My analysis considered each trimmer’s type, cutting width, handle length, weight, and other crucial details.
Let’s cut to the chase and find the right string trimmer for you.
Dewalt 20V MAX String Trimmer
Best Cordless String Trimmer
Take your string trimmer anywhere when you choose a cordless option like the Dewalt MAX. Not only are there no cords or need to plug it in, but this power tool is extremely easy to transport.
It has a folding hinge, so you can easily fold it and pop it in the back of your car. The folding mechanism decreases the length by about 40 percent, making it very quick and easy to store anywhere.
What We Like
14-Inch Cutting Capacity
This was built with a 14-inch cutting capacity in mind. This allows you to cut a wider area at once, which saves you time in the long run. Get through jobs much quicker with a wider cutting capacity.
Variable Speed Trigger
This comes with two-speed settings, so you can make changes where necessary. The higher one is more powerful, which is great for thick brush. The lower one is less powerful but saves battery life if you need to get around a larger area before recharging.
QuickLoad Spool Design
It’s now easier than ever to load the spool, thanks to the QuickLoad Spool design. This makes it quick and easy to replace the 0.080-inch line.
Easy To Fold and Store
The most nifty thing about this unit is that it folds up so you can easily store it, whether that’s on a garage shelf or in the back of your car.
What We Don't Like
Not for Heavy Duty Work
While the high speed can get through some thick brush, it’s overall not a heavy-duty trimmer. Don’t mistake it for a gas option. If you have a large yard with lots of areas that need to be trimmed, this may not be the best option for you.
Poor Balance
Some customers found that the balance of this string trimmer was poor. The design means it’s a bit heavy towards the motor, and the weight isn’t evenly balanced. In fact, for a cordless trimmer, this is about double the average weight, coming in at 10.5 pounds.

Black + Decker 20V Max String Trimmer
Most Versatile
This Black and Decker string trimmer is super versatile, even if you go for the basic option. That model alone allows for both trimming and edging. This 2-in-1 tool is just the thing you need for sprucing up your garden and making it super neat.
However, if you’re looking for even more versatility, this has many extra options available. Whether you’re looking for a leaf collection bin, extra batteries, a sweeper, a hedge trimmer, or a replacement spool — there are lots of add-ons available.
What We Like
Converts To Edger
Trimmers and edgers are different tools, but buying both can be expensive. If you like the sound of a 2-in-1 trimmer and edger, check out this product.
You can easily and smoothly switch to the lawn edger without interruptions. Now, your yard will look neater than ever before.
Two-Speed Control
Take control of this power tool with the two-speed control. This allows you to boost power where needed, which is good for bigger and thicker jobs. You can decrease the speed again when you want to save battery life.
EasyFeed Technology
The EasyFeed is just the technology you need for feeding the spool without interruptions. You can easily advance the string line by pressing the button — and that’s it. No other faffing around is required.
MicroTexture Grip Handle
Something to note is that you need to hold the trigger button down during use. But to increase your comfort, this unit has a comfortable and soft handle to ease the pain.
What We Don't Like
Light Duty Maintenance Work
If you’re looking for a heavy-duty trimmer that can spruce up a neglected lawn, then this isn’t the right product for you. This is best for light-duty maintenance work only.
Top Tip
Constant Trigger Holding
A significant drawback to this string trimmer is that you must constantly hold down the trigger button. You don’t just turn it off and on as you need. This led to hand fatigue for many customers.

Personal Perspective
Black + Decker BESTA510 String Trimmer
Best Lightweight String Trimmer
If my suggestions sound like they might be too heavy for you, then this is one you might want to consider. It only weighs 6.3 pounds, so it’s lightweight, easy to lift, and transport wherever you need!
Your comfort has been a top priority in creating this product. Besides its light weight, it also has an adjustable handle so you can change the height position. This product stretches from three to four feet, depending on what feels best for you.
The adjustable height is super convenient and allows you a more comfortable experience where you really feel in control of the power tool.
What We Like
Automatic Feed Spool
This string trimmer features an automatic feed spool, which allows you to continue working without interrupting your flow to feed the spool. It does it automatically for you.
Doubles as Edger
I love that this is a 2-in-1 trimmer and edger. Both tools are important for maintaining a neat yard, so it’s super handy to find a power tool that features both.
It’s so easy to switch between the two models, too. Just rotate the machine, and it will quickly switch between trimmer and edger.
Cord Retention System
The cord retention system is super handy to have. Iwish all string trimmers featured this!
It allows you to store the cord easily when you’ve packed up your string trimmer for the day. But it also prevents you from accidentally disconnecting the cord while you’re working.
6.5-Amp Motor
This powerful 6.5-amp motor is fantastic for getting through thick and tough weeds and grass. If you have stubborn overgrowth that you want to battle against, you’ll appreciate this power.
What We Don't Like
Spool Runs Out Quickly
I recommend ordering some extra spools to keep you going. Customers noted that the spools ran out quickly, with some of it even being wasted, so it’s smart to have a few extra rolls on standby. These must be purchased separately.
Not for Tall People
Although the telescoping shaft allows for flexibility, it’s a bit too short for tall people, even at the longest height. Even those of average height, around 5 feet, 7 inches, found it too short, and they had to hunch to use it.

