Chainsaw Sizes
Before you shop for a chainsaw, consider the work you plan to do. The size and type of wood you need to cut and your experience using a chainsaw all factor in when selecting the right model. Bar length is one way to judge a chainsaw’s size and work it can handle. A chainsaw with a longer bar can cut larger-diameter wood in a single pass.
Trimming hedges and small tree branches - The best chainsaws for home use typically have bar lengths that range from 6 inches to 20 inches. These are great for trimming tree branches and cleaning up hedges.
Cutting firewood and large trees - Larger chainsaws with 20-inch or longer bars are good for medium and large trees as well as storm cleanup and cutting firewood.
A longer bar and bigger motor or engine mean increased weight — something to consider if you need to use it for extended periods. Larger saws also create more vibration, take more effort to handle, and increase safety concerns. A small chainsaw, while less powerful, is more manageable, especially if you don’t have much experience.
Engine displacement (gasoline-powered models), voltage (cordless models), amperage (corded models) and horsepower all relate to power and capability. The higher the number, the more powerful the chainsaw.
Types of Chainsaws
Electric Chainsaws
Battery powered chainsaws are good for small jobs like trimming, pruning and jobs that require less power. Battery chainsaws are quieter and easier to start than a gas chainsaw and require less maintenance. There are both corded and cordless varieties.
Cordless Chainsaws – A cordless chainsaw offers good mobility and less vibration. The electric motor is quieter and runs without producing emissions that a gas engine would. Some of the best battery chainsaws have brushless motors and higher-voltage batteries for long-lasting power. Battery-operated chainsaws can handle large tasks like cutting logs and tree trunks in addition to trimming smaller branches.
Corded Chainsaws – A corded chainsaw is lighter and doesn’t need to be charged. It does require a suitable extension cord that reaches the work area, so you may need to factor this into the cost. Your work area is limited by cord length, and you must keep the cord out of the way as you work. Follow the device manufacturer’s instructions for selecting a compatible extension cord.
Gas Chainsaws
Gas chainsaws combine power and mobility. They range from light-duty models to professional-grade saws that can cut down large trees. A gasoline-powered chainsaw cranks with a pull-start and has a two-cycle engine that operates on a mixture of oil and gasoline. You can mix the fuel yourself or purchase pre-blended fuel.
To maximize your outdoor tool kit, look for equipment that uses the same battery and charger.
Pole Saw Chainsaws
A pole saw is a small chainsaw mounted on an extension pole. It increases your reach for pruning and removing small tree limbs. They're available in gasoline-powered, cordless and corded models. The handle of some models can be lengthened by attaching a solid extender piece, while other models have telescopic poles for maximum versatility. Choose a pole saw that can convert to standard chainsaws for the best of both worlds. Already have a string trimmer in your arsenal? Opt for a pole saw attachments instead.
Chainsaw Features
While size and power help determine the best electric chainsaw or gas chainsaw for your work, there are other features that improve comfort, safety and efficiency.
- Anti-Vibration - This makes a chainsaw more comfortable to use and reduces fatigue. These systems are especially helpful if you have a lot of cutting to do.
- Spring-Assist Start – This reduces the pulling force needed to start a gas chainsaw.
- Automatic Oiler – An automatic oiler lubricates the chain as you cut. Proper chain lubrication is necessary for safe and efficient cutting.
- Chain Brake Stop – This stops the chain when the saw encounters an abrupt movement or impact. On equipped models, you can also manually activate the chain brake.
- Low-Kickback Bars – These help reduce the risk of the saw being unexpectedly forced back and up.
- Toolless Chain Adjustment – Allows you to change the cutting chain tension quickly and easily.
- Air-Cleaning – This feature extends air filter life by removing large pieces of debris before they reach the filter.
- Carrying Case – A carrying case protects the saw and makes transporting easier and safer.
You may notice chain pitch and gauge specifications on your chainsaw. Pitch is the spacing of the rivets on the chain. It must correspond with the spacing of the teeth on the sprocket at the end of the bar. Gauge is the thickness of the chain. Make note of these measurements when purchasing a spare chainsaw chain, new chainsaw bar or bar and chain set.
Chainsaw Safety Equipment
Personal safety equipment is necessary for use of any power equipment. Standard safety gear for operating a chain saw include:
- Eye protection with side shields
- Hearing protection, such as earmuffs and earplugs
- Work Boots or shoes with steel toes and nonskid soles
- Leg protection, such as chaps or cut-resistant pants
- Gloves with enhanced gripping surfaces and cut resistance
- Chainsaw helmets that include face protection, neck guards and hearing protection
For more information on using a chainsaw safely, see our article on Chainsaw Safety. Our gas chainsaw and battery-operated chainsaw maintenance guides will tell you how to sharpen a chainsaw chain and keep your saw operating properly.
Keep a scrench tool (all-in-one tool), a chainsaw sharpening kit and chainsaw files on hand to make sure your chain is always ready to cut.
