Area Calculator in Feet and Inches
Select the Room (Feet + Inches) or Rectangle (Feet + Inches) shape to enter each dimension exactly how a tape measure reads it — a whole-feet field and a separate inches field. For a wall measuring 10 ft 6 in, enter 10 in the feet field and 6 in the inches field. The calculator converts feet + inches ÷ 12 into decimal feet automatically before computing the area, so no manual conversion is needed.
Leave the inches field at 0 for measurements that land on an exact foot. Results display instantly in square feet, square inches, square yards, square meters, and acres.
