How to Measure Dimensions of a Box

The dimension of a box is directly related to the lengths of the three dimensions of a box. You can easily measure the dimensions of a box by following three easy steps.

  • First of all, measure the length of the box. The length of a box is the lengthiest side once you hold the box at 90 degrees.
  • Now, turn the box 90 degrees again and calculate the width.
  • Lastly, calculate the height of the box, which is the remaining side of the packaging.

Dimension = Length x Width x Depth 


Let’s say a box has dimensions of 10X20X30 in length, width, and depth respectively. You can multiply these values to get the actual dimension to make a box accurate for products.

10” X 20” X 30” = 6000”

Significance of Box Measurement

The objective behind the packaging is evident from daily life usage of packed products. Packaging protects the products, we all know, but the packaging also promotes a product and helps satisfy customers. In short, protection is the primary goal, but it also performs many other duties for products. If proper measurements are not made, all these packaging functions may counter-perform all these duties.

In other words, Box measurement is essential to let a box perform all its essential duties. A well-measured and manufactured box provides the best protection for the products and keeps them secure from any damage during transportation.

Therefore, we always take careful measures and provide the clients with 2D & 3D Free Mockups before an order is shifted to the production department. You can look at our designs to analyze the specific measures taken by our beloved clients.

How to Measure the Girth of a Box

How to Measure the Girth of a Box


Measurement around the circumstances of a box is girth, and it is more expansive than the actual width. The girth of a box is essential primarily when you ship your boxes from one place to another. Secondly, packaging experts also measure the width of boxes with cylindrical shapes.

You need to measure the width and height if you want to calculate the girth of a box.

For a better understanding, look at the formula:

Girth = (H + W) X 2


If we use the instance of a box of 30X20in, we will multiply the width (15 inches) by 2. This would give us 30. Then we take the height (10 inches) and multiply it by 2. This would give us 20.

We then add the results together to get the girth.

30in + 20in = 50in.

How to Calculate the Volume of a Box

How to Calculate the Volume of a Box


You can calculate the volume of a box with its length (L), width (W), and height (H). First, you need to measure these values and then use its formula for calculating volume.

You can calculate the volume of your boxes by the following formula:

Volume = L X H X W

If we use the instance of a box of 10 L, 5 W & 20 H, we will multiply all these values with each other.

Volume = 10 X 5 X 20 = 1000

Dimensions of a Box Depends on the Product

Dimensions of a box based on the dimensions of a product. So, the dimensions of the products are measured, which is later used for assembling boxes for these products. However, you need proper preparations for measuring the dimensions of a box, as discussed below.
