How To Measure Chainsaw Chain Length(Step By Step):

There is a wide range of sledgehammers available and when dealing with simple chainsaw maintenance, anything from how they are operated to the size needs to be taken into account. However, no matter what sort of saw you have, you’ll need to take regular care of your chain-and have it replaced over time. 

Chains often reflect these differences because of the large variations in saw sizes, and it is very important to get the correct size of the chainsaw blade. Not only do you need the right rope to run your saw, you run some serious risks in your life if you use the wrong size one. The following describes how you weigh a chainsaw chain and some useful chain care tips are also included.

You Don’t be afraid. To ascertain the replacement parts you can buy, you should weigh both your bar and your chain. Chain saws are highly useful instruments for cutting trees, pruning branches and much more, so you need to have all the right tools for them to function at their best. Other than this, it may also be risky to use your chainsaw if you use the wrong bar or an ill-fitting chain. 

In your instruction manual, you should be able to find all the figures you need, but there are a range of ways to work it out yourself if you have missed it or it is otherwise inaccessible, so here we looks at how to measure a chainsaw bar. 

You can check out this short video first, if you’d like a quick preview of what we’re going to be talked about. 

You’ve also got a rude reminder that tools work best when the measurements are correct. This applies especially to chain saws such as chainsaws. In comparison to the value of your chainsaw wheel, measuring is important. 

If you’re weighing a saw, you’re probably conscious that it’s time for a replacement. In order to keep them lasting, all chains need general maintenance (see our article: How to Sharpen a Chainsaw), but if you’ve taken good care of your saw and it’s not cutting as it should, it’s probably time for a new one. Other items to look for which suggest a substitute include: 

Used or broken teeth are 

The tension of the chain will not remain tight or is too full and will not loosen. 

Smell occurs while cutting 

Instead of wood chips, leaf mulch is left. 

Chain rattles appear unbalanced or seem to be

Why does a chainsaw lenth need to be measured?

Let’s briefly remind ourselves of why you need to do it before we talk about how to do it. Why do you need to measure a chain saw bar or chainsaw chain? 

It can last a long time if you maintain and care for them well, and this is just as true of gas-powered models of corded chainsaws and sensor chainsaws. 

Chains and bars, nevertheless, can be worn and will need to be replaced from time to time. 

It is important to choose the right bar length for your chainsaw if you want it to work effectively, and ensuring that you should have the right chain length will help you operate your equipment with the least risk of injury.

You can also decide that you want to fit your chainsaw with a larger or smaller bar, so you want to measure the price of the bar you are generally using to figure out what size to buy as a backup.

You’ll need to decide the height of your bar if you’re looking for a replacement bar for your chainsaw. 

The available length of the bar also called the cutting length or called the length, will be measured. 

In order to understand what is being addressed, you need to understand what a few simple sections of it are called before getting started on how to calculate your chain. 

The Pub 

What the chain sits upon and spins on is the bar. This is the flat metal portion that has a grooved section in which the connections of the saw drive lie. 

Links To Move 

Via drive connections that fit into the bar groove, a chain is secured to the bar. These are positioned along the bottom of the chain opposite the cutting teeth. 

Gauge Gauge 

The gauge refers to how big the ties to the drive are. This prevents the bar from falling off the chain.

Where to find measurements of the chain:

Measuring your chainsaw has little to do with the actual length of your chain, and more to do with fit and secure. A chainsaw calculation is a combined understanding of the number of the pitch gauge and drive connection and is almost always placed on the tip of your bar, saving you from wanting to do any estimate at all. 

These statistics apply to the numbers that you can see on the packaging of a new chain. But it is also important to know how these numbers are derived, particularly when these wear even a well bar sometimes or when you have extras lying along from different saws.


A easy method that does not take much time at all is testing your chainsaw for suit. To better understand how to select the right chain for your saw, just follow these fast steps. 

Phase 1: The Bar Calculation

You will calculate the so-called length to decide the height of your bar. With the bar and chain on, you do this, not off. While this is not valid for chain calculation, for bar replacement and chain size, it gives you a general number. 

Measure from the front of your saw to the farthest cutting tip to measure your bar. Round up to the nearest inch until counted. It would be the so-called duration and what producers use, for instance, when referring to an 18 chainsaw or 24 inch chainsaw.

Mearning the gauge:

It can be tricky to calculate the gauge as there are incredibly small differences between the various gauge sizes. Checking the bar or user’s manual is the best way to be sure of this scale. If you still can not find this measurement, you can take your coins (quarter, dime and penny) and slide them into the bar groove with a simple ‘trick of the trade’. Without trying to push it, you want the coin to slip in snugly. 

Penny: gauge .058. 

