Prompt template
In Pikzels (or Canva for template-driven approach):

1. Paste your YouTube URL OR upload your video
2. Pikzels analyzes content + extracts key moments
3. Choose a template style or generate from scratch

For best CTR, your thumbnail should:
- Show ONE clear focal point (your face, the result, the question)
- Include 3-5 words MAX of bold text
- Use high contrast colors (red/yellow/blue, not muted)
- Show emotion in faces (surprise, curiosity, achievement)
- Avoid stock photo aesthetics

Template prompts that work:
- "[YOUR FACE] reacting to [SUBJECT], with bold text [HOOK PHRASE]"
- "Split screen: [BEFORE] vs [AFTER] with arrow"
- "Number-based: '7 lessons from [TOPIC]' with iconic visual"

Always generate 3-4 variations and A/B test in YouTube Studio after upload.

Frequently asked

  • What dimensions should a YouTube thumbnail be?

    1280x720 pixels (16:9 aspect ratio), under 2MB, JPG/PNG/GIF. Most thumbnails are viewed at much smaller sizes (320x180 in suggested videos), so design for legibility at thumbnail size first.

  • How do I write text that's readable on small thumbnails?

    Maximum 3-5 words. Bold, sans-serif fonts. White text with black outline OR black text with yellow background — both have highest contrast. Avoid thin fonts, scripts, and small caps. Test by viewing the thumbnail at 320x180 size before publishing.

  • Should I use my face in every thumbnail?

    For most niches, yes — face thumbnails get higher CTR because humans pay attention to other humans. Exceptions: tech tutorials (show the result), gaming (show gameplay), data/explainer content (show the chart). A/B test both approaches in YouTube Studio.
