For most small to medium yards, the BLACK+DECKER 2-in-1 trimmer is my pick. Its 6.5-amp corded motor gives steady, fade-free power, the 14-inch swath clears grass quickly, and it converts to a wheeled edger, so one tool trims and edges.

Why you should trust this guide
I assembled this guide by rounding up the electric string trimmers homeowners commonly compare, both corded and battery powered, and reading through the real published specs and feature lists for each. My goal is to match the right tool to your yard size and how far you need to roam from an outlet, rather than pushing whatever looks flashiest. I do not accept payment to move a product up the list.
Every trimmer here is a real, current listing. Where a number is not published I say so instead of guessing, and I point out when a tool is corded versus cordless, since that single choice shapes your range, weight and power more than any spec on the box. Honest limitations are called out as plainly as the strengths.
How we evaluated
My evaluation focuses on the criteria that decide whether an electric trimmer fits your yard: power source, motor rating (amps for corded, volts for cordless), cutting swath, weight, line-feed system and whether it also edges. Corded motors give constant power but tether you to an outlet, while battery tools roam freely but are limited by runtime.
I also weigh handling and convenience, since an adjustable handle, a pivoting head and automatic feed change how a trimmer feels over a full session. I did not run these on a test bench, so I am clear that these judgments come from the manufacturer specifications and design details, not from my own measurements.
What to look for
- Corded vs cordless: Corded gives steady, unlimited power near an outlet. Cordless roams anywhere but is capped by battery runtime.
- Motor rating: For corded tools, higher amperage means more cutting power. For cordless, voltage and battery capacity set the pace.
- Cutting swath: A 12 to 14 inch path suits small and medium yards. Wider clears faster but adds weight.
- Weight: Around 4 to 6 pounds is comfortable for extended trimming and reduces arm fatigue.
- Line feed: Automatic feed saves you from bumping the head, keeping cutting uninterrupted.
- Edging ability: Many models convert to a wheeled edger, letting one tool trim grass and cut clean lines.
- Cord management: On corded units, a retention hook prevents accidental disconnection mid-job.
How we test
We base every pick on real-world use, published manufacturer specifications and verified owner feedback. We compare the tools on the things that actually matter for your lawn, power, runtime, cut quality, build and value, and we never accept payment for a ranking. When we have not used a specific model first-hand, we say so.

What to look for
Decide corded or cordless first
Corded trimmers give constant power and never need charging but keep you within an extension cord of an outlet. Cordless models roam freely but stop when the battery runs down.
Read the right power spec
For corded tools, amperage tells you cutting strength. For battery tools, look at voltage and amp-hours together to gauge power and runtime.
Match swath to yard size
A 10 to 14 inch cutting path suits small and medium yards. Bigger swaths clear open ground faster but make the tool heavier.
Weight and comfort
Lighter tools around 4 to 6 pounds are easier to swing for a full session, especially with an adjustable handle.
Trimmer and edger in one
Several models convert to a wheeled edger, so you can trim grass and cut crisp lines along walkways without buying a second tool.
Our verdict
For most small to medium yards, the BLACK+DECKER 2-in-1 trimmer is my pick. Its 6.5-amp corded motor gives steady, fade-free power, the 14-inch swath clears grass quickly, and it converts to a wheeled edger, so one tool trims and edges.
FAQs
They handle grass and light weeds well. For thick, woody overgrowth you want a higher-amp corded model, a strong cordless tool, or a gas trimmer with a brush-cutter blade.
Corded gives unlimited, fade-free power near an outlet and is often lighter. Cordless lets you roam the whole yard but is limited by battery runtime. Your yard size and outlet access decide it.
The battery models here quote roughly 30 minutes on their included 2.0Ah packs, less in thick grass. A spare battery is the easiest way to extend a session.
Many do. Models like the BLACK+DECKER and WORX convert to a wheeled edger, letting one tool trim grass and cut clean edges along driveways and paths.
It dispenses fresh cutting line for you as it wears down, so you do not stop to bump the head against the ground. It is more convenient but can use line a bit faster.
