Image Sizing Requirements for Top eCommerce Marketplaces and Channels

images requirements

Many DIY product photography guides are now available to make it easier for eCommerce business to get high-quality product images.

Following a few simple rules about product photography will give you amazing and consistent product photos, even with a tight budget.

What’s tricky, however, is that eCommerce marketplaces and platforms have their own image sizing requirements. Regardless if you’re an omni-channel retailer or not, it’s important you keep track of these varying requirements.

Importance of high-quality product images

Product photos are probably the most underrated aspect of an eCommerce brand. I wouldn’t be surprised if you told me that product photography is the last thing you wanted to spend on.

But when it comes to selling online, your first impression really counts. Your product images help in creating a good impression of your brand and keeping potential customers engaged.

Having high-quality product images also solves one of the things that online shoppers hate - not being able to try the product first. With professional product photos, you’re improving the customers’ experience by allowing them to visualize the details of your product.

Professional product photos help you increase your sales conversion, build trust in your brand, improve customer satisfaction and increase your social shareability. Photos are what your customers rely on before making that important decision to buy your product.

Why are image sizing requirements important?

For omni-channel retailers, it makes sense to understand the different image sizing requirements for top eCommerce marketplaces and platforms. But if you’re selling on one platform or channel only, you might think that this is a trivial matter.

On the contrary, it pays to know these different image guidelines. It helps you prepare and create a more streamlined image creation process for your products.

If you understand the different image sizing requirements, it will be a lot easier for you to manage your photos if you decide to transfer to another eCommerce platform or add another channel to sell your products on.

Woocommerce uses 3 types of product images - Single Product Image, Catalog Images and Product Thumbnails. The Single Product Image is the main/featured image.

While the recommended image size for WooCommerce is 800 by 800 pixels, you might want to use higher resolution images, especially if you want to take advantage of the zoom functionality.

Facebook and Instagram Ads

If you’re using Facebook or Instagram ads, it’s highly recommended that you follow their design recommendations to get the maximum value of the money you’re spending.

In general, Facebook recommends JPEG or PNG file types with image ratio of 9:16 to 16:9. For Instagram, minimum image ratio is 4:5 and the maximum image ratio is 1.91:1.

Universal product image guidelines

There’s no “one size fits all” when it comes to product image size for eCommerce websites.

The guideline below will allow you to create a streamlined image creation process for your images.

If you follow this, you won’t need to worry about reshooting your product photos, if or when you transfer to a different eCommerce marketplace or platform.

Image Size

Make sure your images are at least 2048px by 2048px. From all the platforms listed above, Shopify has the highest “recommended” image size of 2048px by 2048px.

With 2048px by 2048px, you can easily resize them to other sizes fitted for other marketplaces or channels.

Large “Product” Size

For best results, make sure the product itself fills out at least 85% of the image frame. Amazon is also strict about this.

A case study by VWO showed that slightly enlarged product images on the collection pages yielded a 9% increase in sales. So, it’s always a good habit to photograph your product images in focus.

Having a large product size also allows you to change the aspect ratio of your images without worrying about the quality of the product photos or the zoom functionality of your store.

File types/extensions

While JPEG/JPG is the most common file type used on eCommerce stores, I recommend saving a PNG version of your images as well.

If you’re targeting loading speed, you can easily convert PNGs to JPEGs later on. Use the JPEG/JPG version on your eCommerce stores, but save a PNG version for post-processing.

PNGs is a file extension that supports lossless data compression. This means that if the image is edited over and over again (without changing resolution or image size), the image does not lose its quality. So, if you need images edited multiple times, you can use the PNG version to ensure quality is not lost.

PNG file type also supports transparency unlike JPEG/JPG file type. If you’re aiming for flexibility, PNG will be more useful.

Image Background

Majority of eCommerce platforms and marketplaces recommend using a pure white background (#FFFFFF or RGB 255, 255, 255). Amazon is also very strict about this.

However, you might want to consider saving your images on a transparent background first. For platforms like Shopify, where there are no specific background requirements, it’ll allow you to easily add any background you like on an image with a transparent background.

If you’re selling on Amazon, you can easily turn the transparent background to white by converting the file to JPEG.

Tip: In most basic photo editors, like Paint, saving an image with a transparent background to JPEG will automatically turn the transparent background to white.

Regardless of whatever platform or marketplace you’re currently selling on now, make sure to always keep yourself updated with the latest image sizing requirements on different eCommerce platforms and marketplaces. The eCommerce industry is ever-changing. Keeping track of all these changes will help you stay on top of the game.
