A perfect lawn is basically a haircut with boundary issues. You mow. You admire. Thenlike a rebellious eyebrowgrass pops up along fences, pavers, and flower beds, mocking your nice clean lines.
That’s where a string trimmer (a.k.a. weed whacker, weed eater, “the loud stick”) becomes the unsung hero of yard care.
Better Homes & Gardens (BHG) tested a mix of gas and electric string trimmers at homeusing them repeatedly, edging with them, and checking how they handled real obstacles like trees, fences, and tight corners.
The five winners below cover the biggest needs most homeowners actually have in 2025: fast trimming, clean edging, big-yard stamina, budget value, and gas-powered “don’t mess with my weeds” muscle.

How BHG Tested These String Trimmers
“Best” is a big word, so BHG treated it like a science experimentwith grass. Their testers started with the basics (instructions and assembly), then moved into repeated use in normal home-yard situations.
What the testing focused on
- Ease of setup: Were the instructions readable? Did assembly take forever?
- Performance in real detail zones: Around trees, fences, landscaping borders, and tight edges.
- Edging ability: Could it run on its side and still feel stable and accurate?
- Comfort and control: Balance, vibration, how it feels during longer sessions.
- Line system: Loading the line and how smoothly the feed system worked while trimming.
- Battery reality check: Charge time and runtime for cordless models.
- Value: Price compared to performance (because “premium” is only fun when it earns it).
BHG also included follow-up impressions after months of usebecause a string trimmer that’s great on Day One but annoying by Month Six is basically a relationship red flag with a motor.
The 5 Best String Trimmers of 2025 (Full Reviews)
1) Best Overall: EGO Power+ ST1521S 15-Inch String Trimmer
If you want one cordless string trimmer that feels “just right” for most suburban yards, this is the one BHG liked best.
It’s balanced, confident around obstacles, and (praise be) makes reloading line dramatically less annoying.
Why it wins
- Automatic line loading: Feed the line through the head, press a button, and it windsno spool wrestling required.
- Fast charging in BHG testing: The battery reached full charge quickly and handled multiple yards’ worth of detail work without fading out.
- Comfortable trimming feel: A stable shaft and low-vibration brushless motor helped it feel controlled for both wide passes and precision work.
Keep in mind
- Adjusting height can be slower than you’d expect: If multiple people share one trimmer, frequent shaft-height changes may feel a bit fussy.
- Speed affects runtime: Like most cordless trimmers, max power is awesome… until the battery reminds you it’s not plugged into the sun.
Best for
Homeowners who want a cordless weed wacker that’s powerful, smooth, and low-dramaespecially if you care about fast, easy line reloads.
2) Best Budget: WORX 20V Power Share GT Revolution 12-Inch String Trimmer
This is the “starter trimmer” that refuses to act like a starter trimmer. BHG liked it because it’s affordable, adaptable, and surprisingly useful for the everyday lawn chaos most people actually have.
Why it stands out
- 3-in-1 flexibility: Converts between trimmer, edger, and a mini mower mode for those random tufts that shoot up like they’re auditioning for a nature documentary.
- Adjustable design: Easy to tweak shaft length so different heights can use it comfortably.
- Long-lasting real-life use: Even though charging can take hours, BHG found the battery lasted through multiple sessions before tapping out.
Keep in mind
- Controls can feel confusing: Buttons clustered together can make the learning curve steeper than it needs to be.
- Smaller cutting swath: A 12-inch path is great for tight spaces, but it’s not the fastest choice for big open runs.
Best for
Smaller-to-medium yards, first-time buyers, or anyone who wants a budget cordless string trimmer that can also edge neatly without buying a separate tool.
3) Best for Large Yards: Makita XRU15PT (36V / 18V X2 LXT) Brushless String Trimmer Kit
If you have a bigger property (or a yard that grows like it’s getting paid), BHG liked Makita for its efficient power use, pro-grade feel, and smart speed options.
This is the cordless trimmer that acts like it drank espressocalm when you need finesse, aggressive when you need to clear a mess.
Why it shines
- Multiple speed options: Choose lower speed for precision trimming or ramp up for thicker growth.
