4.1.2 - Change Banner Size?

Ive done a search, and all the threads do not seem to work to actually change the size of the banners. They are huge. Want to make them smaller. Any ideas? Thanks

Still have not figured this out =(

If you talk about Main slider banner on homepage, you can change it's width size by changing grid size of block's grid.

That is what we did. We create a new grid that was smaller, moved the block inside of that and then the banner on the main page was smaller.
