WordPress shortcode for group videos on WordPress Tutorials can I shorten the video group size?

Hello Support,
Ive put the WordPress videos on my website at getfoundbydesign.com and I'm wondering is there anyway i can shorten the video sizes so they don't run on into the sidebar content?
Thank you,
