Size follows what you want to practice, not a fixed number. Each cup position needs a body of flat, evenly sloped turf around it — golf course architects treat roughly three feet as the minimum, more on any slope. A wetland buffer, lot line or the shot you want to practice can all cap how big the green gets. Settle those before the layout is final. Planning a turf installation?

[Before the layout is final](https://www.timelessgrass.com/blog/how-big-should-a-backyard-putting-green-be/#before-the-layout-is-final) ## Start with what you want to practice, not a target size “How big should it be” is the wrong first question. The right one is what you want the green to do: hold one cup for short putts, hold two or three cups so a round doesn’t repeat the same line twice, or take a full chip or pitch shot before the ball ever reaches the putting surface. Each of those answers a different footprint. A single-cup green for short practice can sit in a modest corner of the yard. A green meant to hold several cup positions at once, with a buffer of usable turf around each one, needs more room — and the room has to be shaped right, not just wide enough. ## How much room one cup position actually needs Course architects don’t size a hole location by eye. A [USGA Green Section Record article](https://gsrpdf.lib.msu.edu/?file=%2F2000s%2F2008%2F080721.pdf) on hole locations sets out the minimum condition around a cup: “the hole location should have at least 3’ around the hole (holing-out area) that is consistent in slope,” and locations sitting on any real grade should have at least 6’ of consistent slope around them. In no case should a hole sit in a tricky spot or on a slope steep enough that a ball can gather speed toward it. That 3-to-6-foot ring is the number that scales down to a backyard green. It doesn’t matter whether the green holds one cup or four — each cup position needs its own body of flat, evenly graded turf that size, clear of the others. Put two cups five feet apart and neither one gets its full ring; the layout has to give each one room. For scale, the same article frames a full-size, 5,000-square-foot course green as needing roughly 2,800 square feet of that kind of usable space to support around 14 rotating hole locations over the life of the green. A backyard green built for two or three cups doesn’t need anywhere close to that much area — but the underlying idea carries over directly: count the cup positions you actually want, multiply by the ring each one needs, and that’s the floor for the green, before you add anything for the shot coming in. ## Slope eats into the number before you start Not every square foot of green counts toward that floor. The same source puts a number on how much slope a hole location can sit on at all: “any slope 3% (1.7 degrees) or greater on a 10’ Stimpmeter reading is too steep for hole use,” and the Green Section’s longstanding advice caps the main body of a green at roughly that same 3 percent grade. That matters most on a lot with real contour, which describes a fair number of yards in this part of Florida. A green built on a slope steeper than that can still be a green — it just can’t put a cup anywhere on the steep part. If the plan calls for three usable cup positions and half the intended footprint turns out too steep to qualify, the green either grows to make up the difference or the cup count comes down. Better to find that out before the layout is drawn than after. ## What the lot itself can cap Space and slope aren’t the only ceiling. If the lot backs to a pond, creek, marsh or the river system, the edge of the green may not be a free choice. In St. Johns County, the [Land Development Code](https://www.sjcfl.us/wp-content/uploads/2024/01/Article-IV.pdf) sets a natural, planted buffer next to contiguous wetlands and the St. Johns, Matanzas, Guana and Tolomato Rivers — 25 feet as the general rule, 50 feet next to those named rivers, measured from the jurisdictional wetland line — and then adds a further 25-foot setback beyond the buffer itself. Landscaping is named among the uses allowed inside that setback zone, but the buffer stays natural; it isn’t turf, planted or otherwise. A green planned toward a pond or wooded edge in a community like [World Golf Village](https://www.timelessgrass.com/northeast-florida/world-golf-village-fl/) or [Julington Creek Plantation](https://www.timelessgrass.com/northeast-florida/julington-creek-plantation-fl/) needs that line checked before the far edge is set, not after. A lot without water on the property line still has a real edge — the setback from the house, a pool deck, existing trees, or the fairway sightline some of these communities ask homeowners to keep clear. None of that has a single number that applies everywhere; it’s specific to the address, which is exactly what the free visit is for. ## What a professional install handles We measure the yard and check the ground on a free visit, then draw a [custom putting green layout](https://www.timelessgrass.com/services/putting-greens/) sized to the cup positions and shots you actually want, for you to approve before anything starts. That includes shaping the base so each cup sits on the flat, consistent grade it needs and the break lives in the parts of the green built to carry it, not the holing-out area. From there we prep the site, build a base suited to your soil, lay, seam and edge the turf, add infill and finishing, clean up, and walk you through the care it needs. ## Before the layout is final 1. **Count the cup positions you want available at once,** not moved mid-round. 2. **Give each one its own 3-to-6-foot ring** of flat, evenly sloped turf, per the Green Section’s minimum. 3. **Decide if you want a chip or pitch shot landing on the green,** which adds to the footprint beyond the putting surface itself. 4. **Check whether the lot backs to a wetland, pond or named river**, and where that buffer and setback fall on your property. 5. **Flag any sightline, tree or drainage feature** the community asks you to keep clear. 6. **Bring all of it to the estimate**, so the layout you approve already accounts for it.

