Frequently Asked Questions


Q: What Size Trimmer Line Should I Use? 

A: Check your trimmer's user manual for the right size of line that's right for your trimmer. Line comes in light, medium and heavy diameters. Light line is great for trimming ordinary grass and small weeds around the home. Pick up a medium line to groom bigger lawns and cut thicker weeds. For large landscaping projects with thick grass and hefty shrubs, a heavy line is highly recommended.


Q: How Long Should Weed Wacker String Be? 

A: The length of your trimmer line depends on the size of your weed wacker — check the instruction manual. Automatic-feed trimmers will dispense the correct length of string as you work. Weed wacker string comes in different spool lengths. Choose one that’ll last the whole season or buy a multi-pack to ensure you don’t run out.


If you're not sure how to string a weed wacker, check the instruction manual for guidance since each model is different. Learn more tips and tricks by reading String Trimmer Maintenance.


Q: How do I choose a trimmer line? 

A: Trimmer line also comes in many shapes and materials. Round line will get you through basic trimming tasks around the home. Select square, star or hexagonal line with corners if you prefer to slice through grass blades for a refined trim. Titanium's the best trimmer line material, while twisted line has the best durability.
