Images for ecommerce: ideal formats and the new 3:4
Choosing the right image format for ecommerce has a direct impact on user experience. A practical guide to formats and the new 3:4 available in Shoptic.
Images for ecommerce: which format to use and why it impacts UX
Choosing good images for ecommerce is not just about aesthetics. Image format directly proves how your store looks, how users navigate it and, in many cases, whether they end up buying or not.
One of the most common mistakes is uploading images without considering the format expected by the store’s layout. The result: awkward crops, empty spaces and poorly structured product pages.
Why image format matters in an online store
Every ecommerce template is designed to work with specific image ratios. When images don’t respect those proportions:
- Important parts of the product get cropped
- Unwanted margins or blank spaces appear
- The catalog loses visual consistency
- Navigation becomes less fluid, especially on mobile
In a mobile-first environment, these details have a direct impact on UX (user experience) and brand perception.
Most common image formats used in ecommerce
Square format (1:1)
This is the most traditional format. It’s widely used in marketplaces and simple catalogs.
- Best for: product listings and marketplaces
Vertical format 9:16
This is the standard format for social media.
- Best for: Reels, Stories and vertical ads
- Not recommended: product pages
Horizontal format 16:9
Adds context and a sense of environment.
- Best for: banners and wide lifestyle scenes
Vertical format 3:4 (key for ecommerce)
The 3:4 format is one of the most commonly used in modern ecommerce because it:
- Makes better use of vertical space
- Fits product pages more naturally
- Reduces cropping and distortion
- Improves readability on desktop and mobile
- Creates stronger catalog consistency
