Choosing a cordless string trimmer shouldn’t be complicated. There are dozens of models on the market, ranging from lightweight 20V starters to heavy-duty 60V workhorses. The right one depends almost entirely on how much lawn you’re dealing with.
What to Look for in a Cordless String Trimmer
Four specs determine whether a trimmer will keep up with your yard or leave you frustrated mid-job.
Voltage: Higher voltage means more cutting power. A 20V trimmer handles light residential use well. Step up to 40V or 60V for thicker grass, overgrown edges, or larger properties.
Cut width: Most residential models cut between 12 and 15 inches per pass. A wider cut width means fewer passes and less time spent trimming.
Battery runtime: Expect 20 to 45 minutes on a full charge depending on the model and terrain. Brushless motors extend runtime by up to 50% compared to brushed motors.
Weight: Cordless trimmers range from 5 to 12 pounds. Lighter models are easier to maneuver around flower beds and tight corners. Heavier models typically pack more power.
Small Yards (Under 3,000 sq ft) — What You Need
A small yard calls for a light, nimble trimmer. You don’t need maximum voltage or a massive battery.
A 20V to 40V model with a 12-inch cut width is more than enough for trimming edges around a patio, garden bed, or sidewalk. Runtime of 20 to 25 minutes is sufficient for most small properties. You’ll be done before the battery runs low.
Look for a 2-in-1 design that converts from trimmer to edger with a simple rotation. These models eliminate the need to buy a separate edger and keep your garage less cluttered. Weight matters here too. A trimmer under 6 pounds reduces fatigue on tighter jobs.
Medium Yards (3,000 to 8,000 sq ft) — Step Up the Power
Medium-sized yards demand more from your equipment. Longer runtime and a stronger motor become real priorities.
A 40V brushless trimmer is the sweet spot. Brushless motors run cooler, last longer, and extract more power from each charge compared to brushed alternatives. Expect 35 to 45 minutes of runtime from a 4.0Ah battery at this voltage.
Battery platform compatibility is worth thinking about at this stage. If you already own cordless tools from a specific brand, choosing a trimmer that shares the same battery platform saves money. One battery works across your drill, saw, and trimmer.
A 14 to 15 inch cut width at this yard size will noticeably cut your trimming time compared to a narrow 12-inch model.
Large Yards (8,000 sq ft and Up) — Go Heavy-Duty
Anything above 8,000 square feet is where underpowered trimmers start to show their limits. You need sustained cutting power and long runtime.
A 60V model with a brushless motor is the right call. These trimmers handle tall grass, thick weed growth, and uneven terrain without bogging down mid-pass. Cut widths of 15 to 17 inches are standard at this power level.
If your yard includes areas with heavy overgrowth, look for a model with a variable speed trigger. Running at reduced speed on lighter sections preserves battery life for the demanding stretches. Some premium models also support dual batteries for continuous use without stopping to recharge.

FAQ
What voltage is best for a residential lawn?
For most Canadian homeowners, a 40V cordless string trimmer hits the right balance of power and runtime. A 20V model works for small, low-maintenance yards. If your lawn exceeds 8,000 square feet or includes dense growth, a 60V trimmer is worth the investment.
Can I use the same battery for my trimmer and other cordless tools?
Yes, if you buy within the same brand’s battery platform. Most major brands, including DeWalt, Milwaukee, EGO, and Ryobi, use shared battery systems across their cordless tool lineup. Confirm compatibility before purchasing by checking the voltage and connector type.
How should I store a cordless trimmer through a Canadian winter?
Store the trimmer indoors in a dry, temperature-controlled space. Remove the battery and store it separately at room temperature. Lithium-ion batteries degrade faster when stored in freezing conditions or left fully discharged. A charge level of around 50% is ideal for long-term storage.
What is the difference between a string trimmer and a lawn edger?
A string trimmer cuts grass along fences, garden beds, and areas a mower can’t reach. A lawn edger creates a clean, defined boundary between your lawn and a hard surface like a sidewalk or driveway. Many cordless models now function as both, converting between modes with a simple adjustment.
Conclusion
The right trimmer comes down to your yard size, the growth you’re dealing with, and the battery platform you already own. A 20V or 40V model handles most residential properties in Canada without issues. Step up to 60V if you’re working with a larger lot or tougher terrain.
Whatever your situation, matching the tool to the job saves you time and battery life every single session. Start with your yard size, then choose your voltage. The rest follows from there.
