Knowledge Based

The chainsaw chain length calculator offers to calculate the length of your tool in the easiest way possible. What homeowners have to do is to simply put the chain pitch values, drive link number, and bar length into the calculator and click on the Calculate button. The calculator will yield results showing the exact length of the chain. You can, therefore, adjust the length of the chain as per your needs and requirements.


How to Use Chainsaw Chain Length Calculator?

Step 1: Understand the Purpose 

A chainsaw chain length calculator helps determine the appropriate chain length for your chainsaw based on the chain pitch, drive link number, and bar length. This information is crucial for ensuring the chain fits your tool properly and operates safely.

Step 2: Access the Chain Length Calculator 

Ensure that you have a stable internet connection or the necessary app installed on your device before you access the calculator on Chainsaw Guru

Step 3: Input the Required Values

Enter the following values into the designated fields of the calculator:

  • Chain Pitch: Input the chain pitch measurement in inches. The chain pitch is the distance between any three consecutive rivets on the chain divided by two. Common examples include 0.325″, 3/8″, or 0.404″.
  • Drive Link Number: Enter the number of drive links on the chain. This information can typically be found on the chainsaw’s user manual or by counting the individual drive links on the existing chain. You can utilize a chainsaw drive link calculator for that purpose as well. 
  • Bar Length: Input the length of the chainsaw’s guide bar in inches. This measurement refers to the distance from the tip of the bar to the point where the chain exits the bar. Common bar lengths include 14”, 16″, 18”, 20″, or 24″.

Step 4: Calculate the Chain Length 

After entering the required values, click the “Calculate” button available just below the required values option. The calculator will process the data and provide you with the exact chain length required for your chainsaw based on the given parameters.

Step 5: Review the Results 

Once the calculation is complete, the calculator will display the precise chain length needed for your chainsaw. Take note of this value for reference.

Step 6: Verify Compatibility 

Compare the calculated chain length with the chain length capacity specified in your chainsaw’s user manual or manufacturer’s recommendations. Ensure that the calculated length falls within the acceptable range to ensure proper functioning and safety.

Step 7: Obtain the Correct Chain Length 

Using the calculated chain length, you can now purchase a replacement chain that matches the required specifications. When acquiring a new chain, double-check that the chain pitch, drive link number, and bar length match the calculated values.

Frequently Asked Questions

What is the formula for chain length?

The formula for chain length in a chainsaw can be determined using the pitch of the chain, the number of drive links, and the pitch of the sprocket. The formula is generally: Chain length = (Number of Drive Links / 2) * Pitch.

How long is a 20-inch chainsaw bar?

A 20-inch chainsaw bar refers to the measurement from the tip of the bar to the point where it enters the saw’s housing. This size is commonly used for medium to heavy-duty cutting tasks, including felling medium-sized trees, limbing, and bucking.

What is a 20-inch chainsaw good for?

A 20-inch chainsaw is suitable for various tasks, including cutting medium-sized trees, handling firewood, and managing larger property maintenance projects. It strikes a balance between power and maneuverability, making it a versatile tool for both homeowners and professionals.

What is a 24-inch chainsaw used for?

A 24-inch chainsaw is typically used for more heavy-duty tasks, such as felling large trees and processing large amounts of firewood. It is commonly employed in forestry and professional logging operations due to its increased cutting capacity and ability to handle more substantial and demanding cutting jobs.

Final Words

By following these steps, homeowners can effectively use the chain length calculator to determine the exact chain length needed for their chainsaw based on the chain pitch, drive link number, and bar length.
