Tips for Determining Sizes When Customizing Packaging Boxes

Since products vary greatly in size, there are no standard dimensions for packaging boxes. Therefore, when customizing packaging, the size must be carefully determined based on the specific product and its requirements.

Many people assume that as long as the product fits inside the box, the size is acceptable. However, selecting the right dimensions involves more than just fitting the product. Factors such as inner supports, material thickness, and overall proportions must also be considered to ensure the packaging looks good and functions properly.

For instance, if you want to create a high-end packaging box for a small product, simply following the “fit” standard is not enough. You should first determine a visually appealing box size, then adjust and slightly enlarge the dimensions as needed.

For fragile products, inner supports are essential. In these cases, the box size should be calculated by adding the minimum load-bearing width of the inner support to the product’s dimensions. Additionally, for products with special shapes—such as squares—the packaging box is often designed as a rectangle to improve visual appeal and balance.

These tips are based on years of experience in the packaging industry and are intended to guide you in choosing the right box size when customizing packaging. If you have other ideas or suggestions, we welcome your feedback.
