How do I calculate square footage of a room?

Measure the length and width of the room in feet, then multiply them together. For example, a room that is 15 ft long and 12 ft wide has an area of 15 × 12 = 180 sq ft. For irregular rooms, split the space into rectangles, calculate each one, and add the results.

How do I convert square meters to square feet?

Multiply the area in square meters by 10.764. For example, 100 sq m × 10.764 = 1,076.4 sq ft. To go the other way, divide the square footage by 10.764 to get square meters.

How many square feet are in an acre?

One acre equals exactly 43,560 square feet. This conversion is commonly used in land measurement and real estate when dealing with larger properties and plots.

How do I convert square inches to square feet?

Divide the area in square inches by 144 (since 1 ft = 12 in, and 12 × 12 = 144 sq in per sq ft). Alternatively, multiply by 0.00694. For example, 288 sq in ÷ 144 = 2 sq ft.

What is price per square foot and how is it calculated?

Price per square foot is the total cost of a property divided by its total area in square feet. For example, a 1,200 sq ft home priced at $240,000 has a price of $200 per sq ft. It is a useful metric for comparing properties of different sizes fairly.

What is a typical room size in square feet?

A small bedroom is typically around 100–120 sq ft, a standard bedroom is 130–170 sq ft, and a master bedroom can be 200–300 sq ft. Living rooms average 200–400 sq ft, and a full family home in the US typically ranges from 500 to over 2,000 sq ft.

Is a board foot the same as a square foot?

No. A square foot is a unit of area (two-dimensional), while a board foot is a unit of volume used specifically for lumber — it equals 1 ft × 1 ft × 1 inch thick. The two units measure different things and cannot be directly converted.

Complete User Guide

Our Square Footage Calculator makes area measurement simple. Here's how to use it:

Step 1: Enter the length of the room or area in feet.

Step 2: Enter the width of the room or area in feet.

Step 3: Optionally enter the number of identical rooms/areas if you are calculating for multiple spaces.

Step 4: Click 'Calculate' to see the total area in square feet and square meters.

For unit conversions (e.g., square meters to square feet), simply enter the area in your preferred unit and the calculator will convert it automatically.

The Mathematical Formula

Area = Length (ft) × Width (ft)

Area of a rectangle:

Square Footage = Length (ft) × Width (ft)

For multiple rooms: Total Area = Square Footage × Quantity

Common unit conversions: - 1 sq meter = 10.764 sq ft - 1 acre = 43,560 sq ft - 1 sq inch = 0.00694 sq ft

Example: A room that is 12 ft long and 10 ft wide has an area of 12 × 10 = 120 sq ft.

About Square Footage Calculator

A square foot (sq ft) is an imperial unit of area widely used in the United States, Canada, the United Kingdom, and several other countries. It represents the area of a square with sides measuring exactly one foot. Despite the global shift toward the metric system, square footage remains the standard language of real estate, interior design, and construction in these regions.

Knowing the square footage of a space is useful in many everyday situations. When buying or renting a home, square footage determines the price per square foot — a key metric for comparing properties of different sizes and locations. When painting a room, the area tells you how much paint to buy. When laying flooring, carpet, or tiles, it tells you how many materials to order. Even planning furniture arrangements benefits from knowing the exact square footage available.

For simple rectangular rooms, calculating area is as straightforward as multiplying length by width. For more complex floor plans — rooms with alcoves, L-shapes, or bay windows — the best approach is to divide the space into smaller rectangular or square sections, calculate each section individually, and add the results together.

Unit Conversions at a Glance: If you already know the area in another unit, you can convert it quickly. Multiply square meters by 10.764 to get square feet. Multiply acres by 43,560. Multiply square inches by 0.00694. Working backwards is equally straightforward — divide your square footage by the same factor to convert to the target unit.

Square Footage Pricing: Once you know the area, you can also calculate price per square foot by dividing the total cost of a property by its total square footage. This makes it much easier to compare real estate options on an equal footing, regardless of their absolute size or price.
