Step-by-Step Guide
Choose Your Core Message
Pick one word that conveys video value (e.g., 'FREE', 'FAIL', 'SECRET'). Avoid generic text.
Select Font and Size
Use bold, sans-serif fonts. Test at 168x94px to verify readability before committing.
Add Contrast Layer
Place text on solid background or add shadow/outline to ensure it pops against images.
Position for Visual Flow
Place text where eyes naturally land (top-third or alongside focal face). Avoid covering key imagery.
Remove Unnecessary Words
If you're using more than 3 words, remove filler. Every word must add value.
Text Hierarchy Rules
Limit to 3 words maximum. Use one bold, large word as the primary message. Smaller text for context only. Viewers read thumbnails in 1-2 seconds.
Font Selection
Choose bold, sans-serif fonts (Arial Black, Impact, Bebas Neue). Avoid thin fonts—they're invisible at 168x94px. Ensure fonts are recognizable at small sizes.
Size and Spacing
Main text should be 15-20% of thumbnail height. Use 2px+ letter spacing for clarity. Add padding around text to prevent overlap with images.
Color and Contrast
White or black text works on most backgrounds. Add a 3-5px shadow or outline for contrast on complex images. Test legibility on mobile.
Pro Tips
- Use ALL CAPS for short words—they're faster to read and command attention.
- Add a stroke (outline) around text to work on any background color.
- Avoid Comic Sans, script fonts, and thin typography—they fail on mobile.
- Leave 10-15% padding on edges so text doesn't get cut off across devices.
- Test with colorblind viewers—ensure contrast isn't solely color-dependent.
