5 Common French Cleat Mistakes (and How to Avoid Them)

Hello Makers…
In this guide, I’ll show you the most common mistakes DIYers make when installing French cleats and building tool holders — and how to avoid them.

I’ll walk you through my own journey, from my first attempts to a much more efficient, space-saving system. By following these tips, you’ll save time, money, and wall space.

1. Think Before You Cleat

One of the biggest questions in French cleat forums is: “How far apart should wall cleats be?”

The answer for the best French cleat spacing depends on what you’re storing:

• Small parts & consumables → Place cleats closer together (around 3–5 inches).
• Large tools or power tools → Wider spacing works fine.
• Tall items (e.g., garden tools) → You may only need one or two cleats across the whole wall.

Tip: Avoid covering an entire wall in cleats if you’ll only use a fraction of them. Plan your wall layout based on the actual tools you’ll store.

2. French cleat tips – Respect the Geometry

Design your tool holders so they fit neatly without wasting wall space.

• Decide on a small set of standard heights for holders (e.g., 4″, 9″, 14″).
• This ensures holders don’t clash when you hang them side by side.
• A small gap (say 6 – 12 mm or 1/4 – 1/2″) between holders makes them easier to remove.

Reality check: While French cleats are movable, in practice you’ll rarely re-arrange them. Designing with consistent dimensions saves headaches.

3. French cleat storage ideas – Use Slots, Not Holes

Early on, I built holders with holes for screwdrivers and chisels — but this wasted space above the tools and trapped items.

Instead:

• Cut slots in the holder base so tools can slide in and out.
• Slots free up vertical space and make it easier to store additional tools.
• For chisels, I now use small recesses with rare earth magnets to hold them securely.

4. Don’t Overbuild with Scrap

It’s tempting to use whatever plywood scraps you have — but 12 mm (½”) ply is often overkill.

I fell into this trap initially. All of my early cleats were made from 12mm ply that I had lying around. I just used expensive material because I had it. I’d have been better off buying 6mm and saving the 12mm for more appropriate projects.

• Most holders can be made from 6 mm ply, which is lighter, cheaper, and still strong enough.
• Save thicker plywood for heavy-duty holders.

5. Store the Right Tools in the Right Place – Workshop organization with French cleats

Your French cleat wall is prime real estate — reserve it for the tools you use most often.

• Identify your top 10 most-used tools.
• Place their holders above or next to your main workbench or saw station.
• This keeps your bench clear and your workflow efficient.

Example: Next to my mitre saw, I keep a speed square, tape measures, ear defenders, and a pencil — everything I need within arm’s reach.
