Egress Window Requirements for Home (What to Know)

The Complete Guide to Bedroom Egress Window Sizes and Requirements

When it comes to designing your dream bedroom, windows are often the unsung heroes. They let in gorgeous natural light, create a connection to the outdoors, and enhance your space’s overall vibe. But your bedroom window might also be a lifesaver in case of an emergency. And because of that, knowing the right bedroom egress window size is more important than any pretty design feature in your room.

Windows aren’t just about natural light and beautiful views—they also play a major role in home safety. If you’re designing a new home, remodeling an older home, or adding a new sleeping room, you’ll need to make sure your windows meet egress requirements for safety and building code compliance.

Why? Because in the case of a fire or event of an emergency, a properly sized egress window serves as a safe means of escape for anyone inside of the room. It also gives rescue personnel easy access, ensuring your family’s safety. What’s more important than that?

But don’t worry—just because these windows are required by the egress window code doesn’t mean they have to look boring! An egress window will let in beautiful natural light while ensuring your bedroom meets section R of the International Residential Code (IRC). A light-filled space and safety!

What Is an Egress Window?

Simply put, an egress window is a required emergency escape window that provides a means of egress from a habitable space. These include bedrooms, media rooms, or family rooms.

Egress windows must meet specific size requirements to allow someone to exit safely in the event of a fire or other emergency situation. It also needs to be fully operable—meaning no use of keys, tools, or special knowledge should be required to open it.

Why Are Bedroom Egress Windows Important?

• Egress Windows are Life Saving – In a case of an emergency, they provide a safe exit and allow rescue personnel to enter.
• They’re Legally required – The national building code mandates them for every new egress window in a sleeping room or habitable attic.
• Adds value – Compliant escape rescue openings increase resale value and make your home safer.

Bedroom Egress Window Size Requirements

Now, let’s talk numbers. Every bedroom must have at least one operable emergency escape window that meets egress laws and egress codes for an emergency situation.

Here Are the Key Size Requirements:

• Minimum net opening area: 5.7 square feet (5 sq. ft. for basements).
• Minimum width: 20 inches.
• Minimum height: 24 inches.
• Maximum sill height: 44 inches from the finished floor.
• Fully open position must allow for the normal operation of the escape.

In older homes, when installing a replacement window in an existing frame, be sure to check that the required dimensions of the window meet the latest building code requirements (including the Florida building code, if applicable).

Choosing the Right Bedroom Egress Window Size & Style

Not all windows qualify as egress windows. They need to meet the minimum size opening area, be fully operable, and provide a safe emergency exit. Here are some of the best options:

Casement Windows (Great for Small Spaces!)

• Best net opening size
• Hinged at the side (side-hinged door style)
• Swings open completely, maximizing clear height opening

Double-Hung Windows

• Classic and versatile
• Can meet required emergency escape size—but only if the lower sash opens wide enough for the clear opening size required

Sliding Windows

• Sleek, modern option
• Needs sufficient inside width and minimum horizontal area of the window

Basement Egress Windows

• Must include a window well
• If deeper than 44 inches, a permanently affixed ladder is required

• The normal operation of the escape must not require excessive force or special knowledge.

Bedroom Egress Windows in Attics & Lofts

Final Thoughts: Safety & Style Go Hand in Hand

A properly sized egress window isn’t just a nice-to-have feature for your home—it’s an essential safety requirement that provides a secure means of escape in case of an emergency. Beyond offering peace of mind, egress windows are required by building codes to ensure occupants can exit quickly and safely if needed. Whether you’re building a brand-new home, giving an older house a much-needed update, or transforming a basement into a cozy bedroom, following the proper egress window code isn’t just about compliance—it’s about creating a safe and functional living space. The right window can also bring in valuable natural light, improving both the aesthetics and livability of a room, particularly in lower-level spaces where daylight can be limited.
