How to Write Amazon Product Dimensions
Despite a significant uptick in the number of consumers turning to online shopping, buying products online still comes with its downfalls. Not least the fact that buyers can’t touch or see a product in-person when browsing online.
Think about it: shopping in a brick-and-mortar store allows customers to handle products, see them up close, and get a feel for their texture and size – all things that are much harder to do when a product can only be seen on screen.
This means online sellers are having to be really specific when explaining how their products look, and dimensions play a huge part in this.
Listing product dimensions on Amazon comes with many benefits. Not only do they set clear expectations so that buyers aren’t disappointed, but they also help you stand out against competitors who don’t display accurate dimensions (or any at all, for that matter).
All of this is to say that product dimensions are a vital part of your Amazon product listings. The question is, is there a right way to write them?
How Are Amazon Dimensions Listed in Order?
Dimensions are essentially a formula of numbers that provide buyers with a solid understanding of a product’s size. This is especially important for products where size matters, like furniture and accessories that complement another specific item.
So how do you write this formula?
Amazon dimensions are listed in the standard way for measurements: length x width x height.
This is the common formula for dimensions for anything on any website, so it makes sense that Amazon follows this.

However, it ultimately doesn’t matter what order you list product dimensions in.
The length doesn’t necessarily have to come first, as long as it’s clear which dimension refers to which part of the product.
The end result tends to be the same for the shopper. That is, it’s usually easy enough for them to work out which measurement goes where depending on the item that they are buying and its general shape and size.
While it helps to write your product’s dimensions out in the standard order of length x width x height, it’s not absolutely mandatory.
But it does help improve the customer experience, as it means the customer doesn’t have to carry out basic geometry on their own time and it also avoids disappointment if the customer isn’t able to determine which measurement goes with which part of the product.
You can make the process slicker by adding in the identifier when listing dimensions.
For example, you can write 10L x 15W x 60H.
The letters here refer to length, width, and height and directly tell shoppers which measurement they are looking at.
What Do Amazon’s Product Dimensions Include?
Product dimensions are listed in the “technical details” section on an Amazon product page, but do these numbers refer to the product on its own or with packaging?
There’s a common myth that these dimensions involve packaging, but this isn’t strictly true.
The dimensions listed on a product page should only include the size of the product itself, sans packaging. This is because shoppers really only care about the size of the actual product and not how big the box is going to be that it’s delivered in.
The packaging dimensions can be listed separately if necessary (although often the size of the packaging isn’t important at all). When filling out the product information through your Amazon seller account, there is a section for “Package Dimensions” where this information goes.
The Importance of Product Dimensions for Amazon FBA Sellers
While customers don’t necessarily care about the size of the package you store and send their products in, Amazon does – particularly for FBA sellers.
The dimensions of the product in total – that is, including packaging and any add-ons – is used to calculate shelf space fees. Amazon uses this information to charge the right monthly storage fees, shipping fees, and any long term storage fees.
Amazon groups products based on their size and charges sellers accordingly. For example, small standard-size products (which includes packaging) can measure up to 15” on the longest side, 12” on the median side, and 0.75” on the shortest side. The dimensions increase in structured steps up until the “special oversize” category which is reserved for products that are over 108” in length.
See the table below for more information:
Amazon uses these dimensions to set FBA sellers’ fulfillment and monthly storage fees. For example, small products incur a fee of $2.41 per unit per month, while special oversize products are charged at $137.32 per unit per month.
It’s important to note that the dimensions listed here for sellers include packaging. They are also used to determine the cost of shipping.
When creating an FBA product listing, sellers are asked to enter the product dimensions and the packaging dimensions in separate fields. Amazon calculates the overall size to determine the FBA charges.
The packaging field won’t be shown on the product listings pages though, since it is irrelevant to buyers.
For example, let’s say a shopper is looking to buy this bathroom cabinet:
The dimensions read 45 x 45 x 13cm.
These dimensions are the size of the product as it is without its packaging.
Amazon Product Dimensions From the Buyer’s Perspective
Product descriptions are vital for buyers and they form an important part of the customer experience. If a customer receives a product that isn’t quite what they were expecting, they’re more likely to leave a bad review and not come back, which can have a negative knock-on effect in the future.
There are two key places on a product page where buyers go to find out the dimensions of a product.
Firstly, customers often look in the bulleted features list to find out the dimensions of a product.
If they don’t find them there, they’ll scroll down to the “Product Information” section and look at the “Technical Details”.
How and Where to Fill Out Product Dimension Information
The product dimensions are added when you upload a new product listing to Amazon from your seller central account.
When you click “Add a Product”, you’ll be taken to a form where you can fill out all the essential information about your product and any extra details you think might be useful to buyers.
It’s in this form that you’ll be asked for both the product dimensions and the packaging dimensions (remember though that the packaging dimensions won’t be displayed on the public product page).
How to Find the Dimensions of a Product?
If you’re thinking about selling a product and want to see what the average size is with your competitors, you can use a tool to do so. This will provide you with the median size of the best-selling examples of that product.
This is also a necessary activity if you are selling via FBA or via a method where you don’t get to see the products before you sell them.
Tools to Find Amazon Product Dimensions
If the product dimensions are listed on the product details page, you can use a free tool to get this information:
- CamelCamelCamel is an Amazon price tracker tool that serves up price history charts as well as average product dimensions for any products you search for
- Keepa does a similar thing for free – it creates price chart history and consolidates the most important information about best-selling products, like their dimensions
Alternatively, you can use a paid tool that has more features. These tools not only track the prices of best-selling products in your chosen categories, but they also provide tons of other information, like product analytics, sales information, most profitable keywords and more.
Paid tools for finding out product dimensions include:
- Helium 10 – this is a suite of tools designed to help you grow your Amazon store

The Importance of Amazon Product Dimensions
Amazon product dimensions might seem like a small part of your overall strategy, but they’re vital for maintaining customer expectations and ensuring buyers aren’t disappointed when their product arrives.
The dimensions listed on an Amazon product page don’t have to be in any particular order, but the standard formula is length x width x height. This doesn’t include packaging dimensions, although you will be asked for this information when filling out your product information on Amazon as they use it to calculate FBA fees, like monthly storage costs and shipping prices.
Listing product dimensions incorrectly can ruin the customer experience, encourage bad reviews, and lose potential lifelong customers. It sounds so simple, but it’s so important to get it right.
Make sure you upload the right product dimensions and display them in the places where customers look for them – the bulleted feature list and in the “technical details” section of the product information chart.
