Tilt & Turn Window Sizes
Tilt and turn windows are a practical window solution for any blocks of flats and other locations that are above a storey in height.
When considering the size of a tilt and turn window, you are limited by the height to width ratio. Once the opening section becomes wider than the height, that is how wide you can go. Otherwise, you'll be placing too much strain on the hinges or there might not be enough room to open them internally.

Standard Sash Window Sizes
Sliding sash windows are a classic style of window, most often found on period properties.
Most period sash windows were built during the Victorian and Edwardian periods. At that time, the standard width for sash windows was approximately 1.2 m (4 feet). So most period sash windows fit this size.

| Inches (in) | Millimetre (mm) |
|---|
| 36 in | 914 mm |
| 48 in | 1219 mm |

Sash window sizes can vary widely, especially for any windows built before and during the Georgian era. If your property has a non-standard size window, you will require bespoke size frames to be made. At Everest, we do offer made-to-measure sash windows.

The Size of Windows in Different Rooms
Generally, rooms in the home will have windows of different sizes because the light and ventilation requirements are not the same in every room. Plus, you might have smaller windows in a bathroom, for example, to maintain privacy levels.
Bathroom windows
Your bathroom windows will most likely be the smallest windows in the house. The standard size for them will depend on which type of window they are (casement, sliding sash, etc.).
Living Room Windows
Living rooms tend to have the largest windows in the home. The lounge is one of the most frequently used rooms and often the focal point of the property, it's important for the windows to look good and allow in plenty of light. Sliding sash, bay and casement windows are commonly used for living rooms.
Kitchen Windows
The height of windows in a kitchen will differ depending on where they are located. For example, windows located above the sink are calculated by considering the height of your kitchen cabinets and the thickness of the countertop. Any windows that are fitted above a backsplash will need to consider the height of the backsplash.
Bedroom Windows
In the past 20 years, larger bedroom windows have increased in popularity.
Standard bedroom window sizes:
| Inches (in) | Millimetre (mm) |

How to Measure Windows
Always measure your windows from the outside. Use a good metal tape measure and hold it taut and make sure it’s vertical or horizontal point to point across the frame or window aperture.
Take three measurements, one in the middle and two towards the edges. Use the smallest measurement. Repeat this for the height and width.
Also, measure your windows from corner to corner to make sure they are square.
Check your measurements several times. You do not want to get these wrong.
A window needs some tolerance when it’s fitted so manufacturers will deduct between 5-10mm from measurements to make an allowance.
