Square footage calculator
Measure a room or whole area in square feet — including L-shaped rooms — and route it into a project planner.
Enter one or more areas. For L-shaped rooms, split the room into rectangles.
Add your areas and dimensions to get square footage, then route it into a planner.
How to use it
Enter each rectangle's length and width. For an L-shaped room, split it into two rectangles and add them. The result feeds into the flooring, painting and landscaping planners.
- Split any irregular shape into rectangles.
- Add each area to the list.
- Use the buttons to carry the area into a planner.
These estimates are based on state-level averages, not ZIP-level precision. The final cost varies with your home and local market.
