Flooring for a 10 × 11 ft room (110 ft²)
Box counts depend on how much each box holds, which is printed on the box (20 to 25 ft² is common for laminate and vinyl plank).
| Layout and waste | Flooring to buy | Boxes at 20 ft² | Boxes at 24 ft² | Boxes at 30 ft² |
|---|---|---|---|---|
| 5% (Straight, simple room) | 115.5 ft² | 6 | 5 | 4 |
| 7% (Typical room) | 117.7 ft² | 6 | 5 | 4 |
| 10% (Diagonal or many cuts) | 121.0 ft² | 7 | 6 | 5 |
| 15% (Herringbone or patterns) | 126.5 ft² | 7 | 6 | 5 |
Before you buy
Measure into doorways and closets, and buy one extra box for future repairs, since dye lots vary. Let the flooring acclimate in the room for as long as the maker says. See the waste factors guide.
Laying it out: rows and the last row
Planks usually run along the long wall (11 ft here), so they stack up across the 10 ft side, which is 120 inches. A last row that is only a sliver looks bad and can lift, so check it before you start. With 48 inch planks you need about 3 planks per row.
| Plank width | Rows across | Width of the last row | Check |
|---|---|---|---|
| 5 in plank | 24 | 0.0 in | No sliver |
| 7 in plank | 18 | 1.0 in | Too thin: trim the first row |
| 9 in plank | 14 | 3.0 in | Fine |
If the last row comes out under 2 inches, cut the first row narrower so that the first and last rows are about the same. Leave the expansion gap the maker specifies (usually about 1/4 to 1/2 inch) around the walls.
A 10 × 11 room: the odd foot makes an odd last row
A 10 × 11 ft room has 110 sq ft of floor and needs 121.0 sq ft with 10% waste, which is 7 boxes at 20 sq ft a box or 6 at 24 sq ft.
Rooms sold as 10 × 11 are rarely exact. Measure at both ends of each wall, use the larger figure, and check the last-row table above against your own plank width before you start. The 10% order is only just over a whole number of 20 sq ft boxes, so a plain straight layout at the 5% or 7% line needs one box fewer; open the last box only if you have to, so it can go back. The distance around the room is 42 ft, which is also your quarter round or baseboard length before the doorway comes off.
