Best Practices
Tips for Making Great Thumbnails
Always start at platform size instead of resizing later. Resizing causes quality loss. Design at final dimensions from beginning.
Test thumbnails at actual display sizes. Platforms show thumbnails at various sizes. Verify readability at smallest mobile size.
Keep file size under platform limits. YouTube allows 2MB, check other platforms. Compress without losing quality.
Design for smallest display first. If thumbnail works on phones, it works everywhere. Mobile-first design ensures universal readability.
Export multiple resolution versions. Provide 1080p for normal, 2K for high-res screens. Multiple exports cover all devices.
Check aspect ratio stays locked. Changing ratios creates stretched images. Always maintain platform-required aspect ratio.
Common Mistakes
What to Avoid
Designing at wrong size then resizing. Resizing degrades quality and changes how text looks. Always design at final size.
Ignoring file size limits. Large files get rejected by platforms. Optimize file size while maintaining visual quality.
Not testing mobile size. Thumbnail perfect on desktop fails on phones. Always preview at actual mobile display size.
Using vertical or square images. Platforms need horizontal 16:9 format. Wrong aspect ratio causes rejection or poor display.
Forgetting platform has minimum size. Too small causes pixelation. Meet minimum dimension requirements for quality.
Exporting in wrong file format. Some platforms prefer JPG, others PNG. Check platform requirements for format.
