When you need to send, save or view your products, it is very important to know the difference between internal and external measurements. These measurements help you ensure that your product fits well and that you do not pay too much for shipping.

Even a small mistake in measuring can cause problems, like broken items or wasted space. For businesses, especially new ones or small shops, knowing how to measure boxes the right way can save money and keep customers happy. At UPacked, we often get questions about the best way to measure for custom packaging. Learning this simple step can help everyone make better choices. If you want to order custom packaging or avoid common mistakes, it is good to know these basics. Also, if you are looking for custom tuck boxes, getting the right size is very important so your product fits just right.

What Are Exterior Measurements?

External measurements are the forms you find outside the box. These figures are important for shipping and storage. Shipping companies use size to see how much your box will take place in a truck or warehouse. They also use these numbers to fulfill shipping costs, so a slight difference can also change how much you pay.

To measure the exterior, close the box and use a ruler or ribbon to measure each side from one out of the edge of the other. If you need to stack boxes in a warehouse or store shelf, the outer size tells you how many boxes you can fit. It is also important for stores that need to view products on the shelves. For companies working above, it helps to know that external size improves your shipping and storage plan.

Key Differences Between Interior and Exterior Measurements

The main difference between internal and external measurements is the thickness of the box walls. Internal measurements only show location inside the box, while external measurements include walls. This may not seem important, but for customized packaging it can do a lot. If you use the outer size when using inside, the product may not fit. If you use the inner size when using outside, you can pay more for shipping.

For example, if your product is exactly 10 inches long and you order a box with an exterior length of 10 inches, the inside will be a bit smaller, so your product will not fit. If you use the interior size, you know your product will fit just right. This is why most custom packaging companies, like UPacked, always ask for interior measurements for custom orders.

Another big difference is how these sizes change your costs. Shipping companies charge by the size and weight of your package. If you use a box that is too big, you pay more for shipping and waste space. Using the right size helps you save money and use your space well.

Why Accurate Measurements Matter

Correcting the measurement is important for many reasons. First, it protects your products. If the box is too big, things can rotate and break. If it is too small, you may not be able to close the box or fit the product inside. Good measurements also improve your products when customers open boxes. A good fit shows that you care about your product.

Shipping and storing are other reasons why measurements matter. Shipping companies use the outside size to decide how much to charge. If your box is a bit bigger than needed, you could pay more. 

Common Mistakes and How to Avoid Them

Another mistake is to forget to make room for the package material, which can make the boxes for tight or difficult to close.

Sometimes people use different devices for different aspects of the box, which can cause errors. Always use the same device - either empty or centimeters - for all your measurements. Writing measurement in the right order is also a good idea: Length x width x height. See your number before sending the packaging partner.
