How Do You Measure Bar Length on a Chainsaw (3 Pro Tips)

Many people believe the bar length of a chainsaw is simply the length of the metal bar itself. While that’s partly true, it doesn’t tell the whole story. Actually measuring your chainsaw bar length accurately is crucial for everything from buying the correct replacement chain to understanding the cutting capacity of your saw. In this article, I’ll share my insights and three pro tips for measuring your chainsaw bar length like a seasoned pro. Plus, I’ll delve into the costs associated with different bar lengths and how they impact your overall wood processing budget.

How Do You Measure Bar Length on a Chainsaw (3 Pro Tips)

Understanding how to accurately measure your chainsaw bar length is more than just a technicality; it’s fundamental to safe and efficient operation. The bar length determines the size of wood you can realistically cut and directly impacts the type of chain you need.

Why Bar Length Matters

Before diving into the measuring tips, let’s quickly cover why bar length is so important.

• Chain Compatibility: The chain must match the bar length. An incorrectly sized chain won’t fit properly and will be dangerous to use.
• Cutting Capacity: The bar length determines the maximum diameter of wood you can cut in a single pass.
• Saw Performance: Using a bar length that is too long for your chainsaw’s engine can strain the motor and reduce its lifespan.
• Safety: A properly sized bar improves the saw’s balance and makes it easier to control, enhancing safety.

Pro Tip 1: Understanding the True Measuring Point

The advertised bar length isn’t the full length of the bar. It’s the cutting length, or the usable portion of the bar that guides the chain. This is the distance from the tip of the bar back to where the bar enters the chainsaw body. This is where many get confused.

• What to Measure: Measure from the very tip of the bar to the front of the chainsaw housing. This is where the chain exits the housing and starts its journey around the bar.
• Don’t Include: Do not include the portion of the bar that is inside the chainsaw housing, as this is not part of the cutting length.

I remember when I first started using chainsaws. I made the mistake of measuring the entire bar, including the part inside the saw. I ended up buying the wrong size chain, and it was a frustrating (and wasteful) experience. Learning to measure from the tip of the bar to the point where it meets the saw body saved me a lot of headaches.

Pro Tip 2: Using the Correct Tools

While you can use a standard measuring tape, I recommend using a flexible measuring tape. A flexible tape can better conform to the curve of the bar, giving you a more accurate reading.

• Tools Needed:
  • Flexible measuring tape
  • Straight edge (optional, for added accuracy)
  • Pen and paper to record the measurement
• Measuring Technique:
  1. Ensure the chainsaw is turned off and the chain brake is engaged for safety.
  2. Start the tape measure at the tip of the bar.
  3. Extend the tape measure along the top edge of the bar to the point where the bar enters the chainsaw housing.
  4. If using a straight edge, place it perpendicular to the bar at the point where it enters the housing to get a precise endpoint.
  5. Record the measurement in inches or centimeters.

Pro Tip 3: Checking the Manufacturer’s Specifications

The easiest and most reliable way to determine your chainsaw’s bar length is to check the manufacturer’s specifications. This information can usually be found in the chainsaw’s manual or on a sticker on the chainsaw itself.

• Where to Look:
  • Chainsaw Manual: The manual will have detailed specifications, including the recommended bar length.
  • Sticker on the Chainsaw: Many chainsaws have a sticker near the bar that lists the bar length.
  • Manufacturer’s Website: If you can’t find the manual or sticker, check the manufacturer’s website for the chainsaw’s model specifications.
• Cross-Referencing: Always cross-reference the manufacturer’s specifications with your physical measurement to ensure accuracy.

I once encountered a situation where the sticker on the chainsaw was damaged and unreadable. I had to go to the manufacturer’s website and download the manual to confirm the correct bar length. This simple step saved me from potentially buying the wrong parts.

Chainsaw Bar Length and Costs: A Deep Dive

Now that we know how to accurately measure the bar length, let’s explore how it impacts costs. Different bar lengths affect the type of work you can do, the power required from the chainsaw, and ultimately, the cost of maintaining and operating your saw.
