## Calculator Use

Use this calculator to find the square footage, square inches, square yardage, square meters or acres for a building, home, garden or construction project. Calculate square footage, inches, yardage, meters and acres for landscape, flooring, carpet, or tiling projects to estimate area and the amount of material you will need. Also calculate the cost of materials when you enter the price per square foot, price per square inch, price per square yard or price per square meter.

Price is entered in the fields, for example, as $ price: 3.00 per: 1 square unit: foot (ft²) meaning $3.00 per 1 square foot or $ price: 25.00 per: 1000 square unit: foot (ft²) meaning $25.00 per 1000 square feet etc ….

If you want to calculate volume of bulk materials such as mulch or gravel you should use our calculator for cubic yards and cubic meters.

Enter measurements in US units or metric units. Calculate area from your measurements in inches (in), feet (ft), yards (yd), millimeters (mm), centimeters (cm), or meters (m). You can also enter decimal values. For example, if you have one measurement that is 7’3" you can enter that as 7.25 feet (3"/12" = 0.25 ft). If you have a measurement of 245 cm you can also enter that as 2.45 m.

## Conclusion

## How To Figure Square Feet For Your Home

Calculating the square footage of a home is relatively easy. To measure square feet, you just have to take it one room or space at a time. Measure the length, measure the width, multiply these two and you have the square footage of a space. For example, let’s say a bedroom in your home is 12 feet wide by 14 feet long. 12 X 14 = 168, so that bedroom has 168 square feet.

With one extra step you can easily measure square footage for odd sized rooms that do not end on a specific foot measurement. Let me show you how by slightly adjusting the example I used above.

Let’s say that bedroom is 12 feet 9 inches wide (or 153 inches) and 14 feet 9 inches long (or 177 inches). Notice what I did here. Ignore the foot measurement on your measuring tape all together. Instead, only look at the total inches for length and width. Here is the math with the extra step:

- Divide each inch total by 12 (153 divided by 12 is 12.75 and 177 divided by 12 is 14.75)
- Multiply the two numbers (12.75 x 14.75)
- Answer: 188, the room is 188 square feet

### What is included in square footage of a house?

The easiest way to calculate square footage is to measure all areas and rooms with a floor. If you can walk on it it counts. Square footage includes all of the spaces in your that is actual space. Your square footage total should include:

- Bedrooms and the closets
- Bathrooms
- Hallways
- Kitchens
- Living or recreation rooms
- Enclosed 3-season or all-season rooms
- Unfinished spaces like a basement

Garages, outdoor areas, and unfinished attics do not count as square footage.

### Finding the square footage of your home

To determine the square footage of you need some basic tools and to follow a few steps. The tools needed include:

- Pencil
- Paper
- Measuring tape

Follow these steps to accurately measure the square footage in your home:

- Measure every space except the garage, the crawl space, and the attic if it is not finished.
- Measure at the floor.
- Squaring off spaces is often the most practical way to capture all of the square feet.
- Multiply the length and the width of each space you measured.
- As you measure each space label each space as finished or unfinished and whether it is above grade or below grade

If you are shopping for a home to purchase, the square footage number you see in the listing or online is most likely the total finished square footage. However, it is important to know how much unfinished square feet is present and how much square footage is above grade or below grade. Each of these affect a home’s value.

### Finished Vs. Unfinished Square Footage

Many people are confused about are basements included in square footage. The answer is yes, basements are included in square footage. However, that square footage should be further classified as finished or unfinished.

Finished square footage is most often defined as a space where the walls, ceiling, and floor are all covered. What does that mean? For walls, it is covered when you cannot see the wall framing. The skeletal structure, electrical and pipes are covered with some other material such as drywall, panelling, or plaster. For a ceiling, this is the same as with walls, you cannot see the skeletal structure because it is covered with some other material.

As for the floor, if you are above the ground, the base material is usually subfloor also known as oriented strand board (OSB). It looks like plywood. If you are in the basement or the home is a ranch on a slab, the base material is likely concrete. To be finished square footage, you should not be standing directly on that material. Instead, there should be some type of floor covering over the concrete or OSB like carpet, hardwood flooring, or tile, or flooring laminate.

