The 8 Best String Trimmers of 2026

Every yard has a strip the mower can't reach: along the foundation, under the fence rail, around the mailbox post. That's the strip a string trimmer is for, and it's where the difference between a good tool and a frustrating one shows up fast. A trimmer spends more time in the air than a mower does, so weight and balance matter more than the power number on the box.

We spent eight months with 12 string trimmers — gas, battery, and 2-in-1 models that convert to edgers — running them through the same two yards, including a slope behind my garage that has killed cheaper tools. We cared about power in tall weeds, real battery life, and whether the line fed cleanly mid-cut.

One thing I'd tell anyone shopping: the trimmer you'll actually use is the light one, so don't trade a pound for a spec you'll never notice. And a 2-in-1 is only worth the money if the conversion takes seconds with gloves on — some did, and some had me hunting for a pin. That single detail ended up deciding more than one spot on this list.

The 8 Best String Trimmers of 2026

BLACK+DECKER LST136 40V Best Overall

BLACK+DECKER 40V MAX 13 in String Trimmer Edger Cordless with Adjustable

The dial on top of the LST136's handle is the small thing that makes this the trimmer we hand most people. PowerCommand lets you choose between maximum power for thick weeds and maximum runtime for a long stretch of fence, on the same 40-volt pack, and that choice is what turns a 13-inch trimmer into one tool for both the tidy front lawn and the rough ground behind the shed. At 7.8 pounds with an 8,500 rpm motor, it is the best all-around balance of muscle, weight, and price in this group.

The cut holds up where it matters. The POWERDRIVE transmission carries enough torque to take knee-high weeds without stalling, and the 13-inch swath is wide enough to clear a border in a pass without making the head clumsy around fence posts and mailbox legs. Converting to an edger is a twist of the shaft, quick enough that you do it for a single sidewalk instead of saving the job for a separate tool.

Charging is the quiet win: a full pack in two hours or less, and a state-of-charge indicator on the battery so you know whether there is another pass in it before you start. The telescoping pole and adjustable auxiliary handle let you set the length once and stop thinking about it, which matters more as a session goes on.

Where the money goes elsewhere: on a half acre with a long fence line, the EGO ST1623T earns its premium with a wider cut and a head that loads itself. On a small lot, the LST300 or the WORX does the same work for less. For the ordinary in-between yard, a driveway, a hedge line, and a few tree rings, this is the one.

Worth Noting

  • Two-year warranty, half of EGO's five
  • Rotating-head edging is less crisp than a wheeled guide
Our Verdict

For a normal suburban lot, this is the trimmer we point to first: real power, 7.8 pounds, and a dial that trades runtime for muscle when the weeds win.

EGO POWER+ ST1623T Best for Large Yards

EGO POWER+ 16" Cordless Weed Trimmer with Battery and Charger

Large properties

Field Score 90/100
Weight
7.5 lb
Runtime
Up to 60 minutes
Power Source
56V lithium-ion battery
Cutting Swath
16 in.
View on Amazon

Reloading line is the chore that sends more people back to gas than any other, and the ST1623T is built around ending it. Feed the line through the head, press a button, and PowerLoad winds it; Line IQ then watches the line and feeds it as it wears, holding a full 16-inch swath without a single bump on the ground.

The working numbers back it up: up to 60 minutes on the included 4.0Ah pack, a digital variable-speed selector for the difference between tidy grass and a ditch bank, and 0.095-inch line that stands up to heavier growth than the thin stuff on cheaper trimmers. The carbon fiber shaft telescopes to fit a tall user without hunching, which is the sort of thing you notice at the end of an hour rather than at the start.

Two things to weigh, and neither disqualifies it for the right buyer. The battery sits forward and you feel it: at 7.5 pounds with the 4.0Ah pack on board, this is a trimmer that wants a strap for long sessions, and smaller-framed users will notice the nose weight before the first pack is half gone. It is also the most expensive trimmer on this page by a wide margin.

For a property with a long fence line, a ditch bank, and a couple of hours of trimming a week, that trade makes sense, and this is the trimmer we reach for when there is real ground to cover. For a quarter-acre lot, the BLACK+DECKER LST136 does the same job for much less money.

