Measure a fly screen correctly

Since a fly screen is loosely stretched in a frame in almost all cases, correctly measuring it is a simple task. It is roughly cut with overhang or surcharge and is later precisely finalized. It is important to consider the type of construction and placement in order to implement the correct measurement approach.

Placement is crucial for the final dimension

The first step is to decide where the fly screen should be installed. After choosing whether to attach it inside or outside, the exact placement comes into play. The following options are available:

  • Also read - Gluing or repairing a mosquito net in the frame
  • Also read - A mosquito net doesn't stick
  • Also read - Fasten a fly screen with Velcro
  • In the frame of the window or door
  • In the reveal
  • As a front grille in the frame

All variants have a support surface that ultimately determines the final dimension of the fly screen.

An exception is jamming when attaching the frame. Here, however, the grid is also cut to size with a protrusion or an allowance.

Almost all types of construction require a protrusion

If you build a mosquito net yourself, measure the outer edges of the frame and add about two centimeters overhang in each direction. In order to be able to follow the cutting path well, an auxiliary line, which is applied with chalk, helps.

In the case of purchased and up-to-date fly grid is provided by the providers a guidance of the maximum. Often they also give a supernatant. The mostly drawn assembly steps that produce practical imagination from the theoretical task of the measurement.

Noteworthy three-dimensional factors

Since a fly screen has depth, must be thought of any disturbing elements that would drill in faulty attachment and measure through the grid. The following components are typical interference factors:


Only at outdoor assembly can it come to the conflict with a shutter. Also on the often existing two blocking tabs on the lower edge must be thought.

Sensors for thermostats

Sensors and sensors are not only in the way, but can be restricted by a fly screen in their function.

Window or door handle / fitting

Too far outstanding handles are the fly screen in the way. Either the frame is deposited or selected another mounting location.

Rain or weather legs

At the bottom frame, many windows and doors have so-called rain or weather legs. The protruding block strips can disturb due to missing or oblique bearing surfaces.
