Whether you're replacing old doors or installing new ones, getting the dimensions right prevents costly mistakes. In this guide, we'll walk you through the process, including tips and tricks to ensure accurate measurements.Understanding Door Frame MeasurementsStart by measuring the door frame, which includes the height and width. Use a tape measure to get the total width from one side of the frame to the other. For height, measure from the top of the frame to the bottom. Always measure at three points: the top, middle, and bottom for width, and the left, center, and right for height. This ensures you account for any irregularities.Measuring for Door ThicknessNext, measure the thickness of the existing doors. Standard French doors are usually 1 3/4 inches thick, but variations exist. To measure, simply use the tape measure on the edge of the door. Knowing the thickness is essential for selecting the right hardware and ensuring the doors fit snugly in the frame.Consider the Sill and Surrounding SpaceDon’t forget to measure the door sill and any surrounding space. This includes the height of the sill and the width of the area where the doors will swing open. Adequate space is necessary to prevent obstruction and ensure smooth operation. Additionally, consider the style and design to maintain aesthetic coherence with the rest of your home.Tips for Accurate MeasurementsAlways use a level while measuring to ensure accuracy. When in doubt, double-check your dimensions and take notes. If you're not comfortable doing it yourself, hiring a professional can save time and effort. Remember, precise measurements lead to a better fit and enhance the overall look of your space.FAQWhat should I do if my door frame is irregular?If your frame is not square, measure the frame's diagonal corners.
