Opening slide: the carousel cover decides everything, and it is seen twice

This is the particularity that changes the design and almost nobody considers.

In the feed, the cover appears large, and that is where it has to stop the thumb and promise enough for the first swipe.

In the profile grid, the same image appears tiny, next to dozens of others. There it has to be recognisable and legible at a few centimetres.

The practical consequence: small text kills a cover in the grid. A three line title that works in the feed becomes a grey smudge on the profile, and the profile is where someone decides to follow.

The ruler that solves it: shrink the cover to thumbnail size and check whether the main idea is still readable.

The cover is a visual headline, and the same rule applies: specific beats vague.

• Promise something concrete. "5 bio mistakes that make visitors leave" beats "profile tips".
• Use a number when there is one. Numbers communicate scope and lower the perceived cost of swiping.
• Name the audience. When the carousel is for a segment, saying so on the cover raises relevance for the people who matter.
• Create tension, not mystery. Curiosity the content delivers works; a riddle with no answer burns trust.

A short sentence set large usually returns more than a complete sentence set small. If it does not fit large, the text is too long.

• High contrast. Light text on dark background or the reverse. Text over an untreated photo is the most common mistake and the easiest to fix with a dark layer underneath.
• One idea per cover. Two competing messages split attention and neither wins.
• Visual consistency. If all your covers share colour and typography, the profile becomes recognisable from a distance.
• Margin around the text. Text glued to the edge looks amateur and is sometimes cropped depending on where it is displayed.

• A beautiful, empty cover. Elegant design with no promise makes nobody swipe.
• A generic title. "You need to know this" does not say what it is, and the cost of swiping blind is too high.
• Text that runs too long. If it needs careful reading, the person already scrolled past.
• "Swipe" as the main message. An instruction is not a reason. What drives the swipe is the promise, not the request.
• Leaving the cover for last. Building ten slides and improvising the cover at the end is the wrong order: the cover decides whether the rest gets seen.

• The main idea is legible as a thumbnail.
• The promise is specific rather than generic.
• There is only one idea on the cover.
• Contrast is high enough.
• I wrote the cover before building the rest.
