Choosing the correct chainsaw chain may seem straightforward, but getting the wrong gauge or pitch can lead to poor cutting performance, excessive wear, and even safety concerns. Whether you are a homeowner, landscaper, logger, or outdoor power equipment dealer, understanding these measurements is essential.
If you’ve ever struggled with chain fitment or wondered why a chain seemed to dull too quickly or cut unevenly, there is a good chance gauge or pitch was part of the problem. This guide will walk you through everything you need to know so you can match your saw with the proper replacement chain every time.
What Chain Gauge Means and Why It Matters
Gauge refers to the thickness of the drive links, which are the parts of the chain that sit inside the groove of the bar. If the gauge does not match the bar, the chain will not sit properly. This can cause wobbling, increased friction, premature bar and chain wear, and in extreme cases, derailment.
Most chainsaws use one of four common gauge sizes:
- 0.043 inch
- 0.050 inch
- 0.058 inch
- 0.063 inch
Homeowner saws often run smaller gauges like 0.043 or 0.050, while larger professional saws typically use 0.058 or 0.063.
Using the wrong gauge can lead to multiple issues. A chain that is too thin may feel loose in the bar groove and vibrate excessively. A chain that is too thick simply will not fit and may get stuck. Even slight mismatches affect performance, because the chain is designed to track smoothly within the bar. If the drive links cannot move freely, cutting efficiency drops and the saw has to work harder.
Stens and TriLink chains are engineered to strict manufacturing standards, ensuring that gauge measurements remain accurate and consistent. This is especially important for commercial operators who cannot risk downtime caused by incorrect or inconsistent replacement parts.
Understanding Chain Pitch
Pitch is the distance between chain links and determines the size of the chain. It is calculated by measuring the distance between three consecutive rivets and dividing by two. The pitch must match the chainsaw’s sprocket and guide bar. Even if the gauge is correct, the chain will not function properly if the pitch is off.
The most common pitches include:
- 1/4 inch
- 3/8 inch low profile (often labeled 3/8 LP or 3/8 P)
- 0.325 inch
- 3/8 inch standard
- 0.404 inch
Homeowner and mid-range saws often use 3/8 LP or 0.325, while larger professional saws may use 3/8 standard or 0.404 for heavy-duty cutting.
Matching the pitch ensures that the chain meshes correctly with the drive sprocket. If a chain with the wrong pitch is installed, it will not seat properly on the sprocket teeth, causing skipping, uneven wear, and dangerous kickback. Stens and TriLink chains clearly list the pitch on all packaging, making it simple to identify the correct replacement.
How to Measure Chain Gauge and Pitch
Whether you are replacing an old chain or trying to identify a chain from a used saw, taking the correct measurements is important. You can find gauge and pitch information in the owner’s manual, but if that is not available, you can measure the chain directly.
For gauge, use a caliper or a chain gauge tool to measure the thickness of the drive link at its widest point. Using improper tools or trying to eyeball the measurement often leads to incorrect sizing, especially between close values like 0.050 and 0.058.
Pitch can be measured using a ruler or caliper. Measure from the center of one rivet to the center of the third rivet, then divide that number by two. This will give you the chain’s pitch.
For those who prefer a simpler approach, many Stens and TriLink replacement chains list compatible saw models directly on the package or product page. Xtreme OPE will also provide clear listings to help operators easily match chains with their equipment.
Why Bar, Sprocket, Gauge, and Pitch Must Match
A chainsaw is a system, and all components must work together. Mixing incompatible parts can cause serious performance problems. For example:
- A mismatch in pitch between the chain and sprocket prevents smooth rotation.
- A mismatch in gauge between bar and chain causes tracking issues.
- Using the correct chain but pairing it with a worn sprocket increases wear and decreases cutting speed.
To get the best results, always confirm three things:
- Chain pitch matches the sprocket pitch
- Chain gauge matches the bar groove
- Chain length matches the bar length
When all three measurements are correct, the saw will cut efficiently, produce cleaner chips, and experience less wear on both the bar and chain.

Choosing the Right Chain for Your Application
Beyond gauge and pitch, you must also choose the right cutter style. While this guide focuses on sizing, choosing the correct cutter type ensures the chain performs well in your work environment.
Common cutter styles include:
- Semi-chisel: Excellent for dirty wood, frozen wood, and general use
- Full chisel: Fast cutting performance for clean hardwood
- Low-kickback: Designed for safety and ease of use
Most homeowners benefit from semi-chisel or low-kickback chains, while professional users may prefer the speed of full-chisel cutters. Stens and TriLink offer all of these options, making it easy to find the right chain for your needs.
Common Mistakes to Avoid When Selecting a Chain
Many chain issues can be traced back to basic sizing mistakes. Here are some of the most common errors to avoid:
- Mixing different pitches on the same saw
- Assuming all chains with the same bar length are interchangeable
- Choosing a chain based solely on cutter style without checking gauge
- Ignoring sprocket wear when installing a new chain
- Using a bar with a different gauge than the replacement chain
To avoid these issues, double-check your saw’s specifications.
Frequently Asked Questions
How do I know if my chain gauge is incorrect?
If the chain rocks in the bar groove, feels loose even when tensioned properly, or derails frequently, the gauge may not match the bar.
Can I upgrade to a different pitch chain?
Only if you also replace the drive sprocket and use a compatible bar. Pitch must match all three components.
Are Stens and TriLink chains as good as OEM?
Yes. Both brands are known for reliable replacement chains that meet or exceed OEM standards, making them trusted choices for professionals and homeowners.
What happens if the pitch does not match the sprocket?
The chain will skip, wear unevenly, and may cause dangerous kickback. Always match pitch exactly.
Do all chains fit all bars with the same length?
No. Bar length does not determine gauge or pitch. You must match all three measurements for compatibility.
