The box size is divided into outer size and inner size. For the card box, the difference between the inner size and the outer size is not very large. But for high-end custom gift boxes, the difference between the two is very large, and it can often reach a difference of about one centimeter, because high-end custom gift boxes are mostly made of cardboard or MDF, and cardboard and density have a certain thickness .

If this size is wrong when the box is customized, it will cause serious quality problems. For example, it may cause the inner tray to not be put in, and the facial paper package is not allowed. Many customers don't understand this. Let's talk about the internal and external dimensions.

First of all, we need to understand what the inner and outer dimensions of the box are. The outer dimensions are actually the outer dimensions of the box that we often talk about. You can measure the box with a ruler; the inner dimensions are measured with the ruler inside the box. Capacity.

For professional custom gift box manufacturers, as long as you know one of the inner and outer sizes, you can launch another size. The difference between the inner and outer sizes is the thickness of the box material. If it is a cardboard, the general thickness will not exceed 0.5 mm, so there is not much difference between the internal and external dimensions. But if there are some customized gift boxes, the material will even reach 3 cm, so the size difference between inside and outside is very big. Some manufacturers of customized packaging boxes regard the outer size as the inner size, which will cause the box to be smaller and not fit into the product.
