Best String Trimmer Line of 2026

A string trimmer is only as good as the little coil of plastic inside it. The engine can be flawless and the grip comfortable, but if the line snaps every thirty seconds or welds itself into a bird's nest on the spool, you'll spend the afternoon swearing instead of edging. Good line and cheap line look identical on the shelf — same shape, same wind, wildly different afternoons. What a decent one actually buys you is momentum: you keep walking, the head keeps feeding, and the fence line gets done before the battery quits.

I've re-spooled a head on a tailgate more times than I care to admit, so I came in with opinions. Over the past five months my team and I ran 16 different lines through the same chain-link run, cracked driveway, and a back field that gets away from us every June. One thing I'd tell any first-time buyer: match the diameter to what your head is rated for. Thicker isn't an upgrade — it just overloads the auto-feed and bogs the motor. The picks below all kept feeding.

The quality that made this roll our default is not on the label: it is how rarely it snaps. Fence lines and concrete edging are where most line dies, and this 0.095 twisted copolymer kept cutting through both without the mid-job respool that wrecks your rhythm. It also slices tall grass cleanly instead of dragging the trimmer down into the turf and scalping the lawn.

The 200 feet arrives as ten refills, so you open one at a time and leave the rest coiled instead of fighting a bird's nest in the shed. Compatibility is the widest in this group — DeWalt 20V, EGO and Ryobi battery trimmers and the usual gas heads all take it in a 0.095-rated spool. Wind it snug and even, though: wound loose, it hangs up in the hopper, and that is a spooling mistake rather than a line fault.

Where it gives ground is the very thickest brush, where a hard square edge bites deeper into woody stems. For the mix of lawn, fence line, sidewalk and stray weed patch that most of us actually trim, this is the roll we keep reaching for, and it costs about what the mid-priced rolls here cost while carrying more feet than most of them.

Bottom line: We recommend this as the default 0.095 line for mixed lawn and fence-line work: it snaps less, feeds cleanly in most heads, and 200 feet covers a long stretch of trimming.

If most of your trimming is really edging, this is the line that shows it. The twisted square edge leaves a crisp border along a sidewalk, goes through thick stems and snakelike roots without stalling the head, and it is the most aggressive cutter in this group — which is what the higher price buys.

Echo rates it for medium to heavy weeds and builds in resistance to welding and high heat, and 253 feet makes it one of the bigger rolls here, so a normal suburban yard is not reordering in the middle of the season. It also leaves the tidiest edge on a drive, the kind of detail you notice once and then cannot unsee.

It is the roll for a trimmer with an open, forgiving head and a property with a lot of edge to it — driveway, sidewalk, chain-link, the places where a square edge earns its keep. For general mowing-duty string trimming, our top pick is the safer and cheaper choice.

Bottom line: We recommend it when edging is the main job: crisp cuts through stems and roots, in a 253-foot roll, on a head that feeds square line well.

Loading a trimmer is the chore nobody budgets for, and EGO's pre-cut pack deletes most of it: five 14-foot lengths, each already the right size for the Power+ head, so there is no measuring, no guessing and no half-wound spool to unwind in the grass.

For an EGO owner this is the reload we recommend keeping on the shelf. The fit is exact for the 56-volt 15-inch trimmer and the STA1500 attachment, the line matches the 0.095 twisted profile the trimmer ships with, and a swap takes minutes rather than an evening.

Two things to know before you commit. Seventy feet total does not go far if you have a lot of chain-link fence, and the segments can break early in heavy growth — this is convenience line, not the toughest stock here. If you want to buy in bulk instead, check that your head feeds non-EGO line before you order, because not every EGO head takes it happily.

Bottom line: We recommend this for EGO Power+ owners who want the fastest possible reload: exact pre-cut fit, minutes to install, and less line than a bulk roll.

There is nothing to wind here, and that is the entire product: three factory-wound spools that clip straight into a Black+Decker auto-feed head. Anyone who has hand-wound a spool in the wrong direction will see the appeal immediately.

