Frequently Asked Questions
What size should a YouTube thumbnail be?
1280×720 pixels at 16:9, under 2 MB. YouTube requires a minimum width of 640, but uploading at 1280 keeps it sharp on televisions and full-screen players where a smaller image visibly softens.
How much text should a thumbnail carry?
Three to five words at most, very large. Most viewers see the thumbnail at the size of a postage stamp on a phone — text that reads comfortably on your monitor disappears entirely there. Shrink it to check.
What makes a thumbnail get clicked?
Contrast and a face, mostly. High contrast survives being shrunk; faces with clear expressions attract attention. Avoid clutter — a busy thumbnail becomes grey mush at small sizes.
Is my design uploaded anywhere?
No. Everything runs in your browser and there is no watermark on the export.
Does the thumbnail need to match the video?
Yes, and it is a policy matter as well as good practice. A misleading thumbnail drives clicks that leave immediately, which damages the retention signals YouTube actually rewards.

Tips for better results

- Keep important text away from the edges; platforms crop previews differently in feed and full view.
- Platform dimensions change. Re-check anything you produced more than a few months ago.
Common problems and how to fix them
The image was cropped after upload
The aspect ratio does not match what that placement uses. Pick the preset for the exact placement, not the generic platform size.
The caption was truncated
The preview limit is shorter than the posting limit. Put the essential line first.
Colours look different once posted
Platforms re-compress uploads. Avoid heavy gradients and very fine detail, which suffer most.
