5 Steps to Measure the Length of a Chainsaw Chain

Determining the length of a chainsaw chain is crucial for ensuring optimal performance and safety during operation. Whether you’re replacing an existing chain or installing one on a new saw, accurately measuring the length is essential to avoid improper fit or chain breakage. This article will provide you with a comprehensive guide on how to measure the length of a chainsaw chain, ensuring that you have the correct chain for your specific saw and application.

To begin the measurement process, you will need a tape measure or a ruler. Firstly, lay the chainsaw chain on a flat surface, ensuring that it is straight and not twisted or tangled. Next, locate the drive links, which are the links that engage with the sprocket on the chainsaw. These links typically have a larger hole or a different shape than the other links. Starting from the center of a drive link, count the number of drive links until you reach the center of the next drive link. The resulting count represents half the length of the chain.

Once you have obtained the half-length, multiply it by two to determine the total length of the chain. For instance, if you counted 15 drive links, the chain’s length would be 15 multiplied by 2, which is 30 links. It’s important to note that the length of a chainsaw chain is often expressed in terms of the number of drive links, rather than the total number of links. Therefore, when purchasing a new chain, ensure that you specify the number of drive links that match your saw’s requirements.

Determining the Chain Length by Measuring the Chain Links

Measuring the chain links is the most straightforward method to determine the length of a chainsaw chain. To do this, follow these detailed steps:

**Materials Required:**

Measuring tape or ruler

Steps:

Count the Number of Drive Links:
- Locate the drive links, which are the largest and most prominent links on the chain.
- Start counting the drive links from the first link that is connected to the guide bar.
- Count all the drive links on the chain, excluding any that may be damaged or missing.
Measure the Length of a Single Drive Link:
- Take a measuring tape or ruler and align it with the center of a drive link.
- Measure the distance between the center points of the two adjacent drive links.
- Record this measurement as the length of a single drive link.

Calculate the Total Chain Length:

Multiply the number of drive links by the length of a single drive link.
The result is the total length of the chainsaw chain.

To summarize, measuring the chain links involves counting the drive links, measuring the length of a single drive link, and multiplying these values to obtain the total chain length. This method provides an accurate and reliable way to determine the chain’s length.

Using a Measurement Tool to Gauge Chain Length

Employing a Tape Measure or Ruler

A straightforward and accurate method for determining chain length is to use a tape measure or ruler. Begin by laying the chain flat on a stable surface. Ensure that the chain is straight and free from kinks or tangles. Then, align the starting point of the measurement tool with one end of the chain. Carefully measure along the chain, following its contours, until you reach the other end. Record this measurement as the chain length.

Utilizing a Chain Gauge or Calibrator

Chain gauges or calibrators are specialized tools designed specifically for measuring chainsaw chains. They typically consist of a series of slots or holes corresponding to different chain sizes. To use a chain gauge, insert the end of the chain into the appropriate slot or hole. If the chain fits snugly without excess play, that is the correct length for your chainsaw. Chain gauges are a convenient and precise method for determining chain length, ensuring an accurate fit and optimal performance.

Measurement Tool	Accuracy	Convenience
Tape Measure or Ruler	High	Moderate
Chain Gauge or Calibrator	Very High	Very High

Identifying the Pitch and Gauge to Calculate Length

To determine the length of a chainsaw chain, you need to identify its pitch and gauge. Pitch refers to the spacing between the drive links on the chain, while gauge indicates the thickness of the drive links.

Measuring Pitch

To measure pitch, count the number of drive links (excluding the cutter teeth) within a 6-inch (15-centimeter) segment of the chain. Then divide the count by 2. The result will be the pitch in inches.

Measuring Gauge

To measure gauge, use a caliper to determine the thickness of the drive links. Specifically, measure the distance between the two inner surfaces of the drive links. The result will be the gauge in inches.

Calculating Length using Pitch and Gauge

Once you have identified the pitch and gauge, you can calculate the length of the chain using the following formula:

Length = (Number of Drive Links + 1) x Pitch

The “+ 1” in the formula accounts for the cutter tooth that is not included in the drive link count. It is important to align the chain correctly on the bar before counting the drive links to ensure accuracy.

Example
If a chain has a pitch of 0.375 inches and a gauge of 0.063 inches, and there are 50 drive links, the length can be calculated as: Length = (50 + 1) x 0.375 = 18.75 inches

Counting the Drive Links

The drive links are the links that engage with the sprocket on the chainsaw bar. To count the drive links, hold the chain up to the bar and align the first drive link with the sprocket. Count the number of drive links until you reach the end of the chain.

If the chain has an odd number of drive links, add one to the count to get the total number of links in the chain. For example, if you count 31 drive links, the total number of links in the chain is 32.

If the chain has an even number of drive links, the total number of links in the chain is the same as the number of drive links. For example, if you count 32 drive links, the total number of links in the chain is also 32.

Here is a table summarizing the steps for counting the drive links on a chainsaw chain:

Step	Description
1	Hold the chain up to the bar and align the first drive link with the sprocket.
2	Count the number of drive links until you reach the end of the chain.
3	If the chain has an odd number of drive links, add one to the count to get the total number of links in the chain.
4	If the chain has an even number of drive links, the total number of links in the chain is the same as the number of drive links.

Utilizing a Template or Chain Size Chart

Measuring Using a Template

Obtain a chainsaw chain template or purchase from reputable retailers. Template usually displays multiple chain sizes for convenient matching. Align the template’s notches with the drive links on your chain Begin at the chain’s tip and slide the template towards the opposite end. Count the number of notches that match up to determine the chain’s length.

