Chainsaw chains are an essential part of the tool, and they need to be the right length to work properly. If the chain is too short, it will not be able to cut effectively. If the chain is too long, it will be more likely to derail.

Measuring the length of a chainsaw chain is a quick and easy process. There are two main methods: using a tape measure or using a chain gauge.

Using a Tape Measure

To measure the length of a chainsaw chain using a tape measure, follow these steps:

Lay the chainsaw chain out on a flat surface.
Stretch the chain out so that it is as straight as possible.
Measure the distance from one end of the chain to the other.
Double the measurement to get the total length of the chain.

Using a Chain Gauge

A chain gauge is a specialized tool that is used to measure the length of chainsaw chains. Chain gauges are available in a variety of sizes, so make sure to choose one that is the right size for your chain.

To measure the length of a chainsaw chain using a chain gauge, follow these steps:

Place the chain gauge over the chain.
Align the gauge with the teeth on the chain.
Read the measurement on the gauge.
Double the measurement to get the total length of the chain.

Determining the Pitch of Your Saw Chain

The pitch of a saw chain refers to the distance between the drive links, which are the links that engage with the drive sprocket on the saw. The pitch is typically measured in inches, and the most common pitches for chainsaws are 0.325″, 0.375″, and 0.404″.

To determine the pitch of your saw chain, you can use a pitch gauge or a measuring tape. If you are using a pitch gauge, simply place the gauge over the drive links and read the measurement. If you are using a measuring tape, measure the distance between three consecutive drive links and divide by 2. The result will be the pitch of your saw chain.

Here is a table summarizing the steps for determining the pitch of your saw chain:

Step	Action
1	Clean the saw chain to remove any dirt or debris.
2	Locate the drive links on the saw chain. These are the links that have a round or oval opening in the center.
3	If using a pitch gauge, place the gauge over the drive links and read the measurement. If using a measuring tape, measure the distance between three consecutive drive links and divide by 2.
4	The result will be the pitch of your saw chain.

Identifying the Gauge of Your Saw Chain

To measure the length of a chainsaw chain accurately, you must first identify the gauge of your saw chain. The gauge refers to the thickness of the drive links, which are the links that engage with the chainsaw’s sprocket. It is typically measured in inches or millimeters, and it can vary between different chainsaws and chain models.

There are three common chain gauges: 0.050″, 0.058″, and 0.063″. To determine the gauge of your chain, you can measure the thickness of the drive links using a caliper or a ruler. You can also refer to the manufacturer’s specifications for your chainsaw or chain.

Once you have identified the gauge of your chain, you can use the appropriate method to measure its length, as described in the following sections.

Gauge	Description
0.050″	Commonly used on smaller chainsaws for homeowner use
0.058″	Suitable for mid-sized chainsaws used for both homeowner and professional applications
0.063″	Designed for larger, more powerful chainsaws used in commercial and professional settings

Measuring the Length of the Chain with a Ruler

Using a ruler is a straightforward method to measure the length of a chainsaw chain. Follow these steps to obtain an accurate measurement:

Place the chain on a flat surface, making sure it is not twisted or tangled.
Align the zero mark of the ruler with the first drive link of the chain.
Count the number of drive links along the length of the chain. Drive links are the larger, alternating links that engage with the guide bar. Typically, there are 25, 30, or 35 drive links per inch of chain.
Multiply the number of drive links by the pitch to determine the overall length of the chain.

Drive Link Count	Pitch	Chain Length
25	0.325″	8″
30	0.375″	11.25″
35	0.404″	14″

Using a Measuring Tape to Determine Chain Length

Place the measuring tape against the drive link or a cutter joint. As you measure along the chain, make sure the tape stays perfectly straight, or else you will get an incorrect reading.

When measuring along the chain, skip every third cutter link. This is because the cutting chain teeth repeat in a three-link cycle, and measuring three cutter links will give you the correct distance of two cutter links.

Stop measuring when you have counted all the cutter links and reached the last drive link. Record the measurement, which will be the total length of the chain.

For example, if you counted 21 cutter links, the overall length of the chain will be 42 links (21 x 2 = 42).

Tips for Accurate Measurement:

Use a high-quality measuring tape that is not stretched or damaged.
Hold the tape taut while measuring, but not so tightly that it bends the chain.
Make sure the drive links or cutter joints are aligned correctly with the zero mark on the tape measure.
If you are measuring a chain that has already been used, clean it first to remove any debris that could affect the measurement.

Verifying the Chain’s Correct Length for Your Saw

Once you have determined the correct pitch and gauge for your chainsaw, you need to verify that the chain you have is the correct length. Chains that are too short or too long can damage your saw and pose safety hazards.

To determine the correct length of the chain, refer to your chainsaw’s manual or contact the manufacturer. The manual will specify the recommended chain length for your model.

Here are the steps on how to verify the chain’s correct length:

Unplug your chainsaw and put on safety gear, including gloves and eye protection.
Remove the guide bar from the saw.
Lay out the chain in a straight line, with the drive links facing upwards.
Measure the distance between the first and last drive links, excluding the tail or connecting link.
Compare this measurement to the recommended chain length for your chainsaw. If the chain is too short or too long, you will need to adjust it or replace it.