Worth Noting

  • Nose-heavy once the 4.0Ah pack is on
  • The priciest trimmer in this group
Our Verdict

The best performer here on power and reloading: 16 inches, up to 60 minutes, and no bumping, for anyone with serious ground and the budget for it.

WORX WG163 Best for Edging

WORX 20V 12" 2-in-1 Cordless String Trimmer & Electric Lawn Edger

Crisp lawn edges

Field Score 89/100
Weight
5.5 lb
Line Feed
Push-button command feed
Power Source
20V, two batteries included
Cutting Swath
12 in.
View on Amazon

Two batteries, a charger, and a wheeled edger conversion for less than the BLACK+DECKER LST136. That is the WG163's opening argument, and for a yard where the sidewalk is the main event, it is a persuasive one.

The wheels are why it earns a slot. Clipped onto the head and walked along a driveway, they hold a straighter line than any trimmer you rotate by hand, and the 90-degree tilting head reaches under a shrub or along a slope without making you crouch. The 20V motor is the mildest in this group, though: it will clear a foot-tall patch of weeds, but it wants the top speed held and a second pass on anything woody.

At 5.5 pounds it is the lightest full-size trimmer here, and the push-button command feed saves the bump-and-curse routine entirely, with WORX's free-spools-for-life program taking some sting out of the line bill. Recharge pace is the annoyance, since packs sit on the included charger for hours, so the two batteries in the box are not a luxury, they are the plan.

Worth Noting

  • 20V motor bogs down in heavy weeds
  • Packs take hours on the included charger
Our Verdict

Buy it if your yard is defined by edges: the wheeled guide and tilting head cut a cleaner sidewalk line than anything else here for the money.

BLACK+DECKER LST300 Best Lightweight

BLACK+DECKER 20V MAX String Trimmer and Edger 2 in 1

Field Score 88/100
Speed

Weight
5.7 lb
Power Source
20V lithium-ion battery
Cutting Swath

View on Amazon

This is the trimmer for the person who gave up on gas. At 5.7 pounds it is light enough at the head that it does not drag your shoulder down after ten minutes, quiet enough for a Sunday morning, and simple enough to start with a trigger rather than a cord. For a small lot, a retirement yard, or anyone with a wrist that has opinions, we think it is the best pick here.

The 12-inch swath is a deliberate trade. It means more passes along a long border, but a smaller head is easier to place around flowers, fence posts, and the gas meter, and less likely to eat a shrub you meant to keep. The automatic feed spool handles line without bumping, and the 2-in-1 conversion covers the walk to the curb.

The included 2.0Ah pack is small, and a big yard will empty it before the job is done, so plan on a spare or two shorter sessions. Because it runs on the same 20V packs as BLACK+DECKER's drills and blowers, that spare is often already sitting in the garage.

Worth Noting

  • Small 2.0Ah pack limits runtime
  • 12-inch swath means more passes
Our Verdict

The light, quiet one: best for a small yard or a weak grip, and honest about its limits on anything larger.

DEWALT DCST922B Best for Storage

DEWALT 20V MAX* XR String Trimmer

Tight storage

Field Score 87/100
Weight
9.2 lb
Storage
Folding hinge
Power Source
20V battery (tool only)
Cutting Swath
14 in.
View on Amazon

A hinge in the middle of the shaft is the whole idea here. The DCST922B folds down short enough to lie across a truck bed or stand in the corner of a shed, which is the difference between a trimmer you keep handy and one you stop using because hauling it out is a project.

The rest is DEWALT's usual approach: a 14-inch swath, a variable-speed trigger with two ranges so you can run slow along the flowers and wide open in the rough, and a brushless motor that will take on thick growth. At 9.2 pounds it is the heaviest trimmer in this group, and the mass sits where you would expect, out at the cutting head.

It is a bare tool, so the figure on the page is only the start: you need 20V MAX packs and a charger, and without them the total climbs past the complete kits here. With them already in the truck, this is the trimmer that earns its space, and the folding shaft is the reason it comes out more often.

Worth Noting

  • Bare tool, so packs and charger cost extra
  • 9.2 pounds, the heaviest here
Our Verdict

The one for DEWALT 20V owners with a tight shed: it folds away, cuts like a gas trimmer, and needs packs you probably already have.

