How to Determine the Right Replacement Chainsaw Chain Size


Determining the right chainsaw chain size can be confusing for anyone who does not use chainsaws on a regular basis.  If you are not a chainsaw expert and need to replace your chainsaw chain, this how-to guide should tell you everything you need to know to ensure the replacement chainsaw chain you purchase will fit and work with your chainsaw.

We sell bulk chainsaw chain and chainsaw chains ready to fit the most common chainsaw bar sizes such as 14", 16", 18", 20", and 22".

3 Measurements To Buy The Right Chain For Your Saw

The 3 things you need to know about the chain your chainsaw accepts is the pitch, gauge, and number of drive links.

Let's learn what each of these chainsaw chain characteristics are.

Chainsaw Chain Size Formula

(Pitch + Gauge) + Number of Drive Links = Chainsaw Chain Size/Length

Chainsaw chain parts

Chainsaw Chain Pitch

The pitch of a chainsaw chain refers to the distance between the drive lugs.  Drive lugs are also called drive links.  An easy reference for measuring pitch is every 3 rivets.  Divide the distance between 3 rivets by 2 to get the pitch.

Pitch determines if the chain will fit the chainsaw's sprocket.

Most chains saws use 0.325", 3/8", or 0.404" pitch, with 1/4" being a less common size that is also used on some saws.  1/2" pitch can be found on some older saws.

Most consumer chainsaws use low profile chains which is a special version of a 3/8" pitch.  Stihl and other brands refer to low profile as Picco.

Measure chainsaw chain guage

Chainsaw Chain Gauge

The gauge of a chainsaw chain is the thickness, or width, of the drive lugs.

Most chainsaws use 0.050" (1.3 mm) and 0.058" (1.5 mm) gauge chains.  0.043" (1.1 mm) and 0.063" (1.6mm) gauge chains are less common.

Number of Chainsaw Chain Drive Links

The number of drive links can be determined by counting the drive links on the chain you are replacing.

Can Your Chainsaw Chain Be Sharpened?

Chainsaw chains can be sharpened.  It is important to sharpen your chainsaw chain correctly to ensure it does not fail during use and cuts effectively after sharpening.

Chainsaw chain cutter life cycle as it gets sharpened

The image above depicts the shapes throughout the life cycle of a chainsaw cutting tooth.  It is important to remove all of the material as shown while sharpening.  A common mistake is to solely sharpen the very top of the cutter.

Stihl Chainsaw Chain Replacement Guide

If you are replacing a Stihl® chainsaw chain, you can reference the numbers on the side of the chain.  These numbers determine the pitch, gauge, and other characteristics of the chain.  Stihl® refers to these numbers as their Marketing Number System.

Stihl® Marketing Number System Example:

33RS3 - Your Stihl® chain has the number 33RS3 stamped in the side of it.

Stihl Marketing Number System

Pitch

Distance between three rivets divided by 2 as shown.

1 = 1/4"

2 = .325"

3 = 3/8"

4 = .404"

= Stihl Picco (3/8" Extended)

6 = Stihl Picco (1/4" Extended)

Chainsaw Chain Gauge Reference Chart

Gauge

Marked on the drive link as shown.

3 = .050" (1.3 mm)

5 = .058" (1.5 mm)

6 = .063" (1.6 mm)

0 = .080" (2.0 mm)

Chainsaw Bar and Chain Size Chart

Chains, bars, and sprockets can easily be replaced by the chainsaw's owner, dealer, or small engine repair shop.  Please consider the size of chain on the saw now may not be the size chain that was on the saw when it was manufactured

This chart can help you find a chain for your saw, but you should determine the size of your existing chain and the number of drive links before making a purchase.  The information provided in this chart is believed to be true but we request you to verify the size requirement of your saw before making a purchase.
