YouTube Shorts Thumbnails
For YouTube Shorts, thumbnails are displayed in a 9:16 portrait format. The recommended resolution is 1080 × 1920 px. However, YouTube often auto-generates Shorts thumbnails from a frame in the video.
You can still download Shorts thumbnails using our tool — just paste the Shorts URL (e.g., youtube.com/shorts/VIDEO_ID) and grab all available resolutions.
Available Thumbnail Resolutions on YouTube
YouTube generates multiple thumbnail sizes for every video:
- maxresdefault.jpg — 1280×720 (not always available)
- sddefault.jpg — 640×480
- hqdefault.jpg — 480×360
- mqdefault.jpg — 320×180
- default.jpg — 120×90
Best Practices for YouTube Thumbnails in 2026
- Always use 1280×720 resolution for maximum clarity across devices.
- Keep file size under 2 MB — use JPG for photos, PNG for text-heavy graphics.
- Use high contrast colors and large text (3-5 words max).
- Include faces with expressive emotions — they increase CTR by up to 38%.
- Maintain brand consistency with a recognizable template.
- Test thumbnails on mobile (where most views happen) — text should be readable at small sizes.
