Frequently Asked Questions
Can you set a custom thumbnail on YouTube Shorts?
Yes — upload from desktop YouTube Studio and you can select or upload a thumbnail on the video details page before publishing. Mobile uploads let you pick a frame.
What size is a Shorts thumbnail?
1080×1920 (9:16). This maker generates natively vertical so nothing gets cropped on the Shorts shelf or channel grid.
Do Shorts thumbnails actually matter?
Yes — outside the Shorts feed itself, your cover is what appears in search results, suggested videos, and your channel’s Shorts tab. Those are real discovery surfaces.
Where should text go?
Upper two-thirds. The bottom strip gets overlaid by the title and Shorts UI in most surfaces.
Can I reuse my long-form thumbnail style?
Yes — paste your channel’s video link as a style reference and the maker applies the same visual recipe vertically.
How many free covers do I get?
10 welcome credits on signup, plus 10 bonus credits after your first generation — about 10 covers free, no card needed.
Is this affiliated with YouTube?
No — Thumbcanvas is an independent tool that outputs images in YouTube’s recommended dimensions.