- Automatic Torque Drive (ADT): A mode that adjusts speed based on what you’re cuttinguseful when your yard changes moods every 10 feet.
- Reverse button: Helps clear tangled debris (which is basically the trimmer’s version of “undo”).
- Battery stamina: BHG testers reported consistent charge time and enough runtime to tackle front and back yard work without constantly swapping batteries.
Keep in mind
- Line replacement is more involved: It’s a manual process that requires disassembly and winding linenormal for many trimmers, but less fun at this price point.
- Shoulder strap fit: Very tall users may find the strap less comfortable or less adjustable.
Best for
Larger yards, frequent trimming schedules, and homeowners already invested in Makita batteries who want a serious cordless weed eater with refined control.
4) Best for Edging: Greenworks 40V 13-Inch Cordless String Trimmer
Some trimmers can edge. This one likes edging. BHG highlighted how easy it was to hold sideways and get clean lines without feeling like you’re wrestling a lawn sword.
Why it’s a great edging pick
- Lightweight: Around 5 pounds (without the battery), which makes longer edging sessions more realistic.
- Simple shaft adjustment: A clamp-based adjustment that’s quick to set to your height.
- Automatic line feed: BHG found it easy to usestop, restart at full power, and the line advances.
- Solid runtime: About 45–60 minutes in BHG’s experience, which covers most routine yard work.
Keep in mind
- Single-line system: It performed well in testing, but a single line can struggle more on thick, tough weeds compared to dual-line heads.
- No speed adjustment: One mode keeps things simple, but it’s less customizable for delicate trimming versus heavy clearing.
Best for
Anyone who cares about crisp edges along sidewalks, driveways, and bedsand wants a cordless string trimmer that’s easy to hold and not exhausting to run.
5) Best Gas: STIHL FS 91 R 16.5-Inch Gas String Trimmer
This is the “no excuses” option. BHG’s testers loved it for thick vegetation, overgrown cracks, and those stubborn areas where cordless tools sometimes politely quit.
If your yard is more “nature documentary” than “magazine cover,” this is the muscle pick.
Why it’s the best gas trimmer in the bunch
- Power through dense growth: BHG reported it sliced through thick vegetation and even twigs without hesitation.
- Precise handling: Despite being substantial, it navigated tight edges, borders, and obstacles cleanly.
- Smart ergonomics: Controls placed on one handle, plus a loop handle for maneuvering around shrubs and tight spaces.
- Comfort help included: A shoulder strap helps distribute weight, and BHG noted minimal vibration/noise for a gas tool.
Keep in mind
- Fuel mix: Requires a mix of unleaded gas and 2-cycle oil (standard for many two-stroke trimmers, but still a “read the label” moment).
- Heavier build: Around 12 poundsthis is a powerhouse, not a featherweight.
Best for
Large properties, thick weeds, heavier workloads, and homeowners who want gas-powered performance (and don’t mind mixing fuel).
What to Know Before Buying a String Trimmer
1) Power source: gas vs. battery vs. corded
Here’s the practical truth: most homeowners in 2025 are buying cordless battery-powered string trimmers because they’re quieter, lower-maintenance, and increasingly powerful.
Gas still wins on continuous runtime and heavy clearing, but it comes with fumes, more noise, and ongoing engine care.
Corded can be a solid budget choice if you don’t mind managing an extension cord (and you’re not trimming the back 40).
- Battery: Great for routine trimming and edging; check runtime, charge time, and whether the battery system matches tools you already own.
- Gas: Strong for dense weeds and long sessions; expect heavier weight and fuel/oil mixing for many models.
- Corded: Usually affordable and consistent; limited by cord reach and the hassle factor.
2) Cutting swath: faster isn’t always better
Cutting swath (cutting width) is the path the trimmer clears in one pass. Wider swaths can finish open areas faster, but smaller swaths can be better around tight landscaping and fence lines.
BHG’s top picks range from about 12 inches (tight control) up to the mid-to-high teens (faster clearing).
3) Feed system: bump vs. automatic (and why this matters)
Trimmer line shortens naturally as it hits edges, stones, and the occasional hidden sprinkler head you forgot existed.
The feed system determines how quickly you get fresh line without stopping your workflow.
