One face, one idea
Top-performing thumbnails feature a single large expression. Multi-photo collages must still crown one dominant reaction frame.

FAQ
YouTube Thumbnail Collage Questions
What size must YouTube thumbnails be?
1280×720 pixels (16:9), under 2 MB. Both conditions are met by composing on the landscape canvas and exporting JPEG.
Do multi-photo thumbnails hurt click-through?
Not if hierarchy is strict — one dominant expression supported by smaller context cells. Equality kills CTR; dominance drives it.
How do I test thumbnail legibility?
Zoom your browser out until the canvas renders around 170px wide. If the story and faces still read, the thumbnail works in real sidebar conditions.
Can I reuse one collage across several videos?
Possible but unwise — fresh thumbnails signal fresh content. Swap two cells and regrade for a fast variant instead.
Is the thumbnail collage maker free?
Yes — free exports, no watermark, unlimited attempts at the perfect CTR weapon.
