How to Measure a Window Screen for Replacement

If you're ordering replacement window screens (or sending dimensions to us for a quote), the measurement step is where most people get it wrong. Here's how to do it correctly.

What You Need

  • A tape measure (the metal kind - not a fabric sewing one)
  • A pencil and paper
  • Five minutes per screen

Step 1: Remove the screen (if you can)

If your window screen comes out - most do, with squeeze tabs at the top or bottom - pop it out and measure the screen frame directly. This is the most accurate method.

If it doesn't come out, measure the window opening the screen sits in. Subtract 1/8 inch from both width and height for the new screen.

Step 2: Measure width to the outside edge of the frame

Lay the screen flat. Measure across the outside edge of the aluminum frame at three points: top, middle, bottom. Use the smallest of the three numbers.

Step 3: Measure height the same way

Top to bottom, on the outside edge of the frame, at three points: left, middle, right. Smallest number wins.

Step 4: Note the frame depth

This trips people up. Standard window screen frames come in two common depths:

  • 5/16 inch (most older homes, pre-1990 construction)
  • 7/16 inch (most newer homes, post-1990)

Measure the thickness of the existing frame, not just the width and height.

Step 5: Note the spline groove

Look at the back of the frame. There's a groove where rubber spline holds the mesh in place. Measure the width of that groove - it'll be either 0.135 inch (standard) or 0.160 inch (heavy-duty).

Step 6: Take a photo

Always take a photo of the existing screen - front, back, and corners.

The Shortcut

Common Mistakes

  • Measuring the window opening, not the screen
  • Forgetting to measure depth
  • Rounding up to whole inches (screen frames are sized in 1/16 inch increments)
  • Assuming all screens in the house are the same size
