## 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.

## DETERMINE YOUR WALL LAYOUT

Here is a sample wall profile. If your wall height varies, divide the wall panels into segments according to height. This will assist in effectively calculating the square footage, as well as eliminate excess materials. (See the Front View, Side View, and Overhead view drawings below).

## 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.

## 4. What is Net Cleanable Square Feet?

**Net Cleanable Square Feet (“NCSF”)** is the sum of all floor area that requires custodial services. NCSF is a great metric to know, especially for your facility’s custodial personnel. Having accurate NCSF measurements can help determine custodial staffing, inform budgeting and aid in service provider solicitation.

Custodial budgets will realistically contain chemicals, paper supplies, equipment and custodial labor costs to get the job done. Not knowing your facility’s true NCSF might mean that you are budgeting too little or too much for cleaning.

### How to Calculate Net Cleanable Square Feet

Determine the square footage of each room that needs to be cleaned. Areas that require no cleaning, such as closet areas and mechanical rooms, should not be included. Once you’ve gathered square footage (minus non-cleanable areas) for all rooms, add them together. This number is your total square footage that needs to be cleaned.

You can take this process a step further and add cleaning costs to the equation. Multiply total cleanable square footage by a base price for cleaning. For instance, if your total area to be cleaned is 5,000 square feet and the price per square foot is 25 cents, you can multiply $0.25 times 5,000 to get a total of $1,250 for cleaning fees.

## 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.

## How much to allow for waste?

To allow for waste, you must consider the installation. For most standard installations, 10% extra for waste is sufficient. Percentage of waste for more elaborate patterns like running tile on a 45 degree angle, herringbone or cross hatch, consult with your installer. Add 15% for tile being installed in a room with lots of jogs and corners. These installations will require more cuts and thus more waste.

Length x Width + Waste = Amount Needed

## Window and Door Concerns

Since all rooms have at least one door and most have windows, feel free to subtract the square footage of these elements from your wall calculations. Either measure the square footage of each window and door individually, or estimate these numbers. The typical door is 21 square feet, while the average window is 15 square feet. Subtract the total square footage of windows and doors from the wall square footage to determine the total square footage of *wall space requiring paint*.

The typical online paint calculator square feet measurements include estimates, not exact measurements, of window and door sizes, as well.

## How many square feet is a 12×12 room?

The square footage of a room measuring 12 feet wide by 12 feet long is **144 square feet**. To calculate this you simply multiply the width by the height. 12ft × 12ft = 144 sq ft.

## How to Find the Square Footage of a Room with Four Corners

If your room has straight walls and four corners, the way to figure square footage is simple. You can use a tape measure to measure the length and width of the room in feet. Then, you can multiply those two numbers together. The resulting number is the square footage of your room.

## Measuring for Schluter Profile Edging

Measure the length of any outside edge where your tile edge would be exposed. Not all edging is the same. Speak to your design associate about different uses.
