How to Measure an Insect Screen?

The most critical step in ordering an insect screen is taking the correct measurement. A wrong measurement means the product either will not fit or will leave a gap. This guide explains the correct measuring method for windows and doors step by step.

All You Need: A Tape Measure

No professional equipment is needed for measuring. A standard tape measure is enough. Measurements are noted in centimetres (cm).

Measuring for a Window

1. Width: The width of the inner opening where the window sash sits is measured. It is measured at three points — top, middle and bottom — and the smallest value is used.
2. Height: The height of the same opening is measured on the left, centre and right. Again the smallest value is used.
3. Depth check: Clip-mounted fitting requires sufficient flat surface on the inner face of the joinery. On narrow joinery, screw fitting is preferred.

Measuring for a Door

On doors, the clear passage opening is measured:

• The inside-to-inside width of the door frame
• The clear height from the top frame to the floor (threshold included)

On pleated and sliding models, the bottom rail height is also noted.

Common Mistakes

• Taking the outside measurement: The insect screen is produced to the inner opening. The outer frame measurement is not used.
• Measuring a single point: Joinery is not always perfectly square. Measure at three points and use the smallest value.
• Calculating tolerance: The fitting allowance is not deducted from the measurement. The clear opening measurement is passed on. Production applies the tolerance.

When in Doubt

Once a photo of the joinery is sent over the WhatsApp channel, the correct measuring points are marked on the image. An on-site survey service is also available across Gebze, Kocaeli and Istanbul.

Correct measurement = trouble-free fitting. Two minutes of care prevents days of waiting.
