Understanding Stihl chainsaw chain specifications is essential for safe operation and efficient cutting. Pitch, gauge and number of drive links are three key elements of your Stihl Chains. In this guide, we’ll give you a complete Stihl chainsaw chain size chart for popular models and help you find the right replacement.
Understanding Stihl Chainsaw Chain Sizes
Before diving into specific Stihl models, let’s understand the three key measurements of chainsaw chains first.
Chain Pitch
Pitch is the distance between the chain’s drive links and determines how aggressively your chain cuts. Stihl chainsaws commonly use:
- 3/8 LP (low profile) – Commonly on small homeowner saws
- 3/8 standard – Popular on professional saws
- 0.325″ – Mid-range farm and property saws
Chain Gauge
Gauge is the thickness of the drive links that sit in the guide bar groove. Common gauges for Stihl chainsaws are:
- 0.043″ (1.1mm) – light duty
- 0.050″ (1.3mm) – medium duty
- 0.063″ (1.6mm) – professional duty (most common on Stihl)
Your chain gauge must match your guide bar exactly.
Drive Links
The drive link count in the chain loop is determined by the bar length and sprocket configuration. You can usually find 50DL, 55DL, 74 DL and other numbers of drive links on Stihl chainsaws. Always match the number of drive links when ordering your replacement chain.

- Check Your Stihl Model: Use the chain size chart above to find your chain specifications

Stihl Chain Maintenance Tips
Maintaining your chain in good condition enhances performance and extends the service life of your Stihl chainsaw. Here is what to follow:
- Sharpen Your Chain Regularly: A sharp chain helps cut faster, produces cleaner cuts and uses less fuel.
- Maintain Correct Chain Tension: A loose chain can derail, while an overtight chain can cause excessive wear.
- Apply Quality Chain Oil: Oiling your chainsaw for proper lubrication helps reduce friction and protects both the chain and bar.
- Inspect Before Each Use: Check for damaged teeth, bent links, rust and excessive wear before every use.

Conclusion
Choosing the right chainsaw chain size is crucial for optimal performance of your Stihl chainsaw. Remember not to choose your chainsaw chain by matching the bar length solely. While it is tempting to simply buy a “16-inch chain” for a “16-inch bar,” doing so overlooks the precise engineering of your chainsaw’s cutting system.
