Measure Chainsaw Chain: A Comprehensive Guide
Hey guys! Ever found yourself scratching your head wondering how to measure a chainsaw chain? It's not as straightforward as measuring, say, a piece of wood, but don't worry, I'm here to break it down for you. Chainsaw chains have a unique sizing system that involves three key measurements: pitch, gauge, and the number of drive links. Luckily, these numbers are often conveniently located on the side of the chainsaw bar. In this comprehensive guide, we'll dive deep into each of these measurements, show you exactly how to find them, and explain why they're so important. So, grab your chainsaw (safely, of course!), and let's get started!
Understanding Chainsaw Chain Measurements
When it comes to understanding chainsaw chain measurements, it's crucial to grasp the significance of each component. The three primary measurements – pitch, gauge, and drive link count – work together to ensure the chain fits and functions correctly on your chainsaw. Think of it like finding the perfect shoe size; too big or too small, and you're going to have a bad time. Similarly, if your chain doesn't match your saw's specifications, you'll run into performance issues and potential damage. So, what exactly do these measurements mean?
Pitch
Let's start with the pitch. Simply put, the pitch is the average distance between any three consecutive rivets on the chain, divided by two. It essentially indicates the size of the chain. You might see pitch measurements like 0.325 inch, 0.375 inch (or 3/8 inch), or 0.404 inch. The pitch must match the sprocket on your chainsaw to ensure proper engagement and smooth cutting. A mismatched pitch can lead to the chain slipping or even jumping off the bar, which is not only frustrating but also dangerous. To find the pitch, you'll often find it stamped on the chainsaw bar near the mounting studs. Alternatively, you can manually measure the distance between three rivets and divide by two, but checking the bar is much easier and more accurate.
Gauge
Next up is the gauge. The gauge refers to the thickness of the drive links – those little teeth that fit into the groove of the chainsaw bar. It's measured in thousandths of an inch, and common gauges include 0.043 inch, 0.050 inch, 0.058 inch, and 0.063 inch. The gauge of your chain must match the width of the bar groove for the chain to run smoothly. If the gauge is too small, the chain will wobble and may derail. If it's too large, the chain won't fit into the groove at all. Like the pitch, the gauge is usually stamped on the chainsaw bar. Make sure you match this number precisely when buying a new chain.
Drive Links
Finally, we have the number of drive links. This is simply the count of the drive links on your chain. Each drive link fits into the bar groove and engages with the sprocket. The number of drive links determines the overall length of the chain and ensures it fits properly around the bar. You'll need to know this number when purchasing a replacement chain. Counting the drive links can seem tedious, but it's crucial for getting the right fit. The number of drive links isn't always stamped on the bar, so you'll often have to count them manually. Don't worry, I'll show you how in the next section.
Understanding these three measurements – pitch, gauge, and drive link count – is fundamental to maintaining your chainsaw and ensuring its optimal performance. By knowing how to identify these measurements, you can confidently select the correct replacement chain and keep your saw running smoothly.
Step-by-Step Guide to Measuring Your Chainsaw Chain
Now that we've covered the basics, let's get into the nitty-gritty of how to measure your chainsaw chain step-by-step. Don't worry, it's not rocket science, but paying attention to detail is key. Whether you're replacing a worn-out chain or just want to have a spare on hand, knowing these measurements is essential. So, grab your gloves (for safety!) and let's get started!
Step 1: Locate the Markings on the Chainsaw Bar
The first and often easiest step is to locate the markings on the chainsaw bar. Most manufacturers stamp the pitch and gauge directly onto the bar, usually near the mounting studs or the saw's nose. Look for numbers like "3/8" or "0.375" for the pitch and "0.050" or "0.058" for the gauge. These markings are your best friend, saving you the hassle of manual measurement. However, keep in mind that these markings can wear off over time, especially with heavy use. If you can clearly see these numbers, write them down – you're already halfway there! If the markings are faded or missing, don't panic; we've got other methods.
Step 2: Manually Measure the Pitch (If Necessary)
If you can't find the pitch on the bar, you'll need to manually measure the pitch. This involves a bit of math, but it's not too complicated. Here's how:
- Identify three consecutive rivets on the chain. These are the round pins that hold the chain segments together.
- Measure the distance between the first and third rivet. Use a ruler or measuring tape for this.
- Divide the measurement by two. The result is your chain's pitch.
For example, if the distance between three rivets is 0.75 inches, dividing that by two gives you a pitch of 0.375 inches (or 3/8 inch). Make sure you're measuring accurately, as even small discrepancies can lead to the wrong chain size.
Step 3: Identify the Gauge (If Necessary)
Similar to the pitch, if the gauge isn't marked on the bar, you'll need to figure it out manually. The gauge is the trickiest to measure without a specialized tool, but here's the general idea. The gauge is the thickness of the drive links – the parts of the chain that fit into the groove on the bar. You can try using a caliper to measure the thickness of a drive link, but this can be challenging and not always precise. If you're unsure, it's often best to consult your chainsaw's manual or contact the manufacturer for the correct gauge. Using the wrong gauge can cause the chain to bind or derail, so accuracy is crucial here.
