How to Measure a Window in Toronto

Measuring a window might seem like a simple task, but doing it right is important. Whether you are replacing old windows or getting new ones installed, having the correct measurements helps avoid delays and extra costs. Windows come in many shapes and sizes, so this guide will walk you through the steps using clear explanations. If you prefer, Everest Windows and Doors is a trusted local option in Toronto for windows and doors sales, service, and installation, and they can provide expert assistance whenever you need it.

Getting Ready to Measure Your Window

Before starting, gather a few tools. You will need a sturdy tape measure that can reach across the window frame, a notepad or device to record your numbers, and a level to check if your frame is perfectly straight. Measuring widths and heights more than once helps make sure your numbers are accurate. Keep in mind that window frames might not always be perfectly square, especially in older buildings common in Toronto. This means measuring at different points can help find the smallest width or height, which is often the safest number to use when ordering windows.

How to Measure Window Width and Height

Start by measuring the width. This means measuring across the window from one side of the frame to the other. To do this, place your tape measure inside the window frame, right against the wall surface or trim where the window stops, and extend it across to the other side. For accuracy, measure at the top, middle, and bottom parts of the window frame. Use the narrowest measurement you get for ordering your replacement window. This helps make sure the new window fits well without forcing or gaps.

Next, measure the height of the window. Take your tape measure from the bottom of the window frame (where it meets the sill) straight up to the top inside of the frame. Like with width, check the height on the left side, center, and right side of the window. Again, use the shortest height measurement to ensure the replacement window can fit smoothly.

Checking the Depth and Window Type

Depth is important when choosing new windows to ensure the window unit will properly fit inside the wall. Measure from the inside surface of the wall to the outside edge of the frame or to the outermost part of the window cavity. This measurement shows how thick or thin your window opening is.

You should also determine the type of window you have since this affects the kind of replacement window required. Is it a single-hung, double-hung, casement, slider, or sliding window? Identifying the style helps when discussing options with suppliers or professionals. If you find it tricky to figure out, Everest Windows and Doors provides helpful resources about different window types and services in Toronto.

Tips to Avoid Common Mistakes

A common error when measuring windows is not measuring enough times or not accounting for the frame properly. Windows in older Toronto homes might have uneven frames or small gaps. Always use a steel tape measure rather than a cloth one, as the cloth tapes can stretch and give false numbers. Writing your measurements down right away prevents mix-ups later on.

Remember, it’s safer to measure in millimetres or centimetres for better precision rather than inches. Also, when you take your measurements, don’t measure the glass itself; focus on the frame size. If your window has any trim, you may want to remove it carefully to get more accurate frame dimensions, but only if you’re comfortable doing this safely and legally.

Using Your Measurements When Ordering New Windows

Once you have the correct measurements, it’s time to use these numbers when shopping for replacement windows or getting estimates. Keeping your measurements handy helps when discussing options at places like Everest Windows and Doors, where you can explore different styles and materials that suit your home’s needs and style. They offer expert advice on what will work best given your exact measurements and preferences.

Consulting a professional can save time and avoid mistakes that cost money in the long run. If you feel unsure about reading your measurements or choosing the right product, it’s a good idea to reach out to Everest Windows and Doors in Toronto for help with sales, service, and installation. Their team understands local building standards and can recommend the best windows based on your measurements and location.

Measuring a window properly is the first step toward improving your home’s energy efficiency, appearance, and value. Make sure to take your time, double-check each measurement, and don’t hesitate to use the local expertise available through trusted companies.

Types of Windows

If you are experiencing any of the problems listed above, it may be time to get new windows. But the question is, which windows are right for you? With so many to choose from, it can be difficult to make a decision.

In this section, we will review the windows that are available so that you can make an educated choice.

Awning windows lift out from the bottom of a window to open at a 45-degree angle. The angle works to protect the home from rain and other elements. They also provide the ultimate in airflow making them ideal for kitchens, bathrooms and other areas that are prone to mold and mildew due to humidity.
To ensure your awning windows are doing all they can to boost your energy efficiency while protecting your household, be sure to look for features like multi-point locking systems and fusion welded corners that will keep out water and air. A multi-chamber construction is also recommended for its ability to increase thermal efficiency, while providing insulation, durability and noise minimalization.

Casement windows have a crank that allows them to open to a 90-degree angle. The opening provides optimal airflow within interiors.
Triple sealed panes and an optimal number of internal air chambers will ensure the ultimate in energy efficiency while keeping the elements out. An advanced locking system is also recommended for providing safety and security.
casement window

Double slider windows have two panes that move along a track. They open on either side to overlap each other to let air in. They can also fully open into the house to make cleaning easy and provide ultimate air flow. Their ability to provide ventilation makes them ideal for humidity hotspots such as kitchens and bathrooms.

Sliding windows with optimal internal air chambers will be ideal for providing thermal efficiency and insulation.
single and double slider window

Double hung windows feature one pane under another. Both panes can be moved up or down on the track to allow the window to open from the top or bottom.

Double hung windows are a popular design and a favorite among homeowners. Elegant updates in recent years have made them a trendy option for homeowners. A multi-chamber construction will further provide structural integrity.

Because the windows have a flat exterior, they are ideal for patios, walkways and other areas that may be impeded by windows that open outwards.

Single slider windows are a variation of double slider windows. Like the double slider variety, they open by sliding along their track, however, they open from one side only. If you like sliding windows, they are a more affordable option.

When low-E or low emissivity, glass is used, it results in the emission of low levels of radiant thermal energy. When combined with a krypton gas insulation, these windows can achieve optimal energy ratings.

single slider window

Single hung windows vary from double hung windows in that only the bottom pane will move when opening the window. They provide a classic style that works well in most interiors.

For the ultimate in energy efficiency, look for windows with a multi-chamber construction and an Energy Star rating.

End vent slider windows have a fixed pane in the middle and two sliding windows on either side that move inward toward the center open. They are a good alternative to double slider windows that are better suited to smaller spaces. They also make a good option for those looking for a cost-effective alternative to casement windows.

In most cases, the middle pane will release to open inward to make for easy cleaning while letting in some much-needed fresh air.

Picture windows are stationary windows that don’t open. Rather, they are meant to let light in, provide a view and work as a decorative element within the home. They are often paired with other types of windows like fixed casement, double hung or side slider.
