18x14 vs 20x20 Screen Mesh, Which One Is Right for Your Florida Home

One of the most common questions I get during estimates is about screen mesh. Homeowners hear terms like 18x14 or 20x20, but they are not always sure what those numbers actually mean or how they affect comfort, maintenance, and temperature.

I own and operate A Home Service, and my job is to help homeowners choose the screen mesh that makes sense for their home and how they use their enclosure.

What the Numbers 18x14 and 20x20 Actually Mean

The numbers in screen mesh simply refer to how many yarns run through the screen per inch.

With 18x14 mesh, there are 18 yarns running in one direction and 14 yarns running in the other direction. This creates a more open screen that allows good airflow and clear visibility.

With 20x20 mesh, there are 20 yarns running in each direction. Because there are more yarns packed into the same space, the weave is tighter.

In simple terms, higher numbers mean a tighter screen. Lower numbers mean a more open screen.

Pine Needles and Easier Cleaning

One of the biggest advantages of 20x20 mesh is how it handles pine needles. With standard 18x14 mesh, pine needles can poke through the screen and get stuck, which makes the top of the enclosure harder to clean.

Because 20x20 has a tighter weave, pine needles are far less likely to push through. If your home is near pine trees and you are tired of dealing with needles stuck in the screen, 20x20 is usually the better option.

UV Protection and Cooler Pool Areas

The tighter weave of 20x20 mesh also blocks more sunlight. This reduces the amount of UV light entering the enclosure.

In most cases, 20x20 mesh blocks about twice the UV compared to standard 18x14. That can help lower the temperature inside the enclosure and keep pool water cooler, especially during the hotter months.

For homeowners concerned about heat buildup, this difference is noticeable.

No See Ums and Bug Control

20x20 mesh is often called no see um screen. No see ums are tiny biting insects that usually come out in the evening and are common near water, canals, and salty areas in South Florida.

The tighter weave of 20x20 helps keep these insects out. Standard 18x14 mesh may still allow them through. If bugs are an issue where you live, upgrading to 20x20 can make the enclosure much more comfortable at night.

When 18x14 Mesh Still Makes Sense

18x14 mesh is still a great option for many homes. It allows more airflow, has a slightly clearer view, and works well in areas without heavy vegetation or nearby water.

If you rely on natural breeze or do not deal with insects or pine needles, 18x14 may be the right choice.

How I Help Homeowners Decide

There is no one screen mesh that works best for every home. I look at the surroundings, the layout, and how the space is used before making a recommendation.

The goal is always the same. Choose a screen that makes the enclosure easier to maintain, more comfortable to use, and better suited for South Florida living.
