This is a resource that you definitely need. Storyboards are an amazing tool to visualize how a scene will turn out before adding dialogue and music. It allows you to be able to find potential problems before a scene is filmed. I can’t really draw much, but I still use them for planning out shots.
This resource is a site that has printable storyboards in a variety of formats. You can choose 3:4 or 16:9 aspect ratios, and have anywhere from 1 to 9 frames per sheet. And best of all, it is completely free.
