What’s the ideal mesh size of a mosquito net?

Mesh size is important

The ideal mosquito net mesh size depends greatly on where it is used, but is usually between 1.2 and 2 millimeters to provide sufficient protection. The primary purpose of the mosquito net is to keep insects away from the sleeping area. Therefore, the meshes should not be so large that mosquitoes can get inside the mosquito net. On the other hand, it should allow you to sleep undisturbed. Especially in tropical regions, it is an advantage if the mosquito net allows enough air to get inside and it is not too sticky underneath. It should therefore not be too tightly woven.

WITH A MESH SIZE BETWEEN 156 AND 220 YOU ARE WELL POSITIONED FOR MOST REGIONS

The WHO (World Health Organization) generally recommends a mesh size of 156 or higher. This mesh size guarantees good protection against common mosquitoes and other insects.
Don’t worry: most mosquito nets on the market have a standard mesh size of 156 or higher, which means that there are 156 holes per square inch. A mosquito net should have at least this mesh count of 156 to provide basic protection from common mosquitoes. In areas with malaria risk we recommend this mesh size with an additional impregnation.

BEGINNER’S MISTAKE! MOSQUITO NET WITH MESH SIZE TOO SMALL (MESH number TOO HIGH)

Many travelers are under the misconception that a very small mesh size, i.e. a very high mesh count (300 +) is better, as the honeycombs are significantly smaller and therefore offer greater protection. However, this higher protection also results in significantly poorer ventilation, as the small honeycombs only allow a small amount of air exchange. And this is counterproductive, especially on warm nights. Imagine you are staying in a bungalow somewhere in Bali and it is a sweltering 28 degrees Celsius. Your mosquito net is safe, but there is no fresh air inside – the night will be anything but pleasant.

AREAS WHERE A MOSQUITO NET WITH A HIGH MESH COUNT IS REQUIRED

In areas with midges, such as Scotland, a mesh count of 300 is recommended as the midges there are very small and would get through the honeycomb of an ordinary mosquito net. You also need to worry less about ventilation here, as Scotland is not really known for hot summer nights.
