Before you purchase a new chainsaw bar, it is important to know how to measure your existing bar. This will ensure that you get the right size bar for your saw. There are a few different ways to measure a chainsaw bar. One way is to use a tape measure. To do this, simply place the tape measure at the end of the bar and measure to the other end. Be sure to include the length of the bar that is inserted into the saw.

Another way to measure a chainsaw bar is to use a ruler. To do this, simply place the ruler at the end of the bar and measure to the other end. Again, be sure to include the length of the bar that is inserted into the saw. If you do not have a tape measure or a ruler, you can also use a piece of string. To do this, simply wrap the string around the bar and then measure the length of the string.

Once you have measured the length of your chainsaw bar, you can then purchase a new bar of the same length. It is important to note that chainsaw bars are available in different lengths. The length of the bar that you need will depend on the size of your saw and the type of cutting that you will be doing. If you are not sure what size bar you need, you can consult your saw’s manual or ask a salesperson at your local hardware store.

Determining the Correct Length for Your Chainsaw Bar

The length of the chainsaw bar you need depends on several factors, including the size of the trees you will be cutting, the type of wood you will be cutting, and the power of your chainsaw.

Here are a few things to consider when determining the correct length for your chainsaw bar:

**The size of the trees you will be cutting.** The longer the bar, the larger the trees you can cut. However, a longer bar can also make the chainsaw more difficult to handle. If you will be cutting mostly small trees, a shorter bar will be sufficient.
**The type of wood you will be cutting.** Hardwood requires a shorter bar than softwood. This is because hardwood is denser and more difficult to cut.

**The power of your chainsaw.** A more powerful chainsaw can handle a longer bar. If you have a less powerful chainsaw, you will need a shorter bar.

As a general rule, the length of the bar should be about 1.5 times the diameter of the largest tree you will be cutting. For example, if you will be cutting trees that are up to 12 inches in diameter, you would need a bar that is at least 18 inches long.

If you are not sure what size bar you need, it is always best to consult with a professional. They can help you determine the correct length for your chainsaw based on your specific needs.

Bar Length Guidelines

Chainsaw Power	Recommended Bar Length
Electric (up to 16 inches)	12-14 inches
Electric (16-20 inches)	16-18 inches
Gas (up to 20 inches)	16-20 inches
Gas (20-24 inches)	20-24 inches
Gas (24 inches and up)	24-36 inches

Measuring from the Tip to the Nose

This method involves measuring the distance from the tip of the bar – the pointed end that enters the wood first – to the nose, which is the blunt end that connects to the chainsaw body.

Here are the steps to measure a chainsaw bar from the tip to the nose:

Place the chainsaw on a flat surface with the bar facing up.
Locate the tip of the bar, which is the pointed end.
Position the end of a measuring tape or ruler at the tip.
Extend the tape or ruler along the top of the bar to the nose.
Read the measurement at the nose, which is the length of the bar from the tip to the nose.

Tips:

Ensure the chainsaw is turned off and disconnected from the power source before measuring.
Use a measuring tape or ruler that is long enough to reach from the tip to the nose.
If the bar has a protective cover, remove it before measuring.
For more precise measurements, consider using a digital caliper or measuring gauge.

Measurement Conversion Table:

Unit	Conversion
Inches	1 inch = 2.54 centimeters
Centimeters	1 centimeter = 0.3937 inches

Understanding Bar Length and Performance

The length of a chainsaw bar, measured in inches, determines the size and type of trees it can cut. A longer bar allows you to cut through thicker logs, but it also adds weight and makes the chainsaw more difficult to maneuver. The recommended bar length for your chainsaw depends on the size of the trees you typically cut.

The table below provides a general guideline for selecting the appropriate bar length:

Tree Diameter (inches)	Recommended Bar Length (inches)
6-12	12-16
13-18	16-18
19-24	18-20
25+	20+

Keep in mind that these are just general guidelines. The actual bar length you choose may vary depending on the specific model of chainsaw you have and the types of trees you cut.

Measuring the Cutting Length Only

Measuring the cutting length of a chainsaw bar is straightforward and can be done in a few simple steps. Here’s how:

Place the chainsaw on a flat surface: Ensure the chainsaw is stable and will not move during measurement.
Locate the cutting bar: The cutting bar is the long, flat metal part of the chainsaw that houses the chain.
Measure the distance from the tip to the base: Using a tape measure, measure the length of the cutting bar from the tip (where the chain starts) to the base (where the chain ends).
Note the measurement: Record the length in inches or centimeters as the cutting length of the chainsaw bar.

