🙋 What Is Square Footage?
Square footage is a measure of area — it tells you how much flat space a room covers. It’s measured in square feet (sq ft or ft²).
So if a room is 10 feet wide and 12 feet long, its area is:
10 × 12 = 120 square feetThat’s it!
🧮 The Basic Formula
Here’s the super simple formula for a square or rectangular room:
Square Feet = Length × WidthJust make sure both measurements are in feet. If you measured in inches, convert to feet first by dividing by 12.
📋 Example 1: Rectangular Room
Room dimensions:
- Length = 14 feet
- Width = 11 feet
Square Feet = 14 × 11 = 154 sq ftSo that room is 154 square feet in area.
📐 Example 2: L-Shaped Room
If your room has two connected rectangles (like an L shape), break it into two parts.
Section A: 10 ft × 12 ft = 120 sq ft
Section B: 6 ft × 4 ft = 24 sq ft
Add both:
120 + 24 = 144 sq ftThe total area is 144 square feet.
