How to calculate square feet of a room?

Understanding how to calculate square footage is a vital skill for the majority of home renovation jobs. Square footage is a crucial statistic to get the proper quantity of materials for your project, from flooring and painting to landscaping. Accurate measurements of square footage are helpful both while purchasing and selling homes.

How do you calculate square feet of a house?

Start with a few basic supplies while getting ready to measure the square footage of a house, condo, or townhouse:

• Pencil and paper

• Calculator

• Measuring tape

If the property is a perfect rectangle, you only need to measure the length and width and multiply those two numbers together. For instance, your property would be 2,400 square feet if your one-story house was 60 feet wide by 40 feet long (60 x 40 = 2,400).

The majority of properties have more intricate floor designs, though. In this situation, it's beneficial to measure square footage by using these straightforward procedures;

• Label every room you need to measure on a rough drawing of your complete space. Include hallways and vestibules in your definition of a "room."

• Each room's length and width should be measured in feet. To determine the square footage of that room, multiply the length by the breadth. For instance, a bedroom measuring 12 feet by 20 feet has a square footage of 240 (12 × 20 = 240). Write the total square footage of each room in the area provided on your drawing.

• Add together the measurements from each room to get the overall square footage of your house.

I hope this helps you with how to find square footage.

When I was redoing my living room, I needed to figure out how much flooring I’d need, but I had no clue how to measure square footage of a room. I asked my dad to show me, and turns out, it was easier than I thought. Now I can do it on my own. Here’s what I learned.

How Do You find The Square Footage of a Room?

• I grabbed a measuring tape and measured the length of the room. I made sure to go from one wall to the other and wrote it down. 

• Then, I measured the width of the room, again from wall to wall, and noted that too. 

• Once I had both numbers, it was just simple multiplication. I multiplied the length by the width, and that gave me the square footage.

For example, my living room was 12 feet long and 10 feet wide, multiplying 12 by 10 gave me 120 square feet. That’s the area of the room.

I also found out that if the room isn’t a perfect rectangle or square, you can break it into smaller sections, measure each section, and add up the square footage of each part. It’s not hard, and it’s something I feel confident doing now. 

It really helped me figure out how much material I’d need for the floor without guessing. This is how to determine square feet of a room.

Measurement and calculation of the square footage of an odd-shaped room:

It’s common to have rooms that may have an open floor plan with several odd-shaped spaces, built-ins, nooks, or closets. For those rooms, all you have to do is to divide your space into even shapes, (rectangles or squares) and then just use the formula given above. After that, just add all the individual spaces you just calculated together.

For instance, the main section of a room measures 10 ft. by 10 ft., and an additional space of the room measures 5 ft. by 6 ft. To calculate the square footage of this irregular-shaped room, you need to find the square footage of both the main section and the small section of the room and then add them together:

Square Footage of Main Section:

10 x 10 = 100 sq. ft.

Square Footage of Small Section

5 x 6 = 30 sq. ft.

Total Square Footage of the Irregular Room = 100 + 30 = 130 sq. ft.

I hope now you know how to calculate sq ft of a room.
