Best Overall

Oregon 22-855 Magnum Gatorline

Pros
  • Thicker string for heavier vegetation
  • Durable
Cons
  • May not work as well with less powerful trimmers

If you’re dealing with ultra-rugged brush and weeds, this heavy-duty string could be a great fit. Its square shape and thick, 0.155-inch size allows it to easily chop through thick vegetation without affecting your machine’s efficiency.

A strong inner core also increases its durability, reducing the chances of it snapping or fraying when it comes in contact with fences or rocks.

This durability also allows you to work longer, and spend less time refilling your spool. It’s a bit pricier than most options though, so make sure you really need a string this heavy-duty.

A Anleolife 5-Pound Commercial Square String Trimmer Line

Pros
  • Flexible string
  • Near-universal compatibility
Cons
  • Heavier spool

This string comes in at a lengthy 1280 feet, making it great for those who do a substantial amount of weed whacking, or plan to in the near future and want to stock up.

Its square shape provides the sharp edges necessary to slice through grass, and the 0.095-inch size allows it to be relatively flexible, and should reduce the chances of it snapping or cracking during use.

It’s also compatible with nearly all trimmers, gas and electric, so you shouldn’t have an issue fitting it in your machine. A small cutter is included to make it easy to quickly snip your string to length whenever you need to.

Pros
  • Affordable price
  • Durable design
Cons
  • Not durable enough for heavy-duty use

This 0.08-inch Oregon string is designed for lighter-duty use, like low grass and weeds, and is compatible with a range of trimmer brands like Stihl, DeWalt, Ryobi, and Greenworks.

At 413 feet in length, this should last you quite a while, and for about $15, is relatively cheap compared to most other options. Even though it’s not suitable for heavy-duty use, this string is still nice and durable, as the round shape should reduce the chances of breakage during operation, and an outer shell helps to resist any welding with the line itself.

Best for General Use

Stihl Premium Round Trimmer Line

Pros
  • Works for most vegetations
  • Bright colors make visibility easier
Cons
  • Some users report broken lines when edging

If you’re looking for a reliable, quality string for general use around the yard, this round 0.095 string should be a great fit. Stihl has been making quality tools—and accessories like this string—for nearly 100 years, and though it isn’t going to be ideal for rugged applications like removing thick weeds, it’s still nice and durable, and should last a while.

Its bright orange color also makes it easy to see exactly how far out it’s going to reach, which comes in handy for those precision tasks.

Best Twisted Option

Oregon 20-020 Magnum Gatorline Supertwist Trimmer Line

Pros
  • Quieter sound when in use
  • Twisted design leads to sharper cuts
Cons
  • Lower line visibility when in use

The twisted design of this Oregon string combines the durability of a rounded model with the aggressive cutting power that comes from a textured shape. This design also creates less drag when whipping through the air, which tends to result in a quieter operation than other string shapes.

We’re always looking for products that reduce the chances of potential hearing damage over time, so this feature is definitely appreciated.

This string is compatible with heavy-duty eaters like Husqvarna, Stihl, Troy-Bilt, and Echo models, and the durable inner core means you’ll spend less time bending over to change or replace your string.

Best Star-Shaped Option

Best Star-Shaped Option

Cyclone Desert Extrusion Commercial Trimmer Line (4-Pack)

Pros
  • Affordable price
  • Star shape is effective for cleaner cuts
Cons
  • Not capable of heavy-duty cutting

The star-shaped design of this model features six blades for maximum cutting power, and should be compatible with most trimmers that use 0.065 size string.

We’re big fans of this low-cost option too — for just $14 you’re getting 300 feet of string — and its compact donut packaging is convenient for those who don’t have the space to store larger spools.

The thin size makes this string impractical for heavy-duty use, however, but it should easily slice through most typical residential grass and leave you with clean, precise results.

A Anleolife Sawtooth Dual-Core Serrated Trimmer Line

Pros
  • Serrated design saws through thicker vegetation
  • Comes with cutting tool
Cons
  • For walk behind use specifically

The serrated design of this string features rigid teeth for sawing through extremely thick and dense vegetation. It’s designed specifically for walk-behind trimmers, though, not your typical handheld models, so keep that in mind.

It wouldn’t be a practical choice for use on regular lawn grass, but if you have an area of overgrowth that you need to quickly and easily take down, this string is probably going to be your best bet. Plus, it comes with a handy cutting tool, making it simple to snip off the end when loading it up.
