When installing new or replacement windows in your home, one of the first steps is accurately measuring the window openings. Many homeowners ask – should I measure the windows myself or hire a professional? There are pros and cons to both approaches that are worth considering.
Understanding how to measure windows correctly is crucial for a successful installation. Accurate measurements ensure that your new or replacement windows fit perfectly, providing energy efficiency and aesthetic appeal.
In this article, we’ll examine the differences between measuring for new versus replacement windows, common DIY mistakes to avoid, and the potential benefits of having experts handle the measuring windows for replacement process. This knowledge can help you make an informed decision and get windows that fit your needs and budget.
Difference between measuring for new and replacement windows
Measuring for new window installations versus replacements isn’t exactly the same process.
When putting new windows where there were none before, such as in a new addition or expanding existing openings, you’re working with a rough opening that needs to be precisely measured. Key required measurements are the windows size, including the width, height, and depth of the rough opening. The window unit must be slightly smaller than the rough opening to allow for shims during installation. Understanding how to measure window size correctly is crucial for this process.
| What is a rough opening? This term refers to the size of the opening in your wall where the window frame will be placed. It’s crucial to measure this space with precision. The rough opening should be slightly larger than the window frame to ensure a secure fit, but not too large. The actual window size should typically be a half-inch smaller than the rough opening. This means subtracting a quarter-inch from each side of the window’s width and height, allowing for a snug, secure installation with just the right amount of wiggle room. Remember, accurate measurements lead to seamless installations. |
For replacement windows, you need to measure the existing window frame and glass. This requires measuring the inside dimension of the frame rather than the rough opening. You want the new window to fit the existing window frame for a seamless swap. Precision is key to getting the replacement glass and frame sized correctly. It’s important to know whether to take window measurements height or width first to ensure accuracy.
The measuring process and required tools differ slightly between new and replacement window installations. New windows have more flexibility, while replacements need to be spot-on. By learning the correct techniques for measuring, you can ensure a successful installation whether you’re adding new windows or replacing existing ones.

Measuring Different Window Types
When it comes time to replace your home’s windows, proper measurements are crucial to ensure the new windows fit perfectly. However, the measuring process can vary depending on the specific window type you need to measure for replacement. Different window styles have different operational mechanisms that require accounting for particular dimensions. For example, measuring techniques for a casement window (which cranks outward) will differ from a double hung window (with operable top and bottom sashes) or a fixed picture window.
Even subtle differences in how the sash, frame, and opening mechanisms work mean measurement requirements can change from one window type to the next. Making even a small mistake during this process could result in ordering incorrectly sized replacement windows that won’t operate smoothly or insulate properly when installed.
While detailed measuring guides are available, the nuances illustrate why hiring professional window installers for replacement projects is often best. Experienced contractors understand the precise techniques needed to capture all the critical dimensions for casements, double hungs, sliders, bays, bows, and every other window style.
Many homeowners work with top window manufacturers’ certified installation partners. At OKNOPLAST, we work with top-tier window installation specialists across the USA.

Whether basic replacements or more elaborate designs, the expertise of manufacturer-trained installers provides peace of mind, your new windows will operate flawlessly for years to come.
Common mistakes to avoid when measuring windows DIY
If you decide to take DIY window measuring into your own hands, here are some common window replacement mistakes to be aware of:
- Only measuring the visible glass – The glass size won’t tell you the full frame dimensions needed. Measure inside the entire window frame.
- Measuring from the outside only – For replacement windows, interior frame measurements are most important.
- Not using a steel tape measure – material tape measures can stretch and give inaccurate readings. Opt for a steel tape measure.
- Measuring at only one point – Take measurements at the top, bottom, left and right sides, and the middle. Windows are not always perfectly square.
- Forgetting to measure window depth – This is key for new window installations to size the window projection correctly.
- Skipping the verification step – Double-check a sample of measurements to ensure accuracy before ordering.
- Mixing up measurements – Label each measurement with the corresponding window to avoid confusion later.
- Measuring alone – Have an extra set of hands to hold the tape steady for more reliable measurements.
Avoiding these common pitfalls will lead to a smoother installation and better-fitting windows. Taking your time and being meticulous is key. Don’t hesitate to re-measure several times if any doubt exists. Measure right the first time and save yourself hassles down the road.
What are the benefits of hiring professionals to measure windows?
Hiring an experienced professional to measure your windows can provide multiple important benefits over trying to DIY it. Precision is key when it comes to custom window installations.

Professionals can also identify potential issues that may complicate the installation, like windows being out of shape or requiring different framing. Their daily experience measuring a wide variety of window types means they have an eye for detail and accuracy beyond that of most homeowners.
This experience and expertise also lead to greater efficiency, allowing professionals to measure all windows in a home faster than a DIY trial and error process. At OKNOPLAST, we provide professional measurement services alongside installation for a smooth end-to-end process.
