How to Correctly Measure Your Windows: A Step-by-Step Guide
While measuring your windows may appear to be an easy job, acquiring the exact measurements is critical for a smooth replacement process. Whether you are an experienced DIYer or a first-time homeowner, learning how to properly measure your windows and doors can save you time and unnecessary costs on your next project. We will walk you through the process of measuring your windows accurately in this step-by-step guide. Everything from recognizing your window type to measuring the width and height of your window will be covered. Updating your windows and doors may improve both the energy efficiency and the visual appeal of your home. Nevertheless, before you can realize the benefits, you must precisely measure your windows and doors.
Determine your window type
Understanding the type of window you have is critical when replacing windows. Before collecting measurements, you must first decide if your windows are single- or double-hung, casement, slider, or any other design. This information can help you in taking accurate measurements for your new window.
Single-hung and double-hung windows are the most popular types of windows seen in homes. These windows feature two sashes, one or both of which may be moved. Casement windows, on the other hand, are hinged on one side and open and close like a door. Slider windows open and close horizontally, whereas awning windows open outward from the bottom. Understanding what kind of window you have can also help you grasp the distinct characteristics of each window design.
Check for square
Once you know your window type it is essential to ensure that the corners of your existing window frame are square. This is essential because standard window sizes vary, but all windows have 90-degree corners. By checking your windows for square alignment, you can avoid potential problems when it comes time to replace your windows or install new screens or storm windows.
To check your windows for square alignment, you'll need a tape measure and a steady hand. Stand inside your home and hold the tape measure in the top right corner where the horizontal and vertical window trim meet. Extend the tape measure diagonally to the lower left corner where the trim meets and record the measurement. Now, measure from the upper left corner to the lower right corner. If the two measurements are within 1/4-inch of each other, most standard replacement window sizes will securely fit in your window opening.
However, if your window is not within 1/4-inch of square, you may need to square up the frame or find an alternate replacement solution. Refrain from letting this discourage you though, with the right tools and techniques, you can ensure that your replacement windows fit snugly and securely, providing you with the comfort and energy savings you need.
Measure window width
To begin, the dimensions of windows are presented as width by height. When measuring, it is essential to measure the width of the window from the inside jamb on both the left and right sides in three different places, the bottom, middle, and top. Jambs are the main vertical parts forming the sides of a window frame. Be sure to also exclude any trim from your measurements.
To measure the jamb at the bottom of the window, raise the window sash. Then, place a tape measure horizontally between the inside jamb on the left and right sides. Close the window and make a similar measurement from jamb to jamb near the middle of the window. Finally, measure the distance between the jambs at the top of the window. Record the shortest measurement, and this is your window opening width. It is crucial to measure each window individually, even if two windows in the same room appear to be the same size. One slight difference in measurement can lead to a poorly fitted replacement window, causing leaks or other issues down the line. For accurate measurements, each window should have its own specific measurements and be marked accordingly for future reference.
Measure window height
Assessing the window's height is just as important as measuring its width. Take three measurements to establish the right height for the new window. These dimensions should be taken from the top horizontal board above the window (head jamb) all the way down to the bottom sill. One measurement on the far left, one on the far right, and one in the center of the window is required.
However, it is important to remember that the sill is the horizontal board on which the bottom of the window sash sits when the window is closed. It is crucial to point out that the sill is not the horizontal trim board that runs across the room. Many people call that board the "windowsill," but it's actually the "stool" of the window. To measure the height of the window sill, open the window. After you have all three measures, make a note of them and circle or highlight the shortest one. This is because the height of the new window will be determined by the shortest measurement.
Measure window depth
One measurement that many overlook is the depth of the window, and for good reason. In most traditional homes, window depth is not an issue, and replacement windows fit perfectly without any complications. However, if the depth of the window is too narrow, it can be challenging to find a replacement window that fits correctly. This is especially true for mobile homes and modular homes, where the window depth is often narrower than usual.
When choosing replacement windows, the depth measurement may not be included, so it may be up to the homeowner to measure it correctly. To determine the depth of the window, one must open the window and measure the sill space from the trim in the front to the trim in the back. The minimum space required for a replacement window to fit correctly is 3¼ inches. If the depth is narrower than this, it may be challenging to find a suitable replacement window.
Round down your measurements
You have measured all of your windows and noted the shortest measurement for each one. there is one more thing you should do before selecting your new replacement windows. The highlighted measurements must be rounded to the closest 1/8 of an inch as it is critical to ensuring a flawless fit for your new windows. You must first locate the fraction of an inch in your highlighted measurements in order to round down to the closest 1/8 of an inch. If your measurement is 32-15/16 inches, for example, the fraction of an inch is 15/16. Next, locate the nearest 1/8-inch fraction that is less than the fraction of an inch. In this situation, the nearest 1/8-inch measurement is 78.5. As a result, you must round the measurement down to 32 7/8 inches. It is worth noting that if your initial measurement is already in eighth-inch increments, you may not need to make any adjustments. These final figures will be used when selecting your new replacement windows. Correct rounding ensures that your new windows fit tightly, lowering the chance of air leaks and heat loss.
When it comes to window and door replacement, proper measurement is critical. Obtaining accurate measurements guarantees that your new windows and doors will fit perfectly, look fantastic, and perform well. As we have seen in this step-by-step approach, measuring windows involves knowing what kind of window you have, properly measuring the width and height, and taking into account any unique features of your windows. If you have any questions or need assistance, do not hesitate to contact a professional. They can offer experienced advice and direction to ensure that your replacement windows and doors are the correct match for your home.
