What works in a kids thumbnail
- Tell it without words. The toy, cake, pet or trick has to be big. Text comes second.
- Bright, happy colors. Colorful backgrounds, rainbows, confetti and soft light. Avoid dark or scary tones.
- Happy and surprised faces. Joy and amazement work well, without exaggeration that could scare.
- Recurring characters. Use the same characters and mascots in every video to build recognition.
- Safety first. Follow YouTube’s rules for kids content and never use misleading images to attract children.
