Cutting the grass is the first step in maintaining a well-manicured yard. Once you’ve done that, you may need a tool for trimming around the edges.

“The lawn mower is your ‘big picture’ tool, but the string trimmer is all about those important details,” says Bryan Clayton, pro landscaper and CEO of GreenPal. “They’re the unsung heroes of a polished lawn.”

But just as there are myriad options in lawn mowers, there’s a wide range of string trimmers to choose from. How to select the right one? “Trusted brands and models with expert recommendations are usually a safe bet,” says Zahid Adnan, gardener, horticulturist and the founder of The Plant Bible. “Brands like Stihl, Husqvarna, Black and Decker and Greenworks are known for producing reliable string trimmers across various price ranges.”

Here, landscaping and lawn care experts reveal what considerations to make as you select the perfect trimmer for your needs. Then they offer their top picks in several categories.

What To Look For


There are some important criteria to consider before buying a string trimmer. Here are the main factors lawn experts look for when buying their own trimmers:

Power Source

String trimmers can be divided into three categories: corded electric, battery-operated or gas-powered. “Corded trimmers are generally lightweight and eco-friendly, but you’re limited by the cord’s length,” Adnan says. Battery-operated trimmers offer you mobility, but the batteries need to be charged after a few hours of use (and sometimes even more frequently).

“In my experience, gas is usually the most powerful but is heavier and requires more maintenance,” Clayton says. And gas is also beginning to go out of favor as environmental concerns change peoples’ perspectives about carbon emissions.

Engine Power

How powerful is the engine? The manufacturer will indicate the engine’s strength in terms of cubic centimeters (“CCs”) or volts. If you have an expansive yard with rugged terrain, you may need more power for trimming and edging.


Depending on the brand and model, a string trimmer might sell for under $100 or over $500.

Cutting Width

“The cutting width determines how much area the trimmer can cover in one pass,” Adnan says. “A wider cutting width is more efficient for larger yards, while a narrower one is suitable for precision work.”

Clayton zeroes in on how that idea affects your trimmer selection: “You might think bigger is better, but not always,” he says. “Smaller yards benefit from a narrower cutting width for precision.”

Weight and Ergonomics

String trimmers can weigh anywhere from 5 pounds to over 20 pounds. Obviously, the lighter the trimmer, the easier it is to carry around. But the design of the frame also impacts the comfort level.

“Most people don’t know this, but holding a poorly designed trimmer for an extended period is no joke on your back and arms,” says Clayton. Features like ergonomic handles can make this tool more comfortable to operate.

Special Features

String trimmers might have special components like a push-button start, a shoulder strap or harness, a variable speed trigger or a brushless motor.
