How Big of Chainsaw Do I Need? (Top Sizes for Everyday Cutting)

Alright, let’s dive into the world of chainsaws and wood processing, and figure out just what size saw you need to tackle your projects!

Remember that old Victorian fixer-upper my cousin bought? Initially, it was all excitement and dreams of HGTV glory. But then reality hit – rotting porch supports, overgrown trees threatening the foundation, and a fireplace that hadn’t seen action since the Eisenhower administration. The first weekend was spent staring at a tangled mess of branches, wondering if a handsaw and a lot of wishful thinking would cut it (pun intended!).

It was then that the question, “How big of a chainsaw do I need?” became paramount. He ended up borrowing my trusty 20-inch saw, and while it tackled the smaller trees and branches, the larger diameter logs for firewood were a real struggle. That experience, and many others like it, taught me the importance of choosing the right tool for the job. And that starts with understanding the intended use of your chainsaw.

How Big of a Chainsaw Do I Need? (Top Sizes for Everyday Cutting)

Choosing the right chainsaw can feel overwhelming. Too small, and you’ll be fighting the wood every step of the way. Too big, and you’ll be lugging around unnecessary weight and power. The key is to match the saw to the task. Let’s break down the common chainsaw sizes and their ideal applications.

1. Understanding Chainsaw Sizes: Bar Length and Engine Displacement

Before we jump into specific sizes, it’s important to understand the two primary measurements that define a chainsaw’s size:

• Bar Length: This is the length of the metal bar that guides the chain. It determines the maximum diameter of wood you can safely cut in a single pass. Generally, you want a bar that’s at least two inches longer than the thickest wood you plan to cut.
• Engine Displacement: Measured in cubic centimeters (cc), this indicates the engine’s size and power. A larger engine displacement typically means more power and the ability to handle tougher jobs.

2. Small Chainsaws (10-14 inch bar, 30-40cc engine)

These are your lightweight, maneuverable options. Think of them as the “pruning shears” of the chainsaw world.

• Ideal for:
  • Light pruning of small branches (under 6 inches in diameter)
  • Limbing small trees
  • Cutting small firewood (under 8 inches in diameter)
  • General yard maintenance
• Pros:
  • Lightweight and easy to handle
  • Relatively inexpensive
  • Easy to start and maintain
• Cons:
  • Limited cutting capacity
  • Not suitable for felling large trees or cutting large firewood
  • Can be underpowered for denser hardwoods
• My Experience: I used a 12-inch chainsaw for years primarily for pruning my fruit trees. It was perfect for that task, zipping through branches with ease. However, when I tried to use it to cut up a fallen oak limb, it struggled mightily. That’s when I realized the importance of having a larger saw for bigger jobs.
• Project Metrics:
  • Time per Cut: For branches under 4 inches, expect a cut time of 5-10 seconds.
  • Fuel Consumption: These saws are very fuel-efficient, typically consuming around 0.5 liters of fuel per hour.
  • Maintenance: Chain sharpening is crucial. A dull chain will significantly increase cutting time and strain the engine. I recommend sharpening the chain after every 2-3 hours of use.

3. Medium Chainsaws (16-18 inch bar, 40-50cc engine)

This is the sweet spot for many homeowners. They offer a good balance of power and maneuverability, making them versatile for a variety of tasks.

• Ideal for:
  • Felling small to medium-sized trees (up to 12 inches in diameter)
  • Cutting firewood (up to 16 inches in diameter)
  • Storm cleanup
  • General property maintenance
• Pros:
  • Versatile and can handle a wide range of tasks
  • Good power-to-weight ratio
  • More durable than small chainsaws
• Cons:
  • Can be tiring to use for extended periods
  • May struggle with very dense hardwoods
• My Experience: I upgraded to an 18-inch chainsaw when I started cutting more firewood. It made a huge difference in efficiency. I could fell smaller trees and buck larger logs with much less effort. I also found it to be much more effective for storm cleanup, easily cutting through fallen branches and debris.
• Project Metrics:
  • Felling Time: Expect to fell a 10-inch diameter softwood tree in 2-3 minutes. Hardwood will take longer.
  • Firewood Production Rate: With proper technique, you can expect to produce around 1-2 cords of firewood per day with a medium-sized chainsaw.
  • Chain Wear: Chain wear will be higher than with a small chainsaw, especially when cutting hardwoods. Inspect the chain regularly and sharpen it as needed. I also recommend having a spare chain on hand.

4. Large Chainsaws (20-24 inch bar, 50-60cc engine)

These are the workhorses of the chainsaw world. They’re designed for demanding tasks like felling large trees and cutting large firewood.

• Ideal for:
  • Felling large trees (up to 20 inches in diameter)
  • Cutting large firewood (over 16 inches in diameter)
  • Professional logging
  • Clearing large areas of land
• Pros:
  • Powerful and can handle tough jobs
  • Durable and built to last
  • Can significantly increase productivity
• Cons:
  • Heavy and can be tiring to use
  • More expensive than smaller chainsaws
  • Require more maintenance
• My Experience: I once helped a friend clear a heavily wooded lot for a new building project. We used a 24-inch chainsaw to fell some massive oak trees. It was definitely the right tool for the job. However, I quickly learned that using a large chainsaw requires proper technique and physical conditioning. It’s not for the faint of heart!
• Project Metrics:
  • Felling Time (Large Trees): Felling a 18-inch diameter hardwood tree can take 5-10 minutes, depending on the species and the tree’s condition.
  • Wood Volume Yield: When felling large trees, maximizing wood volume yield is crucial. Proper felling techniques and bucking strategies can significantly increase the amount of usable wood.
  • Equipment Downtime: Large chainsaws are more prone to downtime due to their increased complexity. Regular maintenance and proper operation are essential to minimize downtime.

5. Extra-Large Chainsaws (24+ inch bar, 60+cc engine)

These are the beasts of the chainsaw world, reserved for professionals and those tackling the most demanding jobs.

• Ideal for:
  • Felling very large trees (over 24 inches in diameter)
  • Professional logging of old-growth forests
  • Milling lumber
• Pros:
  • Unmatched power and cutting capacity
  • Can handle the largest trees and logs
• Cons:
  • Extremely heavy and difficult to handle
  • Very expensive
  • Require specialized training and experience
• My Experience: I haven’t personally used a chainsaw this large extensively, but I’ve witnessed professional loggers using them in the Pacific Northwest. The sheer size and power of these saws are awe-inspiring. They’re capable of felling trees that are several feet in diameter. However, they also require a high level of skill and experience to operate safely and effectively.
• Project Metrics:
  • Safety Incidents: Due to the inherent risks associated with operating such large equipment, safety is paramount. A key metric is the number of safety incidents per operating hour.
  • Operational Costs: These saws have high operational costs, including fuel, maintenance, and chain replacement. Tracking these costs is essential for profitability.
  • Lumber Yield Efficiency: When using these saws for milling lumber, maximizing lumber yield efficiency is critical. This involves careful planning and precise cutting techniques.
