You may like the style your old bay window, but its condition may have deteriorated. It’s probably time to replace it with a modern bay window, but accurate measurements are vital when replacing windows. Learning how to measure a bay window takes only a few steps. You may want a partner to help hold the end of the tape measure.
How to Measure a Bay Window Steps
- Begin by measuring the widths of the two windows forming the ends of the bay.
- Place the tape measure tip on the seam between the casing trim and window frame.
- Extend tape measure until it reaches the center of the adjoining window’s joint with the window that you’re measuring.
- Record the width measurement on paper.
- Position the step ladder in a stable spot if you need help reaching the top of the window.
- Hold the tip of the tape measure at the top seam where the casing trim meets the window frame.
- Pull the tape measure to the bottom seam.
- Record the height on paper.
- Repeat this measurement process for the window on the opposite end.
- Take multiple height measurements across the bay window to ensure you have the correct height.
- To measure the center window, which is typically wider, place the tape measure at the center of the joint with the left window.
- Extend the tape measure until you reach the center of the joint with the right window.
- Record this width on paper.
- Double-check all window measurements and confirm that you wrote down the measurements correctly.
