**What Is a Square Foot?**

A square foot is a unit used to measure Area. It is nothing but the Area inside a square that helps to measure the foot per side, length multiplied by breadth is Area.

**How Do You Calculate Square Footage?**

Most of the home project be it wallpaper or landscaping begins with the correct measurement. To measure the square foot of the Area, all you need is measuring tape and a method for recording the measurement. The steps of the measurement are.

- Measure the length of side of the room which is the longest and measure it in a straight line.
- Check the length
- Now measure the length of the shortest side of the room and then measure all the four sides if it’s square space.
- Check out the area’s width
- Multiplication of the length and the breadth measure to get square feet

### **Calculation of the Square Footage of these Various Shapes **

Calculating the square foot of any space is very easy all you need to know is the formula for it here they are

**Rectangular and Square Spaces**

The formula for Area of rectangle and square = l (length)x w(width)

**Circular Spaces**

The formula of Area for circular space = πr2(radius)

The distance from the midpoint of the space of the circle to its edge. Radius is the measure of the straight line which passes through the centre of the circle.

The value of the pi is 3.14

**Triangular Spaces**

The formula for Area of triangular space. = ½ b(breadth)h(heights)

This formula works for the right-angle triangle (it has a 90-degree angle). To measure the surface properly, if your Area is not a right-angle triangle, break it into one. For every right-angle triangle, multiply the base and the height and divide it by two for total square footage to add the value.

**Calculate Square Footage of Spaces with Odd Dimensions**

If the Area you are measuring is not a neat geometric shape, divide the Area into smaller shapes to get an accurate measurement. Add all the values to get the total Area. For e.g., if your kitchen is rectangular, you can measure the nook and central part of the room separately to get the actual square footage.

First, all you have to do is find the length and width of each section:

Main room measurement

10 feet x 12 feet = 120 square feet

Nook measurement –

6 feet x 4 feet = 24 square feet

Then, add these two values together:

24 square feet + 120 square feet = 144 square feet

**How to Calculate Square Footage of Material to Adjust for Waste**?

After cutting wallpaper tiles and other materials, odd pieces are left behind that cannot be used further. Measuring wastage becomes very important as scarcity of the material can happen, and the project will not be finished on time. In order to avoid scarcity of material, the best thing is to order 5-10% of the extra material.

** Calculate Square Footage of a Whole House**

The square footage of the home can be calculated by including livable, finished areas. You will indeed not calculate an unfinished basement garage or attic. Outbuildings are also not measured. The things which should be included in the measurement are the closet, stairwells, and hallways.

Measure each room or Area individually, e.g. like this

Measurement of Bedroom 1:

12 feet x 10 feet = 120 square feet

Measurement of Bedroom 2:

12 feet x 10 feet = 120 square feet

Measurement of Living room:

15 feet x 12 feet = 180 square feet

Measurement of Bathroom: **feet to square feet** ( the length and breadth are in feet, but when multiplied, we get Area which is in square feet)

7 feet x 5 feet = 35 square feet

Measurement of Kitchen:

12 feet x 10 feet = 120 square feet

Measurement Dining room:

10 feet by 10 ft = 100 square feet

Measurement of Front Hall:

4 feet by 10 feet = 40 square feet

Measurement Closet:

1 foot by 5 feet = 5 square feet

Add all the calculated values tighter here; in this case, this house is 720 square feet.

**Convert Inches to Feet**

For some projects, you would be required to convert inches to feet; hence you must know this anyone can do. It’s simple. All you need to do is divide the inched by 12(for converting inches to feet). For converting from feet to inch, multiply inches by 12.

**Other units of measure**

To convert square footage area into yards which is comm, divide the width and length measurement by 3(one-yard consist of 3 meters)

For calculating the Area in square meters used mainly for the metric system, divide the width and length by 0.3 as one foot consists of 0.3 meters.

**What is the usable square footage?**

** **Usable square footage this term is used in real state settings to give an idea about the measurement of the usable square footage, excluding areas like hallways, stairwells and lobbies.

**WHAT ARE GROSS SQUARE FEET?**

**How to calculate gross square feet (GSF)**

It refers to the measure of the total enclosed area of the building from exterior walls. Its is used as a term for describing all Area in the facility. GSF is used for budgeting, planning for operation construction, and maintenance. It is an essential metric for maintenance and operations.

**Calculate Gross Square Footage**

If calculating gross square footage is very easy. All you need to do is calculate the exterior dimension of the building. Measure the width and length of the building walls. Multiply the width and height in order to find the square footage. If your building has more than one floor, don’t forget to multiply the square footage by the number of the floors

**WHAT IS NET SQUARE FEET?**

**How to calculate net square feet (NSF)**

Net square feet is obtained by subtracting areas that are inaccessible to people from the gross square feet. The NSF would include Area that people can walk for eh classroom, office, stairwell, hallways and closets. It would not consist of space taken up by mechanical chases closed off between floor or walls

NSF comes in handy to measure the Area during capital planning for renovation, determining circulation and mechanical area locations. NSF can be time-consuming and is not available readily in most facilities. The spec management software is an excellent alternative to measure accurately.

**Calculate Net Square Feet**

Measure the building gross square footage area and subtract it from accessible space like mechanical Area and wall. The value obtained will be net square feet. The other method to calculate the net square feet, i.e., by adding the Area of every room in the building or flat

**WHAT IS NET ASSIGNABLE SQUARE FEET?**

It is the sum of the measure of all the Areas assigned to the person (occupant) for specific use. Some examples of the assignable spaces include laboratories, classrooms, study areas, offices, and general use rooms. Residential areas, unique use rooms. People gather to accomplish a task in these areas.

The net assignable areas include the Area in which the occupant can make such a task which help them to accomplish the mission of the organisation. The areas which will not involve in net assignable areas are elevator shaft, stairwell, closets etc. as there are areas are not assigned for the use of occupant, they are not included in NASF

The department can be allocated the best space for working if the accurate measurement of NASF is known. NASF helps to access the revenue for leased Areas. It also helps determine the staff needed for a particular area so that there is no wastage of Area.

So now you know how to calculate the square footage area of various geometric regions. Now you might be confident before going ahead with any project s you know multiple metrics. Hope you enjoyed reading it, and the article was helpful.