- Automatic feed: Usually advances line with a button or specific restart behavior. Convenient, beginner-friendly, and great for quick sessions.
- Bump feed: Tap the head on the ground to advance line. More control over line length and often preferred for longer trimming sessions.
If you hate interruptions, prioritize easy line loading and a feed system that feels intuitive. (Your future self will thank youprobably while sipping lemonade instead of reloading spools.)
4) Weight, balance, and shaft adjustability
A string trimmer can be “light” on paper and still feel awkward if it’s top-heavy or poorly balanced.
Look for an adjustable shaft if multiple people will use itor if you want to protect your back and shoulders from becoming a cautionary tale.
Shoulder straps matter most on heavier cordless models and gas trimmers.
5) Safety isn’t optional
Debris can fly. Noise can add up. Gloves save your hands from blisters and vibration fatigue.
At minimum, wear eye protection and sturdy shoesand consider hearing protection, especially for longer sessions or gas-powered tools.
Conclusion
If you want the cleanest all-around experience, the EGO Power+ ST1521S is BHG’s top pick because it’s powerful, comfortable, and makes line loading feel almost… civilized.
For budget shoppers, WORX GT Revolution gives you multi-tool versatility without wrecking your wallet.
Big yards get along beautifully with the Makita XRU15PT thanks to efficient battery use and smart speed control.
If edging is your obsession, the Greenworks 40V is lightweight and easy to hold sideways for crisp borders.
And if your weeds are basically forming a union, the STIHL FS 91 R is the gas-powered powerhouse that doesn’t flinch.
Pick the tool that matches your yard’s personalitythen enjoy that oddly satisfying moment when everything looks sharp, tidy, and suspiciously expensive (even if it wasn’t).
Field Notes: of Real-World String Trimmer Experience
The first time most people use a string trimmer, they learn a humbling lesson: grass is politeuntil you try to cut it precisely. You start with confidence, squeeze the trigger, and instantly discover that trimming is less like “mowing” and more like “drawing a straight line with a marker while riding a skateboard.” The trick is letting the tool do the work. If you shove the head into tall weeds like you’re angry at them, the line burns down faster, the motor works harder, and the whole job starts feeling like a sweaty debate you didn’t agree to join.
A common “aha” moment is realizing how much the feed system affects your mood. With bump feed, you can keep movingtap, advance, continueespecially once you get the rhythm. But if you’re new, it’s easy to either bump too often (wasting line) or not enough (suddenly you’re trimming with a stubby little thread that’s mostly just making noise). Automatic feed can feel friendlier for beginners, but it also changes your workflow: some systems advance when you stop and restart, which means your technique becomes “trim, pause, restart, trim,” like you’re doing interval training for lawn care.
Edging is where string trimmers earn their keepand where you can tell if a model is comfortable. Turning the trimmer on its side sounds simple, but the weight distribution matters. A lighter model feels like you’re outlining the lawn with a pencil. A heavier model can feel like you’re holding a trombone at arm’s length. Wheels and edging guides help, but the real secret is short, controlled passes. Go slowly along concrete and pavers, and keep the head a consistent distance from the edge. If you rush, you’ll scalp the grass, chew the border, and wind up with a “modern art” edge instead of a crisp line.
Battery management becomes its own mini-game in 2025. If you’re already in a battery ecosystemMakita, EGO, or another platformlife is easier because extra batteries and chargers are already part of your routine. And the truth is, runtime feels longer when you work smarter. Use higher speed only when you hit thick patches; cruise on lower or variable speed for normal grass. You’ll finish faster overall because you’re not constantly restarting, reloading line, or swapping batteries. Also: if your yard is damp, everything feels harder. Wet grass clumps, strings get bogged down, and edging can turn into green confetti. It’s doablebut it’s never as satisfying as trimming dry.
Lastly, respect the tool. Even a quiet cordless model can fling a pebble with surprising enthusiasm. Eye protection is non-negotiable. Gloves make long sessions more comfortable. Sturdy shoes protect you from the weird stuff lawns hiderocks, sticks, and the occasional mystery object that definitely wasn’t there yesterday. Master those basics, and trimming stops being a chore and starts becoming that weirdly satisfying “final polish” that makes the whole yard look finished.
