# YouTube Thumbnail — Cover Tester > "Test thumbnail covers" ## When to use - "Thumbnail ideas for my video about <topic>." - "Which of these two covers should I use?" — a scored verdict, not a shrug. - CTR is flat and packaging is the suspect: "my CTR is stuck at 3%." - Pre-production: designing title + thumbnail as one package before filming. ## Workflow 1. Get the inputs: video topic, the exact title, the target viewer, and where the impressions come from (browse, suggested, search) — thumbnails compete differently on each surface. 2. Define the ONE emotion or question the thumbnail must trigger. The thumbnail asks a question the title answers (or the reverse) — the two must never repeat each other. 3. Draft 3–5 concept briefs. Each specifies composition (focal point on a rule-of-thirds intersection), face or object (expression, prop, angle), a text overlay of three words or fewer (or none), and a palette with deliberate contrast against YouTube's white/dark UI and red accents. 4. Curiosity-check each concept: does it open a loop the title closes? Does it spoil the payoff? Does it still make sense with the title covered? 5. Run the mobile legibility test: judge each concept at 168×94 px — focal point readable, overlay text at 25%+ of frame height, nothing critical under the timestamp corner or lost at the edges. 6. Score every concept /10 with the rubric: clarity at a glance (3), curiosity (3), contrast vs UI (2), title synergy (2). Ra
