How to Choose a Chainsaw: Bar Length, Gas vs Electric
For most homeowners cutting storm debris, firewood from smaller logs, and limbing: a 16-inch 40V-56V battery chainsaw (EGO CS1804, Greenworks 40V) covers everything. For regular firewood processing from larger logs or occasional tree felling: a 16-20" gas saw (Husqvarna 130, ECHO CS-590). For professional or farm use: 20"+ gas (Husqvarna 455, Stihl MS 271).

Who This Guide Is For
This guide is for you if:
- You're equipping an outdoor space and want to know what's actually worth buying
- You want honest trade-off analysis before spending $200+ on outdoor equipment
- You're comparing options and need guidance, not just sales copy

- You're a landscaping professional — this guide is for homeowners
Start Here: Match the Saw to the Job
The most common chainsaw mistake is buying too much saw — a 20-inch gas saw for occasional storm cleanup that becomes 50 lbs of maintained anxiety in the garage. The second most common mistake is buying too little — a battery pruning saw for firewood processing that runs out of charge halfway through a cord of oak.
Before you read any further, answer these questions:
- What's the largest diameter wood you'll regularly cut?
- How often will you use the saw? (Twice a year vs twice a month changes everything)
- Do you have somewhere to store gas equipment and are you willing to mix fuel and do seasonal maintenance?
- Will you be cutting far from power outlets or a charging station?

How We Chose
We researched dozens of options, analyzed thousands of verified reviews on Amazon and Reddit, and cross-referenced expert recommendations from Ryan Knorr Lawn Care, Wirecutter outdoor testing, and verified homeowner reviews. We prioritized products with active 2025–2026 availability, documented warranty support, and real-world performance data — not just spec sheet claims. Every product we feature must be available to buy today and offer a clear advantage over alternatives at its price point.
Bar Length Guide: The Selector Nobody Explains Clearly
The bar length determines the maximum diameter log you can cut in a single pass. The rule: your bar should be 2 inches longer than the widest cut you'll regularly make. Cutting a 12-inch log with a 12-inch bar is technically possible but requires rocking the saw — add 2 inches of margin for safe, efficient cuts.
| Bar Length | Max Practical Diameter | Best For |
|---|---|---|
| 10–12" | 8–10" logs | Pruning fruit trees, light limbing, precision detail work |
| 14–16" | 12–14" logs | Storm cleanup, firewood from smaller trees, general homeowner use |
| 18–20" | 16–18" logs | Felling medium trees, processing firewood from larger logs, small farm use |
| 20–24" | 18–22" logs | Felling mature hardwoods, professional or farm use, land clearing |
| 24"+ | 20"+ logs | Professional logging, timber felling — not a homeowner tool |
Important: A longer bar on an underpowered engine is worse than a shorter bar on an appropriate engine. The saw must have enough power to pull the chain through the full bar length under load. Matching engine cc (gas) or voltage (battery) to bar length is as important as the bar length itself.
Gas vs Battery vs Electric: The Honest Breakdown by Use Case
Battery Chainsaws: When to Choose Them
Modern 40V-80V battery chainsaws have crossed the performance threshold for all homeowner-scale work. The EGO 56V and Greenworks 80V saws are legitimately comparable to 35-40cc gas saws for the tasks most homeowners encounter. For anything up to 14" diameter and sessions under 2 hours, battery is the practical choice.
Choose battery when:
- You use the saw less than once a week and don't want to deal with stale fuel issues
- You already own same-brand batteries (platform investment pays off)
- You work near structures where fuel storage is impractical
- Noise is a concern (battery saws run significantly quieter — 95-98 dB vs 100-105 dB for gas)
- You mainly do limbing and storm cleanup in suburban yards
Battery limitations to understand:
- Runtime: 45-90 minutes per charge depending on work load. Multiple batteries needed for extended sessions.
- Cold weather performance: lithium batteries lose capacity below 40°F. Keep batteries warm before winter use.
- Battery degradation: replace packs every 3-5 years ($40-$80 per battery)
- Maximum power ceiling: the best 56-80V battery saws match gas saws up to about 45cc — above that, gas still wins
Gas Chainsaws: When They're Still the Right Choice
Gas chainsaws have no runtime limits, no temperature restrictions, and at 50cc+ they outperform any current battery equivalent for sustained heavy cutting. For professional use, farm and acreage work, or regular felling of trees over 12" diameter — gas is still the tool.
Choose gas when:
- You process multiple cords of firewood per year
- You regularly fell trees over 12" diameter
- You work far from power — off-grid, remote property, logging
- You need sustained cutting power for hours at a time
- You're in a professional or semi-professional context
Gas chainsaw maintenance reality: Gas saws need fuel mixed correctly (40:1 or 50:1 — check your manual), carburetor adjustment seasonally, air filter cleaning, spark plug replacement annually, chain sharpening every 5-8 hours of cutting, and proper winterization if stored for months. This isn't difficult, but it's time investment that battery saws eliminate.
Corded Electric: The Forgotten Option
Corded electric chainsaws (Greenworks 14" corded, WEN models at $50-$100) are underrated for very light, very occasional use close to the house. No battery management, consistent power, very quiet. The 100-foot extension cord limit makes them useless for clearing the back 40 but perfectly adequate for pruning the apple tree and cutting up fallen branches near the house. Not discussed further because battery has effectively replaced them for most buyers.
Chain Types: The Spec That Changes How the Saw Feels
Full Chisel
Square-cornered teeth that cut aggressively and fast. Maximum cutting speed in clean, hard wood. Dulls faster when hitting dirt, sand, or embedded debris. Best for professional use in clean logs — the chain used by loggers and experienced operators. Not forgiving of dirty or frozen wood.

The Husqvarna 130 is the entry point into Husqvarna's professional DNA without the professional price. The X-Torq engine exceeds EPA emissions requirements while delivering more torque than comparable budget gas saws — you feel the difference when you're 4 inches into a 12-inch hardwood log and the saw doesn't bog down. The Smart Start system reduces pull-cord resistance significantly. The auto-return stop switch combines the on/off and choke functions — one of the few usability improvements that actually reduces user error. The 2-year consumer warranty covers the type of use most homeowners give it.

The Husqvarna 455 Rancher is what serious homesteaders, hobby loggers, and anyone processing their own firewood long-term reaches for. The 55cc X-Torq engine produces 3.5 HP with excellent torque through thick hardwood. The 20-inch bar handles trees up to 18 inches in diameter cleanly. The LowVib anti-vibration system reduces hand and arm fatigue during long sessions — if you're processing cords of wood, this matters more than raw power. X-Guard bar oil pump reduces consumption by 75% without reducing lubrication. The Rancher is a working tool, not a homeowner toy — built to the same tolerances as professional Husqvarna saws at a consumer price point.

Read Full Analysis
The Stihl MS 162 is the compact specialist — at 7.3 lbs with a 12-inch bar, it handles pruning, orchard work, and precision limbing better than any larger saw. The Quickstop chain brake engages in milliseconds. Stihl's 2-MIX engine technology runs on a 50:1 fuel mix (most gas saws require 40:1 — read the manual). The MS 162 doesn't pretend to fell trees; it's purpose-built for work above your waist and in tight spaces. For homeowners who primarily prune fruit trees, clear brush, and occasionally clean up small storm limbs — this is the right-sized tool.
