how to choose the right string trimmer line?
When it comes to keeping your lawn neat and well-maintained, a string trimmer—also known as a "weed eater" or "brush cutter"—is an essential tool for both homeowners and professionals. Whether you're tackling hard-to-reach areas, trimming grass that a lawnmower can't reach, or clearing thick brush, the right string trimmer line can make all the difference. BISON is here to guide you through the process of selecting the perfect line that matches your trimmer's specifications and your specific needs.
The Role of a String Trimmer
String trimmers work by spinning a monofilament line at high speed, which generates enough centrifugal force to keep the line straight and sharp enough to cut through grass and weeds. This makes them ideal for trimming around trees, walls, fences, and other obstacles where a traditional lawnmower might struggle.
You can also use the trimmer vertically as an edger along driveways and sidewalks. Many gas-powered models allow you to switch between different types of cutting heads, so it’s always a good idea to check your owner’s manual for compatibility and recommended line types. From thin spools to thick pre-cut lines, square or serrated options are available, ensuring that the motor’s power is used efficiently and that your cuts are clean and effective.
Understanding String Trimmer Line Dimensions
Choosing the right string trimmer line starts with understanding its diameter, which is typically measured in inches or millimeters. The thickness of the line directly affects how well it can handle different types of vegetation and how long it will last before breaking.
Thin lines (0.065–0.070 inches) are lightweight and ideal for trimming short grass and light weeds. They offer precision but may break more easily when encountering tougher obstacles.
Middle-range lines (0.085–0.110 inches) strike a balance between flexibility and strength, making them suitable for most residential tasks. They’re durable enough to handle stubborn weeds without overloading the motor.
Thicker lines (0.110 inches and above) are built for heavy-duty use, such as cutting through dense brush or tall grass. However, they require more powerful trimmers and can be harder to maneuver for delicate jobs.
Lines can range from 10 to 25 feet in length, but the optimal length depends on your trimmer model. Always check the guard for markings that indicate the maximum length your unit can handle.
Factors to Consider When Choosing a String Trimmer Line
Several factors should influence your choice of string trimmer line. Here are some key considerations:
Type of Vegetation and Area Size
The type of plants you need to trim determines the line size and strength required. For example:
Light Tasks: Thin lines (0.065–0.070 inches) are perfect for regular lawn maintenance and trimming light weeds.
Medium Tasks: Medium-thickness lines (0.080–0.095 inches) offer more durability for tougher grass and weeds without overworking the trimmer.
Heavy Tasks: Thick lines (0.105 inches and above) are necessary for dense vegetation, shrubs, and woody plants.
For larger lawns, you’ll likely need a thicker line to handle the workload effectively.
Line Shape and Material
Not only does the thickness matter, but the shape of the line also impacts performance. Common shapes include round, twisted, square, serrated, and star-shaped. While round lines are standard, they tend to tear grass rather than cut it cleanly. Twisted lines have more cutting edges, making them better for thick, overgrown areas. Square or star-shaped lines provide a cleaner cut, while serrated lines act like small saws for heavy-duty trimming.
Material choices vary too. Nylon is the most common, but reinforced composite nylon, internally strengthened lines, and even aluminum-enhanced options are available for more demanding jobs. If you're primarily trimming light grass, a basic nylon line will suffice.
Personal Preferences and Professional Experience
Many professional landscapers have their preferred line type based on experience. They often go for medium to heavy lines (0.080–0.105 inches), as these are more durable and efficient for large-scale projects. Professionals also tend to favor twisted or serrated lines for better cutting performance, rather than round or square ones.
Conclusion
In this article, we’ve explored the key factors that influence the choice of a string trimmer line. The right line can greatly enhance your trimming experience, whether you're working on a small backyard or a large commercial property.
For most homeowners, a standard round nylon line will work well for everyday tasks. But with the information provided, you should now be better equipped to choose the best line for your specific needs. If you need help finding the right product, feel free to contact us at BISON.

FAQs
How to Replace a String Trimmer Line?
Here’s a simple step-by-step guide:
Cut the new line to about 10 feet and remove the cutting head if possible.
Unscrew the lug knob and take off the inner wheel and spring.
Wrap the new line around the spool, making sure it’s tight and secure.
Reassemble the parts and reattach the cutting head.
Why Do My String Trimmer Lines Keep Melting?
Trimmer lines can melt together due to excessive heat buildup, especially when trimming near concrete, asphalt, or fences. To prevent this, take regular breaks and feed the line slowly. Avoid continuous use in hot conditions.
How Can I Get the Most Out of My Trimmer Line?
To maximize the life and performance of your string trimmer line, follow these tips:
Regularly inspect the line for wear and replace it before it becomes too damaged. Clean the spool to avoid debris buildup.
Use fast, sweeping motions with thinner lines, and slower, steady movements with thicker lines for better results.
Invest in high-quality lines, even if they cost more upfront—they’ll last longer and perform better.
Always wear protective gear like goggles, gloves, and long pants, and make sure no one is nearby during operation for safety.
