To accurately measure the length of a room, follow these steps:

  1. Select the right measuring tool: Choose a measuring tape or laser measure that is long enough to span the length of the room. For larger rooms, consider using a measuring wheel.
  2. Determine the starting point: Identify a fixed point on one wall of the room to serve as your starting point. This could be a corner, a doorway, or any other easily identifiable feature.
  3. Extend the measuring tool: Position the measuring tool at the starting point, ensuring that it is flat against the wall and fully extended.
  4. Take the measurement: Slowly extend the measuring tool to the opposite wall, keeping it parallel to the floor. Mark the measurement at the point where the tool meets the wall.
  5. Record the measurement: Write down the measurement in feet and inches. If using a laser measure, the measurement will be displayed digitally.

Once you have measured the length of the room, you can proceed to measure the width. By multiplying the length and width, you will determine the square footage of the room.

Measure room width

To accurately measure the width of a room, follow these steps:

  • Select a perpendicular wall: Choose a wall that is perpendicular to the wall where you measured the length. This ensures that you are measuring the width of the room at its widest point.
  • Determine the starting point: Identify a fixed point on the perpendicular wall to serve as your starting point. This could be a corner, a doorway, or any other easily identifiable feature.
  • Extend the measuring tool: Position the measuring tool at the starting point, ensuring that it is flat against the wall and fully extended.
  • Take the measurement: Slowly extend the measuring tool to the opposite wall, keeping it parallel to the floor. Mark the measurement at the point where the tool meets the wall.

Once you have measured the width of the room, you can proceed to multiply the length and width to determine the square footage of the room. Remember to convert any measurements in inches to feet before multiplying.

Convert to feet

Before multiplying the length and width of a room to calculate the square footage, it is important to ensure that both measurements are in the same unit. In most cases, it is easiest to convert both measurements to feet.

To convert inches to feet, divide the measurement in inches by 12. For example, if you measured the length of a room to be 156 inches, you would divide 156 by 12 to get 13 feet.

If you are using a measuring tool that displays measurements in feet and inches, such as a tape measure, you can simply read the measurement directly. However, be sure to pay attention to the units and ensure that you are using the correct measurement for your calculations.

Once you have converted both the length and width measurements to feet, you can proceed to multiply them together to determine the square footage of the room.

Remember, consistency in units is crucial for accurate calculations. Always use the same unit of measurement throughout the entire process to avoid errors.

Multiply length by width

To calculate the square footage of a room, you need to multiply the length and width measurements together. This can be done using a calculator or simply by multiplying the numbers in your head.

  • Ensure consistent units: Before multiplying the length and width, make sure that both measurements are in the same unit. Typically, it is easiest to convert both measurements to feet.
  • Multiply the measurements: Once you have converted the measurements to feet, simply multiply the length by the width. For example, if the length of the room is 13 feet and the width is 10 feet, you would multiply 13 by 10 to get 130 square feet.
  • Interpret the result: The result of multiplying the length and width is the square footage of the room. This value represents the total area of the room’s floor space.

Once you have calculated the square footage of the room, you can use this information for various purposes, such as planning renovations, installing flooring, or determining the appropriate size of furniture.

Include closets

When calculating the square footage of a room, it is important to include the area of any closets that are located within the room. Closets are considered to be part of the livable space of a room, even though they are not directly accessible from the main area of the room.

To include the area of a closet in your calculations, simply measure the length and width of the closet in feet and multiply these measurements together. Then, add the square footage of the closet to the square footage of the main area of the room.

For example, if the main area of a room measures 13 feet by 10 feet, and there is a closet that measures 3 feet by 5 feet, the total square footage of the room would be 130 square feet (13 feet x 10 feet) + 15 square feet (3 feet x 5 feet) = 145 square feet.

Including the area of closets in your calculations ensures that you have an accurate measurement of the total livable space in the room.

However, it is important to note that some types of closets, such as walk-in closets, may be excluded from the square footage calculations. Be sure to check with local building codes or real estate guidelines to determine which types of closets should be included.

Exclude non-livable space

When calculating the square footage of a room, it is important to exclude any areas that are not considered to be livable space. This includes areas such as hallways, bathrooms, and staircases.

  • Identify non-livable areas: Walk around the room and identify any areas that are not intended for living purposes. Common examples include hallways, bathrooms, staircases, and closets that are not directly accessible from the main area of the room.
  • Measure the non-livable areas: Once you have identified the non-livable areas, measure the length and width of each area in feet. Multiply these measurements together to determine the square footage of each non-livable area.
  • Subtract the non-livable area: Subtract the square footage of each non-livable area from the total square footage of the room. This will give you the square footage of the livable space in the room.

Excluding non-livable space from your calculations ensures that you have an accurate measurement of the usable space in the room. This information is important for a variety of purposes, such as determining the appropriate size of furniture, planning renovations, or calculating the cost of flooring materials.

Round to nearest square foot

When calculating the square footage of a room, it is common to end up with a measurement that includes a fraction of a square foot. For most purposes, it is not necessary to be this precise. Therefore, it is customary to round the square footage to the nearest whole number.

  • Determine the decimal value: If the square footage measurement includes a decimal value, determine the value of the decimal place. For example, if the measurement is 123.45 square feet, the decimal value is 0.45.
  • Round up or down: If the decimal value is 0.5 or greater, round the measurement up to the next whole number. If the decimal value is less than 0.5, round the measurement down to the nearest whole number. In the example above, since the decimal value is 0.45, which is less than 0.5, we would round the measurement down to 123 square feet.

Rounding the square footage to the nearest whole number makes it easier to work with the measurement and to communicate it to others. It also provides a more accurate representation of the actual usable space in the room.

Verify your calculations

Once you have calculated the square footage of a room, it is important to verify your calculations to ensure that they are accurate. There are a few different ways to do this:

Recalculate the square footage: Using a calculator or a piece of paper, recalculate the square footage of the room from the beginning. Be sure to follow the same steps and use the same measurements that you used the first time.

Check for common errors: Look for common errors that could have occurred during your calculations. For example, make sure that you converted all measurements to feet before multiplying them together. Also, check to see if you accidentally added or subtracted the square footage of any non-livable areas.

Compare your results to similar rooms: If you have access to information about similar rooms, compare your square footage calculations to those measurements. This can help you to identify any significant discrepancies in your calculations.

Use a room measurement calculator: There are a number of online room measurement calculators available that can help you to verify your calculations. Simply enter the length and width of the room, and the calculator will calculate the square footage for you.

By verifying your calculations, you can ensure that you have an accurate measurement of the square footage of the room. This information is essential for a variety of purposes, such as planning renovations, installing flooring, or determining the appropriate size of furniture.
