Medium-Sized Box Dimensions: A Complete Shipping Guide

Packaging is the first thing your customers get to interact with, even before the actual product. It speaks louder than anything. It shows the customer what the brand really is and how it cares about the user and his experience. It is always recommended to pay keen attention to your packaging because most brands ignore it, and it directly affects sales.

Almost every industry uses different types of shipping boxes to deliver their goods. The most common size is always medium, regardless of the industry. Different dimensions are considered medium in different industries. Medium pizza boxes and medium size shoes boxes have entirely different dimensions; the height, width, and length are all different. It’s crucial to keep this aspect in mind before stepping right into getting shipping boxes. In this detailed blog, you will get to understand the dimensions of medium-sized boxes in different industries, so you can select the right dimensions for your products:

Why Do Dimensions Matter?

The dimensions of the box matter the most when looking for ideal packaging for your products. The product may get damaged during shipping if the packaging box doesn’t fit the product perfectly. Before placing an order for shipping boxes, determine the right dimensions. Only with the right dimensions can you choose the ideal packaging to ship your products in.

A box of the right size protects your products while shipping.
The wrong size can damage the visual appeal, as the products either crumble up inside or sit in any corner of the box.
Ordering the wrong-sized box results in significant capital loss.
Too big a box can cost you more than the price of the box, and it also incurs additional shipping costs, as a lot of carrier companies charge based on the size of the box.
Shipping in big boxes may also require additional fillers that cost extra dollars.
Receiving products in a nicely fitted and packaged box enhances the customer’s experience.

Standard Box Dimensions

The size and dimensions of any shipping box refer to the exact measurements of its length, width and height, written in the exact order of L × W × H. These dimensions tell you exactly how the product would fit inside the box. Having a clear knowledge and understanding of your box measurements is essential before you buy the packaging boxes. The following table shows the general and standard sizes used by a majority of courier manufacturers and users:

Box Types	Dimensions in Centimetres	Dimensions in Inches
Small Box	20 × 15 × 10 cm	8 × 6 × 4 in
Medium Box	30 × 23 × 15 cm	12 × 9 × 6 in
Medium Large Box	41 × 30 × 20 cm	16 × 12 × 8 in
Large Box	50 × 40 × 30 cm	20 × 16 × 12 in
Extra Large Box	60 × 50 × 40 cm	24 × 20 × 16 in

How To Measure Box Dimensions

The dimensions of a box are always measured in order of Length × Width × Height. It is crucial to measure the accurate dimensions in the right order.

Length: The longest dimension of the shipping box

Width: The dimension of the shorter side of the box

Height: The measurement of the box when standing upright

Medium Sized Box Dimensions

Medium-sized boxes are most commonly used for shipping. There is no absolute dimension for a medium-sized box. It all depends on the industry and the product you are using the box for. The standard medium size is somewhere between the following two dimensions:

Medium Box: 30 × 23 × 15 cm
Large Medium Box: 41 × 30 × 20 cm

How To Measure Your Box Size?

Most people think knowing the dimensions is enough, but understanding how to actually measure the exact dimensions is crucial. You can measure the dimensions of your shipping box in two ways, internally and externally. It’s important to have a word with your manufacturer to know if their measurements are internal or external.

Internal Measurements: These are the dimensions measured from inside the box. It gives you the exact space available in the box for your product.
External Measurements: These dimensions are measured from outside of the box. This is not ideal for ordering the packaging box based on these dimensions, as these are always larger than the internal dimensions based on the material thickness of the box.

How Couriers Measure Size

When you choose a shipping box for your products, you may look for the right quality and the right size box for safe delivery. But when you reach out to a courier company, they use different metrics. They calculate something called Dimensional Weight. The formula to calculate dimensional weight is as follows:

Dimensional Weight= (L × W × H(cm) ) ÷ 5000

This is the formula most courier companies use in the UK. Due to this formula, at times a large but lightweight box costs more in shipping fees than a small but heavier box.

Courier Size Limits

Different courier companies in the UK have different criteria for Medium Sized Box in terms of both size and dimensional weight. The following table demonstrates whether your medium-sized box falls within their limits.
