Quick summary
The YouTube screen size can appear too large or too small due to fullscreen mode, theater mode, or a misconfigured browser zoom level. This guide walks you through every fix to restore the YouTube player to its normal default size.
Steps
- Go to youtube.com and open any video that has a player size issue.
- If the video is in fullscreen, press Esc or click the Fullscreen (F) button at the bottom-right of the player to return to normal view.
- If the video is in theater mode, click the Theater mode (T) button to switch back to the default player size.
- If the player still looks too large or too small, reset your browser zoom using Ctrl + 0 (Windows) or Cmd + 0 (Mac).
- If the issue continues, open your browser menu, go to Zoom, manually set it to 100%, then reload the page to confirm the video player returns to its normal size.
