What Size String Trimmer Line Should I Use?
When it comes to keeping a lawn neat and tidy, the string trimmer shines as a multi-purpose workhorse. Depending on the application, one could use it to mow down hard-to-access areas, trim up grass and weeds that a mower can’t quite reach, clear out thicker brush, and edge out lines for a cleaner looking yard. But, with such a variety of possible applications, as well as possible attachments to meet those demands, it can be difficult to settle on one specific set-up. So, what size string trimmer line should I use? The easy answer is that it depends on how much variable functionality I need from my string trimmer.
String Trimmer Line Thickness
This probably comes as no surprise to anyone, but the general rule with string trimmer line is that the tougher the application, the thicker the line needs to be. A larger diameter will increase the power and durability of the line, which leads to less breakage and wear-out.
String trimmer line comes in a range of thicknesses. For light work, such as trimming grass, 0.065″-0.085″ should be sufficient. For thicker grass and weeds, a line in the 0.085″-0.110″ range will get the job done, and for thicker underbrush, anything thicker than 0.110″ will work.
