How To Measure Box Dimensions?

Box dimensions are measured in standard order, like length, width, or height (L x W x H). Length is the longest dimension of the box, width is the short dimension of the box, and height is the vertical side of the box. With these three measurements, you can easily get the exact box size or have one made that perfectly fits your products. You can also measure the box dimensions with the help of a ruler, but it is difficult to measure the box inside with the ruler.

Measurement By Length

You can measure the dimension of the box by its length (longer side). You can also measure it from edge to edge.

Measurement By Width

Measure your box by the short dimension of the box that is called width. Width is perpendicular to the longest side of the box (length).

Measurement By Height (Or Depth)

Measure your box from top to bottom to know the height of the box.

2D or 3D Box Dimensions

You can add different dimensions to the box. They can be 2D (two-dimensional) and 3D (three-dimensional). But usually, a box is measured in three dimensions: length, width, and height.

Length is the longest, width is the horizontal side, and height is the vertical dimension of the box. It also depends on what kind of box you have or what shape you want.

Round Boxes: A Different Kind of Measurement

Do you know that the measurement of a square or rectangular box is easy, but how could you measure a round box? You can measure the square or rectangular boxes easily, but the difficulty is that the round boxes have no corners. So how did you measure the length, width, and height of the round box?

You can measure the round boxes by their diameter or radius. Radius is the half distance of the circle, and diameter is the double of the radius. You can also use a measuring tape for the measurement of the round box. Now it is easier to calculate the measurement of a round box by its radius or diameter.

How To Calculate The Volume of A Box?

To fit your product perfectly, it is necessary to determine the volume of the box. After measuring length, width, and height, you can measure the volume of the box for more accuracy. You can guess from the volume whether the box is strong or not, and if it is perfect for shipping or not. Because volume plays an important role in choosing material, it reduces wastage, reduces costs, and improves the structure of packaging. You can calculate volume in cubic centimeters by:

Volume = Length x Width x Depth

What Is The Difference Between Interior and Exterior Dimensions?

It is necessary to understand the concept of interior or exterior dimensions before purchasing the custom box packaging. To pack the product perfectly in a box, the right size is necessary. So now understand the difference between interior and exterior dimensions.

The Issue of External Dimensions

Do you think that there is no issue in measuring the box? Are you thinking that just checking the length, width, height, and volume is enough? No, there are different things you should consider before customizing your box. You need to understand the importance of internal and external box dimensions.

Because the dimensions of the outside and inside of the box are different from each other. Outside dimensions are larger and measure the thickness of the box. If you do not measure it accurately, the product will not be packed perfectly, and that leaves a bad impression on customers.

While the inner dimensions are the inner parts of the box. So, if you want to protect the product, you need to measure these dimensions carefully. Because if you add extra features (like cushioning) in a box it can be small for the product. You need to be more careful if you want corrugated cardboard boxes for your product. Because it is made with three fluted thick materials, sometimes you need to increase a few millimetres according to your product.
