Square Footage Calculator: Easily Calculate Area Online

Intro

Whether you’re buying flooring, painting walls, planning landscaping, or estimating construction materials, knowing the exact area of a space is essential. A Square Footage Calculator online is the perfect tool to quickly determine the area of any room, wall, or surface without complicated math. It helps homeowners, real estate agents, contractors, and DIY enthusiasts calculate square footage easily and accurately.

Formula / Working

The calculator works by applying basic area formulas depending on the shape:

1. Square or Rectangle:

Area=Length×Width\text{Area} = \text{Length} \times \text{Width}Area=Length×Width

2. Triangle:

Area=12×Base×Height\text{Area} = \frac{1}{2} \times \text{Base} \times \text{Height}Area=21​×Base×Height

3. Circle:

Area=π×r2\text{Area} = \pi \times r^2Area=π×r2

4. Complex Shapes:
   Divide the shape into smaller rectangles/triangles, calculate each area, and then add them together.

The Square Footage Calculator online automates this process—just enter your measurements, and it instantly returns the total area in square feet (and often other units like square meters).

Step-by-Step Usage

Here’s how to use the Square Footage Calculator:

1. Select the shape of your space (rectangle, triangle, or circle).
2. Enter the required measurements (length, width, radius, or base/height).
3. Click Calculate to get the square footage.
4. Use the result for flooring, painting, or material estimation.

Examples

Example 1: Rectangle Room

• Length = 20 ft, Width = 15 ft

Area=20×15=300 sq ft\text{Area} = 20 \times 15 = 300 \, \text{sq ft}Area=20×15=300sq ft

✅ Result: The room is 300 sq ft.

Example 2: Circular Garden

• Radius = 10 ft

Area=π×102=3.1416×100=314.16 sq ft\text{Area} = \pi \times 10^2 = 3.1416 \times 100 = 314.16 \, \text{sq ft}Area=π×102=3.1416×100=314.16sq ft

✅ Result: The garden covers 314.16 sq ft.

Example 3: Triangular Plot

• Base = 30 ft, Height = 20 ft

Area=12×30×20=300 sq ft\text{Area} = \frac{1}{2} \times 30 \times 20 = 300 \, \text{sq ft}Area=21​×30×20=300sq ft

✅ Result: The triangular plot is 300 sq ft.