Additional Tips for Accurate Measurement:

Tip	Description
Use a metric tape measure for precise measurements	Metric measurements (centimeters or millimeters) provide greater accuracy.
Be aware of attachments	If there are any attachments on the bar (e.g., a guide bar), remove them before measuring.
Measure multiple times	Repeat the measurement a few times to ensure accuracy and minimize errors.

Factors Influencing Bar Length Selection

When choosing a chainsaw bar, several factors need to be considered, including:

Chain Saw Type and Use

The type of chainsaw and its intended use significantly impacts the appropriate bar length. Smaller chainsaws are typically paired with shorter bars, while larger chainsaws are compatible with longer bars for heavier-duty tasks.

Tree Size and Felling Conditions

The size of the trees being cut and the felling conditions also influence bar length selection. Longer bars are preferred for felling larger trees, while shorter bars provide greater maneuverability in tight spaces and during limbing operations.

Power of the Chainsaw

The power of the chainsaw is another crucial factor to consider. More powerful chainsaws can handle longer bars, enabling efficient cutting of thicker materials. However, pairing a less powerful chainsaw with a bar that is too long can lead to reduced performance and increased strain on the saw.

Safety Considerations

Safety is paramount when using chainsaws. Choosing a bar length that is appropriate for the operator’s height and physical abilities is essential. Additionally, the recommended bar length for a specific chainsaw should not be exceeded to avoid potential safety hazards.

Cut Capacity

Cut capacity refers to the maximum diameter of logs that a chainsaw can cut through. The cut capacity is directly related to the bar length. Longer bars have greater cut capacities, allowing for efficient cutting of larger logs. However, it is important to note that using a bar that is too long for the available power can lead to binding or stalling of the saw.

Bar Length	Cut Capacity
14-16 inches	Logs up to 12 inches
18-20 inches	Logs up to 16 inches
22-24 inches	Logs up to 20 inches
26-28 inches	Logs up to 24 inches
30+ inches	Logs over 24 inches

Measuring a Bar with a Scabbard or Case

If your chainsaw bar is in a scabbard or case, you will need to remove it to measure it. Be sure to do this in a safe and secure area.

Safety Precautions:

Wear appropriate safety gear, including gloves and eye protection.
Ensure that the chainsaw is turned off and the spark plug is disconnected.
Place the chainsaw on a stable surface.
Remove the scabbard or case from the chainsaw.
Inspect the bar and chain for any damage. If you find any damage, do not use the chainsaw.

Measuring the Bar:

Hold the bar vertically on a flat surface, with the nose of the bar facing up.
Use a tape measure to measure the distance from the tip of the nose to the bottom of the groove where the chain fits. This is the bar length.
Note the bar length and chain pitch (e.g., 18 inches, 0.325 inch pitch).
Record the measurements for future reference.

Using a Measuring Tape

Step 1: Measure the overall length of the bar, including the nose. Place the measuring tape at the base of the nose, where it meets the body of the bar, and extend it to the tip of the nose. The measurement you get is the overall length of the bar.

Step 2: Measure the length of the cutting area. Start the measuring tape from the same point at the base of the nose and extend it to the end of the cutting teeth. This measurement represents the length of the cutting area, which is also known as the effective cutting length.

Step 3: Measure the width of the bar. Measure the width of the bar at its widest point, which is typically in the middle of the bar. This measurement gives you an idea of the thickness of the bar and its suitability for different cutting tasks.

Using Calipers

Step 1: Position the calipers on the bar. Open the jaws of the calipers and place them over the bar, aligning the points of the jaws with the base of the nose and the tip of the nose.

Step 2: Close the jaws of the calipers. Gently close the jaws of the calipers until they lightly grip the bar. Ensure that the jaws are parallel to the bar and that they do not touch the cutting teeth.

Step 3: Read the measurement on the calipers. The measurement displayed on the calipers is the overall length of the bar, including the nose. It is important to note that calipers do not measure the length of the cutting area or the width of the bar.

Verifying Bar Length Specifications

Once you know the approximate length of the chainsaw bar, you can verify the exact specification by following these steps:

1. Refer to the chainsaw’s owner’s manual. The manual will typically list the bar length as part of the chainsaw’s specifications.

