The format is simple; the layout is the hard part

A 1280 x 720 canvas gives you enough detail for YouTube while keeping the 16:9 shape. The important design work is keeping the subject and text readable when the thumbnail is displayed small.

Practical thumbnail layout rules

Use the canvas intentionally. Put the main subject in a clear focal zone, keep text short, and avoid placing important detail near the edges.

Use one dominant face, object, or moment
Keep text to three to five words when possible
