Images are one of the most important parts of any online store. However, there are so many different WooCommerce product image size types used in WooCommerce, it’s not always easy to figure out where you can change them to suit your specific needs.
Because WooCommerce images can get a little complicated, we’ve put together this guide to go over each aspect of WooCommerce images, so you can skip ahead to the part that suits you.
The plugin mentioned in this guide:
- WooThumbs for WooCommerce – Change your WooCommerce product image sizes without the hassle and improve your WooCommerce product gallery.
In this guide we’ll show you:
What are the benefits of setting your WooCommerce product image sizes?
Before we dive into the ‘how’, you may be wondering about the why? After all, it’s extra effort and time that you could be spending on your business, right?
The primary benefits of setting your WooCommerce product image sizes are:
- Preventing image blurriness — images that are the wrong size can appear blurred, giving a bad first impression to your buyers.
- Speed — the larger an image, the longer it takes to load, and it’s a well-known fact that slow websites result in less revenue and unhappy users.
So now we know why you should be spending some time on your WooCommerce product images, now let’s dive into the how.
What’s the best size for WooCommerce product images?
The best size for WooCommerce product images largely depends on the theme you’re using for your store and if you’re using an image zoom plugin like WooThumbs or not.
If you’re selling a simple product like a plain t-shirt, you may be able to get away with an image size that’s 800 – 1000px wide.
If you have a product that’s detailed or complicated however, uploading a larger image will allow potential customers to zoom in and see those details up close. In that case, an image that’s 2000px wide may work better for you.
Note: Never upload an image that’s too large. An image that’s oversized will slow your site down and as a result, will likely affect sales.
How to set WooCommerce product image sizes
Image sizes can now be configured under the Customizer. Go to Appearance > Customize > WooCommerce > Product Images.
Here you can set the Main image width, Thumbnail width, and Thumbnail cropping.
Image heights have intentionally been removed, as they are calculated automatically based on your settings. It’s worth noting here that your main, or ‘single’, product image no longer has any crop settings; they will always show uncropped.
As soon as you make any changes to these settings, WooCommerce will automatically generate the new image sizes. This may take a little while to process, but it runs in the background.
If you want to see the status of the background regeneration, you can go to WooCommerce > Status > Logs and select the log from the dropdown beginning with wc-image-regeneration.
How to set the WooCommerce category image size
In WooCommerce 3.3+, catalog image sizes have been removed. Instead, the catalog uses the same settings as the thumbnail settings. To change this, go to Appearance > Customize > WooCommerce > Product Images > Thumbnail Width.
If the main image width and thumbnail width fields are missing
You may notice that the Main image width and Thumbnail width settings are missing from your Customizer screen.
Not to worry, if your theme has declared WooCommerce support and pre-defined those settings, then they are removed from the Customizer.
WooCommerce also comes packaged with some popular theme support declarations. This means they already set the best image sizes for your theme.
But often you’ll find these settings elsewhere in the admin area. Either in your theme’s settings page, or the theme settings inside Customizer. If they’re nowhere to be found, then your theme may be very strict on the sizes it uses and not allow them to be easily changed.
If in doubt, contact your theme developer or use their support sytem to double-check.

WooThumbs for WooCommerce also allows you to set the image sizes in your product gallery.
- Go to WooCommerce > WooThumbs > Display

- Large Image Size – Choose a size for large images. Hover zoom and full screen will both use the size you select here.
Common WooCommerce image problems
Sometimes when configuring your WooCommerce product images, you may run into a few problems, some of which can be fixed fairly quickly.
We’ve put together some of the most common here, but if you have any more, please leave a comment below and we’ll see how we can help.
My WooCommerce product images are different sizes
If your product images are showing up as different sizes in your WooCommerce store, there are a few things you can do:
- Make sure all your product images are the same size before uploading them. Our recommendation is to create a template using an image editor that you can use for every product image. See ‘What’s the best image size for WooCommerce products?’ for the best image sizes to use.
- Ensure you’ve adjusted your WooCommerce product image settings to include thumbnail sizing and cropping.
How to set WooCommerce thumbnail cropping or hard crop in WooCommerce
To change how your thumbnails are cropped in WooCommerce, simply do the following:
- Go to Appearance > Customize
- Then go to WooCommerce > Product Images
- Select the desired cropping setting in Thumbnail cropping. You can experiment here and see changes in real time.
- Once happy, click Publish and your changes will be live.
My WooCommerce product images are blurry
If your WooCommerce product images are blurry then you’ll want to check a few things:
- Is your image quality good in the first place? Check the quality of your product image. If it’s low quality, when added to your WooCommerce store, it won’t look as crisp and clear as you’d like.
- Check your thumbnail settings. If your settings are looking for a 500px image for your product page and a 150px image on your catalog page, but you only upload a 150px image, then WooCommerce will automatically enlarge your image, causing it to look blurry.
To fix this problem, our tutorial for fixing WooCommerce blurry images will help.