2. Measure the bar from the tip to the base. Use a measuring tape or ruler to measure the length of the bar from the tip of the nose to the base where it attaches to the chainsaw body.

3. Subtract the length of the chainsaw’s nose. The nose of the chainsaw is the curved end of the bar. Measure the length of the nose from the tip to the point where it meets the rest of the bar. Subtract this value from the total length to get the actual bar length.

4. Compare your measurements to the manufacturer’s specifications. The measured length should be within a few millimeters of the specified length. If there is a significant difference, consult the manufacturer or a qualified chainsaw technician.

5. Check the bar’s marking. Many chainsaw bars have a marking indicating the bar length. This marking is usually located on the underside of the bar near the base. Verify that the marking matches your measurements.

6. Consider the bar’s wear. If the bar has been used extensively, it may have worn down slightly. This can result in a shorter actual length than the specified length. Factor in the amount of wear when determining the appropriate replacement bar.

7. Use a digital caliper for precision. For the most accurate results, use a digital caliper to measure the bar length. Calipers provide precise measurements down to hundredths of an inch.

8. Consult a professional if necessary. If you are unsure about the bar length or have any other questions about your chainsaw, consult a qualified chainsaw technician. They can help you verify the bar length and ensure that your chainsaw is in optimal condition.

Measuring a Bar with Irregular Ends

Determining the length of a chainsaw bar with irregular ends (e.g., broken or damaged) requires a slightly different approach.

Steps:

Extend the Bar: If possible, extend the bar to its maximum length, fitting a broken section (if available) to estimate the overall length.
Mark the Cutting Ends: Using a tape measure or marking tool, mark the points where the irregular ends of the bar would meet if the bar were whole.
Measure the Length: Measure the distance between the two marks made in step 2. This provides the effective cutting length of the bar.
Add the Nose Length: For bars with a nose that extends beyond the cutting teeth, add the length of the nose to the measurement obtained in step 3.
Subtract the Tail Length: If there is a tail on the bar that is not used for cutting, subtract its length from the measurement obtained in step 4.
Round Up: Round the final measurement up to the nearest inch or millimeter to ensure accuracy.
Check for Irregularities: Inspect the irregular ends for any significant wear or damage that could affect the cutting performance. Consider replacing the bar if the damage is severe.
Consider the Drive Link Count: If you are purchasing a new chain to replace the one on the bar, ensure that the drive link count matches the length of the bar you measured.
Use a Conversion Chart: Refer to a conversion chart to determine the appropriate bar length for your specific chainsaw model.

Measurement	Method
Effective Cutting Length	Mark and measure the points where irregular ends would meet if the bar were whole
Nose Length	Measure the length of the nose (if any) and add it to the effective cutting length
Tail Length	Subtract the length of the tail (if any) from the effective cutting length

Ensuring an Accurate Bar Measurement

To ensure the most accurate measurement of your chainsaw bar, follow these additional tips:

Use a measuring tape that is long enough to span the entire length of the bar. A 12-foot or 15-foot tape measure is typically sufficient.
Lay the measuring tape flat against the top of the bar, starting at its leading edge (the end with the sprocket).
Ensure that the measuring tape is taut and not sagging, especially when measuring longer bars.
Hold the tape measure perpendicular to the bar, ensuring that it does not angle away or towards either side.
Read the measurement at the point where the tape meets the trailing edge (the end opposite the sprocket).
Record the length of the bar in inches. If the measurement falls between whole inches, round it up to the nearest whole inch.
For maximum accuracy, repeat the measurement process two or three times and average the results.

By following these additional guidelines, you can obtain a highly precise measurement of your chainsaw bar, ensuring that you select the correct replacement blade or bar for your specific model.

How to Measure a Chainsaw Bar

Measuring a chainsaw bar is a crucial step when selecting a replacement or ensuring proper fit for your chainsaw. Here’s a step-by-step guide to measure the length of a chainsaw bar:

Locate the mounting holes: Identify the two mounting holes on the bar where it attaches to the chainsaw.
Measure between the holes: Use a measuring tape or ruler to measure the distance between the center of the two mounting holes.
Round to the nearest inch: The measurement obtained will be in inches. Round the result to the nearest whole inch, as chainsaw bars are typically sold in inch increments.

Example:

If you measure a distance of 17.75 inches between the mounting holes, round it to 18 inches. Therefore, your chainsaw bar length is 18 inches.