Step 4: Count the Drive Links
Now comes the most hands-on part: counting the drive links. This is the only measurement you'll almost always have to do manually, as it's rarely stamped on the bar. Here's how to do it efficiently:
- Remove the chain from the chainsaw (remember to wear gloves!).
- Lay the chain out on a flat surface.
- Start at one drive link and carefully count each one. It's helpful to mark the starting link with a piece of tape or a marker to avoid losing track.
- Count all the way around the chain until you reach your starting point.
It's essential to be accurate here, as the number of drive links directly corresponds to the chain's length and how it fits on the bar. A wrong count can result in a chain that's too loose or too tight.
Step 5: Record Your Measurements
Once you've gathered all the measurements – pitch, gauge, and the number of drive links – record your measurements. Write them down in a safe place or store them in your phone. This information will be invaluable when you're shopping for a new chain. Having these numbers handy will save you time and ensure you get the right fit the first time.
By following these steps, you'll be able to confidently measure your chainsaw chain and ensure you're using the correct size for your saw. Remember, safety first – always wear gloves when handling the chain, and if you're ever unsure, consult your chainsaw's manual or a professional.
Why Accurate Measurements Matter
So, we've gone through the steps of measuring a chainsaw chain, but you might be wondering, "Why do accurate measurements matter?" It's a fair question! Using the wrong chain on your chainsaw can lead to a whole host of problems, from poor cutting performance to potential safety hazards. Let's break down why getting those measurements right is so crucial.
Optimal Cutting Performance
First and foremost, accurate measurements ensure optimal cutting performance. A chain that's the wrong size simply won't cut as efficiently. If the pitch doesn't match the sprocket, the chain won't engage properly, leading to jerky cuts and increased wear on both the chain and the saw. A gauge that's too small will cause the chain to wobble, while a gauge that's too large won't fit in the bar groove at all. And if the number of drive links is off, the chain will either be too loose (and prone to derailing) or too tight (putting excessive strain on the saw's motor). Using the correct chain size guarantees smooth, efficient cutting, saving you time and effort.
Safety Considerations
Beyond performance, safety is a major concern when it comes to chainsaw chain measurements. A chain that doesn't fit properly is a safety hazard. A loose chain is more likely to derail during operation, which can be extremely dangerous. A tight chain can overheat and potentially break, sending metal fragments flying. Using the wrong chain can also put undue stress on the saw's motor and other components, increasing the risk of mechanical failure. Chainsaw work is inherently dangerous, so it's essential to eliminate any unnecessary risks by using the correct chain size.
Preventing Damage to Your Chainsaw
Using the wrong chain can also lead to preventable damage to your chainsaw. A mismatched chain can put excessive strain on the saw's motor, clutch, and bar, leading to premature wear and tear. This can result in costly repairs or even the need to replace the entire saw. By using the correct chain, you'll extend the lifespan of your chainsaw and keep it running smoothly for years to come. Think of it as an investment in the long-term health of your tool.
Cost Savings
Finally, accurate measurements can save you money. Buying the wrong chain is not only frustrating but also a waste of money. You'll have to go through the hassle of returning it and ordering the correct one. Plus, as mentioned earlier, using the wrong chain can damage your saw, leading to expensive repairs. Investing a few minutes to accurately measure your chain can save you both time and money in the long run. It's a small effort that pays off big time.
In conclusion, taking the time to accurately measure your chainsaw chain is essential for optimal cutting performance, safety, preventing damage to your saw, and saving money. It's a fundamental skill for any chainsaw user, and with this guide, you're well-equipped to tackle the task with confidence.

Consider the Chain Type
Next, consider the chain type. Chainsaw chains come in various designs, each suited for different cutting tasks and conditions. Some common types include:
- Full Chisel Chains: These chains have square-cornered teeth that cut quickly and efficiently through clean wood. They're ideal for professional users and experienced homeowners, but they require more frequent sharpening and are more prone to kickback.
- Semi-Chisel Chains: Semi-chisel chains have rounded corners on their teeth, making them more durable and less prone to kickback than full-chisel chains. They're a good all-around choice for a variety of cutting tasks.
- Low-Kickback Chains: These chains are designed with features that reduce the risk of kickback, a dangerous phenomenon where the saw suddenly jerks backward. They're a great option for beginners and anyone concerned about safety.
Consider the type of cutting you'll be doing most often and choose a chain that suits your needs. If you're primarily cutting clean wood, a full-chisel chain might be a good choice. If you're dealing with dirty or knotty wood, a semi-chisel chain might be more durable. And if you're new to chainsaws or prioritize safety, a low-kickback chain is a smart choice.
Read Reviews and Seek Recommendations
Before making a purchase, read reviews and seek recommendations. Online reviews can provide valuable insights into the performance and durability of different chain brands and models.
