How to Measure for a Replacement Window Screen

Ordering a custom replacement screen is straightforward when you measure the existing screen frame carefully. Use the steps below before entering your dimensions in the custom screen builder.

Important: Measure the outside edge of the existing screen frame to the outside edge. Do not measure the glass or the visible opening when you have an existing screen that fits correctly.

What you need

  • A tape measure that clearly shows 1/16-inch increments
  • Your existing screen removed from the window, if possible
  • A flat surface so the frame can lie straight while you measure

1. Measure WIDTH (Horizontal)

Measure from the outside edge of the left side of the aluminum frame to the outside edge of the right side. Record the measurement to the nearest 1/16 inch.

WIDTH (Horizontal) HEIGHT (Vertical)

2. Measure HEIGHT (Vertical)

Measure from the outside edge of the top of the aluminum frame to the outside edge of the bottom. Record the measurement to the nearest 1/16 inch.

3. Choose the fraction carefully

Our builder separates the whole-inch measurement from the fraction. For example, a screen that measures 31 7/16 inches wide should be entered as 31 for WIDTH (Horizontal) and 7/16 for the fraction.

4. Identify the spring side

Look at your existing screen and note where the standard tension springs are located:

  • Top — WIDTH (Horizontal): choose this when the springs are on the top horizontal rail.
  • Side — HEIGHT (Vertical): choose this when the springs are on a vertical side rail.
  • No Springs: choose this only when your existing screen does not use tension springs.

5. Confirm the frame and mesh

Match the frame finish and screen material to the options shown in the builder. Our current frame profile is 5/16 inch x 3/4 inch aluminum.

Precision guarantee: Precision-made to your measurements. We guarantee each finished screen will be within 1/16 inch of the WIDTH (Horizontal) and HEIGHT (Vertical) dimensions you provide. These measurements are the outside dimensions from corner to corner and do not include the tension springs.

Before you place the order

  • Measure the existing screen twice.
  • Make sure the frame is not badly bent or distorted before using it as your reference.
  • Confirm that WIDTH means horizontal and HEIGHT means vertical.
  • Confirm your spring location.
  • Review the final configuration shown in the builder before adding it to your cart.
