What Chainsaw Size Is Best For Cutting Firewood?

Chainsaws are indispensable tools for many homeowners today. They make light work of woodcutting jobs that would be backbreaking if you use axes for them. You can use chainsaws to cut down trees, chop firewood, carve wood, and even trim and maintain hedges.

Using firewood for domestic heating has been proven to be one of the cheapest ways to heat your home. To make the task of cutting wood easier, you should get a chainsaw. However, it will not do to get just any chainsaw as they come in different sizes, and each one will cut various materials differently.

Before you purchase a chainsaw that you want to use to cut firewood, you should first consider the width of the trees that you will frequently cut. For medium-sized trees which are about fourteen to sixteen inches wide, you’ll need a chainsaw that is sixteen to eighteen inches long.

You’ll need a longer chainsaw for trees that are larger than that and are in the twenty to twenty-four inches range. However, most homeowners do not cut trees that large except they have enough experience cutting trees, as it is best to leave the cutting of large trees to the professionals. Generally, an eighteen-inch chainsaw is a good size for cutting firewood.

There are three types of chainsaws on the market which are the corded or electric chainsaws, battery-powered or cordless chainsaws, and gasoline chainsaws. Below are the best chainsaws that you can use to cut firewood and their features.
