🛠️ The Three Critical Numbers: Deciphering the Oregon Chainsaw Chain Size Chart

Before purchasing an Oregon Chainsaw Chain of any length (e.g., 16-Inch, 18-Inch, 20 Inch), you must understand and match three non-negotiable specifications. The Oregon Chainsaw Chain size chart relies entirely on these:

1. Pitch (The Size)

• Definition: The average distance between any three consecutive rivets divided by two. This must match the drive sprocket on your saw and the nose sprocket on your guide bar.
• Common Oregon Pitches:
  • 3/8″ Low Profile (LP) or Mini: Most common for small consumer saws and battery saws.¹
  • .325″ (pronounced “three-two-five”): A professional standard for mid-sized saws (40cc-60cc).
  • 3/8″ (Standard): Used for powerful, professional-grade saws and longer bars.²

2. Gauge (The Thickness)

• Definition: The thickness of the drive links that ride inside the bar groove. Mismatching the gauge causes the chain to either bind or wobble dangerously.
• Common Oregon Gauges: .050″ (1.3mm), .058″ (1.5mm), and .063″ (1.6mm).³ Smaller saws often use .043″ (1.1mm) for narrow-kerf cutting.

3. Drive Links (The Length)

• Definition: The total count of drive links (the small, pointed tabs on the bottom of the chain). This determines the specific length for a given bar.

Tip: The easiest way to find these three numbers is to look at the Oregon Chainsaw Chain catalog guide, which cross-references your saw’s make and model, or look for the pitch and gauge numbers stamped directly on the guide bar or the old drive links.

🌲 Universal Compatibility: Oregon Chainsaw Chains for Husqvarna and Stihl

One of Oregon’s greatest strengths is its ability to provide chains that are perfectly compatible with the two biggest OEM players. When searching for Oregon chainsaw chains for Husqvarna or Oregon chainsaw chains for Stihl, you are essentially looking for a chain that matches the bar mount and the chain specs.

Oregon Chainsaw Chains for Husqvarna

Husqvarna saws commonly use the .325″ pitch or the standard 3/8″ pitch.⁴ Oregon’s part numbering system often references the required specs directly:

• Chisel Cutter Series (e.g., 72LPX or 73LPX): These are full-chisel cutters, similar to Husqvarna’s professional X-Cut C83/C85 chains, offering fast, aggressive cutting for dedicated users.
• ControlCut Series (e.g., 95TXL): A high-performance, narrow-kerf option that is popular on modern Husqvarna saws as it maximizes the saw’s power efficiency.

Oregon Chainsaw Chains for Stihl

Oregon chainsaw chains for Stihl models are easily found using Oregon’s cross-reference charts, which match Stihl’s Picco (P), Rapid Micro (RM), and Rapid Super (RS) chain designations to the corresponding Oregon series.

• Low Profile/Homeowner Chains (e.g., 90PX/91PX): These replace Stihl’s Picco Micro (PM) chains and are the go-to for small saws like the MS 170 and MS 180.
• Professional Chains (e.g., 72DX/73DX): These are equivalent to Stihl’s professional .3/8″ pitch chains, designed for high-power saws (like the MS 362 and up).

The key when fitting Oregon Chainsaw Chains for Stihl is ensuring the guide bar mount and drive link count match, as Stihl guide bars can sometimes require a unique link count compared to aftermarket bars of the same nominal length.

📈 Sizing Guide: From 16-Inch to 24 Inch

The length of the chain, defined by the drive link count, determines its primary use. Oregon supplies chains for every standard length:

Oregon Chainsaw Chains 16-Inch (The Versatile Standard)

• Typical Use: Home firewood, storm cleanup, mid-sized battery saws.
• Common Specs: Often 3/8″ LP with a .050″ gauge (e.g., 91PX057G – 57 links) or .325″ with a .050″ or .058″ gauge (e.g., 20BPX066G – 66 links).⁵ The 16-Inch chain is arguably the most purchased length.

Oregon Chainsaw Chains 18-Inch (The Heavy Homeowner/Mid-Range Pro)

• Typical Use: Heavy-duty property maintenance, felling medium trees, farm use.
• Common Specs: Transitioning to .325″ or standard 3/8″ pitch, often with .058″ or .050″ gauge.⁶ The link count is typically 66 or 68 links. The 18-Inch length gives the user more reach without a massive jump in weight.

Oregon Chainsaw Chains 20 Inch (The Firewood Processor)

• Typical Use: Processing large amounts of firewood, running on 50cc-70cc professional saws.
• Common Specs: Usually standard 3/8″ pitch or .325″ pitch with a .050″ or .058″ gauge.⁷ The common link count is 72 or 78 links. Oregon Chainsaw Chains 20 Inch requires a saw with sufficient engine/motor power to drive the longer length efficiently.

Oregon Chainsaw Chains 24 Inch (The Logger/Arborist)

• Typical Use: Felling large diameter trees, professional logging operations.
• Common Specs: Almost exclusively standard 3/8″ pitch with .058″ or .063″ gauge. The link count is commonly 84 links.⁸ Oregon Chainsaw Chains 24 inch are often sold in full-chisel type (e.g., 73LPX) for maximum cutting speed.

📚 The Oregon Chainsaw Chain Catalog and Chain Families

The Oregon Chainsaw Chain catalog organizes its chains into “families” based on design, cutter type, and intended use. Knowing these names helps you choose the best chain for your application:

1. AdvanceCut™ (e.g., 90PX, 91PX): Designed for homeowners and occasional users. Features a low-vibration, low-kickback design, making it safe and easy to maintain.
2. ControlCut™ (e.g., 20BPX, 21BPX): A medium-performance, general-purpose chain. Provides a good balance of speed, durability, and low vibration for mid-sized saws.
3. PowerCut™ (e.g., 72LPX, 73LPX): Oregon’s professional-grade, high-performance line. These chains typically feature a full-chisel cutter for aggressive, fast cutting, targeting arborists and loggers.

Regardless of whether you need an Oregon Chainsaw chains 16-Inch or an Oregon Chainsaw chains 24 inch, selecting the right family based on your expertise and saw size is as important as matching the specs.
