Depends on local codes but I never go less then 7 ft
The minimum required egress window height from the floor for a safe and compliant installation is typically 24 inches.
To calculate the size of an egress window, you need to follow these steps: Determine the minimum required size for an egress window in your area. This is typically based on building codes and regulations. Measure the width and height of the window opening in inches. Multiply the width by the height to calculate the total square inches of the window opening. Ensure that the total square inches of the window opening meets or exceeds the minimum required size for an egress window in your area. By following these steps, you can accurately calculate the size of an egress window.
The average height of a window is 3'-7" and the width is 3'.
Depends on the window
Windows differ in height and style by make and model, but the average car window height is19.5-inches. Standard window heights on vans and SUV's have a standard height of 21.9-inches.
Measure the height and width of the window in inches. Next, multiply the height of the window by the width of the window. Then divide that number by 144 to get square feet.
Emergency egress requirments. 5.0 sqr ft at grade level and 5.7 sqr ft below or above grade (second floor and above). 24" clear opening height minimum. 20" clear opening width minimum.
You do need to have ventilation in a bedroom. But more important you need egress. At least one window in each bedroom must be of sufficient size to permit the occupants to escape a fire and also to allow a fully outfitted firefighter to enter. An egress window must satisfy all four International Residential Code (IRC) criteria: Minimum width of opening: 20 in. Minimum height of opening: 24 in. Minimum net clear opening: 5.7 sq. ft. (5.0 sq. ft. for ground floor). Maximum sill height above floor: 44 in. ;) MINI

To install an egress window in a bedroom for safety and compliance, the window must meet specific size requirements, typically at least 5.7 square feet in area and have a minimum opening height and width. It should also be easily accessible and operable without the use of keys or tools. Additionally, the window should be located at a height that allows for safe exit in case of emergency. Compliance with local building codes and regulations is essential when installing an egress window.
1/10 th of floor height
For a smaller window such as a 36" X 36", the average height above the floor is about 32" to 36". For a taller window, it may be as little as 20-22" above the floor.
