To know how much carpet you need, measure the room or area extending into the doorways. It is usually easier to “round up” inches to the next foot. If the area is irregular, divide it into squares or rectangles and measure each area and then add all of your squares together for your total. See our Carpet Buying Guide’s carpet estimator diagram below for calculation instructions.
After you total your square footage, be sure to add 10% to your total for “waste”. See the carpet estimator diagram below for calculation instructions.
To estimate the total cost for your carpet, multiply the total number of sq. ft. (remember to add the 10% for waste) by the carpet price per square foot. Note that padding and installation are added on top of your carpet’s per square foot price. Click Here for a detailed view of the diagram below.
