Can I use sanded grout for wal tiles?

Hi,



I just watched a youtube video and a guy said that you should use a sanded grout for floor tiles only and only when space between tiles is greater than 1/8" and for everything else you should use an unsanded grout.
I am really confused. I was recommended and I am ready to use a sanded grout for wall tiling project with space between tiles 1/8".


Thanks
