Free Thumbnail Text Checker
Thumbnail text has one job: be readable at a glance on a phone screen. This free thumbnail text checker analyzes your text live as you type — scoring word count, character count, ALL-CAPS usage, emoji count, and question-mark/exclamation balance against what actually earns clicks.
The golden rule is simple: 5 words or fewer, 30 characters or fewer, no shouting. Type your thumbnail text below and watch the checks update in real time, then use the tips to polish it before you export your design.
Analysis updates live as you type.
How to use

- Adjust your wording until every check shows PASS — or at worst a warning you’re comfortable with.
- Apply the tips below, then export your thumbnail at 1280×720.
Thumbnail text tips
- Complement the title, don’t repeat it. The thumbnail and title appear together — use the text for the hook and the title for the context.
- Use big, bold, high-contrast type. Your text must be readable on a phone at arm’s length; test it at 10% zoom.
- Lead with the emotional word. “WRONG about money” beats “My thoughts on money” because the feeling lands first.
- Skip the logo and the episode number. Nobody clicks for those — every pixel should sell the click.
- Test two versions. Small wording changes (“I tried” vs “Testing”) can move CTR by whole percentage points.
Frequently asked questions
How many words should thumbnail text have?
Five or fewer. Most viewers glance at a thumbnail for a fraction of a second, and short text gets read while long text gets skipped. This checker flags anything over 5 words.
Is ALL CAPS bad for thumbnails?
Full ALL-CAPS text can feel like shouting and is harder to read at small sizes. Selective caps on one key word (like “FREE” or “NEW”) can work — but whole-line caps usually underperform title case.
Should I use emojis in thumbnail text?
One emoji can add personality, but two or more tend to clutter the design and shrink the readable area. This checker warns when you pass one.
Is my text sent to a server?
No. The analysis runs entirely in your browser with JavaScript as you type. Nothing ever leaves your device.
