How to Calculate Dimensional Weight Easily

Shipping has become an integral part of business operations, and with this comes the challenge of understanding the cost of freight shipments. One of the major factors that affect shipping costs is dimensional weight. In this article, we’ll discuss what dimensional weight is, why it’s important, and most importantly, how to calculate it easily.

What is Dimensional Weight?

Dimensional weight is the weight calculated from the package’s volume rather than its actual weight. This is calculated using the package’s length, width, and height to determine the amount of space it will occupy in the transportation vehicle.

Dimensional weight is often used by shipping companies to determine the cost of shipping a package. This is because a package that takes up more space in a transportation vehicle will require more fuel and resources to transport, even if it is relatively light in weight.

It is important to note that not all shipping companies use dimensional weight as a pricing factor. Some may only consider the actual weight of the package, while others may use a combination of both actual weight and dimensional weight to determine the final cost of shipping.

Why is Dimensional Weight Important?

Dimensional weight is important because many carriers use it to determine shipping rates. In situations where your shipment is larger in volume than actual weight, it will be charged as the dimensional weight rather than the actual weight, which can result in higher shipping costs.

It is also important to note that dimensional weight can vary depending on the carrier and their specific calculation method. Some carriers may use a divisor of 139 instead of 166, which can result in even higher shipping costs for larger packages.

To avoid unexpected shipping costs, it is recommended to measure and calculate the dimensional weight of your package before shipping. This can be done by measuring the length, width, and height of the package and using the carrier’s dimensional weight calculator to determine the chargeable weight.

How to Determine the Length, Width, and Height of Your Package

Before you can calculate dimensional weight, you need to know the package’s length, width, and height. Measure the package’s length, height, and width using a tape measure or ruler and write down their values in either inches or centimeters.

It is important to measure the package accurately to avoid any discrepancies in shipping costs. Make sure to measure the longest point of the package for the length, the widest point for the width, and the highest point for the height. If the package has an irregular shape, measure the widest and highest points to ensure accurate measurements. Additionally, if the package has any protruding parts, such as handles or wheels, make sure to include them in the measurements.

The Formula for Calculating Dimensional Weight

The formula for calculating dimensional weight is straightforward. Multiply the package’s length by its width and then by its height. The result is the package’s volume. Divide this number by the dimensional factor specified by the carrier, and you will get the package’s dimensional weight.

For example, if a package’s dimensions are 20 inches by 16 inches by 10 inches, the calculation would be as follows:

20 x 16 x 10 = 3,200 cubic inches

If the dimensional factor is 139, the dimensional weight would be:

3,200 / 139 = 23.02 lbs

It is important to note that carriers may have different dimensional factors for different shipping methods. For instance, air freight carriers may have a higher dimensional factor than ground carriers. This means that the same package may have a different dimensional weight depending on the carrier and shipping method used.

Additionally, some carriers may round up the dimensional weight to the nearest pound. This can result in a higher shipping cost for the package, even if the actual weight is lower than the dimensional weight.

How to Use a Dimensional Weight Calculator

If manual calculations are not for you, you can use various tools such as dimensional weight calculators available on the internet. They will do all the work for you and provide you with an accurate dimensional weight value.

When using a dimensional weight calculator, it is important to input the correct measurements of your package. This includes the length, width, and height of the package. Some calculators may also require you to input the weight of the package.

It is also important to note that different shipping carriers may have different dimensional weight calculations. Therefore, it is recommended to use a calculator that is specific to the carrier you will be using to ensure the most accurate calculation.

Tips for Reducing Dimensional Weight Charges

Reducing the size of your package is the most efficient way to reduce the dim weight charge. You may use packaging products such as bubble wraps, or air pillows that would help you reduce the overall size of your package.

Another way to reduce dimensional weight charges is to use a smaller box or envelope. If you have a small item to ship, consider using a padded envelope instead of a box. This will not only reduce the size of your package but also the weight, which can further reduce the shipping cost.

It is also important to avoid leaving any empty spaces in your package. Fill any gaps with packing materials such as foam peanuts or crumpled paper. This will prevent the item from moving around during transit and also help reduce the overall size of the package.

The Impact of Shipping Carrier Policies on Dimensional Weight

Some carriers have different policies regarding how to calculate dimensional weight charges. Therefore, it is advised to check their policy first or ask for their guideline before you start your shipment arrangements.

