Final answer:
The minimum height and width for an egress window is 15 inches according to newer recommendations, but an older 'rule of thumb' suggests a height of 7-8 times the diameter and a width of 5 times the diameter.
Step-by-step explanation:
Egress Window Dimensions
The dimensions for an egress window are determined by safety standards and building codes. According to newer recommendations, the minimum height for an egress window should be 15 inches and the minimum width should be 15 inches.
However, an older 'rule of thumb' suggested a height of 7-8 times the diameter and a width of 5 times the diameter. For instance, if the diameter is 3 inches, the older recommendations would suggest a minimum height of 21-24 inches and a minimum width of 15 inches.
In general, it is important to check local building codes and regulations to ensure compliance with egress window dimensions.
