Window Safety for Kids: Preventing Window Falls and Blind Cord Strangulation at Home

Quick answer: Window screens are made to keep bugs out, not children in. To prevent falls, the U.S. Consumer Product Safety Commission (CPSC) recommends window stops or window guards so windows open no more than 4 inches, and guards in rooms used for sleep should have an emergency release so the window can still be used as a fire escape. Keep cribs, beds and climbable furniture away from windows, open double-hung windows from the top sash, and replace corded blinds and shades with cordless products to prevent strangulation.

Windows are easy to overlook when childproofing. They sit above the floor, they look solid and the screen seems to block the opening. Yet a window fall can happen in seconds, often on a warm day when windows are open and a child climbs onto a bed or couch to look outside.

Window coverings bring a second hazard. Loops and cords on blinds and shades can wrap around a young child’s neck. Both risks are preventable with inexpensive hardware and a few placement changes. This guide is part of our family safety guide.

How Common Window Falls Are

A study by researchers at Nationwide Children’s Hospital, published in Pediatrics in 2015, estimated that an average of about 5,200 children a year were treated in U.S. emergency departments for injuries from falling out of windows between 1990 and 2008. Children under 5 were more likely to suffer head injuries and more likely to be hospitalized than older children.

Falls happen at every height. A first-story window can still be several feet above the ground, and the surface below, such as concrete or a patio, affects how serious the injury is. The study authors and the CPSC both point to the same prevention steps: limit how far windows open and keep children from climbing up to them.

Why Screens Are Not Enough

Screens are designed to keep insects out. They pop out of their frames with light pressure, and a child leaning or pushing against one can fall through with it. The CPSC and window industry groups both stress that a screen offers no fall protection. Treat an open window with a screen the same way you would treat an open window without one.

Window Stops and Window Guards

Two types of products limit openings:

Device	How it works	Best for
Window stop (opening control device)	Prevents a sliding or double-hung window from opening more than about 4 inches, with a release adults can use	Most windows, including bedrooms if it has an easy adult release
Window guard	A metal grill or bars installed in the window opening, with spacing small enough that a child cannot fit through	Upper floors, apartments, windows that must stay open

The CPSC recommends limiting window openings to 4 inches. Look for devices certified to ASTM F2090, the standard for window fall prevention devices, which requires an emergency release that an adult or older child can operate without tools. That release matters: windows in bedrooms are often required escape routes in a fire.

Install devices according to the manufacturer’s directions and test them. A stop that a toddler can push past does little good.

What Building Codes Require

For new construction and many renovations, the International Residential Code, which most U.S. states and cities adopt in some form, includes window fall protection rules. Under section R312.2, operable windows where the bottom of the opening is less than 24 inches above the finished floor and more than 72 inches above the ground outside must either limit the opening so a 4-inch sphere cannot pass through or have a window opening control device that meets ASTM F2090.

The same code requires emergency escape and rescue openings in sleeping rooms. That is why fall protection devices in bedrooms must allow quick release. Local codes vary, so ask your building department or landlord about what applies to your home.

Apartment Rules and Landlord Duties

Some cities go further. New York City’s Health Code has required window guards since 1976 in apartments where a child 10 years old or younger lives, and in common areas of those buildings. Landlords must install them, and tenants must notify the landlord if a child that age lives in the unit. Other cities have their own rules, so renters should ask their landlord or local housing agency.

If you rent and your city has no rule, ask your landlord whether you can install removable window stops, which often fit without drilling.

Furniture Placement

Most falls start with a climb. Children use beds, cribs, couches, toy chests and dressers as step stools to reach the window.

• Move cribs and beds away from windows. This also keeps cords out of reach. The AAP’s safe sleep guidance also recommends a clear, bare crib.
• Keep climbable furniture away from windows, including toy boxes, chairs and bookshelves.
• Anchor furniture to the wall, so a child who climbs it does not pull it over. See our guide to furniture and TV tip-over prevention.
• Check play areas. A playroom window above a window seat is an especially tempting spot.

Opening Windows Safely

Ventilation still matters, especially in summer. A few habits help:

1. Open double-hung windows from the top, lowering the upper sash instead of raising the lower one, so the opening sits out of a child’s reach.
2. Use window stops even when you are home and watching.
3. Close and lock windows that you are not using.
4. Supervise near open windows on balconies and upper floors.
5. Plant shrubs or soft landscaping below windows, which experts note can reduce injury severity compared with concrete, though it is no substitute for stops or guards.

Window Covering Cords

Corded blinds, shades and curtains with pull cords or inner cords can form loops that strangle young children. The CPSC has long warned about these hazards and urges families with young children to use cordless window coverings or coverings with inaccessible cords.

