Here are some simple steps to calculate the square footage of your bedroom.Step 1: Measure the Length and Width of Your RoomUse a measuring tape to measure the length and width of your room in feet. Make sure to measure from the baseboard, not from the edge of your carpet or other flooring. Write down the measurements for each wall.Step 2: Multiply the Length and WidthMultiply the length and width for each wall to get the square footage for that wall. For example, if your room is 12 feet long and 10 feet wide, the square footage for that wall would be 120 square feet (12 x 10 = 120).Step 3: Add Up the Square FootageAdd up the square footage for each wall to get the total square footage of your bedroom. For instance, if you have four walls that are 120 square feet each, your bedroom would be 480 square feet (120 + 120 + 120 + 120 = 480).Tips:When measuring, be sure to account for any alcoves, closets, or other areas that aren't part of the main rectangular space of your bedroom. To get a more accurate measurement, you may want to measure each wall in multiple places and take the average.Ready to start designing your dream bedroom?
