The Shrinking Canvas
On a mobile phone, your thumbnail appears at roughly 160x90 pixels—smaller than most app icons.At this size:
- Small text becomes unreadable
- Fine details disappear
- Complex compositions become confusing
Mobile - First Design Principles
1. Large, Bold Elements
Everything needs to be bigger than you think.If text is included, it should be readable at thumbnail size on a phone screen.
2. High Contrast
Strong contrast between elements ensures visibility even on small screens or in bright outdoor conditions.
3. Simple Compositions
Limit your thumbnail to 1 - 2 focal points maximum.Cluttered thumbnails fail on mobile.
