Egress Calculator

This Egress Calculator is intended to provide you with the specifications needed to determine if a custom sized egress window meets egress requirements. Due to the varying nature of windows, this calculator will only be accurate for egress windows from the Great Egress Company.

To Use:

  • Select the type of window from the drop down.

  • If the window is wider than it is tall, we recommend the reverse hopper.

  • If it is taller than it is wide, we recommend the side hinge.

  • If you're a sucker for European style, check out the tilt-and-turn

  • Enter the Width and Height (in Inches) of the window you are considering purchasing. 

  • Press Calculate.

  • The table below will populate with the specs that you need to determine if this window will meet egress requirements in your area
