If you’re looking for the best 18 inch chainsaw, you’ll likely find that you have tons of options to choose from.

Depending on your needs and preferences, you can buy saws with bar and chain lengths as low as 10 inches or as much as 59 inches in length.

However, most homeowners and professionals will choose saws in the middle of that range - making the 18 inch saw a great option for newbies and experts alike.

There are a few factors you'll want to consider when you shop for the right chainsaw.

Here's what you need to know.

Tips For Selecting The Best 18 Inch Chainsaw

Keep these things in mind when you start shopping for your next chainsaw, regardless of whether you’re the casual user cutting firewood on the weekends or a professional logger working in the woods every day.

Electric vs Gas - Best 18 Inch Chainsaw

You can buy 18-inch chainsaws that are powered by either gas or electricity.

Those that are powered by gas have two-stroke engines that are meant to provide constant power to your saw.

Although these require more maintenance, they offer a significantly higher level of power  - making them ideal for cutting down trees.

Electric saws are just fine if you’re only planning on bucking up small amounts of firewood.

They are much quieter than gas saws and while they aren’t as powerful, they are lighter because they tend to be battery powered.

They also have few maintenance needs.

Potential Use

Before jumping into a purchase, think carefully about how you plan to use your saw.

You’ll want to consider what users say in their reviews - is this saw meant for cutting up firewood?

Knocking down trees?

What are any issues that users have encountered?


Knowing how to maintain a chainsaw is another integral component of owning one.

Pay attention to the maintenance requirements for the saw you select - again, gas-powered saws require more maintenance but they offer much more power.

Even with electric saws, there will be some maintenance required - and unfortunately, it is very difficult to service most engines of electric saws yourself.

You’ll need a repair shop to do it for you.