Ryobi ONE+ Battery String Trimmer
Best Electric String Trimmer
Electric string trimmers are a top choice because they are better for the environment. They’re also quieter, more budget-friendly, and lighter. This electric trimmer goes the extra mile by being electric cordless since it’s battery-operated.
The battery lasts for a good while, too, with many customers reporting up to an hour between charges. Just keep in mind that if you use it on the higher power settings with accessories, it may only last 12 minutes.
What We Like
Jet Fan Blower Included
If you’re looking for a versatile tool, this is an awesome option since it comes with a jet fan blower and a trimmer.
This blower runs at 100 miles per hour with a CFM of 280, so it’s very powerful and quick to use. It’s also lightweight at 5.7 pounds, so you can use it for long periods of time without tiring.
Variable Speed Trigger
With two speed settings, you get more control over how you want to use the string trimmer. This allows you to switch up depending on the task at hand. But it also lets you save battery life when needed since the lower speed setting drains the battery slower.
Pivoting 90-Degree Head
The head on this power tool pivots at a 90-degree angle. This allows you more flexibility over the tool. But it also swings out so you can achieve easy walk-behind edging, which many customers prefer.
Adjustable String Width
Adjust the string width from 11 to 13 inches, giving you ultimate control over your cuts. This is especially important for more delicate spots.
What We Don't Like
Jamming Issues
While most customers were satisfied, a few experienced the trimmer getting jammed quite easily. If you’re taking down tall or thick grass, you may experience jams.
Low Battery on High Power
As mentioned, the battery can drain quickly when you use the higher power settings or additional attachments. It can last up to an hour on regular settings but as little as 12 minutes on the highest settings.
On average, customers found the battery lasted around 30 minutes, which was disappointing.

First-Hand Impression
Honda 35 cc Straight Shaft Trimmer
Most Powerful
It’s fully equipped with a Honda GX35 4-stroke engine. With the Honda brand name behind it, you can rest assured that this has been designed and built by experts.
It’s also an easy-start engine that is music to the ears of many power tool users. Nothing screams frustration like a power tool you can’t get going.
What We Like
Fuel Efficient Engine
When choosing a gas option, you know it will emit some fumes, which is why it’s super important to choose something that’s fuel-efficient.
With this model, you can enjoy the 4-stroke engine, which is more fuel-efficient than similar 2-stroke engines. This is better for the environment and your bank account since it costs less to run.
Flexible Inner Driveshaft
The shaft design on this tool is lighter and more durable than solid shafts. Due to its flexibility, it has incredible torsional strength, allowing it to absorb shock and reduce vibrations.
In fact, Honda is so confident in its design that the shaft alone comes with a limited lifetime warranty.
Heavy Duty Capability
If you’re going to demand a lot from your string trimmer, this is a fantastic option. It has been designed to handle thick grass and heavy brush with no problems.
This won’t clog up, get bogged down, or give up halfway through a job. It can even tackle these jobs at partial throttle if you’re looking to save fuel.
Easy To Start
The 4-stroke engine is easy to start, saving you time and frustration when you are getting started on your tasks.
What We Don't Like
Poor String Design
Perhaps the manufacturer focused too much time on creating a good engine and not enough time on creating a good string.
Customers tend to complain about the string, which tends to break, knot up, or not feed out correctly during use. This causes a lot of frustration for busy customers.
Expensive Price Point
This is one of the more expensive options on the market. Of course, the price point is justified by the power and technology behind it. But if you’re on a budget, this may not be the right option for you.

