How roll width, blade direction and yard shape decide where they fall, and what to check." url: https://www.timelessgrass.com/blog/where-artificial-turf-seams-go/ updated: 2026-09-12 --- Costs and planning # Where will the seams go in my artificial turf? * * * Updated 2026-09-12 The short answer ## Where will the seams go in my artificial turf? Seams go wherever one piece of turf meets the next. Turf is typically made in rolls a nominal 15 feet wide, so any area wider than that in both directions has at least one seam, and corners, curves and cut-outs add more. Seams are commonly glued to seaming tape underneath and fastened down. Where they fall is decided on the layout drawing, so ask to see every seam marked before you approve it.

[Before you approve the layout](https://www.timelessgrass.com/blog/where-artificial-turf-seams-go/#before-you-approve-the-layout) ## A seam is where one roll meets the next Artificial turf is made in long rolls. When your lawn is bigger than one piece, two pieces are joined, and that join is the seam. The width of the roll decides most of it. The Synthetic Turf Council, the industry’s trade association, says turf is made in panels or rolls “typically a nominal 15 feet wide.” Its specification charts list widths from 12 to 15 feet. So the number to plan with is the width printed on the product sheet for your turf. Two simple rules follow: - **Narrower than the roll in one direction?** The area can be covered in one piece, with no seam. - **Wider than the roll both ways?** It will have at least one seam. The goal is as few seams as the space allows, and tight ones. The Defense Department’s guide specification for playground surfacing puts it plainly: seams “must be the minimum necessary and must be tight.” For synthetic turf it asks for rolls “as wide as practical for the installation” ([UFGS 32 18 16.13](https://nibs-s3-wbdg3-production.s3.us-east-1.amazonaws.com/FFC/DOD/UFGS/UFGS%2032%2018%2016.13.pdf)). That document is written for playgrounds on military sites, not home lawns, but the aim it states is the one to hold a layout to. ## Which way the rolls run changes the count Take a plain rectangle, 40 feet long and 25 feet wide, and turf that is 15 feet wide. - **Rolls run the long way.** Two widths cover the 25 feet, with 5 feet trimmed off. You get one seam, 40 feet long. - **Rolls run the short way.** Three widths cover the 40 feet, again with 5 feet trimmed off. You get two seams, each 25 feet long: 50 feet of seam in all. Same yard, same turf. Turning the rolls adds a second seam line and 10 more feet of join. If a piece has to be longer than the roll it is cut from, a seam across the end gets added too. Few yards are clean rectangles, but this sum is the first step on every layout. It is also why two layouts for the same space can look quite different on paper. ## The lean of the blades sets the direction Turf blades lean one way. That lean is called the nap, or grain. [North Carolina’s landscape contractor rules](http://reports.oah.state.nc.us/ncac/title%2021%20-%20occupational%20licensing%20boards%20and%20commissions/chapter%2028%20-%20landscape%20contractors/chapter%2028%20rules.pdf) require turf to be rolled out “with the nap facing a consistent direction.” That rule has a knock-on effect for seams. Every piece in the lawn has to lean the same way. So a leftover strip can’t simply be turned sideways to fill a gap. It can only go where it will lie the same way as the pieces around it. In practice, picking the nap direction picks the direction of every long seam. That is a decision for the drawing, before anything is cut. ## Yard shape adds the rest A rectangle gets its seams from roll width alone. Most of the extra seams in a real yard come from its shape: - **Inside corners.** An L-shaped lawn wrapped around a patio needs either a join near the corner or a larger piece cut to the shape, with the offcut used elsewhere only where its nap lines up. - **Curves and beds.** A curved border is cut out of the roll. A long curve that spans more than one roll width crosses a seam along the way. - **Areas the turf has to avoid.** Local rules can move the edge of the lawn, and every new edge means more cutting. Thornton’s [2026 turf rules](https://www.thorntonwater.com/wp-content/uploads/2026/02/2026-residential_artificial_turf_info__rules-1.pdf) for its water-wise rebate keep turf three feet from property lines (at the front, it may run to the line if a three-foot buffer separates it from the sidewalk) and from the trunk of any deciduous tree, and outside the dripline of any evergreen. [Florida’s standard](https://flrules.org/gateway/readFile.asp?sid=0&tid=30839130&type=1&file=62-308.100.doc) for single-family lots of an acre or less, new on 19 May 2026, keeps turf out of tree drip lines unless a certified arborist certifies it won’t harm the tree, and requires access to the septic tank for routine pumpout. That is why a [residential turf](https://www.timelessgrass.com/services/residential-turf/) layout starts with the edges, then fits the rolls inside them. ## How a seam is joined and held down The trade association describes two ways to join turf: glued with a supplemental backing material, or sewn with high-strength thread. When glue is used, a fabric seaming tape sits under the backing on both sides of the join. An industrial adhesive