The voluntary industry standard ANSI/WCMA A100.1 requires most stock window coverings sold in stores to be cordless or have short or inaccessible cords. Custom products and older blinds may still have dangerous cords.

What to do:

• Replace old corded blinds with cordless versions in every room a child uses.
• If you cannot replace them yet, cut looped cords, install cord cleats high on the wall and wrap cords tightly, and keep furniture away from cords.
• Check inner cords on Roman shades and roll-up blinds, which can be pulled out to form a loop.
• Avoid tie-down devices that leave a long cord, since a child can still reach it.

Windows and Fire Safety

Window stops and guards should not trap your family in a fire. Make sure every adult and older child knows how to release the devices. Practice your home escape plan, including opening the window and removing any guard. Our home fire safety checklist covers escape plans, smoke alarms and drills.

For second-floor bedrooms, some families keep a fire escape ladder in the room. Practice using it from a ground-floor window so children know what it looks like, without climbing out from a height.

Teaching Kids About Windows by Age

Age	Teaching focus
Toddlers	“Windows are for looking, not climbing.” Supervision and devices do the work at this age.
Preschoolers	Do not lean on screens, push on windows or play near open windows.
School-age	Windows are an emergency exit only. Show how releases work, with an adult present.
Tweens and teens	Model safe habits; no sitting on sills, and no climbing out onto roofs.

Rules help, but devices and furniture placement matter most for young children, who climb before they understand danger.

Balconies, Decks and Stair Landings

Windows are not the only openings a child can fall from. Balconies, decks, lofts and stair landings with open railings pose similar risks.

• Check railing gaps. The IRC generally requires guards on open-sided walking surfaces more than 30 inches above the floor or grade below, with openings small enough that a 4-inch sphere cannot pass through. Older homes may not meet that rule.
• Add a barrier such as plexiglass panels or railing netting if gaps are wider, especially on balconies and lofts.
• Keep furniture off balconies or away from the railing. Chairs, planters, coolers and toy bins all make easy steps.
• Lock balcony doors with a high latch a child cannot reach, and supervise whenever a child is outside on an upper floor.
• Use gates at the top of stairs and at loft openings. A hardware-mounted gate is the right choice at the top of stairs.

When Visiting or Traveling

Hotels, vacation rentals and relatives’ homes may have windows that open wide, low sills and corded blinds. When you arrive, walk through the rooms where your child will sleep and play. Close and lock windows, move beds and chairs away from them and tie up any cords out of reach. Portable window stops that fit without tools are easy to pack. In a high-rise hotel, ask the front desk whether the windows lock or have limiters.

Seasonal Checks

Window falls rise in spring and summer, when windows are open more often. The Window Safety Task Force, convened with the National Safety Council, promotes Window Safety Week each spring as a reminder. A good routine is to check stops, guards and cords when you change smoke alarm batteries or swap seasonal clothing. Our summer safety guide has more warm-weather tips.

If a Child Falls From a Window

Call 911 right away for any fall from a window, balcony or deck, even if the child seems fine at first. Head and internal injuries are not always obvious. Unless the child is in immediate danger where they landed, do not move them, since moving a child with a neck or back injury can make it worse. Stay with the child, keep them still and calm and follow the dispatcher’s instructions until help arrives.

After any fall or near miss, go back through the room and ask what made the window reachable and openable. A new piece of furniture, a missing stop or a window left open is usually the answer, and fixing it protects younger siblings too.

A Quick Window Safety Checklist

• Window stops or guards on windows children can reach, limiting openings to 4 inches
• Emergency release on any device in a bedroom
• Cribs, beds and climbable furniture moved away from windows
• Cordless window coverings in every room children use
• Windows closed and locked when not in use
• Everyone in the home knows how to release devices in a fire

Frequently Asked Questions

Do window screens keep children from falling?

No. Screens are built to keep insects out and can pop out under a child’s weight. Use window stops or guards instead.

How far should a window open with a child in the house?

The CPSC recommends no more than 4 inches.

Are window guards a fire hazard?

They can be if they cannot be opened quickly. Choose devices with an emergency release, such as those certified to ASTM F2090, especially in bedrooms.

Are cordless blinds required?

Many stock window coverings sold in stores are cordless or have short or inaccessible cords under the industry standard, but older and some custom products may still have cords. Replace corded products in homes with young children.

Who installs window guards in an apartment?

It depends on local law. In New York City, landlords must install them where a child 10 or younger lives. Ask your landlord or local housing agency about the rules where you live.

The Bottom Line

Window safety comes down to three steps: limit openings to 4 inches with stops or guards that adults can release, keep climbable furniture away from windows and go cordless on window coverings. Add a quick seasonal check, and your windows stop being one of the overlooked hazards in your home.
