How to measure exterior door: A step-by-step guide to accurately measuring your exterior door

Measuring an exterior door might seem like a daunting task, but with the right tools and a little guidance, you can do it with ease. Whether you are replacing an old door or installing a new one, accurate measurements are essential for a perfect fit. First, gather your tools: a tape measure, a notepad, and a pencil. Start by measuring the width of the door. To do this, measure from the left edge to the right edge at the widest point, typically around the middle of the door. Make sure to measure in three places: the top, middle, and bottom of the door. Record the largest measurement to ensure the best fit, as exterior doors can sometimes be warped. Next, it's time to measure the height. Measure from the top of the door frame to the bottom, again taking measurements at three points: the left, center, and right. As before, record the largest height measurement. After obtaining the width and height, you should also measure the door thickness. This is usually done at the edge of the door, with a standard thickness ranging from 1 3/4 inches to 2 1/4 inches. Don’t forget to check the door swing direction as well. Stand outside facing the door; if the hinges are on your left, it’s a left-hand door. If they are on your right, it’s a right-hand door. This information is crucial for proper installation. Additionally, take note of the door frame’s measurements, including the rough opening size, which is the total space where the door will fit. The rough opening should be about 1 inch taller and wider than the door itself to allow space for shims and adjustments. Lastly, consider the type of door you want, as some styles, like French doors or sliding doors, may have unique measurement requirements. Always double-check your measurements before making a purchase to avoid errors. With these steps, you'll be well-prepared to find the perfect exterior door for your home.
