So, first thing’s first…

What should you be thinking about when you need to replace your trimmer line?

What To Look For When Buying Trimmer Line

While the build quality of your weed eater is crucial, it’s the trimmer line that actually does the hard work.

Getting this element right is critical. The sort of line you choose will affect how your machine cuts, the types of material it can slice through and how long your line will last.

That being said, you’ll generally be very limited as to what line you can use. This is dictated by the string trimmer or brush cutter you’ll be using.

Strimmer Line Guide

Light - Medium Cutting

  • You’ll want spooled line. Go for 0.8-inch round line or 0.065-inch 5-sided line

Medium - Heavy Cutting

  • If you opt for pre-cut line, 0.095-inch square line or 0.099-inch serrated line. With spooled string, 0.095-inch 5-sided line or .105-inch square line both work well

Very Heavy Cutting

With extremely heavy cutting duties, go for 0.130-inch square line or 0.168-inch serrated. 0.130-inch twisted and 0.170-inch square line are a good fit if you’re using spooled line

Installation of Trimmer Line: Pre-Cut or Spooled?

In the guidelines above, you’ll notice your 2 main choices with trimmer line: pre-cut and spooled.

Before thinking about this, check the manual of your trimmer and see what type of line it suggests.

Compatibility is all about the trimmer head. If you have replaced this part of your cutter then take this into account.

If you have a fixed head trimmer, you’ll want pre-cut line.

Bump feed or twist feed systems mean you’ll need to hunt out some spooled trimmer line.

  • Pre-Cut Trimmer Line: Rather than one long length, pre-cut trimmer line comes in individual lengths. This makes changing your line quick and easy. On the flipside, you’ll need to change the line frequently if you gauge the durability incorrectly
  • Spooled Trimmer Line: The majority of trimmers use a spool of line which is wrapped around the head. Check to see how simple reloading is. This varies from trimmer to trimmer

As with most aspects of choosing trimmer line, you don’t have much choice here. The type of appliance you have makes the decision for you when it comes to pre-cut or spooled line.

Diameter of Trimmer Line

This is straightforward. The thicker the diameter, the heavier application it will serve.

With a larger diameter, you’ll enjoy increased cutting power. The line will also last longer when dealing with thick weeds and grass.

Again, consult your user manual. Most trimmers will only accommodate certain diameters of line.

Shape of Trimmer Line

The different shapes used for trimmer line influences the manner and efficiency of cutting.

You’ll come across round, twisted and squared line. There’s line with 5 or 6 points.

Broadly, you can think of line falling into 2 main categories:

  • Round or Twisted
  • Edged (square, 5 point, 6 point…)

The most common variety is round line. Due to the lack of cutting edges, round line can rip and tear grass rather than properly cutting.

A step up is twisted line. These sharp edges slice through even the thickest of weeds with little resistance.

Serrated line gives enhanced cutting power. In general, more edges translate to more power. Be careful when using this type of line. It can induce a grabbing action where the trimmer is pulled down toward the vegetation. Go slowly and get the feel for it to avoid accidents.


The majority of trimmer line is made from nylon.

There are variations on this when the goal is increased performance or durability.

Composite materials are sometimes added to the nylon for extra strength. Non-nylon polymers are also used for this purpose. Aluminum is another material thrown in for enhanced longevity.

The line can be reinforced to limit breakage.

Take a look at the material of the trimmer line you have in mind. Think about how the material will work for the cutting you have in mind.


Now you know what you need to focus on, it’s time for our look at the top 5 trimmer line so you can make the best choice.
