What Size Chainsaw Do I Need?

Are you tired of battling the wild overgrowth in your backyard, only to end up with aching muscles and a lackluster result? Well, fret no more! It’s time to discover the answer to the age-old question: “What size chainsaw do I need?”

Choosing the right chainsaw is crucial for a successful cutting experience, and it all boils down to power and bar length. Let’s dive into the nitty-gritty details, shall we?

Factors such as the diameter of the wood you typically work with, the frequency of use, and your physical strength all come into play. By considering these factors, you can select a chainsaw that is powerful enough to handle your tasks effortlessly, yet manageable and safe to use.

What Size Chainsaw Do I Need?

Chainsaw Sizes Explained

Chainsaw sizes are not only determined by the bar length but also by the corresponding chain size. The chain must match the bar length and the specific pitch (the distance between the drive links) of the chainsaw. 

Different bar lengths require different chain sizes to ensure proper fit and optimal performance. It’s essential to choose the appropriate chain size for your chainsaw model and bar length to maintain cutting efficiency and safety.

Why Chainsaw Size Matters?

Chainsaw size matters for both safety and efficiency reasons. Here’s why:

1. Safety

The size of a chainsaw directly impacts its handling, control, and the potential risks involved in its operation. A chainsaw that is too large or heavy for the operator can be difficult to maneuver, increasing the likelihood of accidents or loss of control. 

Using a chainsaw with a bar length that exceeds the recommended size for a particular task can also lead to an increased risk of kickback. Kickback occurs when the chain binds or hits something, jerking the saw back toward the operator. Use the right chainsaw size for better control, less risk, and more safety.

2. Efficiency

Choosing the right chainsaw size ensures optimal cutting efficiency. Using a chainsaw with a bar length that matches the size of the wood being cut allows for more effective and efficient cutting. A small chainsaw will struggle to cut large logs or trees, making the job harder and slower.

Conversely, using a chainsaw that is too large for smaller jobs can be cumbersome and inefficient, wasting time and energy. Choose the right chainsaw size for efficient and effective cutting.

Decoding Chainsaw Sizes: What the Numbers Mean?

Decoding chainsaw sizes involves understanding what the numbers associated with them mean. Here’s a breakdown of the key elements:

1. Bar Length

The primary number associated with chainsaw sizes represents the bar length. For example, in a chainsaw with a size of 18 inches, the number 18 refers to the length of the guide bar, which is the metal bar around which the cutting chain is wrapped. 

The bar length determines the maximum cutting diameter that the chainsaw can handle. You can see how to measure the chainsaw chain visually here.

2. Measurement Unit

The bar length is typically measured in inches, although other measurement units, such as centimeters, may be used in some regions. It is important to ensure consistency between the unit of measurement used for the chainsaw size and any other specifications or accessories related to the chainsaw.

3. Cutting Capacity

The bar length indicates the maximum cutting capacity of the chainsaw. It represents the distance from the tip of the bar to the point where the chain enters the housing. Essentially, it determines the size of logs or trees that can be cut in a single pass. 

The cutting capacity is roughly twice the length of the bar, as the chainsaw can cut through wood equal to its bar length when the bar is fully plunged into the material.

4. Specialty Sizes

Apart from the standard bar lengths, there are also specialized chainsaw sizes available. These may include shorter bar lengths for light pruning and trimming tasks, as well as longer bar lengths for professional-grade applications, such as felling large trees or milling lumber.

Choosing the Right Chainsaw Size for Different Tasks

To achieve optimal performance and safety, selecting the right chainsaw size is crucial for achieving optimal performance and safety. 

The most common chainsaw bar sizes are 12 to 20 inches, but they come in sizes as large as 72 inches, typically for professionals

Here are some guidelines to consider when selecting a chainsaw size based on common tasks:

1. Pruning and Limbing

For light pruning and limbing tasks, a smaller chainsaw size is typically more suitable. Bar lengths ranging from 8 to 14 inches are commonly used for these types of jobs. Smaller chainsaws offer greater maneuverability and control in tight spaces and are ideal for cutting branches and small limbs.

2. Firewood Cutting

Cutting firewood often involves working with medium-sized logs. Bar lengths between 14 and 18 inches are commonly used for this task. These sizes provide a good balance of cutting capacity and maneuverability, allowing for the efficient processing of firewood.

3. Chainsaw Sizes for Heavy-Duty Cutting and Logging

The right chainsaw size is essential for heavy-duty cutting and logging. For larger trees, professional loggers typically opt for chainsaws with bar lengths ranging from 18 to 36 inches. ILarge chainsaws can cause more damage, while small ones are better for smaller trees.

4. Tree Felling and Bucking

Felling larger trees and bucking them into manageable pieces require a chainsaw with a longer bar length. Bar lengths in the range of 18 to 24 inches are commonly used for these tasks. Longer bars cut larger logs more efficiently.

5. Professional Logging and Heavy-Duty Tasks

Professional loggers and individuals undertaking heavy-duty tasks may require chainsaws with even longer bar lengths. Bar lengths exceeding 24 inches are available for these specialized applications. Large chainsaws cut down big trees and process heavy logs.

6. Operator Experience and Physical Strength

Consider your experience level and physical strength when selecting a chainsaw size. Novice users or those without much physical strength may find smaller chainsaws easier to manage and operate. Larger chainsaws require more experience and strength to operate effectively.
