How Do I Measure Chainsaw Chain? (Chain Gauge Secrets Revealed)

Measuring a chainsaw chain correctly is crucial for safety, performance, and longevity of both your saw and the chain itself. Mismatched chains can damage the saw, cause dangerous kickback, and drastically reduce cutting efficiency. One of the most critical aspects of chain measurement is the gauge. This article will break down the mysteries of chainsaw chain gauge and provide a step-by-step guide to measuring it accurately.

Why Measuring Chainsaw Chain Matters

Before diving into the specifics, it’s important to understand why accurate chain measurement is so vital.

Safety: Using the wrong chain can lead to chain breakage, kickback, and other dangerous situations.
Performance: A properly fitted chain ensures optimal cutting efficiency and reduces strain on the saw’s engine.
Longevity: Using the correct chain helps prolong the life of both the chain and the chainsaw itself.
Cost-Effectiveness: Avoiding damage caused by using the wrong chain saves money in the long run.

Understanding Chainsaw Chain Terminology

To accurately measure a chainsaw chain, it’s essential to understand the key terminology involved:

Pitch: The distance between any three consecutive rivets on the chain, divided by two. It determines the size of the chain and its compatibility with the sprocket.
Gauge: The thickness of the drive links, which fit into the guide bar groove. This is our primary focus.
Drive Links: The small metal pieces on the chain that engage with the sprocket and pull the chain around the guide bar.
Cutter: The cutting teeth on the chain that remove wood.
Tie Straps: Connect the cutters and drive links.
Rivet: The small metal pins that hold the chain components together.

Decoding the Chain Gauge: The Secrets Revealed

The chain gauge is the thickness of the drive links that fit into the groove of the guide bar. It’s measured in thousandths of an inch (e.g., .050″, .058″, .063″). Using the correct gauge is crucial because a chain that is too thick won’t fit into the guide bar, while a chain that is too thin will wobble and potentially come off.

Why Chain Gauge Matters

Proper Fit: Ensures the chain fits snugly and securely within the guide bar groove.
Optimal Performance: Prevents the chain from wobbling or derailing, leading to smoother, more efficient cutting.
Safety: Reduces the risk of chain breakage or kickback.
Guide Bar Compatibility: Matches the chain to the specific guide bar, ensuring they work together correctly.

How to Measure Chainsaw Chain Gauge: A Step-by-Step Guide

Here’s how I approach measuring chainsaw chain gauge, based on years of experience in the field:

Locate Existing Markings: The easiest way to determine the chain gauge is to look for markings on the chain itself or on the guide bar. The gauge is often stamped on the drive link or the base of the guide bar. Look for numbers like .050, .058, or .063. This is my first stop – saves a lot of time if it’s legible!
Use a Caliper (The Most Accurate Method): If the markings are worn or absent, the most accurate method is to use a caliper. Here’s how:
- Clean the Chain: Make sure the drive links are clean and free of debris.
- Measure the Drive Link: Place the caliper jaws on either side of a drive link, ensuring you’re measuring the thickness where it fits into the guide bar groove.
- Read the Measurement: The caliper will display the thickness in inches or millimeters. If it’s in millimeters, convert it to inches (1 mm = 0.03937 inches).
Use a Gauge Tool: Specialized gauge tools are available for measuring chainsaw chain gauge. These tools typically have slots of different widths corresponding to common chain gauges.
- Insert the Drive Link: Try inserting a drive link into each slot until you find the one that fits snugly.
- Read the Gauge: The tool will indicate the chain gauge based on the slot that fits the drive link.
Consult the Chainsaw or Guide Bar Manual: The chainsaw or guide bar manual will usually specify the correct chain gauge for your equipment. This is a reliable source of information, especially if you’re unsure about the chain markings.

Common Chainsaw Chain Gauges

Here are the most common chainsaw chain gauges:

.043″ (1.1 mm): Often found on smaller, lightweight chainsaws.
.050″ (1.3 mm): A very common gauge, used on a wide range of chainsaws.
.058″ (1.5 mm): Commonly used on medium-sized chainsaws.
.063″ (1.6 mm): Typically found on larger, professional-grade chainsaws.

Interpreting the Gauge Measurement

Once you’ve measured the chain gauge, you need to interpret the measurement correctly. The gauge should match the gauge specified for your chainsaw’s guide bar. Using a chain with the wrong gauge can lead to:

Chain Slippage: If the chain is too thin, it may wobble and come off the guide bar.
Guide Bar Damage: A chain that is too thick can damage the guide bar groove.
Poor Cutting Performance: An improperly fitted chain will not cut efficiently.

How Gauge Relates to Other Chain Measurements

Chain gauge is closely related to other chain measurements, such as pitch and drive link count.

Pitch: While pitch determines the overall size of the chain, gauge determines how well it fits into the guide bar.
Drive Link Count: The number of drive links determines the length of the chain, which must match the length of the guide bar.

Personal Experience and Insights

In my early days of logging, I made the mistake of using a chain with the wrong gauge. The chain kept slipping off the guide bar, and I spent more time reattaching it than actually cutting wood. It was frustrating and time-consuming. I quickly learned the importance of accurate chain measurement and the value of using the correct gauge.

I once worked on a project where we had to fell a large number of trees in a remote area. We had several chainsaws of different sizes, each requiring a specific chain gauge. To avoid confusion, I created a chart that listed each chainsaw and its corresponding chain specifications, including gauge, pitch, and drive link count. This simple chart saved us a lot of time and prevented costly errors.

Case Study: Improving Efficiency Through Correct Chain Selection

I conducted a small case study on a firewood preparation project to demonstrate the impact of using the correct chain gauge. We used two identical chainsaws, one with the correct chain gauge (.050″) and one with an incorrect gauge (.058″). We timed how long it took to cut through a stack of logs with each saw.

Chainsaw with Correct Gauge (.050″): Average cutting time: 15 minutes.
Chainsaw with Incorrect Gauge (.058″): Average cutting time: 22 minutes.

The chainsaw with the correct gauge was significantly faster and more efficient. The chainsaw with the incorrect gauge struggled to cut through the logs, and the chain frequently slipped off the guide bar. This case study clearly illustrates the importance of using the correct chain gauge for optimal performance.