When measuring your home to determine its square footage make sure you put each amount of square footage for each room or space into the finished or unfinished column.

### Above Grade Square Footage vs. Below Grade Square Footage

Above grade square footage is square footage above the gradient line. The gradient line is where the earth meets the home. Square footage on the main floor and all floors above will almost always be above grade. This only gets a little tricky when the home is a bi-level, tri-level, quad-level, or hillside ranch.

These home models may have a basement, but the lowest level may be called the lower level. This happens because a level of the home is partly under the gradient line but also partly above it. Most areas consider a level like this to be the lower level and mark it as above grade square footage. Check with your local municipality, contractor, or a real estate agent for a certain answer to this question.

## Convert among square inch, square foot, square yard and square meter

You could, for example, perform all of your measurements in inches or centimeters, calculate area in square inches or square centimeters then convert your final answer to the unit you need such as square feet or square meters.

## Why Tenants, Homeowners, and Landlords Need to Know Square Footage

There are several reasons why tenants, homeowners, and landlords should all know how to calculate square feet:

- Knowing the square footage of a room can help you confirm if your furniture will fit.
- Knowing the square footage of a specific surface can help you estimate renovation costs. If you’re replacing a kitchen countertop, for example, you need to calculate the square footage of the countertop so you can get accurate quotes for the cost of the job.
- When you know how to calculate square feet, you can make sure you order the right amount of supplies and materials. If, for example, you plan to paint a wall that’s 12 feet long by 10 feet tall, you need to find the total square footage so you know how much paint to buy.
- Perhaps most importantly, knowing the square footage of homes and apartments helps you compare prices to find the best value. Let’s say you’re deciding between two similar apartments: Apartment A is $1,500 per month and Apartment B is $1,800 per month. Which is the better deal? Well, it depends on the square footage. If Apartment A is 500 square feet and Apartment B is 1,000 square feet, you’re getting more space for your money with Apartment B.

## How to calculate the square feet of a house

When preparing to measure the square footage of a home, be it a house, condo, or townhouse, start with a few simple supplies:

- Paper and pencil
- Calculator
- Measuring tape and/or laser measuring tool

If the property is a perfect rectangle, simply measure the length and width and multiply those two numbers together. For example, if your one-story house is 60 feet wide by 40 feet long, then your property is 2,400 square feet (60 x 40 = 2,400).

However, most properties have more complex floor plans. When this is the case, it’s helpful to follow these simple steps to measure square footage.

- Draw a rough sketch of your entire space, labeling all of the rooms you need to measure. Include hallways and vestibules as their own “room.”
- Measure the length and width, in feet, of each room. Then, multiply the length by the width to calculate that room’s square footage. For example: If a bedroom is 12 feet by 20 feet, it is 240 square feet (12 x 20 = 240). For each room, write the total square footage in the corresponding space on your sketch.
- Once each room is measured, add up all the measurements to determine your home’s total square footage.

Note: If you live in a tract home, condo or townhome community, you may be able to get architectural drawings or master builder plans of your floor plan. These may already have your square footage calculated.

## How many square feet is a 20×20 room?

The square footage of a room measuring 20 feet wide by 20 feet long is **400 square feet**. To calculate this you simply multiply the width by the height. 20ft × 20ft = 400 sq ft.

## How to find the square footage of a rectangle

- Measure the
**width**and**length**of the area in feet. - Multiply your length and width together to get your area.

Note: If your measurements aren't in feet, convert them to feet first using our length converter.

Once you've carried out your calculation, you will have your square feet (ft^{2}) figure. To calculate your cost of materials, simply multiply this figure by your price per square foot.

## Different Units of Measurement

Using square feet is the most common unit of measurement in American real estate. But it’s not your only option. For small projects, you might want to work in square inches. For big projects, like landscaping, square yards might make more sense. And in international real estate markets, square meters are the standard for home measurements.

Whatever your unit of measurement, the formula is the same. Multiply the length times the width to calculate the area of square and rectangular surfaces. Just make sure you’re using the same unit of measurement for your length and width. If you’re looking for square feet, measure both distances in feet; if you’re looking for square meters, measure both distances in meters.
