The provided context does not offer specific instructions on how to measure a sofa for a doorway. However, determining if a sofa will fit involves a straightforward process of measuring both the furniture and all entry points.
First, you will need to measure the sofa's key dimensions. Measure its width from the widest point, typically arm to arm. Next, find the height by measuring from the floor to the highest point of the back. Then, measure the depth from the front edge to the back. A critical measurement is the diagonal depth, which you can find by placing a measuring tape from the top back corner of the frame to the bottom front corner. This diagonal measurement often determines the minimum clearance needed.
After measuring the sofa, you must measure every part of the delivery path. This includes the height and width of all doorways, hallways, and stairwells. For doorways, measure the narrowest part of the opening, which is usually inside the door jamb. Also, be sure to note any potential obstructions along the path, such as low-hanging light fixtures, radiators, or tight corners that could impede movement.
To confirm the fit, the sofa's depth or height should be less than the doorway's width. More importantly, the sofa’s diagonal depth must be less than the doorway's height. This allows delivery personnel to tilt the sofa on its end and pivot it through the opening. If the sofa must navigate a tight turn immediately after the doorway, ensure the hallway's width is greater than the sofa's width or depth to allow for the turn. Remember to account for any non-removable features like fixed legs, and consider that sectional sofas can be moved in individual pieces, which should be measured separately.
