How To Measure and Install Single Hung Window Screens

Typical Single Hung Half Window Screen

Single Hung Window Insect Screens normally covers only the bottom half of the window.

Measuring the Window Screen "Height"

Top Window Screen Channel

First check for a U-Shaped Channel at the Top (Under the window center bar).

You should find a U-Channel that may be 3/8" to 1/2" deep.

This is where the top of the screen with Leaf or Tension Springs will slip up into.


Bottom Window Screen LipNow Check for a Lip at the bottom of the window straight below the top U-Channel.

Note that this particular window has 2 lips on bottom, so find the right one if yours has 2.

You should find the Lip may be only 1/16"" to 3/16" deep (Not as deep as the top).

This is what the bottom of the screen will slip behind to hold it in place.


Measuring Window Screen HeightPut the end of a metal measuring tape all the way into the Top U-Channel and hold it as straight down as possible.

IMPORTANT: The hook on the metal tape must be small enough to go all the way into the top U-Channel.

  1. Make sure the measuring tape is all the way up into into the Top U-Channel.
  2. You should measure to 1/16"-1/8" Above of the Top Edge of the Bottom Lip.
  3. Provide measurements to the nearest 1/16".
  4. This measurement is your window screen 'Height'.

IMPORTANT: The concept is that when you insert the insect screen up in the deep Top
U-Channel, it has to be short enough to clear the top edge of the Bottom Lip, then the springs push the screen down into place behind the lip.

Measuring the Window Screen "Width"

  5. This measurement is your window screen 'Width'.
