Order the Flooring. Determine the number of boxes you need before ordering your laminate flooring. Each box of flooring should include a notation of the total square footage it covers. One box of flooring may cover 30 square feet. Divide this number into the total square footage of the area you plan to cover. For example, if you have a total of 550 square feet, including waste, divided by 30 equals just over 18 boxes.
