Flooring Calculator

Flooring Calculator works out how many boxes of laminate, vinyl plank, engineered wood or other boxed flooring to buy for a room. Enter the floor’s length and width, or its area, in feet or metres. Ten per cent is added for wastage — the offcuts at the end of each row, cuts around doorways and the odd damaged plank — which suits a straight layout in an ordinary room; allow 15% for a diagonal or herringbone layout or a room with many corners. Enter the area one box covers, printed on the box or the product page, and it rounds up to whole boxes, since boxes are sold whole, and shows how much floor those boxes actually hold. Add the price, per square foot, per square metre or per box, and it works out the cost, to the paisa. Order every box from one batch, as colour and texture can differ between batches, and keep the spare planks for repairs.

1. Choose feet or metres, and enter the floor.
2. Enter the area per box and check the wastage.
3. Add the price if you want the cost.
4. Read the boxes to buy and the area they cover.

• Skirting, underlay, transition strips and labour are not included.
• The area per box and the price must be in the same unit as the floor (square feet or square metres).
• Everything is worked out in your browser. Nothing is sent anywhere.

About 10% for a straight layout and 15% for diagonal or herringbone, and more for rooms with many corners.

It is printed on the box and the product page, for example 21.5 sq ft or 2 m² per box.

No. Underlay is usually sold by the roll for the floor area itself, with little wastage.

Shops sell flooring by the box, and it is better to have a few spare planks than to run short mid-room.
