Help Measuring
Working out the quantity of flooring you need is really dependant on the layout of your room.
Rectangular rooms can be calculated easily by multiplying the length by width. If your room is L-shaped, or has alcoves or bay windows, you need to divide your room into separate smaller areas, adding these together to come to your final quantity. Don’t forget to add at least 10% to your final quantity for any wastage.
