When I bought my first hitting mat, I picked the cheapest one and didn't think twice. Ten months later my left elbow ached after every practice session, and worse — I'd developed a swing flaw I couldn't see, because the mat was hiding it from me. Thickness isn't a spec sheet detail. It's the difference between practicing your real swing and practicing a swing that only works on a forgiving surface.
Why thickness changes your practice
Here's the physics nobody tells you: a thin mat lets the club dig through to the hard floor underneath, which does two things. First, it jams the clubhead into the ground, and that shock travels up the shaft into your elbows and wrists — hit enough balls and you'll feel it for days. Second, it punishes fat shots, which sounds good, but actually it punishes them too early in a way that teaches you to flip the club to avoid the ground, and that's a whole different swing flaw.
The three thicknesses I've practiced on
10-12mm thin mats
The classic budget mat, and honestly the $24.99 3-piece set I started with is fine for putting and short chips. The problem is full swings: the turf gives almost nothing, so a slightly fat shot slams into the floor. You start standing off the ball and scooping to protect your joints, and your divot pattern turns into a joke.
20-25mm mid mats
This is the sweet spot for most home setups. The $36.99 velvet mat sits in this range and it's the one I recommend for daily reps — it has enough give that a normal swing feels natural, and the velvet surface gives you swing path feedback in the form of scuff marks, which I've used to fix my over-the-top move. It won't save you from a real fat shot, but it also won't teach you to fear the ground.
30mm and up
This is where things get interesting. The $99.99 5x4ft mat is 31mm thick — a proper driving range feel — and here's the honest catch: a mat this thick can hide fat shots completely. The club bounces off the turf instead of digging, so your bad contact still looks okay on video. That's why I pair it with path feedback drills rather than relying on feel alone.
What I learned about my own fat shots
This is the humbling part. On the thin mat, my fat shots were loud and obvious, so I developed a habit of flipping my hands to avoid the floor. When I moved to the 31mm mat, the fat shots disappeared from the feel — but my path marks showed I was still coming in steep. The mat wasn't making me better, it was just making my bad contact look less bad.
The fix was to use both: thin feedback for honesty, thick for full-speed reps. The velvet mat tells me when I'm steep; the thick mat lets me swing freely without wrecking my joints. Together they cover the two jobs a practice surface actually has.
My thickness cheat sheet
- Putting and chipping: any thickness works — the $24.99 set is plenty
- Daily feedback reps: the $36.99 velvet mat, for the path marks
- Full swings, indoor: the 31mm $99.99 mat, with a rug or foam under it if you're on a hard floor
- Full swings plus ball tray: the $105.99 version — the tray keeps the feed moving so you don't break rhythm
The test I'd run before you buy
Here's my advice: don't buy a mat you haven't hit on. If that's not possible, at least put it on the floor you'll actually use — a mat that feels fine on carpet can feel brutal on concrete. Take ten full swings, then check your elbows the next morning. That's the test that matters.
Thickness won't fix your swing, but the wrong thickness will hide your mistakes and hurt your joints while it does it. Get the surface right, and every rep you take counts for something.
