The formula is:

$\text{OAP} = \frac{\text{OA}}{\text{TA}} \times 100$

Variables

Variable	Meaning
OAP	Open Area Percentage (the percentage of open area)
OA	Open Area (the area that is open or unoccupied)
TA	Total Area (the total area of the object or surface)

How to Calculate?

First of all you are required determine the open area (OA) of the object or surface. Now, determine the total area (TA) of the object or surface. After that, divide the open area (OA) by the total area (TA). Finally, multiply the result by 100 to calculate the Open Area Percentage (OAP).

Solved Exercises:

Example 1:

Given:

Open Area (OA) = 50 square meters
Total Area (TA) = 200 square meters

Calculation	Instructions
Step 1: OAP = $\frac{OA}{TA} \times 100$	Start with the formula.
Step 2: OAP = $\frac{50}{200} \times 100$	Replace OA with 50 square meters and TA with 200 square meters.
Step 3: OAP = $0.25 \times 100$	Divide 50 by 200 to get 0.25.
Step 4: OAP = 25%	Multiply 0.25 by 100 to get the Open Area Percentage.

Answer:
The Open Area Percentage is 25%.

Example 2:

Given:

Open Area (OA) = 75 square meters
Total Area (TA) = 300 square meters

Calculation	Instructions
Step 1: OAP = $\frac{OA}{TA} \times 100$	Start with the formula.
Step 2: OAP = $\frac{75}{300} \times 100$	Replace OA with 75 square meters and TA with 300 square meters.
Step 3: OAP = $0.25 \times 100$	Divide 75 by 300 to get 0.25.
Step 4: OAP = 25%	Multiply 0.25 by 100 to get the Open Area Percentage.

What is the Open Area Percentage Calculator?

The Open Area Percentage Calculator is very helpful when it comes to know the percentage of an open or unoccupied object’s or surface’s area. This metric is particularly useful in various engineering, architectural, and design applications, where it is important to understand the proportion of open space relative to the total area.

The formula $\text{OAP} = \frac{\text{OA}}{\text{TA}} \times 100$ calculates the Open Area Percentage by dividing the open area (OA) by the total area (TA) and multiplying by 100. It helps in assessing ventilation, light penetration, structural integrity, and other factors where open space plays a critical role.

Final Words:

The Open Area Percentage Calculator is a helpful tool for creating balanced, sustainable, and nice-looking spaces. Whether in city planning, real estate development, environmental conservation, or recreational planning, knowing the percentage of open space in an area is crucial for making places that enhance the quality of life for individuals and communities.