It is important to note that the impact of shipping carrier policies on dimensional weight can have a significant effect on your overall shipping costs. For example, some carriers may use a volumetric divisor of 166, while others may use a divisor of 139. This means that even if your package weighs less than the carrier’s weight threshold, you may still be charged based on the package’s dimensions. It is crucial to understand the policies of each carrier you work with to ensure that you are not surprised by unexpected charges.

Understanding the Difference Between Actual Weight and Dimensional Weight

Actual weight refers to the weight of a package, including the weight of its contents and any materials used for packaging. Alternatively, dimensional weight is calculated based on the package’s size, as discussed above.

It is important to understand the difference between actual weight and dimensional weight, as shipping carriers often charge based on whichever weight is greater. This means that if you have a lightweight package that is large in size, you may be charged based on its dimensional weight rather than its actual weight. To avoid unexpected shipping costs, it is recommended to measure and weigh your packages accurately before shipping.

Common Mistakes to Avoid When Calculating Dimensional Weight

Mistakes can happen during the calculation process, which can lead to extra charges, penalties, or rejections during shipping. Common mistakes to avoid are incorrect measurements and not using the correct dimensional factor. Always double-check the measurements and confirm with the shipping carrier’s guidelines before submitting your shipment.

Another common mistake to avoid is not considering the packaging material’s weight and dimensions. The weight and size of the packaging material can significantly impact the dimensional weight calculation. It is essential to include the weight and dimensions of the packaging material in your calculation to avoid any discrepancies. Additionally, ensure that the packaging material is not excessively large or bulky, as this can also result in extra charges or rejections during shipping.

The Benefits of Accurately Calculating Dimensional Weight

Accurate calculations can benefit your business through financial savings on shipping rates. Providers such as UPS, FedEx, and DHL are among the companies that use dimensional weight calculations instead of actual weight. By accurately calculating the dim weight, you can avoid extra charges and increase your profit margins.

In addition to financial savings, accurate dimensional weight calculations can also improve customer satisfaction. By ensuring that packages are shipped at the correct weight, you can avoid delays and delivery issues caused by incorrect weight calculations. This can lead to happier customers and a better reputation for your business.

Furthermore, accurate dimensional weight calculations can also help with inventory management. By knowing the exact weight and size of your products, you can better plan for storage and transportation needs. This can lead to more efficient operations and cost savings in the long run.

How to Calculate Dimensional Weight for Irregularly Shaped Packages

Irregularly shaped packages are difficult to measure manually. One way to calculate the dim weight would be to place the package in a box, then obtain the box’s dimensions to calculate the dim weight.

Another method to calculate dim weight for irregularly shaped packages is to use a volumetric scanner. This scanner uses advanced technology to measure the package’s dimensions accurately, even if it has an irregular shape. The scanner calculates the volume of the package and then applies the dim weight formula to determine the chargeable weight.

It is essential to calculate the dim weight accurately for irregularly shaped packages as carriers charge based on the higher of the actual weight and the dim weight. Incorrect calculations can result in higher shipping costs, which can impact your business’s profitability. Therefore, it is crucial to use the correct method to calculate the dim weight for irregularly shaped packages.

A Step-by-Step Guide to Calculating Dimensional Weight

Here is a step-by-step guide to calculating dim weight:

1. Measure the length, width, and height of the package in either inches or centimeters.
2. Multiply the measurements to obtain the package’s volume.
3. Divide the volume by the dimensional factor provided by the carrier.
4. The result will be your package’s dimensional weight.

Which Shipping Carriers Use Dimensional Weight and Why?

Major shipping carriers such as UPS, FedEx, and DHL all use dimensional weight calculations rather than actual weight. The reason for this is that carriers have limited space on their vehicles, and larger packages occupy more space compared to their actual weight. Therefore, it is more appropriate to charge the customer based on the space they occupy rather than their actual weight.

How to Save Money by Optimizing Your Packaging for Dimensional Weight

You can save money by optimizing your packaging to reduce its size and increase its density. By reducing the size of the package, you also reduce the dim weight, which translates to lower shipping costs. Using lightweight packaging materials also helps in reducing the overall weight of your packages.

Conclusion

Calculating dimensional weight is a crucial part of shipping, and knowing how to do it accurately can result in financial benefits for your business. Be sure to check with the shipping carrier’s guidelines to ensure that your calculations are accurate and optimized for the best shipping rates possible.
