Work out how many rubber gym tiles or mats you need for your home gym, garage gym, garden room or PT studio.
How much gym flooring do I need?
To calculate gym flooring, multiply your room length by your room width to get the total square metres. Then divide that number by the size of each tile or mat.
For most home gyms, it is smart to add a small waste allowance for cutting, edges and awkward room shapes.