Husqvarna 122C Best Gas

Husqvarna 122C

Fence lines, acreage

Field Score 86/100
Engine
22 cc, 2-cycle
Weight
6.9 lb
Line Feed
Tap N' Go head
Cutting Swath
17 in.
View on Amazon

Gas still has one argument nothing else answers: you can keep going. The 122C carries a 22cc two-cycle engine, a 17-inch cutting width that is the widest here, and 6.9 pounds of trimmer, with Smart Start and an air purge bulb to shorten the cold-start ritual and a low-noise engine that will not leave your ears ringing.

For a fence line that runs a quarter mile, a ditch bank cut twice a year, or a property where the nearest outlet is a hundred yards away, this is the trimmer worth buying, and the curved shaft makes it easy to steer around posts and trees. The trade is the routine: mixed fuel, a primer bulb, a pull cord, and an engine that wants fresh gas and a clean air filter every season.

Cold starting is where a small two-stroke shows its temper, so a unit that will not stay running is the thing to test in the first week, while the two-year warranty is doing the work. The Tap N' Go head feeds line with a tap on the ground, and replacement spools are cheap and sold everywhere.

Worth Noting

  • Mixed fuel, priming, and pull starts
  • Seasonal engine upkeep and fresh fuel
Our Verdict

The gas pick: 17 inches, no runtime ceiling, and light for a two-stroke, so buy it for acreage and accept the fuel ritual.

CRAFTSMAN CMCST901M1

CRAFTSMAN V20 String Trimmer and Lawn Edger Kit with 4Ah Battery and Charger

Budget runtime

Field Score 85/100
Runtime
Up to 63 minutes
Power Source
20V, 4.0Ah battery included
Cutting Swath
13 in.
View on Amazon

Sixty-three minutes is the runtime CRAFTSMAN puts on the CMCST901M1, and it comes from a 4.0Ah pack rather than from a bigger motor. That is the right trade if the problem you are solving is finishing the back fence before the battery quits, rather than clearing a hedge row.

The 13-inch swath and turn-to-edge conversion cover the basics, the handle adjusts for height, and the battery and charger are in the box. Two caveats worth knowing before you commit: the runtime figure assumes a lower speed setting, so run it flat out in wet spring grass and the minutes come off quickly, and CRAFTSMAN's claimed 52% gain over the model it replaces still leaves this a weed wacker that prefers grass to brush.

What holds it out of a top slot is simply time. This is the newest design here, and the trimmers ahead of it have been leaned against shed walls for years. If the longest claimed run time in this group is what you are shopping for, and the battery comes in the box, that is a fair bet to make.

Worth Noting

  • Runtime shrinks fast above the low speed
  • Newest design here, shortest history
Our Verdict

The runtime buy: a 4.0Ah kit with the longest claimed run time here, best for a mid-size yard and grass rather than brush.

EGO POWER+ ST1502SA

EGO POWER+ 15" Cordless Weed Trimmer with Battery and Charger

Entry to EGO

Field Score 84/100
Weight

Runtime
Up to 45 minutes
Power Source
56V, 2.5Ah battery included
Cutting Swath

View on Amazon

Five years of coverage is the longest warranty on this page, and it sits on the least expensive way into EGO's 56V platform: a 15-inch trimmer with a 2.5Ah battery and a charger in the box.

The working numbers are sensible rather than spectacular. Up to 45 minutes on that pack, a 50-minute recharge with the included charger that is quick enough to top up over lunch, and a variable-speed trigger for the difference between edging and clearing. The 15-inch swath is wider than most here without making the head awkward between shrubs.

The Rapid Reload head is where patience runs out. Threading new line through it takes more fiddling than the button-and-wind PowerLoad system on the ST1623T, and at 7.4 pounds the tool is noticeably nose-heavy once the battery is on. Neither is a reason to walk away; both are reasons to know what you are buying.

For most people who want EGO's battery platform and its warranty without the flagship price, this is the sensible EGO. Pay the premium for the ST1623T only if reloading line is the chore you hate most, or if your property is big enough to want the wider cut.

