Understanding how to calculate square footage is essential for construction, renovation, and property assessment. Below are the formulas and tips for calculating area for different shapes.
Formula: Length × Width
Multiply the length by the width to get the area. This is the most common shape for rooms and buildings.
Formula: π × Radius²
Multiply pi (3.14159) by the radius squared. Used for circular rooms, gardens, and features.
Formula: Side × Side
Multiply one side by itself. All sides are equal in a square.
Formula: ½ × Base × Height
Multiply the base by the height and divide by 2. Common in roofing and landscaping.
Always add 5-10% extra for waste
Materials like flooring, tiles, and paint require extra for cuts and mistakes. The waste factor helps you order enough.
