The Right Size of Weed Eater String

The first and most important point is to choose the right size of weed eater string.

The reason why it’s important is that performance depends on the strength of the string.

If it’s not powerful, you won’t be able to cut the weed efficiently. 

Weed eater strings are divided into three categories. 

• The first category is the lines that come in sizes 0.065 to 0.084 that are used for light works.  
• The second category of the lines is the one that has the size of 0.085 – 0.105; these are best for medium work or residential use. 
• The last category is the industrial weed eater strings. The size of these strings is above 0.105; they are suitable for heavy work. 

To select the best string size, first of all, determine what type of weed you have in your lawn.

Either it will be thick or thin; if it’s thin, you should go with a size between 0.065 – 0.084. For thick weeds, the best string sizes are between 0.085 – 0.105.
