Flooring Calculator Homebase
To use the calculator you'll need your home's external floor area for both upstairs and downstairs. To find the ground floor area: go outside, measure the length and width of the downstairs walls and multiply these two figures together. If the upstairs is identical to the downstairs, simply double the ground floor area. If different, calculate the upstairs area separately and add it to the downstairs result.
