How can painter's tape help in planning living room furniture layout?

Using painter's tape on the floor allows you to map out sofa and furniture dimensions virtually before moving actual pieces. Marking the size and placement of sofas, chairs, and rugs helps visualize traffic flow and seating zones. This simple technique prevents guesswork, ensures optimal thirty to thirty-six inch walkway clearance, and reduces layout mistakes. Testing your living room with painter's tape can improve comfort and minimize costly furniture returns.