bonds the turf to that tape. The council lists urethane, epoxy, hot-melt and water-based latex adhesives, and says they should resist water, fungus and mildew. For lawns, the council’s buying guidelines for landscape turf tell you to get confirmation of the seam adhesive: one formulated for synthetic grass, with proven weather resistance, and usually not sold in home supply stores. Local rules can add more: - **Thornton** requires seams glued rather than sewn, with the turf held down at seams by the pins or nails its manufacturer recommends. The rebate application asks for receipts that include seaming materials. - **Florida** requires turf anchored at its edges and seams firmly enough, at a minimum, to withstand wind or flooding. Fasteners do not replace weight. The same landscape guidelines advise against using landscape spikes in the middle of the lawn in place of infill. How close should the two sides sit? For field turf, the council says seam gaps should be minimal and uniform. That means no wider than the tufting gauge on tufted infill systems, and no more than 1/16 inch on others. ## Walking routes, views and putting lines None of these documents says where in your yard a seam has to go. That part is a layout choice, and you get to make it before work starts. Three things are worth checking on the drawing: - **The route you walk every day.** Think back door to gate, or the dog’s track along the fence. The council suggests inspecting seams at least once a year, and says one that opens may need quick, temporary gluing until the installer can correct it. A long seam down your daily path is one you will be watching. - **The view you look at most.** Stand at the kitchen window, the back door or your patio chair with the drawing in hand. Ask where the seams fall in that view, and whether turning the rolls moves them. - **Places where seams cross.** The council’s testing guidance tells field testers to avoid spots where two glued seams cross. Ask whether your layout has any crossings, and where they are. On a [backyard putting green](https://www.timelessgrass.com/services/putting-greens/), add the cups and the putts you take most often to that list. The council’s landscape guidelines note that they may not apply to putting greens, so ask for the green’s own product instructions. ## Before you approve the layout 1. **How wide does this turf come?** 2. **Which way will the blades lean, and which way will the rolls run?** 3. **How many seams, and how many feet of seam?** How would that change if the rolls turned? 4. **Where does each seam sit** against your daily path, the gate, the dog’s route, your main view and any cups? 5. **Do any seams cross?** 6. **How are the seams joined and held down?** Ask about the tape, the adhesive and the fasteners. 7. **Does a local rule apply,** such as Thornton’s rebate rules or Florida’s standard?

The Synthetic Turf Council, the industry's trade association, says turf rolls are typically a nominal 15 feet wide, and its specification charts run from 12 to 15 feet. Check the width on your product sheet. Anything wider than that in both directions needs at least one seam. ### Are turf seams glued or sewn? Either, according to the trade association's guidelines, which describe seams glued with a supplemental backing material or sewn with high-strength thread. Some local rules choose for you. [Thornton's 2026 turf rules](https://www.thorntonwater.com/wp-content/uploads/2026/02/2026-residential_artificial_turf_info__rules-1.pdf) require every seam to be glued, not sewn. ### How tight should a turf seam be? For field turf, the trade association says seam gaps should be minimal and uniform. On tufted infill systems the gap between fibers should not exceed the tufting gauge. On other systems it should not exceed 1/16 inch. Those figures come from its sports field guidelines, so ask what the maker of your turf specifies. ### What should I do if a seam starts to open? Keep people off the spot and call the installer. The trade association says a seam that opens or comes loose may need quick, temporary gluing until the installer can inspect and correct it. Thornton's rules list looseness at seams among the things regular maintenance must fix. ### Does it matter which way the turf is laid? Yes. [North Carolina's landscape contractor rules](http://reports.oah.state.nc.us/ncac/title%2021%20-%20occupational%20licensing%20boards%20and%20commissions/chapter%2028%20-%20landscape%20contractors/chapter%2028%20rules.pdf) require turf rolled out with the nap, the lean of the blades, facing a consistent direction. Because every piece has to lean the same way, that choice also sets which way the long seams run. ## Related turf questions - [Putting turf on a basement or garage concrete floor](https://www.timelessgrass.com/blog/artificial-turf-on-a-concrete-floor-indoors/) - [Artificial turf or sod: which fits your yard?](https://www.timelessgrass.com/blog/artificial-turf-vs-sod/) - [What happens to your backflow preventer and irrigation meter after turf?](https://www.timelessgrass.com/blog/backflow-testing-and-irrigation-meters-after-turf/) ## Where to go next - [Artificial lawns](https://www.timelessgrass.com/services/residential-turf/) - [Putting greens](https://www.timelessgrass.com/services/putting-greens/) - [What License Does a Turf Installer Need?