For a Black+Decker trimmer, we have not found a simpler reload. The fit is right for most auto-feed heads in the range, the swap takes seconds, and three spools mean one on the trimmer, one in the shed and one you have not lost yet. The 0.065 line suits grass and light weeds around a normal suburban yard.

The system's weakness is that the spool is the feed mechanism. A spool wound badly at the factory will not auto-feed, and there is nothing you can do in the yard to rescue it — you swap it out and try the next one. That is the argument for genuine spools over a hand-wound refill, even though the refill is cheaper per foot.

Bottom line: We recommend it for any Black+Decker auto-feed trimmer: the fit is right, the swap takes seconds, and the factory wind is more reliable than hand-winding.

Round, dimpled line is unusual in a category that keeps chasing sharper edges, and the shape is the whole argument: the undulating surface is what Husqvarna credits for cutting noise roughly in half, and it is also why the line feeds past an eyelet without snagging.

Durability is where it earns its place. It does not wear fast, it takes a lot to snap, and it stands up to acreage rather than a suburban lot. The co-extruded copolymer is made in the USA, and at 0.095 it fits the same heads as our top pick. What it does not shrug off is heat — run it flat out against a concrete drive and it can weld to itself and break off at the head. That is true of most line this diameter; easing off the throttle at the curb saves more line than any product choice.

The catch is quantity. At 140 feet, this is the shortest of the full-size rolls we recommend, so it is the pick for someone who wants a quieter trimmer and a smooth feed more than the biggest stockpile. A yard with close neighbors, or a head that is fussy about square line, is exactly the case for it.

Bottom line: We recommend it for heavy residential trimming where noise and smooth feeding matter: quiet, tough, and easy on a bump head, as long as 140 feet per roll suits your yard.

Five pounds is a supply decision rather than a restock. At 1,280 feet, this roll carries more than six times the line in the 200-foot rolls here, which puts it in a different category of purchase — closer to buying a coil of fence wire than a pack of trimmer string.

The line itself is a four-edge square in hi-vis orange, extruded from nylon 66 copolymer, and it slices through thistles, blackberries and the dense growth that stalls round line. The bright color matters more than it should: a dropped coil is easy to find in tall grass.

Fit is the part to check. This line tends to sit at the top of the 0.095 spec, and heads already tight on 0.095 — some Stihl and EGO models among them — can refuse to feed it. Run a couple of feet through your head before you commit the whole roll.

If you trim an acre or more, split a roll with a neighbor, or simply hate reordering, this is the bulk buy we point people to. It is the lowest cost per foot in this group and the cutting is as good as anything here; just buy it for volume, not as the toughest line on the page.

Bottom line: We recommend it for large properties and anyone tired of reordering: 1,280 feet of sharp square line at the lowest cost per foot here.

Three hundred and thirty feet of square 0.095 line for less than the mid-priced rolls here is a straightforward deal, and on a plain bump-feed trimmer it is a cheap way to keep cutting all season. What it is not is the most consistent line in this group.

The square profile does real work: sharp edges shear through grass along sidewalks and fence lines and leave a cleaner border than round line in the same head. It is polyamide, it is orange, and it winds on without fuss as long as you keep tension on the spool.

Fit is the thing to check before you buy. Not every auto-feed head takes 0.095 happily, and some EGO trimmers will not feed this line at all. On a standard bump head it loads and runs normally, which is where this roll makes sense.

Bottom line: We recommend it as cheap, sharp-cutting volume for a simple bump-feed trimmer, and the top pick is the better buy if you edge hard against concrete.

Seven refills and a cutting tool for less than any other roll here is the pitch, and we think it is a fair one for a light-duty trimmer. Nothing about this pack pretends to be commercial stock.

The 0.080 diameter is the sensible middle for a battery trimmer: thick enough for grass and light weeds, thin enough that a 20-volt motor does not bog. The refills come as separate coils rather than one big spool, so one can live on the shelf and one in the garage, and the little cutter is genuinely useful for trimming a fresh length cleanly instead of chewing it apart.

