Measuring floor space and estimating the amount of flooring is a skill. Once you have chosen a style and colour, your local carpet retailer will come and measure your home accurately. This will give you the exact amount of carpet you require and will ensure that your house is carpeted in the most cost effective manner. But before you visit a flooring retailer it’s a good idea to measure approximately how much carpet you need. Carpet is usually sold in square metres, so by calculating the area you require, you’ll know how much you can afford or what style of carpet fits your budget.