Determining Chain Size

Consult chainsaw manufacturer’s website or user manual locate size charts. Enter your chainsaw model number into the search bar and access the machine’s specifications. Look for the “chain size” or “chain pitch” section. The chart will provide a list of compatible chain lengths for your chainsaw model.

Referencing the Drive Link Count

Count the number of drive links on your chain. Drive links are the rectangular-shaped links that engage with the sprocket on your chainsaw. Count all the drive links, including any half-links. Multiply the number of drive links by the chain’s pitch to determine the length of the chain.

For example, if you have a chain with 68 drive links and a pitch of 0.325 inches:

“`
Chain Length = Number of Drive Links × Pitch
Chain Length = 68 × 0.325 inches
Chain Length = 22.1 inches
“`

Additional Notes

It’s important to select the correct chain length for your chainsaw. Using an incorrect length can damage the saw and pose a safety hazard. If you’re not comfortable measuring the chain yourself, consult a professional for assistance.

Measuring the Circumference of the Loop

Determine the Number of Drive Links

Count the number of individual links in the loop, excluding any master links (joined links). Drive links are the links with teeth or cutters.

Subtract One for the Overlap

In a continuous loop, there is an overlap of one drive link at the connection point. Therefore, subtract one from the total number of drive links counted.

Multiply by the Drive Link Pitch

The drive link pitch is the distance between the centers of two adjacent drive links. It is typically measured in inches or millimeters. Multiply the number of drive links (minus one) by the drive link pitch to obtain the pitch circumference of the loop.

For example, if you have a loop with 82 drive links and a drive link pitch of 0.325 inches, the pitch circumference would be calculated as follows:

“`
Pitch Circumference = (82 – 1) x 0.325 inches = 26.5 inches
“`

Consider the Master Link

If the loop contains a master link, add its thickness to the pitch circumference value obtained in the previous step. The master link thickness varies depending on the chain type and manufacturer, but it is typically around 0.25 inches to 0.5 inches.

“`
Example:

If the master link thickness is 0.4 inches, the total circumference of the loop would be:

Total Circumference = Pitch Circumference + Master Link Thickness
= 26.5 inches + 0.4 inches = 26.9 inches
“`

Alternative Method: Measure Around the Loop

If measuring the circumference of the loop directly, use a flexible measuring tape or cord. Wrap the measuring device around the loop, ensuring that it follows the inner edges of the drive links. Record the length indicated on the measuring device. This method may be slightly less accurate than the pitch circumference calculation but is more straightforward and suitable for non-standard or broken loops.

Estimating Chain Length Based on Saw Bar Size

If you already have a saw bar, you can estimate the chain length needed by measuring the bar’s length and referring to the table below. Note that this is just an approximation, and the actual chain length may vary slightly depending on the specific chainsaw model and chain type.

Saw Bar Length (inches)	Chain Length (links)
10	34-36
12	38-40
14	42-44
16	46-48
18	50-52
20	54-56

For example, if your saw bar measures 16 inches, you would likely need a chain with 46-48 links.

Referencing the Chainsaw Manufacturer’s Specifications

The chainsaw manufacturer’s specifications should be your primary source of information for determining the length of your chainsaw chain. The user manual or product listing will typically specify the recommended chain length for your specific model.

Chain Length Notation

Chain length is typically denoted as a number followed by a letter, such as “18in” or “20in.” This number represents the cutting length of the chain, which is the length of the portion of the chain that extends beyond the guide bar.

Drive Link Length

In addition to the overall chain length, you should also consider the drive link length. This is the distance between the centers of three consecutive drive links (rivets) and is measured in inches or millimeters.

Measuring Chain Length with a Measuring Tape

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

Lay the chain out on a flat surface.
Measure the distance from the center of the first drive link (rivet) to the center of the last drive link.
Divide the result by 2 to get the cutting length of the chain.

Chain Length Notation	Cutting Length	Drive Link Length
16in	16 inches	0.325 inches
18in	18 inches	0.325 inches
20in	20 inches	0.375 inches

Incorporating an Error Margin for Accurate Measurements

When measuring the length of a chainsaw chain, it’s important to account for potential errors to ensure accurate measurements. Incorporating an error margin provides a buffer around the measured value, increasing the reliability of the results.

Estimating the Error Margin

The error margin should be based on the level of precision required and the measurement tools used. Consider the following guidelines:

For rough estimates, a 5% error margin is typically sufficient.
For more precise measurements, reduce the error margin to 2-3%.
If using a measuring tape, account for the tape’s graduations and the user’s ability to read them accurately.

Error Margin	Precision Level
5%	Rough Estimates
2-3%	Precise Measurements

Applying the Error Margin

Once the error margin is determined, it should be applied to both the measured length and the desired length. For example, if the measured length is 18 inches and the desired length is 20 inches with a 5% error margin, the acceptable range becomes:

(18 – 0.05 * 18, 18 + 0.05 * 18) = (17.1, 18.9)

This means that the chainsaw chain is within the desired length range, considering the error margin.

How To Measure The Length Of A Chainsaw Chain

Measuring the length of a chainsaw chain is a simple task that can be done in a few minutes with a few simple tools. The most common method is to use a tape measure to measure the length of the chain from one end to the other. However, you can also use a chain gauge, which is a specialized tool designed to measure the length of chainsaw chains. Another method is to count the number of drive links in the chain. A drive link is the link that fits into the guide bar, and it usually has a large, round head. To count the number of drive links, simply start at one end of the chain and count each link until you reach the other end.

Once you have measured the length of the chain, you can find the correct replacement chain by matching the length of the chain to the model of your chainsaw. You can find the model number of your chainsaw on the body of the saw.
