When it comes to cardboard packaging, many questions come into people’s minds, such as whether they are biodegradable. What is the dimension of cardboard packaging? While we often pay attention to the dimensions of these boxes, have you ever wondered just how much they weigh?

In this comprehensive guide by Custom Pack Box, we will break down the weight of cardboard boxes in various units, from pounds and ounces to kilograms and grams. We will also discuss the weight of a large cardboard box.

Let’s get started without any delay!

How Much Does a Cardboard Packaging Weigh in Pounds?

A 12x12x12 corrugated cardboard box is best used for shipment and storage. How much does it weigh? Knowing this is important when picking a shipping box size.

The answer depends on the cardboard box. The average 12x12x12 cardboard box weighs 4-6 pounds if it’s empty. Wall thickness, corrugated material (single or double wall), and staples or tape reinforcements for heavier contents determine a cardboard box’s weight.

Double-wall 12x12x12 cardboard boxes weigh 6 pounds, whereas single-wall weighs 4. You can Ship books, laptops, and other heavy items in double-walled boxes. Knowing the box contents should help you pick a cost-effective strength/weight class that protects against transport abuse!

How Much Does a Cardboard Box Weigh in Ounces?

Standard 12x12x12 corrugated cardboard boxes are single-wall or double-wall. As indicated, they weigh 4–6 pounds when the box is empty. A pound has around 16 ounces. You can easily calculate your cardboard box’s ounce weight.

For a single-wall cardboard box:

Weight in ounces=4 pounds×16=64 ounces

For a double-wall cardboard box:

Weight in ounces=7 pounds×16=96 ounces
Therefore, a 12x12x12 single-wall cardboard box weighs approximately 64 ounces, and a double-wall box weighs about 96 ounces. As mentioned these are weights depending on the material used since each paper stock has different grammages and these factors can affect the weight of the box significantly.

How Much Does a Cardboard Box Weigh in Kilograms?

For those who use the metric system, the weight of boxes is measured in kilograms. To convert the weight of the box from pounds to kilograms, you can use the following conversion factor:

  • 1 pound = 0.453592 kilograms.

Apart from this conversion, we must go through a few steps to determine how much a cardboard box weighs in kilograms.

  • First, we need to calculate the box’s volume in cubic centimetres. We can do this by converting the dimensions (L*W*H) from inches to centimetres. Each inch of the standard cardboard box is about 2.54cm, so when we multiply 12 inches by 2.54, we get 30.48 centimetres for each dimension.
  • Now, we calculated the box dimensions in cm, and we can directly measure the packaging volume. We must multiply the length, width, and height (centimetres) to get the volume in cm³. Then, to find the weight in kilograms, we divide this volume by 6000.

So, let’s do the math:

  • Volume = 30.48 cm x 30.48 cm x 30.48 cm = 28316.8466 cubic centimeters
  • Weight = 28316.8466 cm³ / 6000 = 4.7194 kilograms

Therefore, the weight of the cardboard box is approximately 4.72 kilograms.

How Much Does a Cardboard Box Weigh in Grams?

You can break it down into grams if you need a more precise measurement. It’s easy to measure the weight of the box in grams. What do you have to do? Simply multiply the weight of the box in kilograms by 1000. So now you can measure the weight of the box in grams:

  • Weight = 4.7194 x 1000
  • Weight = 4719.4 grams

To convert the weight of a cardboard box from pounds to grams, you can use the following conversion factor: 1 pound = 453.592 grams.

Look at the table below for a better understanding of how varying sizes and thicknesses of boxes weigh in grams!

Box Size (Inches)Average Weight (Grams)
6 x 6 x 6120-150
12 x 12 x 12200-250
18 x 18 x 18300-350
24 x 24 x 24400-450


How Much Does a Large Cardboard Box Weigh?

Large cardboard boxes are commonly used to ship bulky items. These boxes are heavier in size due to the extra material used in their manufacturing required for strength and durability. You can calculate the weight of a large cardboard box by using the above-listed formulas in ounces, pounds, kilograms and grams.

Note: The weight of the cardboard box calculated by the above-listed formulas is the only estimation based on its dimensions. Keep in mind that the exact weight can be varied according to the thickness of the material. It’s advised to use the scale to measure the weight of the box.
