What Size Putting Mat Do You Need?

Before you pick a length, measure two things: the floor you can spare, and the distance of the putts you keep missing. 

What size putting mat do you need? It comes down to those two numbers — not the price tag, and not whichever box looks most impressive.

Most golfers get this backwards. They buy the longest mat they can afford, can’t find room to stand behind it, and it ends up rolled in a closet.

So start with the room and the goal. The mat is the easy part.

Total Length Isn’t the Length You Putt

A mat’s advertised length is not the putt you actually get.

The cup, the back edge, and any ball-return ramp all eat into it.

A 9-foot PrimePutt gives you about an 8-foot putt.
A 15-foot model gives 14.

PuttOut is the worst offender — its “12-foot” Large mat leaves only about 10 feet of real rolling distance once the end trap takes its cut.

So buy a foot or two longer than the putt you actually want to practice. If you want a true 10-footer, you’re shopping for a 12-foot mat, not a 10.

That single fact saves more buyer’s remorse than any other on this page.

Measure the Room, Not Just the Mat

A mat needs more floor than its own length, because you have to stand and stroke from behind the ball.

A good rule of thumb: room length ≈ mat length + 2 to 3 feet for your stance. So a 13-foot mat really wants about 15 to 16 feet of clear floor. A hallway usually swallows an 8-to-10-foot mat and not much more.

Width and ceiling barely matter. Most strip mats are about 1.5 feet wide, and a putting stroke has almost no backswing, so ceiling height is never a problem. Floor length is the only real constraint.

One more thing depends on your space: what’s under the mat. If your only spot is carpeted, the surface can matter more than the length — that’s its own question, covered in what is the best putting mat for carpet.

Measure your space before you buy so you don’t end up with a mat that won’t fit.

Match the Length to the Putts You Miss

Beyond fitting your room, the length you pick also determines which putts you can train.

Short mats, 8 to 10 feet, train the makeable range and your mechanics. That’s not a downgrade — it’s where amateurs lose the most strokes. From 3 to 6 feet, average golfers hole around 48% of putts versus roughly 70% for scratch players. That gap is what a short mat trains.

But know the limit. A 10-foot mat will sharpen your 5-footers. It won’t fix your three-putts.

Three-putts come from distance control, and the lag putts that cause them start from 20, 30, even 40 feet — distances a 10-foot mat can’t reach. If speed and lag are your real weakness, you need a 13-foot mat at minimum, and ideally longer. Use that length the way our guide to how to use a putting mat effectively lays out: a distance ladder, not just short straight putts.

Pick the length that trains the putts costing you strokes.

So What Size Should You Buy?

For most home golfers, the default is simple.

Get a 13-foot mat if you have about 15 feet of floor — it’s the standard size, long enough for both distance work and short putts. Drop to a 10-foot mat if space is tight; you’ll still groove mechanics and makeable putts, just not lag. Go to a 26-foot mat only if you’re serious about speed control and have a basement or garage for it.

This is why we point people to the Wellputt: it comes in a compact 10-foot, the standard 13-foot, and a full 26-foot distance mat, so you can match the length to your room and your goal instead of compromising. The 13-foot is the one most golfers should buy.
