Cardboard Boxes Guide

Measuring

Box dimensions refer to the internal (usable) dimensions and are always measured in the same order.

1. Longest opening dimension (length)
2. Shortest opening dimension (width)
3. Depth (height)

Depending on the board grade and flute, the internal and external dimensions of a box can differ significantly. Watch our ‘how to measure a box’ video to find out more.

Board Type

Corrugated cartons differ in strength depending on the combination of fluting, and weight of paper used, to create a solid board. A single wall box has one layer of fluting, and a double wall box has two (giving extra strength, better suited to heavier items).

Multiscore

Many of our boxes have a ‘multi-score’ feature, giving you the option to vary the depth of the box to a pre-scored dimension. Simply cut the existing slots (between the flaps), fold along the pre-scored crease, and you create a shallower depth carton.

Video: What Type of Box Do I Need?
Compare Single Wall, Double Wall and Enviro Boxes and discover which is best for your product

We sell various types of boxes, from standard duty single wall to extra heavy duty.

Single wall boxes are identified by the prefix ‘CSW’.

Heavy duty Enviro-boxes have a clear ‘Enviro’ print on one of the flaps.

Double wall boxes have a code starting ‘CDW’.

As you can see, our single wall boxes have a single layer of corrugated board. They are our best value option for packing lightweight goods.

Enviro-boxes are made from a thicker and more rigid single wall board. These are suitable for slightly heavier goods.

Double wall boxes have 2 layers of corrugated board, making them our strongest general-use boxes. They can be used to pack heavy items such as books.

We also sell extra heavy boxes, suitable for very heavy items such as engineering components.

Video: How to measure and find the right size cardboard box
Kite Packaging stocks a wide range of corrugated cardboard boxes in single wall, double wall and envirobox styles. Watch this video to find what size you need.

Step 1: How big is your product?

Standard box dimensions are given in the order Length x Width x Height.

Measure the length with a tape measure. Next, measure the width. Measure the height / depth.

Step 2: Select a box that is slightly larger in all 3 dimensions. This will allow for extra padding to protect your product.

You will need the INTERNAL dimensions of the box.

Depending on the board grade, this could be up to 10mm less than the external dimensions.

To check that your box is the correct size, measure the length, width and height on the INSIDE of the box.

All dimensions provided for our boxes are internal.

Step 3: Wrap your product in a suitable padding material and place inside the box.

It should be a snug fit to prevent movement.

Step 4: Close the box and seal with tape or strapping as required.

Consider our custom logo printed tape for a cheap branded sealing option.
