How to Measure a Window Opening for Replacements
Accurate measurements are key. If you mess this up, the new window won't fit, and that costs time and money. Get it right before you order.

You'll usually measure after removing the old window to expose the studs.
Here's how: Measure the width between the studs (inside edge to inside edge) at the top, middle, and bottom. Write down the smallest of the three. That's your width. Now, measure vertically from the bottom to the top (again, inside edge to inside edge) on the left, in the middle, and on the right. The smallest of those three is your height.
Common mistakes? Assuming the opening is square. It almost never is. Also, remember shims. You need a little room—about a half inch on each side and the top—for shims to make the new window square. If you measure too tight, you'll have to change the opening, which is harder. If you measure too large, your window might be too small, which could cause drafts or structural issues.
If the measurements are wrong, you'll either have to reorder (costly and slow) or force a too-big window into the opening, which might damage the window or wall.
