Are you putting enough thought into how big or wide your new windows will be for your next project? According to our team of window replacement experts, picking the right size is the secret to getting a lot of value out of your new windows so here are a few pointers from our team of experts to help you get started.
While there are no restrictions on how close your window frame’s top edge is to the ceiling, keep in mind that you still need to leave some space above your windows. Otherwise, you’ll have trouble working in window treatments like blinds or curtains later on. On the other hand, setting it too low can limit the amount of light your window can get during the daytime.
If you’re getting operable windows like double-hung windows, you need to be aware of the minimum elevation. All operable windows must have sills no lower than 24 inches (2 feet) from the floor. This means you can leave out larger window options that would force you to go below that threshold.
A typical window height from floor level ranges from about 24 to 36 inches. However, the proper placement is shaped by the opening, room function, privacy needs, views and local building codes.
To leave room for furniture, bedroom windows frequently have sills up to 36 inches. When local building codes call for at least one window to serve as an emergency escape and rescue opening, the clear opening and window sill height must satisfy all outlined requirements. Basement egress windows also need a window well with at least 36 by 36 inches of clear horizontal space, but be sure to confirm each requirement on a local basis.
Living room window sills can sit 18 to 24 inches high when wide views and natural light are desired. However, a height of 36 to 48 inches from the floor preserves wall space, which also benefits seating. Aligning the window tops with door headers can create a cleaner line through the room.
Kitchen sills typically sit 36 to 42 inches above the floor to clear countertops, backsplashes and faucets. Bathroom sills, meanwhile, usually range from 48 to 60 inches. Patterned or obscure glass is good for adding privacy and admitting daylight simultaneously.
First, measure from the finished floor to the bottom of the interior window sill. After that, measure from the floor to the bottom of the header. To estimate window height, subtract the planned sill height from the floor-to-header measurement. Record the visible opening’s width and height, make sure the sill and floor are level and account for all nearby counters, faucets, furniture or window treatments. While these exterior measurements can reveal differences in wall depth, they shouldn’t replace professional measurements.
Egress and fall protection rules are in place to address different risks. Model-code fall-protection provisions apply when an operable window is over 72 inches above exterior grade and its clear opening starts less than 24 inches above the interior floor. Under certain conditions, safety glazing can also be required for glass that’s close to the floor. Since codes and amendments often vary, consult your local building department before changing an opening.
Because the windows’ size has an effect on lighting and heat exposure, you have to consider where your new windows will be installed. South-facing windows have to be big enough to provide you plenty of light and warmth during winter, while north-facing windows have to be smaller to keep your home cool during summers.
Thinking of adding big gliding windows to a living room? You may have to check your home’s current insulation before going ahead. Homes with thick walls and good insulation can afford to have bigger windows because they do a better job of keeping indoor temperatures consistent. Otherwise, you’ll have to go for smaller windows that have a lesser effect on your home’s temps, especially during extremely hot or cold days.
