Hi, responsive ratio is width / height ratio of the slider. If your images are for example 1920 x 1080 then responsive ratio is 1920 / 1080 which is 1.78. If your images are 1000 x 500 then ratio is 1000 / 500 which is 2. Hope this helps, please let me know if you have more questions or please update the rating 🙂
Cheers
We have since switched to another plugin. In fairness to the dev, I’m updating the rating for their response. I don’t think this was obvious from the documentation though.
