What size does a bedroom egress window have to be?
Every sleeping room shall have at least one (1) operable window or exterior door approved for emergency egress or rescue. The units must be operable from the inside to a full clear opening without the use of separate tools. Where a window is provided as a means of egress or rescue, they shall have a sill height of not more than 44” above the floor.

All egress or rescue windows from sleeping rooms must have a minimum net clear opening of 5.7 sq. ft. The minimum net clear opening height dimension shall be 24”. The minimum net clear opening width dimension shall be 20”.

To calculate the square footage of the opening, multiply the width of the opening in inches by the height of the opening in inches and dividing by 144. This measurement should be 5.7 minimum.
