If you have the widget embedded on your site and the size is not being shown properly check:
1. You're respecting the chosen system of measumerent (cm / in)
2. You're respecting the chosen size style (HxW / WxH)
3. If you're working on a platform, check the sizes have been input as an element, not a text (for common platforms visit our widget documentation)
If you have more than one size and you need the widget to detect them all, visit our solution article about it.
Please know that the widget will work primarily pulling the height value and will automatically calculate the width as per the aspect ratio of the image uploaded.
