Thumbnail Best Practices
Use High Contrast
Make elements pop against the background. Bright colors like red and yellow attract the eye on dark themes.
Faces with Emotion
Human connection drives clicks. Use close-ups of faces with clear, exaggerated emotional expressions.
Consistent Branding
Help viewers recognize your content instantly with a signature color palette or consistent font choice.
Text Accessibility
Use large, bold fonts with 2-4 words max. Ensure readability on small mobile screens.