Dime: Gauge .050 

Quarter: gauge .063 

There is also a .043 gauge, but it is not as standard. A gauge of .050 is the most common

How to measure manullay chainsaw:

It is incredibly easy to measure a chainsaw bar and can be achieved with only a tape measure. You need to weigh the bar from the chain tip to the point where the bar reaches the body or casing of the chain saw. 

If there is no chain on the bar, to compensate, just add an additional half-inch to the measurement. 

For eg, 14.5 and 15 will both be counted as 16 as you need to round both up to 16. You could then round the measurement up to the nearest even number. This is referred to as the length or sometimes the length that can be used (since this is the part of the bar you can use for cutting).

How the chain should be measured:

For the chain, the two other measures you need to know are the pitch and the gauge. 

The distance of three rivulets (the studs holding the chain together) in the chain is the pitch. Measure the distance from the centre of the first rivulet to the centre of the third rivulet and then double it to figure out the pitch. 3/8 or 0.325 are typical chain pitches. 

The chain gauge refers to the diameter of the groove in which it rests on the bar, and you may use a special trick to check it out. Just a quarter of a penny and a dime is all you can do. 

Clean the groove out to sure that there is no dirt or gunk trapped inside and then just try to manoeuvre the coins into the gorge to see which one suits better. 

  • • The gauge is 0.063 if the quarter suits best. 
  • • The gauge is 0.0588 if the penny suits best. 
  • • The gauge is 0.050 if the dime suits best.
  • • Deciding about how long you need a bar:

Another bar measurement issue is deciding how long you need a bar-you may need to consider this when buying a fresh chainsaw or when considering buying a replacement bar. 

The usual guide is to think about the wood diameter that you need to cut most often and then add an extra two inches. For example, you will need a bar of 12 if you most often need to cut trees with a diameter of 10. This gives you enough bar to deal comfortably and with just one pass with trees of this size. 

Know, by making two passes and cutting from both sides, wood with a diameter of nearly twice the length of your bar can be cut. This is more time-consuming, however, and while it is fine from time to time, if you have to do it more often, it’s not practical. You would be better off having a longer bar in that case. 

Here’s a video about choosing the correct guide bar for your needs that goes into more detail.

Why Measuring Your Chainsaw Parts is Necessary?

Chainsaws that are badly fitted are extremely dangerous. For this reason, when it comes time to replace a section, many people have them professionally serviced. However, if you obey the above instructions, measuring your chainsaw is not difficult. 

Plus, you can ensure that you use it for acceptable tasks now that you know what size of chainsaw bar you have. 16 to 18-inch bars, for example, are suitable for light work, such as tree trimming and pruning. Meanwhile, it is possible to use 20 to 24-inch bars to drop mature trees and collect vast quantities of firewood.

Measure The Chainsaw:

The length is integrated into the model number of their chainsaws by certain producers. STIHL, for example, contains a five-digit code that corresponds to the form of the pitch, gauge cutter style cutter and any special information applicable. Companies like Dayton and Dolmar/Sachs, meanwhile, don’t tell you explicitly. Therefore, to get an accurate calculation, you must reference the owner’s manual or perform the required tasks. 

For instance, if you own a STIHL made in Germany with a chain that reads 33 RS3, you can use this marketing number to decide all of the chain’s features. The first three suggest that it has a 3/8 of an inch pitch. The second 3, meanwhile, defines the drive gauge as having a length of 1.3 millimetres. Alternatively, businesses like Husqvarna have user manuals with an online database that enables you to reference component numbers. 

When to get your bar replaced ?

For many years, bars will last. Replacing them is costly and labor intensive, so when it’s time to repair a worn or broken part, many individuals have their chains professionally serviced. It is important to remember that it is always possible to fix chains that are twisted or loose rather than replacing them. 


A Cautionary Phrase

Likewise, without the necessary knowledge, you should never operate on or try to fix a power tool. In addition, to ensure you are well-protected, you can always use protective gear, such as gloves, eye protection, and loggers. Contact the manufacturer or a local repair professional if you have any questions or concerns. 

Ultimate Thoughts 

Learning how to judge the bar is an important skill if you use a chainsaw frequently. Fortunately, this job needs to be carried out only once. Once you have that detail, you can buy replacement parts easily. With that being said, investing in a decent saw and maintaining it properly will prolong the life of your instruments and save you cash. However, if you need to procure sequence similarity, you now have the know-how to do so.


You can now calculate the size of your chain if you add the pitch and gauge, where the size of certain chain pitch plus the number of your drive links is representative of the right standard. 

You are now willing to spend your saw’s replacement bar and chain. You are now willing to spend your saw’s replacement bar and chain. You can now calculate the size of your chain if you add the pitch and gauge, where the size of your chain pitch plus the number of your drive links is representative of the length needed. 

Now you are able to buy your saw’s replacement bar and chain.
