Resizing video screen during playback

[sincityk9]

I was showing someone a youtube video and when I handed him the phone it changed the screen size to a much smaller one on the phone. Any help a on how to get it back to full screen size

Maybe he accidently hit the HD/SD buton in lower right-hand corner.
When in SD mode my You Tube player shows picture size of about 3/4. When I push HD it goes to fullscreen.....???
