Estimates
Room plan
Walk clockwise round the room and enter each wall’s length with the inside angle at the corner where it ends. The plan, area and carpet estimate update as you type.
Wall lengthAngle at end (°)
Use 90° for a normal corner and 270° where the room steps out, such as the inner corner of an L-shape. Other angles work for bays and angled walls. The last wall’s angle is the corner back at the start.
