Mobile UI Overlay Boundaries & Safe Margins

Test your vertical video graphics and YouTube thumbnails against native mobile UI obstructions to protect titles, subtitles, and calls-to-action.

Platform Guidelines

• YouTube Shorts (9:16): Keep bottom 20% and right 20% clear of critical typography.
• Instagram Reels (9:16): Center key graphics in the middle 60% viewport to avoid caption overlay.
• YouTube Thumbnails (16:9): Avoid the bottom-right corner where video timestamps are displayed.
