What is the optimal image size for maintaining quality in a theme slider?

[rory123]

Hi there

So ive changed my theme and cannot get the right size of the image for the slider.. Ive tried 1500x600, 1920x1080 and a few different dimensions. Its either too small and shopify ruins quality of the image or too big. 

Can anyone advise me on what image size to use so the quality stays the same and the image doesnt expand?

Not sure where to find that. Ive got some option in the menu where i upload image but it only has 'height' option and that is not useful without width.

Hi @rory123,

Each theme will have a guideline for image sizes and dimensions, you should submit a ticket to the theme developer for the format that work best for your theme. Hope this information can be useful to you.
