattern alignment, and the unusable offcuts from diagonal runs. Standard rooms use 5โ10%; complex layouts use 10โ15%.
For sheet vinyl, the roll width and length determine how many rolls you need. For hardwood or laminate planks, each plank's width ร length gives you coverage per plank. Always buy a little extra โ you'll need matching material for future repairs.
