If you’re going to install replacement windows, it pays to measure windows correctly the first time and avoid the headache of placing an incorrect order.
How to Measure Windows 101:
- Always measure the entire window, not just the glass! This includes the frame and trim as well as the window glass. Record your measurements to the nearest 1/16 inch.
- When recording measurements, follow the format “width by length.” For example, a window that is 63 inches wide and 27 inches long is recorded as “63 x 27.” A window that is 37 inches wide and 55 inches long is recorded as “37 x 55.”
- Measure windows width from left edge to the right edge.
- Measure windows height from top edge to the bottom edge.
