Casement Window Standard Sizes 101

Casement window in standard sizes is very popular because their design has many innate benefits—including light, safety, and weather resistance.

They come in a variety of sizes that can be adapted to just about any requirement in any style of home. Some homeowners choose to customize their windows, but there are also some standard-sized casement windows for you to consider.

What About Casement Window Standard Sizes?

Casement window sizes vary from very small to very big. You probably have a good idea of the size you want, but you need to consider several factors before settling on a specific size.

You first need to decide whether you want a vent window or a fixed one that doesn’t open. If you want the former, you need to decide how you want them to open. Your options include windows that swing out to either the right or left and push casement windows.

What particular configuration do you want? For example, do you want a vent casement window on the side of a picture window? Do you want them to flank a picture window in a bay window? Do you want small vent windows in your kitchen but large ones in your living room? What about a transom window above the casement windows in the bedrooms?

You can go ahead and determine the window dimensions that suit your requirements with these factors in mind.

Measuring Casement Windows for Replacement

It’s best to measure replacement windows on the inside of the house and not on the outside. Dimensions are presented in a set of four numbers. The first two numbers represent the width and the second two represent the height or length.

For example, 2147 is a window that is 2’1″ wide by 4’7″ long. In addition to the size of the glass pane, you need to include the measurement for the size of the total window opening, which includes the trim and frame.

The materials also play a role in determining size. Typically, vinyl is better suited to small and medium-sized windows. While fiberglass and aluminum-clad wood provide enough support for much larger casement windows.

Measurements need to be accurate to the fraction of an inch. A little too small or big will throw off the installation process and require thinking on the spot to solve the problem. This is why it’s usually best to hire a contractor to manage the window installation process, from measuring casement window size to the final seal.

Measuring New Casement Windows

Installing brand-new casement windows from scratch is definitely best left to professional contractors who have the experience and insurance—let them cut the rough opening without damaging any other part of your home, including the masonry, drywall, and electrical system.

Advantages of Casement Windows

Two of the biggest benefits of casement windows are that, like picture windows, they provide unobstructed views and bring in plenty of light. More advantages include the following:

They are Energy Efficient

They have one seal as opposed to single- and double-hung windows that have at least two sides that can allow cold air from outside to leak inside. When this happens, your heating system has to work that much harder to keep your house warm.

Furthermore, strong winds blow against the windows, putting more pressure on the seal to make doubly sure that no air gets in or out. As a result, they are better at temperature control than other windows, including awning windows.

They are Easy to Maintain

There aren’t as many moving parts as in other windows, so there are fewer components that need to be thoroughly cleaned and oiled. The way in which casement windows open also makes the glass panes easier to clean, both inside and out.

They are Stylish and Beneficial

It doesn’t matter if you choose to push or crank-style casement windows, the extent to which they open is greater than other window styles, maximizing other benefits, including ventilation and light.

They Provide Home Security

Casement windows contribute to home security. They can’t be opened from the outside. The locking mechanism is hook-shaped and inaccessible from outside the home.

Disadvantages of Casement Windows

You need to consider the bad as well as the good if you want to make an informed decision.

Not Child-Proof

They’re not as child-proof as other window types; for example, double-hung windows. The locks are easy to access from the inside, especially if the windows are low to the ground. It’s important to keep them securely locked, so there is no possibility of little fingers working them open and going for a walk.

The Length is Unsupported

This can make them more likely to break than other windows. In addition, the lack of support when the windows are wide open means that strong winds could blow them shut and break the glass as a result. The wide opening also makes them vulnerable to strong winds that could break them off their frames.

However, with proper maintenance and an eye on weather forecasts, it’s possible to mitigate the risks. For example, if the news predicts gale-force winds or heavy rain, keep all the windows closed so that they increase the pressure and strength of the seal.

Window Screens

Window screens are placed inside the window frames, which means that standard air conditioners that need to be vented outside aren’t an option.

Professional Casement Window Measuring and Installation

It’s possible for you to measure and install casement windows yourself, but only if you are extremely experienced in DIY projects in bedrooms, kitchens, and bathrooms.

As a rule, it’s always best to hire a professional company to determine casement and double-hung window sizes. Window professionals will get it right the first time and save you time and money. Contact us at 877-590-2741 at Euroline Steel Windows and Doors today!
