This blog post will be making a tutorial on how to change video size in Blogger post. It was tricky for me as well when I first try to figure out the process of changing the size of the video I would upload on my blog. Once you figured out how the process is, it works like a charm and easy to customize.
That being said, in the new interface you easily change the video size by clicking once on the video. You can expand or contract to your preferred size
FIRST, Go to your blogger blog and as you will be aware of how to make a new post or publish new content. The process is the same as whenever you want to publish or post new content in your blogger blog
SECOND, create a post and upload a YouTube video.
After you upload your video, click on the video and you will be able to see points on the video and use them to resize the video
