Standard Window Sizes: Explained

Confused about window sizes and standard window dimensions? Read on and we’ll explain everything you need to know about sizes when shopping for windows.

Do Standard Window Sizes Exist?

First of all, let’s address the fact that ‘standard window sizes’ are actually a myth. There is no industry-wide standard sizing, especially when so many windows are custom-made for houses. Standardisation of window sizes differ between manufacturers, who will make windows in sizes that they deem to be standard. 

As windows and houses are now mass-produced, this has led to an industry-wide standard of sorts, but again, it’s at the discretion of the manufacturers to decide what they think is standard. Those “standards” will also change over time.

Standard House Window Sizes

Before we get into the broad-stroke standard dimensions for house windows, let’s explain how these sizes are specified. There’s a really straightforward system for identifying window sizes. 

Window size is noted in a 4-digit figure. The first two digits refer to width and the other two are for height. For example:

4030 = 4 feet wide and 3 feet high

So, if you want a window that’s 38 inches wide and 68 inches high, its size would be noted as 3258. You may need a inches to feet converter (and vice versa)!

This is a handy way of immediately identifying and noting sizes, making it easier for you to shop. 

If you are currently undertaking a project, or want to know the ballpark ranges of common window sizes, then here are some new construction window sizes and average window dimensions:

What’s a Standard Bathroom Window Size?

For this one, we’re going to look at two different standard window sizes. First, standard sliding window size:

Width: 36 to 84 inches

Height: 24 to 60 inches

Standard picture window size:

Width: 24 to 96 inches

Height: 12 to 96 inches

What’s a Standard Kitchen Window Size?

You’re also likely to find picture windows in kitchens – the standard sizes for that is above. Another type of window commonly found in kitchens are double-hung windows:

Width: 24 to 48 inches

Height: 36 to 72 inches

For kitchens, it’s also handy to note standard casement window sizes:

Width: 14 to 35.5 inches

Height: 17 to 73 inches

What’s a Standard Bay Window Size?

Width: 42 to 126 inches

Height: 36 to 78 inches

What’s a Standard Awning Window Size?

Width: 24 to 68 inches

Height: 20 to 42 inches

What’s a Standard Sash Window Size?

Width: 14 to 68 inches

Height: 24 to 128 inches

Things to Consider 

Window sizes are often in whole figures, but generally speaking they’ll be half an inch shorter than the specified number, as this makes installation easier. So don’t worry if your aperture is 37.8 inches high and the replacement window you want is 38 inches high. Double check with the vendor, but it should be still be fine for installation.

If your aperture will not fit a standard sized window, all is not lost. One option is to spend money on custom windows, but if you’re on a budget, this may not be viable. 

The most cost-effective thing to do is adjust the aperture so it will meet standard window sizes. This can’t always be done but if it can, it will certainly be less harsh on your pockets. Custom windows may be necessary in older homes, as they were built before windows were being mass-produced.

What Are French Casement Windows?

You may already be very familiar with casement windows, but what about French style casement windows? 

French casement windows are made up of two windows that push out beyond the envelope of your home. Typically, they don’t have a vertical post in the middle and will open out from the centre. Unlike a traditional casement window, this allows for an unobstructed view when the windows are open.

Not all windows of this type are the same, but the most common is the push out French style casement window. Inswing French casement windows are also available.

When Should You Use French-Style Casement Windows?

French style casement windows are excellent when installing a window in a large, open space such as your kitchen or bedroom. They’re not so suited to hallways, stairwells, or toilets.

As they open fully, they can let in plenty of light and air. If you have a room that enjoys a fantastic view, when opened a French window will allow you to enjoy it without obstruction.

What Are the Features & Benefits of French Casement Windows?

So, why should you opt for a French casement window? The choice is completely yours but let’s lay out some of the benefits so you can decide whether French casement windows are the right choice for you. 

  • Ventilation – French windows open out to 90 degrees plus and allow for rapid air flow into the room. You also have the choice of opening just one side if you need some ventilation, but don’t want to open the windows the whole way. 
  • Security – French window security is typically of a very high standard. They come with locks that are highly secure so you don’t have to sacrifice on safety. They also open so wide that they can also double up as a fire escape if needed. 
  • ViewsAs mentioned previously, French windows give offer unobstructed views of the great outdoors. 
  • Low MaintenanceFrench windows, especially uPVC ones, are extremely low-maintenance. A quick wipe every now and then will keep them clean, and they don’t need to be treated regularly like wood.
  • EfficiencyFrench windows offer better energy efficiency than double hung windows, whilst simultaneously providing more ventilation. 
  • VarietyWith French style casement windows, there’s plenty of opportunities for customisation and personalisation. This makes them particularly appealing to our design-minded customers.

Hardwood vs. Softwood Windows

Choosing the right windows for your home is really important. It’s not like you get do-overs (not without incurring costs, anyway). 

If you’ve decided on fitting your home with wooden windows but are confused about the differences between hardwood and softwood windows, read on.

