A critical step in the window replacement process is measuring a window opening for new windows. Accurate measurements ensure that your new windows fit and function properly. Here’s how to measure a window opening for new windows step by step.
Step 1: Determine the width.
When you measure the width of the window opening it should always be measured at the top, middle, and bottom of the window frame. Take the smallest measurement of the width of the window opening to determined the size.
Step 2: Establish your height.
Take your measurement of the height of the window opening at the left, middle, and right of the window frame. The height of the window opening is determined by the smallest measurement.
Step 3: Figure out the depth
Take the distance between the window frame and the wall or trim to determine the depth of the window opening. This measurement is critical in determining the correct depth of the window sash.
4. Measure The Sill:
Measure the width of the window sill at the left, middle, and right of the window frame. Take the smallest measurement as the window sill width.
Step 5: Take a measurement of the jamb.
You will have to measure the window jamb at the top, middle, and bottom of the window frame. Take the smallest one as the window jamb width.
Step 6: Take a rough opening measurement.
Measure the width, height, and depth of the window frame to determine the rough opening. You will use this to determine the proper size of the rough opening for the window.
Step 7: Record your measurements.
Make a note of all of your measurements and double-check their accuracy. To ensure that you have the correct measurements, measure each window opening at least twice.
It’s important to remember when measuring for new windows that the window opening will have to be slightly larger than the window itself to allow for proper installation and expansion. Always measure the smallest dimension of the window opening and include the width, height, depth, sill, jamb, and rough opening measurements. By following this step-by-step procedure, you can ensure that your new windows fit and function properly.
