Calculate area for multiple shapes and get the total
Our Square Footage Calculator computes the area of multiple shapes (rectangle, circle, triangle, trapezoid) and sums them for a total. Results are shown in both square feet and square meters. An optional cost estimate lets you calculate material or project costs based on price per square foot.
This tool is ideal for flooring estimates, painting projects, landscaping, HVAC sizing, and any project where you need to measure total area across irregular spaces.
Multiply square feet by 0.092903 to get square meters. For example, 500 sq ft × 0.092903 = 46.45 sq m. This calculator automatically shows both units for every area entry.
Costs vary widely by material. Laminate flooring ranges from $2-8/sq ft, hardwood $6-15/sq ft, tile $5-15/sq ft, and carpet $2-7/sq ft installed. Use the cost estimate feature with your local contractor pricing for a quick budget.