What’s The Difference Between Hardwood and Softwood Windows?

You might be familiar with the terms hardwood and softwood, but do you fully understand the differences between them?

Hardwood timber refers to deciduous trees. Species like oak, mahogany, teak, walnut and maple are all hardwoods. They have a high density and are incredibly durable. 

Softwoods are of a lower density and come from coniferous trees like fir, pine, spruce, yew and cedar. These are generally speaking, less durable than hardwoods, although that isn’t their defining difference. 

Some hardwoods aren’t very durable at all, like balsa, which is extremely light. Yew timber, a softwood, is extremely hard-wearing. In broad-stroke terms however, hardwoods are generally more durable, and harder to mould and work with, whilst softwoods are the opposite. 

Hardwood vs Softwood Windows

Let’s get into the nitty-gritty and see how each type fares against the other in a number of categories, and examine some of the differences between hardwood and softwood that you should know about. 

How Long do Hardwood and Softwood Windows Last?

Both hardwood and softwood windows can last your entire lifetime if maintained and refurbished. There are cases of listed buildings with softwood windows that have lasted well over 150 years!

You can expect your wooden windows, especially hardwood timber, to last up to 60 years or more (some of our wooden windows come with a 40-year fungal and rot guarantee). Softwood windows are more responsive to the seasons and will expand and contract more, whilst hardwood windows are a safer bet in terms of longevity.

Although all woods are susceptible to fire damage, hardwoods are much more fire resistant than softwoods (if that is something you need to consider). 

What Looks Better: Hardwood or Softwood Windows?

It’s a dead heat in this match. Both hardwood windows and softwood windows can look equally stunning. Hardwoods give you that genuine timber feel that creates a fantastic traditional look. Softwoods tend to be more subtle and understated in appearance.

Bear in mind that softwood timber is much more workable than hardwood, giving you more flexibility in terms of carving and creating complex joints.  

Are Hardwood or Softwood Windows Cheaper?

As a general rule of thumb, you can expect hardwood windows to be up to 30-40% more expensive than softwoods. As it takes longer to grow, and is harder to harvest and then work into window frames, this is simply the price you pay for the extra cost and effort that goes into collecting and making it ready for sale. 

Softwoods are also a more sustainable option in terms of the environment. As they grow much faster, softwoods are able to be more sustainably sourced.

What Do You Call a Window That Doesn’t Open?

Don’t be fooled, this isn’t a setup to a joke. As you are probably well aware, most windows open.

Your casement windows, sash windows, hung windows; these are all commonly found windows that open up to let fresh air into your home. But what about windows that don’t open? Is it a fixed glass window? A non-opening window? A fixed pane window?

We get a lot of questions on this and some people struggle to find the fixed window they’re after because they don’t know the terminology. So, we’re going to go through some of the popular types of non-opening window you can get for your home.

So, What Are Windows That Don’t Open Called?

There are quite a few window types that do not open and they can make a really striking design feature in your home. To save yourself going to a retailer and asking ‘do you have one of those windows that aren’t really a window because it doesn’t open, but it is made of glass and looks like a window?’ – we’re here to clear things up and make shopping for windows easier.

Windows that don’t open are, generally speaking, called ‘fixed windows’ – but let’s get into the most commonly types of fixed windows, so you know exactly what you’re talking about.  

Picture Windows

Picture windows are a small window that looks much like a picture frame, offering a clear and unsullied view of the outside. These are great for letting extra light into a room that doesn’t need ventilation. They can be really large and fill an entire wall for example; or, they can be installed in say, a bathroom. Positioned high enough, no one will be able to look in but you’ll still benefit from an extra channel of light.

Arched Windows

An arched window makes an absolutely stunning design feature. These are windows with an arched top, that very rarely open or close because of the design.

However, you can get one to open like a casement window, if you want.

Arched windows are often installed above opening windows for their appearance and extra light. A good example of where arched windows are used to full effect are in large two-storey hallways. You could never reach it to open it, so a fixed arch window allows natural light to flood the home, and it looks fantastic. It also gives the space a period home feel.

Glass Block Windows

Glass block windows are used to offer privacy whilst still allowing light to filter through. These can be installed as a translucent or transparent glass block window and make a good feature for a front porch for example, or in a bathroom. You can also get a patterned design on glass block windows, making them a truly gorgeous installation.

Circular Windows

No points for guessing how circular windows got their name. Very self-explanatory, these are deployed in a similar fashion to picture windows, allowing natural light in without taking up too much real estate on your walls.

They’re also ideal for letting in extra light without sacrificing on privacy.They’ve also been used fantastically in nautical themed rooms as faux portholes.  Go even bigger for an unconventional window design that is sure to get your guests talking.

Transom Windows

transom sash windows

Transom windows are panes of glass that are installed above a door. Often in a semi-circular shape or with decorative detailing, these can really revolutionise the area around your front door.

They are also used to great effect throughout the house. They can be used for internal doors to let natural light flow between rooms, or they can be used for decorative purposes.
