How to Measure Your Box Correctly

Custom box sizes exist to protect your products and enhance presentation. And while we’ve provided some of the more popular options per industry, you can also choose to customize your custom box size with the help of UPrinting.

Here are some tips for getting custom box sizes correctly before you print.

1. Stick to a consistent format: L x W x H

Always list your box dimensions in the same order—Length x Width x Height. This helps avoid confusion during production and ensures your box is exactly the size you expect.

2. Understand each side of the box.

Packaging groups usually follow this format when determining the sides of the box:

Length is the front-to-back side of the box, where the main design typically goes. It’s usually the longest side by the opening.

Width is the shorter side of the opening, commonly where product info or barcodes are placed.

Height measures from the box opening to its base, the top-to-bottom distance.

3. Always measure from the inside.

Internal dimensions matter most. Always measure from the inside edges of the box to ensure your product fits comfortably, especially when adding inserts or padding.

4. Allocate space for product movement.

Your box should be snug with the products but not too cramped. Leave a small amount of space so the items don’t get crushed or deformed. You may also want to leave room for protective wrapping, such as bubble wrap, tissue paper, or foam.

Finding the right box size is the first step in creating well-rounded and dependable packaging that protects products and promotes the brand. Get started today and let UPrinting help you give your packaging the professional edge it deserves.
