That said, there is a standard bathroom window size of which two are very common: Width 36-84 inches; Height 24-60 inches. A window size notation, by the way, is the width and height combined for size windows.

But once again, the manufacturers have the discretion to decide what they deem standard. You can also expect these “standards” to change after some time.

Awning windows are usually used together with other styles and are easy to close and open. You can even keep these weatherproof windows open during light rain. The inside of the window should have proper insulation to avoid condensation.

The standard width for awning windows can range from 2″ to 3’10”. Meanwhile, the standard window height for these windows is at 1’8″ up to 7’8″. The simple size notation on the lower end for the replacement window is 2018.

Casement Windows

Casement windows are ideal replacement windows for narrow and tall spaces. Also called crank windows, the window openings can either be outward or inward like a door. These windows often have a tiny crack at the base, to allow turning for the window to open outward.
