What Size Chainsaw Do I Need?


As a forester or someone who often needs to cut down trees, you’re probably interested in picking up a few chainsaws.

But there are so many different chainsaw sizes, brands, features, and models of chainsaws available on the market as electric chainsaws and gas-powered chainsaws.

It can be hard to decide what size chainsaw do I need.

This article will help you figure out “what size chainsaw do I need” based on what jobs you need to complete.

You may need an electric or a gas chainsaw based on the task.

A chainsaw is a heavy-duty tool that’s great for felling small trees, felling medium trees, and felling large trees, but it is quite an expensive purchase.

The last thing you want is to buy a smaller gas-powered chainsaw that might not be a good fit for the job.
By finding out what size chainsaw bar length you need, you can get the right chainsaw bar and chain length.

There are a few ways to measure the chainsaw guide bar length and engine size to see what’s appropriate for the job.

How To Choose the Best Size Chainsaw

One of the easiest ways to find out what size chainsaw you should get is to tape-measure the guide bar lengths of your chainsaw bars.

If you’re working with a tree that’s 8′ tall, you can measure the height and add half that measurement to find out how much space you need for your machine.

For example, if you want to clear shrubs, a good rule of thumb is that the chainsaw should be 13″ long to reach high branches.

The Optimal Size for a Chainsaw

The size and length of your chainsaw can save time and money when you’re felling trees.

You will find it easier to walk in a straight line while cutting down trees. Your chainsaw won’t get stuck on branches or other obstacles as often.

It also helps if you have enough space to work but don’t want to buy a chainsaw that’s so large it takes up too much room in your garage or shed.

How to Choose the Right Chainsaw Chain Size?

  • Width
    The chain size can get measured in width, but not always. Different chains have a wide or narrow profile and work better for various jobs.For example, a broad profile chain is okay for cutting down trees with branches wider than 1″.
    On the other hand, a narrow profile chainsaw can help to cut branches with stems that are under 8″ long.
  • Length
    When choosing chain size, you might think the longer the chain is, the better. This isn’t true in every circumstance.
    Too much chain size can reduce your maneuverability and get stuck on a branch as you cut it down.For example, if you’re working with trees that are 8-12″ in diameter, then you can use a length of either 20″ or 30″ to get the job done. But if you have a tree that’s 16″ in diameter, it would be better to use 20-22″ of chain size.
  • Pitch
    You’ll also have to consider pitch when purchasing a new set.
    Different pitches are used for various jobs and can help determine what size chainsaw you should get.For example, a 1/3 pitch is okay for cutting wood and lumber, while a 3/8 is better suited for cutting concrete and other hard materials.
  • Number of teeth per inch
    When you get your chainsaw, one of the first things you should do is check the number of teeth on the chain.
    Different chainsaws have different numbers, but it’s critical to learn which size works best for each job.You can read more about this aspect in our article about choosing chainsaws for your next project.
  • Chainsaw tooth angle
    Many people don’t realize that different saw tooth angles are used to help cut down various materials.For example, a 14-tooth angle works best for cutting wood and lumber, while a 28-tooth degree is better suited for cutting concrete and other hard materials.
  • Saw chain pitch
    The pitch for the chain is a measure of how close the teeth are to one another. For example, a straight chain has no pitch, while a 3/8″ pitch chain has teeth that are closely spaced.The higher the pitch, the more efficient your saw will be at cutting through different materials.

What are the Suggested Chainsaw Sizes for Different Jobs?

Cutting firewood

You’ll want your chainsaw to have a 3/8″ pitch chain for cutting firewood.

Because it’s small, it will be easy to control when you cut down the tree and won’t be too unwieldy to move around in your shed.
You can also change the length of your chain to get a shorter or longer blade into the wood pile.

Removing branches

You’ll need to have at least a 14-tooth saw for removing branches. It will help you cut through the thicker portions of the branch and allow you more control when working with woody stems.

By picking out a 20″ length, you’ll be able to reach higher branches and help reduce the amount of time your job will take.

Trimming limbs

You’ll need at least a 1/2″ pitch saw for pruning limbs. It will help you to create straight cuts and not put the saw into an awkward position as you work your way around the tree.

All these factors will help ensure that your job has been completed the first time.

It’s important to choose a chainsaw with the right size chain so it doesn’t get stuck on thick branches or get bogged down in the heavy brush.

Cutting small trees

For cutting smaller trees, it’s best to use a 1/3 or 3/8″ pitch chain. The smaller the pitch of the chain, the more efficient it will be at cutting down small trees with thinner branches that have been dead for a while.

You might also want to choose a shorter length of between 20″ and 22″ so you can easily remove branches without worrying about getting stuck or damaging your chainsaw.

Cutting medium trees

You’ll need a 21″ length for cutting medium-sized trees. It will allow you to maneuver your chainsaw more efficiently and also help to reduce the amount of time you need to spend cutting down a tree.

You might also think if it’s better to go with a larger or smaller chain for your saw. For example, if you’re trying to cut down a 4-foot tree, it might help to get a chainsaw with a 30″ chain size.

Cutting large trees

You’ll want a chainsaw of 32″ chain length for cutting large trees. You might also need a slightly larger pitch to cut down the tree as quickly and efficiently as possible.

For example, if you have a lot of small trees in your yard or on your property, it would be good to go with a 1/2″ pitch saw.

What If Your Chainsaw Length is Too Big

When you’re doing any home improvement or construction, you will want work going smoothly.

The last thing you want is your chainsaw to be too big and take up too much space in your shed or garage.

That’s why your chainsaw size needs to be suitable for any job.

You could end up spending money on a large chainsaw only to find out later that it wasn’t the best choice for your needs.
Don’t let this happen to you. Make sure your chainsaw is a good fit for your needs by choosing the right size and features.

The chain length, pitch, and the number of teeth are a few things to consider, so it’s critical to keep those in mind when purchasing a new chainsaw.

What If Your Chainsaw Size Is Not Big Enough

The truth is, there are a lot of features that you can choose from when choosing the right size for your saw.
As we’ve mentioned, it’s critical to think about the job you plan on doing and how much space your saw will take up in your shed or garage.

You’ll also want to consider the brand of chainsaw you are buying. Quality brands will often offer more than one size and type of chainsaw so you can pick the best one for your needs.

How Large of a Tree Can a 16-inch Chainsaw Cut?

When researching different chainsaw sizes, it’s critical to understand that the guide bar length of your chainsaw doesn’t just refer to the length of the chainsaw blade.

That’s why some people think they will be able to cut down a large tree with a 16″ chainsaw, while others don’t.

For example, if you have a 16-inch chainsaw, you will need a 16-inch chainsaw bar length and chain to work properly.
That’s why it’s critical to have the right size chainsaw for your needs before making any decisions.

Make sure that you buy a proper-sized chainsaw for any job. This way, you will be able to get the most out of your investment and save money on repair or maintenance later on.
