Why We Need To Measure Backpack Volume

While you are traveling, the backpack that you need is that which is capable of holding all what you need to survive out there. When you are looking for a backpack, the size is an important factor to consider. This can be established by knowing what the bag’s capacity is. How do you know which backpack has the right size for your needs? You can measure the backpack volume to find out. This article explains how to measure backpack volume and offers tips on choosing the right backpack. When you are looking for a backpack, the size is an important factor to consider. How do you know which backpack has the right size for your needs? You can measure the backpack volume to find out. Backpack volume is measured in liters. To measure backpack volume, you will need to know the dimensions of the pack and its capacity. The dimensions of a pack are typically listed in inches or centimeters. Capacity is usually measured in liters or cubic inches/centimeters. Backpack volume is an important factor to consider when purchasing a backpack. Unfortunately, there is no industry standard for measuring backpack volume. In this article, we will discuss three methods for measuring backpack volume and provide examples of each. There are different ways to know this capacity, but the main point to remember is to consider how much space is left in the backpack after one is done with its contents.


How to Measure Backpack Volume

Method 1: Measure Backpack Volume With a Ruler

The first method for measuring backpack volume is to use a ruler. This method is the most accurate way to measure backpack volume. However, it can be time consuming and may not be feasible for large backpacks.

To use this method, measure the length, width, and height of your backpack. Then, multiply the length by the width by the height to calculate the backpack volume.

For example, if your backpack measures 18 inches long by 12 inches wide by 6 inches high, the backpack volume would be 216 cubic inches.


Method 2: Measure Backpack Volume bWith a stuff and measuring cylinder.

Some people would use the Volume = Length x Width x Height formula, but that is actually incorrect. It is because this formula is for measuring the volume of a box. However, most backpacks are not in the shape of a box. Instead, backpacks usually come in irregular shape. More importantly, the size of the backpack is not our concern. What we want to know is the storage volume of the backpack. You could have a very big backpack which is heavily padded all around, which leaves only very little storage space inside. In that case, shall we consider it as a “Big” backpack or a “Small” backpack?

So, to make it clear, what concerns us should be the storage volume, which is the capacity inside the backpack that is available for your to put things. Make sense?

The method I am going to show you below is very easy to use and most backpack and outdoor gear manufacturers use this method to measure their backpack volume.

1) First, you need lots of little balls or beans

We use plastic balls with 10mm diameter, but you can use anything available such as Ping Pong balls or dried beans. You need lots of them.

2) Fill the backpack using a measuring cup

Fill the backpack with balls/beans until it is completely full.

Some would fill the main compartment only, and others would also include the outside pockets as well. There isn’t really a standard. In my opinion, I would include the outside pockets as well because they also contribute storage capacity.

3) Just count how many cups of balls/beans you have filled

You can get the accurate volume of the backpack by checking the amount of balls/beans you have filled in.

For example, if you are using a 1L measuring cup, and the backpack can take 20 cups of ball/beans, then the volume of the backpack is simply 20L. This is straight forward, right?

I hope that the information above is useful. Please feel free to leave your comments if you have any.
