How do I know what size egress window well to get?

2 months ago

Hi everyone! I am adding an egress window to a new basement. The window itself is 48" x 48" but how do I know what size well should go with this? A standard width seems to be 50", but is that wide enough or do I need more than an inch of clearance on each side? Also, height-wise, does the bottom of the well align exactly with the bottom of the window typically?

Also if anyone has any feedback of benefits of fiberglass vs metal wells, I welcome it! Thank you!
