Laminate for a 5 × 5 m room, by waste allowance
The floor is 25 m². How much extra you buy depends on the layout: a straight lay in a plain rectangle wastes less than a diagonal lay or a room with lots of cuts. The last column is the area you will actually pay for, in whole packs of 2.22 m².
| Waste allowance | Flooring needed (m²) | Packs | m² you buy |
|---|---|---|---|
| 5% | 26.25 | 12 | 26.64 |
| 8% | 27.00 | 13 | 28.86 |
| 10% | 27.50 | 13 | 28.86 |
| 15% | 28.75 | 13 | 28.86 |

About a 5 × 5 m room
This size is typical of a large living room or an open kitchen and dining space. You also need underlay (2 rolls of 15 m²), about 19.2 m of beading or scotia, and an expansion gap of about 10 mm around the walls. The skirting board calculator and the carpet calculator are useful if you are changing the rest of the room.