At least three feet of flat, evenly sloped turf around the hole, according to a [USGA Green Section Record article](https://gsrpdf.lib.msu.edu/?file=%2F2000s%2F2008%2F080721.pdf) on hole locations — six feet where the surrounding grade has any slope to it. That's the minimum for one cup to putt to comfortably. A green meant to hold several cup positions at once needs that much room around each one, without them overlapping. ### Does the whole green need to be flat? No, and it shouldn't be — slope is what makes putts interesting to play. But the same [Green Section article](https://gsrpdf.lib.msu.edu/?file=%2F2000s%2F2008%2F080721.pdf) puts the workable limit at 3 percent, about 1.7 degrees, for any part of the green where a hole can actually go. Steeper ground still counts toward the green's footprint, it just can't hold a cup. ### Can a putting green run right up to a pond or wetland? Not all the way, in St. Johns County. The [Land Development Code](https://www.sjcfl.us/wp-content/uploads/2024/01/Article-IV.pdf) sets a natural buffer next to wetlands and named rivers — 25 feet as the general rule, 50 feet next to the St. Johns, Matanzas, Guana and Tolomato — plus a further 25-foot setback beyond it. Landscaping is named as an allowed use inside that setback; the buffer itself stays natural. Check your lot's jurisdictional line before the green's edge is set. ### Does a bigger green mean more usable cup positions? Generally, but not one-to-one. On full-size course greens, the [Green Section article](https://gsrpdf.lib.msu.edu/?file=%2F2000s%2F2008%2F080721.pdf) notes that once the number of fair hole locations drops below seven or eight, the green becomes less enjoyable to play. That comes from cups crowded too close to each other or to steep ground, not from square footage by itself. ### What should I decide before the size is final? How many cup positions you want available without moving one mid-round, whether you want room to practice a chip or pitch landing on the green rather than just putts, and whether the lot backs to a buffer or setback that caps the edge. Bring those to the estimate. ## Related turf questions - [How fast should your backyard putting green roll?](https://www.timelessgrass.com/blog/how-fast-should-a-putting-green-roll/) - [How do you care for a backyard putting green?](https://www.timelessgrass.com/blog/putting-green-care/) - [Putting Green or Chipping Green: What Changes Underfoot](https://www.timelessgrass.com/blog/putting-green-or-chipping-green/) ## Where to go next - [Putting greens](https://www.timelessgrass.com/services/putting-greens/) - [Turf in Northeast Florida](https://www.timelessgrass.com/northeast-florida/) Useful links - [Jerry Lemons, USGA Green Section Record (July–August 2008): Putting Green Speeds, Slopes, and Non-Conforming Hole Locations](https://gsrpdf.lib.msu.edu/?file=%2F2000s%2F2008%2F080721.pdf) - [St. Johns County Land Development Code, Article IV, Sec. 4.01.06: Environmentally Sensitive Areas - Wetlands, Estuaries, and Natural Water Bodies (effective 11 Aug 2025)](https://www.sjcfl.us/wp-content/uploads/2024/01/Article-IV.pdf) Free estimate ## Planning a turf installation?
