The Indoor
Putting Green

The decision is really about the room, not the product. If the space does double duty (living room, guest room), buy a mat: our putting mat rankings cover the field from the $30 PuttOUT trainer to full-length greens, and the good ones roll genuinely true. If the space is yours alone, put down real turf once and never think about setup again. That difference sounds small and is everything: friction decides whether practice happens.

The basement is the classic for a reason: long sight lines, hard flat floors, and nobody walks through your line at 9pm. A concrete floor is actually the ideal base for glued or loose-laid putting turf, and a 3-by-12 run along a wall out-practices most backyard builds because it's twenty steps from the couch.

The home office is the stealth winner. A 3-by-10 strip beside the desk turns hold music and think time into short-game reps. This is where pre-cut nylon turf shines: it looks intentional, almost like a rug, and a stimp 10 to 12 surface makes those idle putts real practice instead of carpet golf.

The hallway is free putting-green real estate in almost every home. Long, straight, flat: a runner-style mat or turf strip fits where no other golf equipment could. The one caveat is traffic; hallway greens work best as mats you can kick to the side.

The garage pairs naturally with a sim setup: putting turf along one wall, hitting bay in the middle. If you're already planning that room, our simulator room ideas guide shows how the pieces fit together, and the putting strip is the cheapest square footage in the whole build.

Wherever it goes, apply the same rule as outdoors: put it where you already walk every day. An okay green in the office beats a great green in a spare room you visit weekly.

Indoors, length matters more than width. The putts that decide scores live between three and ten feet, so a 3-foot-wide by 9-to-12-foot run covers the practice that matters; width only adds the ability to putt multiple lines. If you can stretch to 15 feet, lag practice becomes possible, but don't sacrifice daily convenience to get there.

On speed: indoor surfaces play consistent because there's no wind, moisture, or grain change, so whatever stimp you buy is what you'll putt every single day. That consistency is a feature for stroke-building and a small trap for feel: if your home surface runs 12 and your course runs 9, weekend lag putting will take an adjustment hole or two. Buying near your course's speed (a 10 for most public-course players) keeps practice transferable. Our turf guide covers how stimp ratings work and which fibers hold their speed.

One indoor-specific note: lighting changes how much your practice sticks. A green you can see clearly at night (a floor lamp at the hole end is enough) gets used after dinner, which for most working golfers is the only practice window that exists.

Indoors, you skip the hardest parts of a backyard green build: no excavation, no crushed-stone base, no drainage. Your floor is the base, which is why the whole job fits in an afternoon.

1. Pick the surface. Pre-cut nylon putting turf is the easy button: the All Turf Mats True Roll (3x10, stimp 10-12) at $157 goes down as-is. For bigger or custom shapes, buy putting turf off a roll and trim to fit; specs to look for are in the turf guide.

2. Deal with the floor. Concrete and hard flooring: lay the turf loose or use carpet tape; it isn't going anywhere. Over carpet, put a thin rigid underlayment (hardboard or plywood) down first, because turf over padding putts like a waterbed.

3. Add the hole. Practice cups that sit on the surface work fine and move anywhere. If you're gluing turf down in a forever spot and want a real recessed cup, a hole saw and a sleeve cup do it, but the surface cup is the sane default indoors.

4. Frame it. A timber or trim border keeps edges flat, stops balls at the wall, and makes the green read as a designed part of the room instead of sports equipment on the floor. This is the ten-dollar step people skip and then wish they hadn't.
