What makes a great thumbnail?

Great thumbnails nail five things - here's what our AI looks for when generating yours.

Contrast

High contrast between text and background makes your thumbnail readable even at small sizes in search results.

BeforeLight text on a bright background

AfterBold white text on a dark overlay

Use dark backgrounds with bright text or vice versa.

Emotion

Thumbnails with expressive faces get significantly more clicks. Viewers connect with human emotion before reading text.

BeforeA neutral face looking at the camera

AfterAn exaggerated shocked or excited expression

Exaggerate your expression — subtle doesn't work at 120px.

Text

Keep thumbnail text to 3–5 words max. It should add context the image alone can't convey.

If the image tells the story, you may not need text at all.

Color

Consistent brand colors make your videos instantly recognizable in a sea of recommended content.

BeforeRandom colors on every thumbnail

AfterA signature color palette across all videos

Pick 2–3 brand colors and use them consistently.

Composition

A clean focal point with minimal clutter guides the viewer's eye. One subject, one message.

BeforeCluttered image with multiple objects

AfterSingle subject with clean background and bold text

Remove anything that doesn't support the main message.
