Standard Window Sizes For Every Home

Standard window sizes aren’t discovered by shopping for windows at your local hardware store. There are standard window sizes for every home. Each size will depend on your home and what you want. 

Standard Window Sizes

Window dimensions are unique to the room where they’re installed. A kitchen window does not have the same dimensions as a window in a living room. If you know the type of window you want, it’s as helpful as knowing its size. 

History of the Window

Asian countries used paper windows as early as 100 BC. The Romans had glass windows 2,000 years ago. And in 17th century England, glass replaced animal horns for the modern-day window. Glass windows were a privilege enjoyed by the wealthy.

In the US, beginning in the 19th century, Grecian-style windows were the norm throughout most of the century. Starting in the 20th century, standard window frames were manufactured and available across the country. The balloon-framed windows were built with hinged openings. The single-pane windows weren’t heavy, which made installation easy.

In the 50s, windows were bare-edged, metallic, and rectangular. The windows had wood frames and homes were built with shutters for protection. By the end of the decade, double-paned window styles were introduced to the public.

In the 70s, double-pane windows became the norm. Single-pane windows were phased out.

Differences Between Single Pane And Double Pane Windows

Single pane windows may not be common today, but you will find them in older homes. Almost all windows in a residential home will be double-pane windows. 

Single-Pane Windows

Single-pane windows were common in residential homes up until the 70s. Today, they aren’t used. Older homes have single-pane windows.

The problem with single-pane windows is how they don’t insulate homes as well as their double-pane counterpart. When you’re trying to heat or cool your home, single-pane windows are effective in protecting your home from outdoor climates. 

If single-pane windows have a benefit, it’s that they’re cheap. But the money you save on buying cheap windows, you spend later when trying to heat or cool your home. 

Double Pane Windows

Double-pane windows are the norm in homes across the country. In California, for example, it is against the law for contractors to install single-pane windows. If a homeowner in Los Angeles wants single-pane windows, then they will have to install the windows themselves. 

Although double pane windows cost more, the money you save on your energy bills will be worth it in the long run. Window technology now includes non-toxic, non-visible argon gas in the space between panes. 

Double-pane windows protect you from extreme weather conditions and outside noise pollution. The glass is also harder to break. You can also have the windows customized to include a laminated security glass.

How To Find What Size Of Window You Need

How To Find What Size Of Window You NeedView in gallery

The most important window size is the window size that you need. When measuring for a window replacement, try measuring your opening instead of your window. Measuring a window can be difficult.

There are moisture barriers, lips, and all sorts of protrusions that can confuse you. So just measure the window opening and write down the measurements. Measure the jamb from side to side and end to end. 

This is the measurement you’ll give the manufacturer or associate at the hardware store. If you want to pick one out yourself, then you will need to deduct 1/2 in from the measurement for the window to fit.

This is something that associates and contractors do automatically but is something you’ll do manually. It’s better for the window to be slightly too small than too big. Because you can always fill in the gap.

A great option for filling gaps is caulk or silicone. Here we have a great guide on the difference between caulk and silicone where you can learn the basics on how to use each of them. 

Burglar-Proof Windows

The type of window and size of the window that you get matter. In more than 70% of home break-ins, burglars break through the window or door by breaking the glass.

While an alarm system offers the best protection, locks won’t be as effective if your windows are easy to break.

Here are the three most popular options to protect your home:

  1. Glazing – is a simple clear coat that can add protection and security to your window. Double-glazed windows are very hard to break into and are one of the cheapest anti-burglary options that really work. 
  2. Film– A security window film is another great option. You can add it to your window and it won’t be visible to the naked eye. But it offers great protection that doesn’t allow burglars to gain entry after breaking the glass. 
  3. Glass – Getting riot glass, or even something less secure is your safest option. This way, they can’t break the glass. However, unbreakable glass is expensive, so it may not be your easiest decision to make. If you’re looking for security systems, make sure you get a good one. Security systems aren’t cheap, but it is best to get your info from third parties.
