Measure length and width of space

Once you have gathered the necessary tools, it's time to measure the length and width of the space you want to calculate the square footage for.

Begin by identifying the longest and widest straight lines within the space. These measurements will give you the length and width of the rectangular area. For irregular-shaped spaces, you may need to break it down into smaller rectangles or triangles to measure each section separately.

Position the measuring tape at the starting point of the length measurement. Ensure the tape is straight and flat against the surface you're measuring. Mark the end point of the length measurement with a pencil or tape marker.

Next, position the measuring tape at the starting point of the width measurement, perpendicular to the length measurement. Again, ensure the tape is straight and flat. Mark the end point of the width measurement.

Record both the length and width measurements in feet and inches on your notebook or clipboard. These measurements will be used to calculate the square footage in the next step.

Remember to carefully measure all sides of the space, including any alcoves, bay windows, or other architectural features that may affect the overall square footage.

Multiply length by width

Once you have measured the length and width of the space in feet and inches, you can calculate the square footage by multiplying these two measurements together.

To do this, follow these steps:

  1. Convert the length and width measurements to inches. There are 12 inches in a foot, so to convert feet to inches, multiply the feet measurement by 12. For example, if the length is 10 feet and the width is 8 feet, convert them to inches as follows:
    Length in inches = 10 feet * 12 inches/foot = 120 inches
    Width in inches = 8 feet * 12 inches/foot = 96 inches
  2. Multiply the length in inches by the width in inches. Using the example above:
    Square footage = 120 inches * 96 inches = 11,520 square inches
  3. Convert the square inches back to square feet by dividing the square inches by 144. There are 144 square inches in a square foot. So, dividing the square inches by 144 will give you the square footage:
    Square footage = 11,520 square inches / 144 square inches/square foot = 80 square feet

Therefore, the area of the space is 80 square feet.

Remember to always use the same units of measurement (either feet or inches) when multiplying the length and width. Mixing units can lead to incorrect results.

Convert to square feet if needed

In some cases, you may need to convert the square footage measurement to a different unit of area, such as square meters or square yards.

To convert square feet to square meters, multiply the square footage by 0.092903. For example, if you have a room that is 100 square feet, the area in square meters would be:

Area in square meters = 100 square feet * 0.092903 square meters/square foot = 9.29 square meters

To convert square feet to square yards, divide the square footage by 9. For example, if you have a room that is 100 square feet, the area in square yards would be:

Area in square yards = 100 square feet / 9 square feet/square yard = 11.11 square yards

Knowing how to convert between different units of area is useful for comparing measurements and ensuring consistency in your calculations.

Additionally, some countries use different units of measurement for area. For example, the United Kingdom commonly uses square meters, while the United States primarily uses square feet. When working with international clients or projects, it's important to be familiar with the appropriate unit of area to use.

Add areas for irregular-shaped rooms

Irregular-shaped rooms, such as those with bay windows, alcoves, or angled walls, require a slightly different approach to calculating square footage.

To measure the square footage of an irregular-shaped room:

  1. Divide the room into smaller, regular shapes, such as rectangles, triangles, or trapezoids. Each smaller shape should have straight sides and right angles.
  2. Measure the length and width of each smaller shape using the methods described earlier.
  3. Calculate the square footage of each smaller shape by multiplying its length by its width.
  4. Add the square footage of all the smaller shapes together to get the total square footage of the irregular-shaped room.

For example, consider a room with a bay window. You can divide the room into a rectangle and a triangle. Measure the length and width of the rectangle, and the base and height of the triangle. Calculate the square footage of each shape separately and then add them together to get the total square footage of the room.

It's important to be precise when measuring irregular-shaped rooms. Make sure to measure all sides and angles carefully to ensure accurate results.

Overall, laser measuring devices are a valuable tool for measuring square footage in larger spaces, as they offer speed, accuracy, and ease of use.

Draw a diagram for complex spaces

For complex spaces with multiple angles, curves, or irregular shapes, drawing a diagram can be helpful in calculating square footage accurately.

To draw a diagram:

  1. Start by measuring the overall length and width of the space. This will give you a rough estimate of the square footage.
  2. Divide the space into smaller, more manageable shapes. This could include rectangles, triangles, trapezoids, or even circles. Label each shape with its corresponding measurements.
  3. Draw the shapes on a piece of graph paper or use a computer-aided design (CAD) program to create a digital diagram.
  4. Calculate the square footage of each individual shape using the appropriate formulas. For example, to calculate the square footage of a rectangle, multiply the length by the width. To calculate the square footage of a triangle, multiply the base by the height and divide by 2.
  5. Add the square footage of all the individual shapes together to get the total square footage of the complex space.

Having a diagram can also be useful for visualizing the space and planning how to use it efficiently.