Chain Length Issues	Consequences
Too Short Chain	Poor cutting performance, increased chain wear, damage to guide bar
Too Long Chain	Excessive vibration, safety hazard, damage to saw components

Measuring the Length of a Chainsaw Chain

Accurately measuring the length of a chainsaw chain ensures optimal performance and safety. Follow these steps for precise measurement:

Unplug the chainsaw and wear appropriate safety gear.
Remove the chain from the guide bar.
Count the number of drive links (sharp, tooth-shaped links that engage the guide bar).
Determine the pitch of the chain by measuring the distance between three consecutive rivets (the small, connecting pins between the links). Common pitch sizes include 0.325″, 0.375″, or 0.404″.
Multiply the number of drive links by the pitch to calculate the chain length. For example, a chain with 72 drive links and a 0.375″ pitch would have a length of 72 x 0.375 = 27 inches.

Adjusting the Tension of Your Chain for Optimal Performance

Proper chain tension is crucial for safe and efficient chainsaw operation. Here’s how to adjust the tension correctly:

Check the Tension Regularly

Inspect the chain tension before each use by pulling it away from the bar about 1 inch. It should sag slightly, with enough slack to prevent binding but not so loose that it flaps or comes off.

Adjust the Tension

If the chain is too loose, turn the adjustment screw clockwise using a wrench. If it’s too tight, turn it counterclockwise. Tighten the screw until the chain has the desired tension.

Check the Tension Again

Once the screw is tightened, recheck the tension by pulling the chain away from the bar. If necessary, make further adjustments until the tension is correct.

Lubricate the Chain

After adjusting the tension, lubricate the chain with bar oil to ensure smooth operation. This will reduce friction and prolong the life of the chain and bar.

Table of Recommended Tension

Chain Type	Tension
Hobby Chains	1/2″ to 1″ sag
Professional Chains	3/4″ to 1-1/4″ sag

The Formula for Measuring Chainsaw Chain Length

The formula for determining the length of a chainsaw chain is as follows:

For Loop Chains:	Number of Drive Links x 2
For Non-Loop Chains:	Number of Drive Links + 1

Troubleshooting Issues Related to Chain Length

Chain Too Long

A chain that is too long can:

Slip off the sprocket
Get caught in obstacles
Cause premature wear on the chain and sprocket

To fix a chain that is too long, remove a few drive links.

Chain Too Short

A chain that is too short can:

Bind up on the bar
Reduce cutting efficiency
Cause the saw to overheat

To fix a chain that is too short, add a few drive links.

Wear on Drive Links and Drive Sprocket

As the drive links and drive sprocket wear, the chain will stretch. This can cause the chain to become too loose, which can lead to the problems described above. To prevent this, inspect the drive links and drive sprocket regularly for signs of wear. If either component shows signs of wear, replace it.

Inconsistent Cutting Depth

If the chain is not the correct length, it can cause inconsistent cutting depth. This is because the chain will not be able to maintain the correct tension, which will affect the saw’s ability to cut through wood.

Premature Chain Failure

A chain that is too long or too short can experience premature failure. This is because the chain will be subjected to excessive stress, which can cause it to break.

Kickback

A chain that is too long can also increase the risk of kickback. This is because the longer chain will have more momentum, which can cause the saw to kick back if it gets pinched or caught in wood.

Measuring the Length of a Chainsaw Chain

To measure the length of your chainsaw chain, follow these steps:

Place the chain on a flat surface, with the cutting teeth facing up.
Measure the distance from the top of one cutting tooth to the top of the next cutting tooth.
Multiply the distance by the number of cutting teeth on the chain.
The result is the length of the chain in inches.

Maintaining the Sharpness of Your Saw Chain

A sharp chainsaw chain makes cutting easier and more efficient, and it also helps to reduce the risk of kickback. Here are some tips for maintaining the sharpness of your saw chain:

File your chain regularly. The frequency of filing will depend on the type of wood you are cutting and how often you use your chainsaw.
Use the correct file size. The file size should be matched to the size of the cutting teeth on your chain.
File at the correct angle. The filing angle should be 30 degrees for most chainsaws.
Keep your files sharp. Dull files can damage your chain.
Clean your chain regularly. Sap and other debris can build up on your chain, which can make it dull.
Lubricate your chain regularly. Lubrication helps to keep your chain sharp and free of corrosion.
Avoid cutting into dirt or rocks. Dirt and rocks can dull your chain quickly.
Check the chain tension regularly. Proper chain tension helps to maintain sharpness and prevent damage. Check the tension by picking up the saw by the tip of the guide bar and pulling the chain upward. It should move about 1/8″ to 1/4″.

By following these tips, you can keep your chainsaw chain sharp and help it to last longer.

Here is a table that summarizes the steps for measuring the length of a chainsaw chain:

Step	Description
1	Place the chain on a flat surface, with the cutting teeth facing up.
2	Measure the distance from the top of one cutting tooth to the top of the next cutting tooth.
3	Multiply the distance by the number of cutting teeth on the chain.
4	The result is the length of the chain in inches.