EGO Power+ Foldable String Trimmer
Best Quiet String Trimmer
While no string trimmer is completely noiseless (yet), this is a fantastic option if you want something on the quieter side.
Customers love how quiet this product is compared to other options. If you want to do a bit of work in the morning or evening, this shouldn’t annoy the neighbors.
The company’s decibel rating isn’t specified, but one test found it to be around 80 (1). While this isn’t considered silent by any means and is similar to traffic passing by, it won’t be too distracting for others around you.
What We Like
Long Battery Life, Quick Recharge
I think you’ll enjoy the extended battery life of this product. The battery lasts up to one hour, which is generous, but it also charges super quickly. It takes as little as 50 minutes to charge the battery back up so you can get back to work quickly.
Rapid Reload Head
This comes with a handy Rapid Reload Head, which allows you to insert new cutting lines quickly and efficiently. It is much easier than previous models. Simply line up the arrows with the head, insert the line, then twist.
Weather Resistant
If you live somewhere with multiple weather types, you’re probably after something that can withstand that. This tool is weather-resistant, so it will hold up whether there’s rain or shine.
Incredible Brushless Motor
This unit features a brushless motor with high-efficiency results. Not only does this increase the run time, it lowers the vibrations and ensures the overall lifespan of the product is longer.
What We Don't Like
12 Pounds Heavy
This is one of the heavier products I found. Especially since it’s not gas, it’s a bit surprising.
At 12 pounds, this is very heavy and difficult for some customers to manage. If you’ve not got the strongest arm muscles, this may not be the right tool for you.
Not Budget Friendly
If you’re on a budget, the price point might scare you a little. It’s definitely expensive, especially for a battery-powered option.
Many gas models sit around this price, but it’s rare for an electric product. However, it is a powerful tool, so many people think the price is worth it.

Greenworks 15-Inch Corded String Trimmer
Best Affordable String Trimmer
Not everybody has the desire or means to spend hundreds of dollars on a string trimmer. If you’re on a super tight budget, I can recommend this Greenworks string trimmer to you. It’s less than half the average string trimmer cost, but it’s still mighty good quality.
It’s a corded electric option, so while you need to plug it in, you never need to worry about the battery dying while you’re in a great workflow.
What We Like
2-In-1 Edger and Trimmer
2-in-1 trimmers seem to be becoming more and more popular. That’s because they’re super convenient!
But with this product, you’re already getting a bargain, but now you’re getting two tools for a small price? Definitely awesome.
Use the edging wheel to quickly switch from trimming to edging for the most beautiful and tidy garden finish.
Telescoping Shaft for an Extra Seven Inches
With a telescoping shaft, this allows more versatility between short and tall customers. You can extend the shaft an extra seven inches for more comfort for more people.
Cord Lock Prevents Unplugging
Tired of accidentally unplugging your electric power tools? This comes with a cord lock, so when you accidentally pull on the cord, the pressure goes to the cord lock rather than the outlet. So, your power tool shouldn’t come undone when you’re in the middle of a job.
Variable Speed Trigger
With a variable speed trigger, you’re in control. You get to decide how fast or slow this unit works, which allows you to tackle various trimming tasks.
What We Don't Like
Poor String Feed
While the product advertises easy and automatic line feeding, customers have different experiences. The way the line gets fed seems to be a headache point for many customers. Some complain that the string breaks easily, while others said that the line advance is very stubborn.
Too Heavy for Some
While 6.9 pounds is the average for an electric string trimmer, many customers reported that the unit was too heavy. I’m not sure if it’s poorly balanced or perhaps the description understates the weight, but keep this in mind.

