Thumbnail test: which thumbnail gets the click?
Need a thumbnail test before you publish a cover, listing or video? A thumbnail tester can show which design people notice and why. Compare two images with 5 to 50 verified UK adults. We aim for first answers within about 15 minutes in UK daytime; replies can be slower for now. For YouTube-specific testing, see the YouTube thumbnail test.
We review requests by hand.
Questions for a thumbnail tester
Choose the placement first: a vertical Reels cover, a square podcast tile, a course thumbnail or a product-listing image. Then put two versions for that placement side by side in one image and ask a neutral question.
- Example: RoomKind compares ‘SMALL ROOM BIG CHANGE’ with ‘MAKE ROOM FEEL BIG’ for a short course cover. Which would you tap?
- Which podcast cover is easier to recognise at phone size?
- Looking at these two product images, what would you expect to receive?
A pick-one or first-impression question is available now. The thumbnail checker records one line of reasoning from each person.
What a thumbnail test returns
Illustrative RoomKind example: 14 of 20 choose B, ‘MAKE ROOM FEEL BIG’; six choose A. The example reasons say B is easier to read at small size, while A feels crowded. RoomKind can simplify the next course-cover draft. Read the reasons as well as the split: 20 opinions are a steer, not a forecast of taps, downloads or sales.
How to use a thumbnail checker
- Choose the exact placement you care about, then export both versions at its likely display size. Put them side by side in one PNG, JPEG or WebP image.
- Choose a pool of 5 to 50 UK adults and ask one question about that placement. People answer without seeing who asked or how others voted.
- Read the split, each one-line reason and the summary. If the result is close, revise one design or swap the positions and ask again.
The Ask page covers other questions. For a live video platform, YouTube thumbnail testing has its own limits and tools.
Which thumbnail is better at a glance?
A creator who designed a podcast tile or shop image knows what it is meant to say. Someone scrolling past sees it at a glance, often very small. An outside view may reveal unreadable type, an unclear subject or a visual that suggests the wrong product. A preference test tells you what this small group noticed; it does not measure platform behaviour. Each answer has a signed receipt showing the checks it passed. See how answers are checked.
Honest limit: This is a mixed group of UK adults, not your followers, subscribers or customers. A stated preference cannot predict clicks, plays or purchases on TikTok, Instagram, Etsy, Shopify or another platform. Compare versions for the same placement: mixing a podcast square with a Reels cover would confuse format with design. Left-right position can also sway a small split.
What thumbnail testing costs
Asking is free during early access. At paid launch, a quick take starts from 30p an answer plus 50p a question (launch example): 20 quick takes would come to about £6.50. You see a quote before asking.
Your questions, answered
How do I run a thumbnail test before publishing?
Pick one destination and compare two versions for that slot at realistic display size. Ask which is clearer or which a person would tap, then read the reasons as well as the count. A course cover, podcast tile and product image need different crops, so test each format on its own terms.
Is there a free thumbnail checker?
Asking on PennyForYours is free during early access, by invitation. People tell you which thumbnail they prefer and why; this is an opinion test, not an automated image score. Paid questions will have a quote before you post. There is no set date for paid launch.
Which thumbnail is better, A or B?
Use the split to see the direction, then read why people picked each design. In the illustrative RoomKind course-cover example, B wins 14 to six because its words are easier to read. A close split or mixed reasons are a reason to revise and test again, not to declare a universal winner.
How many people should rate my thumbnail?
Twenty is a useful starting pool for choosing between two designs. Five can give a quick steer; up to 50 gives you more reasons to inspect. These are small, mixed groups, so do not treat the result as a representative audience study or a prediction of taps, plays or purchases.
Can I choose people from my platform or niche?
No. The current pool is 5 to 50 verified adults in the UK without interest or follower targeting. If your cover serves a narrow audience, treat this as a clarity check from a mixed group. Compare it with the behaviour you can later see in your own platform analytics.
How much does a thumbnail test cost?
It is free to ask during early access. The paid-launch example is from 30p an answer plus 50p per question, so 20 quick takes would cost about £6.50. That is an example, and the quote shown before asking will control the actual price.
