YouTube Thumbnail Size: Complete Guide (2025)

Dimensions, aspect ratios, formats, and pro tips to design thumbnails that get clicks.

Recommended Specs (Quick Reference)

  • Resolution: 1280×720 px (minimum width: 640 px)
  • Aspect Ratio: 16:9
  • Formats: JPG, PNG, WebP
  • File Size: under 2 MB

Why 1280×720 (16:9) Works Best

Thumbnails appear small on feeds but are shown at larger sizes on high-density screens and embeds. Designing at 1280×720 keeps your artwork crisp everywhere. Always maintain the 16:9 ratio to avoid unexpected cropping.

Alternate Sizes & Safe Areas

While 1280×720 is the standard, consider safe margins so text never touches the edges. Keep critical elements away from the lower right corner where duration badges and UI may overlap.
