Flooring Calculator
Number of flooring packs.
Explanation
Hardwood, laminate, or vinyl? Calculate the number of boxes needed. The classic mistake is forgetting wastage! ### Wastage (Cuts) You cannot lay flooring without cutting planks at the end of rows. - **Straight Lay**: Add **+5% to +7%**. - **Diagonal Lay**: Add **+15%** (much more waste). - **Complex Room**: Add **+10%**. ### Boxes Flooring is sold in boxes (e.g., 20 sq ft / box). The calculator always rounds up to the next full box. ### Underlayment Don't forget the underlayment (sound/thermal insulation)! You need the same area as the floor.
Examples
- Room 120 sq ft. With 5% waste = 126 sq ft. If box is 20 sq ft, you need 7 boxes (140 sq ft).
- Don't try to buy 'exact', you will always be one plank short!
FAQ
Direction?
Usually parallel to the main light source (window) or along the longest wall to make the room look bigger.
Expansion gap?
YES. Leave 1/4 to 3/8 inch along walls (hidden by baseboards). Wood expands with humidity.
