Once you have the length, measure the width of your space at its widest point. Again, measure in a straight line and record the measurement in the same unit as the length.
- Consider Obstructions:
If there are any permanent fixtures or obstructions within your space, such as pillars, fireplaces, or built-in furniture, make note of their dimensions and position. These obstructions will need to be excluded from your square footage calculation.
- Accuracy is Key:
Ensure that your measurements are as accurate as possible. Small errors can lead to significant discrepancies in your final square footage calculation.
Once you have accurately measured the length and width of your space, you're ready to move on to the next step: multiplying the two measurements to calculate the square footage.
Multiply Length by Width
Now that you have the length and width measurements of your space, it's time to multiply them to calculate the square footage.
- Simple Multiplication:
To calculate the square footage, simply multiply the length measurement by the width measurement. The result will be the square footage of your space.
- Units of Measurement:
Make sure that you use the same unit of measurement for both the length and width. If you measured in feet, multiply the length in feet by the width in feet. If you measured in meters, multiply the length in meters by the width in meters.
- Decimal Points:
If your measurements include decimal points, be sure to include them in your calculation. For example, if the length is 12.5 feet and the width is 8.3 feet, the square footage would be 12.5 x 8.3 = 104.375 square feet.
- Rounding:
Once you have the result of your multiplication, you can round it to the nearest whole number. However, if you plan to use the square footage for detailed planning or construction purposes, it's best to keep the exact measurement with decimal points.
By multiplying the length and width measurements, you have now determined the square footage of your space. This measurement provides you with a valuable starting point for various space-related calculations and planning.
Convert to Square Feet
In many parts of the world, the standard unit of measurement for square footage is square feet (sq ft or ft²). If you have your measurements in other units, such as inches, yards, or meters, you'll need to convert them to square feet to ensure consistency and ease of understanding.
Here's how to convert different units to square feet:
- Inches to Square Feet:
To convert inches to square feet, divide the square inches by 144. For example, if you have a measurement of 288 square inches, divide it by 144: 288 ÷ 144 = 2 square feet.
To convert yards to square feet, multiply the square yards by 9. For example, if you have a measurement of 3 square yards, multiply it by 9: 3 × 9 = 27 square feet.
To convert square meters to square feet, multiply the square meters by 10.7639. For example, if you have a measurement of 25 square meters, multiply it by 10.7639: 25 × 10.7639 = 269.1 square feet.
To convert acres to square feet, multiply the acres by 43,560. For example, if you have a measurement of 0.5 acres, multiply it by 43,560: 0.5 × 43,560 = 21,780 square feet.
By converting your measurements to square feet, you can easily compare and combine different areas, ensuring accurate and consistent square footage calculations.
Include All Areas
When calculating the square footage of your space, it's important to include all areas, even those that may seem insignificant. This ensures that you have an accurate representation of the total usable space.
- Main Areas:
Start by measuring the main areas of your space, such as bedrooms, living rooms, kitchens, and bathrooms. Be sure to include all the floor space within these areas, from wall to wall.
Don't forget to include the square footage of closets, pantries, and other storage spaces. These areas may not be directly habitable, but they contribute to the overall functionality and value of your space.
Hallways, corridors, and staircases are often overlooked, but they should be included in your square footage calculation. These areas provide circulation and access to different parts of your space.
If your space includes balconies, patios, or decks, be sure to include their square footage as well. These areas extend the usable space of your property and can be valuable for outdoor living.
Even if certain areas of your space are unfinished or not currently being used, they should still be included in your square footage calculation. These areas have the potential to be developed and utilized in the future.
By including all areas in your square footage calculation, you'll have a more accurate understanding of the total size and value of your space.
Exclude Obstructions
When calculating the square footage of your space, there are certain areas that should be excluded to ensure an accurate measurement of the usable space.
- Permanent Fixtures:
Permanent fixtures such as fireplaces, built-in cabinets, and structural columns should be excluded from your square footage calculation. These elements are not considered usable space and can obstruct the flow of movement within a room.
Interior walls, including partition walls and half walls, should also be excluded from your calculation. These walls divide the space into different rooms and are not considered part of the usable floor area.
While staircases provide vertical circulation, they are not typically included in square footage calculations. However, the area underneath a staircase can be included if it's used as a storage or functional space.
Any areas that are not accessible or usable, such as crawl spaces, mechanical rooms, and unfinished attics, should be excluded from your square footage calculation. These areas do not contribute to the habitable space of your property.
By excluding obstructions and unusable areas from your square footage calculation, you'll have a more accurate representation of the functional and livable space available in your property.
Consider Irregular Shapes
Many spaces, especially those with unique architectural features or unusual layouts, may have irregular shapes. Calculating the square footage of these spaces requires a slightly different approach.
