How to measure a box

Ensuring you get the right fit.

On one hand, the variety of boxes available and the range of corrugated cardboard sizing is incredible. On the other hand, obtaining a box that's just a teeny bit too small for your items, or one that's so large that your precious cargo can rattle around, is a nightmare.

Let's help ensure your box is the perfect size.

1. What the measurements mean.

There are three main measurements required for a cardboard box:

LENGTH (L) - This is the longest side of an object, typically measured horizontally from end to end along its base or opening.

WIDTH (W) - This refers to the distance extending from the front of an object to the back.

HEIGHT OR DEPTH (H) - This refers to the horizontal measurement of an object from top to bottom. It essentially measures how "deep" or thick the object is.

WHAT ELSE YOU NEED TO KNOW:

If you are looking at corrugate boxes online, the measurements will always refer to the inside measurements of the box. This is why it's important to measure the length, width and height internally, not externally.

The external measurements will depend on the thickness of the corrugated board that you select.

2. Measure the length

Firstly, ensure the top, or the open part of the box, is upright. Then, ensure the box is on a secure flat surface.

Take out your measuring tape or ruler and measure the LENGTH, or the longest side, inside the box, when the box is correctly facing upward. Record this figure.

3. Measure the width

Now measure the WIDTH, or the side of the box, from front to back, again from the inside. Record this figure.

4. Measure the depth

Now measure the box from top to bottom to derive the DEPTH, or HEIGHT, of the box. Record this figure.

5. Double check your measurements

The best way to ensure you have the correct measurements is to measure them again.

AND FINALLY:

If you need the external measurements of the box for shipping, you can repeat the above steps, measuring the outside of the box.