Electric vs Gas vs Battery Powered
Before shopping, it’s important to know the difference between the main types of string trimmers. You’ll find both electric and gas string trimmers. Within electric, you’ll also find battery-powered string trimmers which allow the tool to be cordless.
Electric
Pros
- Better for the environment since they don’t emit hazardous fumes.
- No harsh chemicals get into your grass.
- Less cleaning and maintenance for the machine.
- Overall lower running costs than gas.
- More affordable options than gas.
Cons
- They aren’t cordless, which limits maneuverability.
- Typically less powerful than gas options.
- Not ideal for large yards.
Gas
Pros
- Super powerful, good for big jobs and yards.
- Since they run on gas, they’re also cordless.
- Many options available on the market.
Cons
- More expensive than electric and battery-powered.
- Emit fumes, which may upset your grass and plants.
- Louder and may require ear protection.
Battery Powered
Pros
- Completely cordless, which increases maneuverability.
- Nice and lightweight, with many options under 7 pounds.
- More affordable than gas.
- Quiet, which is good for neighbors.
- No toxic fumes.
Cons
- Battery life may not last the entire yard.
- You need to factor in battery recharge time.
- Not as powerful as gas string trimmers.
- Batteries aren’t always super durable, need frequent replacing.
Overall, each string trimmer comes with its advantages and disadvantages. The best way to decide is to consider your yard size and shop accordingly.
How To Choose the Best String Trimmer
Besides the type, what else should you look at before committing to a string trimmer? Check out these important details.
Performance
Look at some key details to decide how well the string trimmer will perform.
First, let’s consider the power. The power of a string trimmer is measured by the engine. You’ll find various engine sizes, normally between 20cc and 30cc. The higher this number, the more powerful the engine.
If you have a big yard and want to zip through jobs quickly, I recommend 25cc or more.
You may also want to consider what height of grass the string trimmer can cut. If you have super tall grass, make sure it can handle it. This isn’t always specified, so check customer reviews to see what others say about tall grass.
If you’re looking at a gas string trimmer, you should definitely consider the gas tank capacity. The higher this is, the longer it will run between refuels. On average, this sits around 12-15 ounces, but there are some options with bigger capacities that are suited to bigger yards.
Versatility
You can get the most out of your string trimmer by choosing one with some versatile features. Whether this allows you to switch up the way you trim (horizontally or vertically) or it comes with attachments, it’s good to check.
Shaft Length
The shaft length refers to the length of the handle. The longer this is, the more suited it is for taller people. The average length is around 45-55 inches, with some longer options available.
Weight
Weight is super important since it will affect how easy or difficult it is to use the string trimmer. The average weight is 10 to 12 pounds for a gas option and 5 to 7 pounds for an electric one. If you’d like something lighter, I definitely recommend choosing electric.
Ergonomic Handle
Take a look at the style of the handle and whether it will be comfortable for you. You may want to choose something that’s slightly curved, which can increase comfort and control. It’s also nice to find something with a grip that can increase control and reduce vibrations.
Budget
If you’re on a budget, I recommend sticking to an electric or battery-powered option, which tends to be between $40 and $100.
Gas string trimmers are much more pricey, costing somewhere between $100 and $200, with many options being even more expensive. Whatever your price point is, there should be something that ticks your boxes.
Safety Tips for Using a String Trimmer
Here are some noteworthy tips to ensure that you’re using your string trimmer safely:
- Dress the part: When using a string trimmer, make sure you wear eye protection, face protection (such as a visor), and adequate clothing. I recommend heavy trousers and a long-sleeved shirt rather than shorts, t-shirts, and sandals. You should also consider ear protection, especially if using a gas trimmer, since these are extra loud.
- Hold correctly: Don’t hold the string trimmer directly over the lawn, as this will cause scalping, scarring, and other lawn damage. Instead, keep the trimmer spool parallel with the ground so the strings are vertical. Then, move in a straight line.
- Tie back long hair: If you have long hair, tie it back in case it gets caught in any element of the power tool.
- Wait for a dry day: Ideally, you should work with dry grass and weeds. Firstly, electricity and water don’t mix. But secondly, it creates a much messier job if the ground is wet.
- Clear the area: Before trimming, make sure the ground is clear. Remove debris such as glass, pebbles, metal, toys, and more, which can easily get caught in the line and fire out at you or someone else nearby.
- Practice a secure grip: When holding the string trimmer, make sure you hold tightly with both hands, holding the power tool on the right side of your body. Keep your left arm straight and your right arm bent slightly.
- Watch out for cables: If using an electric string trimmer or working around other power tools, watch out for cables. You don’t want to cut any cords accidentally.
- Move this way: Aim to move from right to left to help keep the clippings away from you. You should also go top to bottom down the lawn, which is easier for the string trimmer’s engine and kinder to your lawn.
FAQs About String Trimmers
What Size String Trimmer Do I Need?
This depends on your height and preference. If you’re taller, aim for one with a longer shaft.
You should also consider the weight when shopping. Weight tends to span from three to 15 pounds.
In terms of the string size, these come in various thicknesses. The smaller ones (between 0.065-85 inches) are best for light work.
The thicker ones (between 0.085-0.110 inches) suit thick grass and weeds.
Finally, if you have thick underbrush, I recommend anything above 0.110 inches.
Can I Use a Thicker Trimmer Line?
Sometimes. Some tools can handle a range of string thickness, but always check with the manufacturer.
Are Trimmer Heads Universal?
If you need to replace your string trimmer head, there are some excellent universal options on the market.
For example, there’s the Husqvarna 966674401 T25 Tap Trimmer Advance Head, or you could also check out the MAXPOWER PivoTrim Universal Replacement.
What Trimmer Do Landscapers Use?
Regarding trimmers that landscapers use, there is no specific make or model. In my opinion, the best professional trimmer is the Echo SRM Brush Cutter. It has a powerful engine and is comfortable to use for long periods.
Are Curved or Straight Trimmers Better?
Knowing which is better between, curved or straight trimmers, is crucial if you want to reduce back pain. Curved trimmers are more comfortable because they are shaped for better balance.
Are Plastic Blades on a Strimmer Any Good?
Plastic blades on a strimmer are good, provided you don’t hit anything hard. They break on contact, which means you need to replace them.
