What is square footage?

The Square Footage Calculator estimates the square footage of a lot, house, or other surfaces in several common shapes. If the surface is complex in shape, it may be possible to section the surface into simple shapes and add their square footages together.

What is Meant by Square Footage?

In mathematics, square footage is the measurement to calculate the area. The area is generally measured for any two-dimensional shapes that contain the set of lines. To find the square footage, simply multiply the length and width.

Formulas to calculate square footage:

Formulas to calculate square footage will depend upon the shape of which we are calculating the area or square footage. Following are some formulas:

How do I convert square meters to square feet?

We might want to know how big a 100 m2 (square meter) expressed in sq ft is. In other words, we would want to convert from sq m to sq ft and find out the square footage of that house, which is:

100 sq.m. × 10.764 sq ft/sq.m. = 1076.391 sq ft.

How do I convert acres to sq ft?

The procedure for converting square inches to square feet or from acres to sq ft is the same as converting from square meters to square feet. In the following examples, you will find the most common of these conversions: how many square feet are in an acre.

1 acre × 43 560 sq ft/acre = 43 560 sq ft
30 sq in × 0.00694 sq ft/sq in = 0.208333 sq ft

Calculations for ‘L’ shaped rooms or areas:

To calculate the square feet of an ‘L’ shaped room or area, divide the shape up into rectangular sections and treat each one as a separate area for calculation. You can then add the totals together at the end.

How to calculate square footage in different types of rooms?

Rectangular rooms: To calculate the area of a room or area with a square or rectangle shape, simply follow the formula.
Rooms with closets: Rooms with closets are like rectangular rooms with small rectangular add ons. Calculate the square footage of each rectangle, and add them together.
Odd-shaped rooms: The standard tool for area measure is something you can apply even to odd-shaped rooms. All you need to do is break the room down into separate areas that are easy to calculate on their own and then add up the results. If your room has a lot of angles, use this formula for a triangle—it’s just a rectangle or square cut in half!
Length (in feet) x width (in feet) ÷ 2 = area in sq ft
