Lines that come in this style break less when you hit trees or concrete, and so they have an extended use time. The only shortcoming with the round style line is that it cannot handle large areas and thick weeds well.

#3. Twisted Trimmer Line

A twisted style line is ideal for a rugged commercial use and for clearing lawns and gardens with a lot of thick and heavy weeds. It is the strongest trimmer line for professional trimming purposes because it does not break when you hit trees or concrete.

Trimmer Line Diameter

Apart from the different styles, the trimmer lines also come in various widths. The diameter is an important feature, and this is why trimmer line reviews will always mention it as part of the essential features. It is important to know that the ideal diameter and weight of the line will depend on the type of work.

Light work like clearing back lawns or the front of a residential house will require a line with a small diameter, and so anything between 0.065 and 0.080 inch will be sufficient.

For medium to heavy work such as clearing large lawns with some thick weeds and doing some light commercial trimming will require something with a diameter of between 0.085 and 0.105 inch.

Industrial landscaping, golf courses, big yards like what you find in some hotels and any other places that require a lot of trimming will need a trimming line with a larger diameter of 0.110 inch or more.


There are many styles and types of trimmer line in the market, and so you will need a lot of information to make the right choice. The reviews above and the description of the different styles and diameter will make it easy for you to get the best string trimmer line.
