Round the measurement up to the nearest even number if the figure was uneven or fractional. The resulting number is the bar measurement.
How do I know what size chain I need for my chainsaw?
To get the correct size, simply count 3 rivets on the chain and measure the distance between them from the centre points. Now divide this by half to get your size. As an example, three rivets that measure ½ an inch across divided by two gives you a pitch of a ¼ inch.
How do you measure a Stihl chainsaw chain?
If you are replacing a Stihl® chain, you can look at the numbers on the side of the chain to determine pitch, gauge, and other characteristics of the chain. Example: Your chain has the number 33RM2 stamped in the side of it. The last three numbers (or letters) denote characteristics of the chain.
How do I know what size chain I have?
To determine the pitch (chain size), you’ll need to measure the distance between any three consecutive rivets, then divide the result by 2. The rivets are the small, round pegs/studs that hold the chain segments together. Measure from the first to the third, then divide that number in half to get your chain pitch.
What does 72 mean on a chainsaw chain?

How long is a 16 inch chainsaw bar?
Start your tape measure on one end of the bar and extend the tape to the tip on the other side to find the true length. Round the measurement to the nearest inch to know the true length of the chainsaw bar. For example, if the measurement is 16 1⁄3 inches (41 cm), then the true length of the bar is 16 inches (41 cm).
How do I tell what grade my chain is?
So, to determine a chain grade, manufacturers must find the ultimate breaking strength. Then, divide that number by . 224805 to determine the ultimate breaking strength in newtons. Next, take that number and divide it by the total area of two cross-sections of a single link.

Are 11 and 12 speed chains the same?
This is accomplished by making the outer links of the chain thinner. Ultimately, single-speed chains are the strongest because they can be very thick since there’s only one cog at the back.
