Knowing how to calculate square feet is a skill. Yes, you heard it right! It would help if you had it from flooring work to other projects. Square foot calculation is essential to know the suitable materials.

Are you buying or selling a house? You must know the square feet calculation. Square footage of a house is crucial. It determines the price point of the house. It allows you to understand the possible renovations in the future. Besides, it will enable you to know tax amounts for the house you live in.

## So how do you calculate square feet?

You are capable of calculating footage of a single room. Just use a measuring tape. A laser measure may provide more accuracy. You get the width and length from this. Now multiply the length by width. Done! You have it. The square footage of your house is now at your fingertips.

For instance, a room is 20 feet wide. The length is 13 feet wide. Now multiplying the numbers gives 260 square feet.

Let’s get into the details of the measurements.

Start by measuring the area. First, find the dimensions of the space. It would help if you had the length and width to find the area of your room. The longest side of the area will be the length. Now fix the length of measuring tape on one side. Extend to the other side of the wall you measure.

Keep a recording of the measurement. The shortest side will be the width. Repeat the procedure. Re-record it.

Now apply the formula of square footage. It is length x width = area. The resultant area will be in square feet.

But what about the weird-looking spaces? Sometimes you may come across some odd dimensions. These are the extra spaces present in separate areas.

How to calculate these places? Simple. Try to divide the spaces into sections. Now measure each section separately. Then calculate separate square footages of the spaces. Next, add the values. The resultant value is the total square feet of the area.

Let us assume an area. Supposing, it is rectangular. And it has a nook. Follow the picture shown below. Find the length and width of each section. Now calculate the square feet of each section. Follow the formula mentioned above.

Now do the addition of the values. You will get the final area in square feet. In this case, it is 141 sq. ft.

Now you know the number of materials required for the project. Let’s focus on adjusting the waste amount. Mistakes may occur at any time. Be it in calculations or measurements. As a result, you end up buying more than you wanted. Accidents are unforeseen. You may end up breaking apart. Or you may spill a limited amount of paint. In worst cases, the colors may be unavailable in an emergency.

Now you are left scrambling for more materials. What do you do in this situation? Always try to get five percent or ten percent more. Keeping an additional amount keeps you covered. In case of accidental damages, you won’t have to suffer. Now you can finish your work at peace.

### Calculating the square foot of the entire home

The measurement of a single room is not a big deal. A couple of rooms to calculate can get messy. Calculating the entire home is too much at times. Mario Mazzamuto said a room is a simple collection of boxes.

Divide the houses into sections. Suppose the house has a bedroom, living room, bathroom, kitchen, and a hallway. The assumed values are shown in the picture. Use the formula of square footage. Now add all of them. You will find the resultant square feet of the whole house.

A kitchen or a room may not be the same shape as others. Use the vCals handy calculator. Put down the shape of the room. Eventually, the calculator will prompt the measurements.

Use the ancient method. Measure using a grain of salt.

Surprisingly, square feet measurement is relatively subjective. You might have measured the interior walls. The square footage is measured there. Many architects use their methods of calculation. Here they calculate using the exterior walls.

This proves the discrepancies. Many times the measurements of real estate agents, builders, and so do not match. They are different from calculations using interior walls. Generally, the measure extends through the exterior wall framing. Now six inches are added to each measurement. This is how the values differ.

#### Conclusion

Now you know how to calculate square feet. Use the formula every time to calculate. Add the values to get the final square feet of the house. Keep measuring!
