How Much Weight Can A French Cleat Hold: A Short Guide

French cleats can save a lot of time and space. It’s also super strong. But there are multiple variables that determine cleat’s carrying capacity. That’s why you’ve to know about them before making a final decision. 

So, how much weight can a french cleat hold

French cleats are famous for being space sufficient and extremely strong. A strong french cleat can hold up to 200-300 pounds. But it’s mostly about materials and fasteners. For example, plywood can bear more weight than metal. Also, the mechanical fasteners can add up to 500 pounds without any issue. 

Anyhow, that was a quick glance at the entire discussion. There are a lot of calculations and factors to consider and take into account.

What Is A French Cleat?

French cleats let you hang cabinets, and many other things on the wall. It’s a very renowned technique from the medieval era. 

The origin of the name “French Cleat” is actually unknown. However, many people believe it comes from frenching. Frenching means cutting something into thin straps; like french fries! 

But the most logical way to assume would be that it was invented by French people. The influence of the French was massive, so it makes perfect sense. 

How Does A French Cleat Function

How Much Weight Can A French Cleat Hold

How does a french cleat function? Questions like this are very common. Just like how much wood is equal to 1 ton of coal? To understand them you’ll need to know the science behind them. 

A French cleat has a 45-degree cut. There are two cleats; tool cleat and wall cleat. The latter is screwed to the wall stud. Then the tool cleat sits on the wall cleat with tools. 

The point where the object sits is called a pivot point. The closer the point is, the stronger the cleat will be. 

If the tool cleat is sitting vertically, it won’t cause any damage. Because the weight itself is being backed up by the wall. 

Just imagine a triangle where one side is connected. The hypotenuse below backs up the weight. 

Why Should You Use French Cleat?

There are a lot of benefits you can have by installing french cleats. Let’s have a look at them below- 

Space Management

Space management is a common issue if you’re living in a small house. The small and medium rooms can benefit a lot from these cleats.

Usually, the nails are prone to come off or get weakened before the cleat. 

What Makes A French Cleat Extremely Tough

There are multiple factors that make french cleats stand out among others. The weight carrying capacity of a french cleat depends on these factors. They are material types, glues, and mechanical fasteners. 

So, to know how much weight can your french cleat carry, you should know these factors-


The material being used as french cleat matters a lot. It has to be tough and durable. Just like how finishing matters a lot for wooden coasters. Because if it fails, the entire cabinet will fall down. 

There are mainly 3 types of material used for the cleat. We’ve highlighted the weight-holding capacity of both-

Now, let’s learn the details-

Metals are the least strong that are used as cleats. They are super good for keeping light things. They are also super cheap too. 

On the contrary, plywoods are super dense and tough. They are also very durable and can stay intact for a long time. They hardly get sheared. 

People also use MDF as french cleats. But they are comparatively weaker than plywood. They’re also cheaper than plywood. 

Speaking of materials, here are some of our best recommendations for plywood french cleat-

Glues are very important for making sturdy holders. Without strong glue, you won’t be able to keep heavy things. 

Epoxy is a great adhesive to use. They are quite strong and usually lasts for 2-3 years without any nails. Silicone adhesives and wood glues are also great alternatives. 

You’ll also need some nails to carry even more weight. Using a nailer will help a lot. 

Mechanical Fasteners

A mechanical fastener is used to join multiple objects. Remember to use construction-grade screws as fasteners. This way your french cleat will be able to carry more weight. 

There are multiple sizes of fasteners. Among them, we recommend using size 6 screws and size 8 screws. 

A size 8 fastener is really good for connecting the plywood to the wall stud. When multiple of them are connected, they can carry up to 500 pounds. 

As for the connecting holders, size 6 screws are enough. They can carry around 250 pounds of pull weight. Together, these screws make the cleats extremely strong. 

Speaking of fasteners, here are top picks-
