Chain pitch is the spacing of the chain drive links, and it is measured in in. Your saw, bar, and sprocket decide the right value together. The first thing to check is the pitch already written on your current chain or in the saw’s manual.
Which chain pitch fits your situation?
| if this is you | the chain pitch that suits you | why |
|---|---|---|
| You are replacing the chain on a saw that still runs well. | The pitch already stated on the chain. | The bar groove and sprocket were built around that spacing. |
| You can read the old chain, but the manual is missing. | The same pitch printed on the drive links. | That marking is the fastest way to confirm the fit. |
| You are matching a new chain to a known bar and sprocket set. | The pitch specified for that bar and sprocket. | The chain must match the hardware that drives it. |
| You are buying a replacement because the old chain wore out early. | The exact pitch the saw already uses. | A different spacing can cut poorly or not fit at all. |
| You only know the saw is an older model. | The pitch from the parts list or owner’s manual. | Older saws often use a fixed setup, and guessing invites a mismatch. |

To ensure proper fitment, learn how to choose the correct chain gauge for chainsaws.
How do you find your own chain pitch before ordering?
Use the chain itself first. Many chains have the pitch stamped on the drive links, and the owner’s manual or parts diagram usually repeats it.
The easiest way to think about it is like a key cut for one lock. A chain with the wrong spacing may still look close, but the fit is not close enough for the bar and sprocket.
New users should first learn about the different types of chainsaws.
For a reader upgrading an older saw, this step saves the return or the time lost to a second order. If you cannot confirm the pitch from the chain or paperwork, confirm the current rules for your location before ordering any saw-related item that may be restricted where you live.
That spread is a reminder that the number is a fit detail, not a quality score.
Start with the basics by viewing how a chainsaw works and functions.
What happens when chain pitch is too small or too large?
A wrong pitch shows up as a fit problem first, not as a vague performance issue. If the spacing is too small or too large for the bar and sprocket, the chain will not sit correctly on the drive system.
How the wrong chain pitch affects chainsaw performance
Too small a pitch can leave the chain loose in the wrong places or unable to engage the drive parts properly. Too large a pitch can stop the chain from matching the bar groove and sprocket teeth at all. In either case, the saw may cut badly, wear parts fast, or refuse to run as intended.
Budgeting is key, so see what different price levels get you.
The mistake costs time and a replacement chain, and it can also mean a second order for the correct size. That is why chain pitch matters before the saw ever reaches wood.
What should you do when you are between two chain pitches?
When you are between two chain pitches, do not split the difference. The correct choice is the pitch that matches the bar, sprocket, and the chain already specified for the saw.
You can see the technical breakdown in our full review of the DCCS620B.
If the marking is unclear, check the manual, the parts diagram, or the dealer listing for the exact saw setup. The pitch is not a preference item, so a halfway choice does not solve the fit problem.
If your old chain is still on the saw, remove it only long enough to read the stamped value and then match that number exactly. If the old chain is missing, use the saw’s parts information instead of guessing from bar length or chain appearance.

Most buyers who fall between two values are not facing a real choice. They are facing missing information, and the answer is to recover the original spec before ordering.