What it is not is heavy-growth line. 0.080 handles a lawn and a tidy border; take it along a fence line of mature weeds and it is overmatched, which turns a cheap pack into an expensive afternoon spent reloading.

For a small yard and a light electric trimmer it is a sensible restock: the low cost and the included cutter are the whole point, and a spare coil in the garage means the next reload is not a shopping trip. If your property runs to fence lines and blackberries, the top pick is the roll to carry instead.

Bottom line: We recommend it as the budget restock for a light electric trimmer on a small lot: seven refills, a cutting tool, and the lowest outlay here.

How We Tested String Trimmer Line

We started by pulling every line option we could find in the diameters that cover most residential trimmers, then filtered out anything that didn't clearly state its size, its breaking strength, or what head it was designed for. That left 16 lines, from bargain refill spools to premium coils, and we ran them for five months — from the first spring cleanup through the last cut of the season. Price per foot got recorded for every one, because a cheap-looking spool isn't a bargain if it's half the length.

Every line went on the same three heads — a bump-feed, an auto-feed, and a fixed head — on a half-acre yard with a long chain-link run, a cracked driveway, and a back field that gets away from us by June. We timed re-spooling with a stopwatch, dropped each spool from waist height to see whether the coil sprang loose, and counted how many times we had to pull the head apart because the line had welded together or the auto-feed refused to advance. Cuts were judged against the same overgrown patch — clean slice or bruised, whipped grass — and along the fence, where thin line shatters and thick line stalls.

Durability came from a running count of breaks per session, plus leaving a length of every line in a hot garage and another in the rain, then checking whether it went brittle or swelled. We also noted which spools could be rewound and reused and which were sealed units you throw away whole, since that changes what a season actually costs.

How to Choose the Right String Trimmer Line

Match the diameter to the head, not the label

The number that matters is printed on the spool housing or in the manual: 0.065 for most light battery trimmers, 0.080 for general residential work, 0.095 for gas trimmers and heavier growth. Going up a size buys durability in thick stems and costs feed reliability, because oversized line rubs the guard, bogs a small motor and jams the head. Heavy duty on the package means nothing if your trimmer is rated for the size below. If you want 0.095 performance from an 0.080 machine, the honest fix is a different head.

Decide how much winding you will tolerate

Bulk rolls are the cheapest per foot and the most work. Ten-refill packs like our top pick split the difference, while factory-wound spools and pre-cut lengths cost more per foot and remove the two things that go wrong — winding direction and cut length. We think the convenience formats earn their premium for anyone who trims in short sessions, and bulk earns its keep on a large property where you reload often. Then buy the format your head actually accepts, because an auto-feed system may not give you the choice.

Round, twisted or square: pick for the cut

Square-edged line bites harder and leaves a crisper border along a sidewalk. Round line feeds more smoothly and runs quieter, and a twisted profile sits between the two. If the head is fussy or the trimmer is a quiet one, round is the safer buy. If edging is the job, a square edge does visibly better work and wears faster against concrete. Neither is better in the abstract; the trade is cut quality against feed smoothness and how much abrasive surface you trim along.

Heat kills line faster than grass does

A lot of line failures are heat rather than abrasion. Hold full throttle against a foundation wall or a curb and the tip melts into a blob and snaps at the eyelet. Let the tip do the cutting, ease off at concrete, and trim when the grass is dry, since wet clippings load the head and make the motor work harder. Do not overfill the spool either: a head packed past its capacity binds and misfeeds, and the line gets blamed for a loading mistake.

Frequently Asked Questions

Final Verdict

Our default is the MaxPower 200-foot roll: it snaps least in the work that actually breaks line, it feeds cleanly from a DeWalt 20V to a gas trimmer, and it sits mid-pack on price for more feet than most rolls here. EGO owners should take the pre-cut pack and accept fewer feet in exchange for a reload measured in minutes. Anyone trimming an acre or more should go straight to the Anleolife bulk roll. And if crisp edging is the whole point, the Echo roll cuts the cleanest of the group.