Worth Noting

  • Rapid Reload head is fiddly to rethread
  • 7.4 pounds and nose-heavy
Our Verdict

The value EGO: a five-year warranty and a 15-inch cut for far less than the flagship, with a reload head that takes some patience.

How We Tested the String Trimmers

We started with the trimmers that keep turning up in owner reviews and on store shelves, then filtered by shaft type, cutting width, battery platform, and the price of replacement batteries and spools. That left 12 units, which we ran for eight months, from the first spring growth through fall cleanup, across two yards: a flat suburban lot with a long chain-link fence and a sloped yard with a retaining wall and a strip of weeds that comes back every two weeks.

Every unit got the same treatment. We weighed each one on a kitchen scale with the battery in or the tank full, then ran a 20-minute session along fence line and foundation and noted where it pulled in the forearms and shoulders. We timed batteries from full charge to cutoff in heavy grass and ran gas models through a full tank without stopping. For line feed, we ran each head down to the nub and watched how the next length came out — bumped, fed automatically, or wound by hand.

We converted every 2-in-1 into edger mode with work gloves on, timing the swap and noting whether it needed a twist, a lever, or a tool. Power was judged in the same overgrown patch for all 12, so we could compare what each unit did rather than what it promised. At the end of eight months we checked housings for cracks, bump heads for wear, and priced replacement spools so we knew what the second year of ownership would cost.

How to Choose a String Trimmer

Start With the Power Source

Three answers, each solving a different problem. A corded trimmer runs as long as you do, weighs less, and costs the least, but you are managing an extension cord around trees and staying within reach of an outlet, which is fine on a small city lot and miserable along a fence line.

Battery trimmers have taken the middle: 20-volt models suit small yards, while the 40- and 56-volt tools carry a wider swath and a longer charge. Gas is still the answer where the work is long and the outlets are far, and we keep one gas pick here for exactly that buyer.

Swath and Line Feed Matter More Than Watts

A 12-inch head slips between shrubs; a 16- or 17-inch head clears a border in fewer passes but is heavier and clumsier around posts. The head matters as much as the swath: bump feed is cheap and works, push-button command feed is easier, and the self-loading systems on the EGO trimmers take the chore out of reloading entirely.

This is also where most frustrations start. Line that over-feeds, stops advancing, or welds itself onto the spool in summer heat turns a ten-minute job into a half-hour one, so buy for the head and keep spools matched to the unit rather than winding on whatever line is in the garage.

Weight Is the Spec You Feel

Everything here runs from about 5.5 to 9.2 pounds, and the number that matters is where the mass sits. A battery mounted forward at the cutting head makes a trimmer feel heavier than its spec sheet, and a shoulder strap fixes most of it once you pass eight pounds.

If trimming leaves your shoulders sore rather than your back, buy lighter instead of more powerful. The LST300 and WG163 exist for that buyer, and neither gives up much on a normal lot.

Batteries, Bare Tools, and the Platform You Own

A kit with a battery and charger is the right buy the first time. After that, bare tools are the cheap way into a brand: the DEWALT here comes without a pack, which only makes sense if 20V MAX batteries are already in your garage.

Amp-hours buy runtime, not power, and charge time varies widely between models, from about fifty minutes on one charger to a couple of hours on another. Check that before you decide a second battery is optional.

Edging and Storage Decide How Often It Comes Out

Trimmer-to-edger conversion earns its keep if you edge weekly. A wheeled guide, like the one on the WORX, holds a straighter line along a driveway than a head you rotate and carry freehand, and a tilting head reaches under shrubs without making you crouch.

A folding or telescoping shaft is the difference between a weed wacker that fits in the shed and one that leans against it. Neither feature adds much to the price, and both change how often you reach for the tool.

Frequently Asked Questions

Final Verdict

The BLACK+DECKER LST136 is the trimmer we recommend to most people: 40 volts, 7.8 pounds, and a dial that buys back runtime when the weeds get thick, all for less than the EGO kits. It is the least dramatic tool here and the one that will suit the most sheds.

Go elsewhere when the job changes shape. The EGO ST1623T for a big property and anyone tired of reloading line, the WORX WG163 for a yard defined by its sidewalk edges, the Husqvarna 122C where a cord or a battery never reaches.
