Table of contents
Many people start with a template and end up with something busy but unclear. A cover exists to win one tap in a feed, and the only test is whether it can still be read at thumbnail size on a phone.
1. One Cover Answers One Question
Each cover answers what the video is about. Answer that and the click rate follows; fail and no amount of polish helps.
Cover text is therefore a distillation of the title, not a copy of it. The title can be long; the cover should carry six to ten characters.
2. Three Information Layers
Layer one is the subject: a person, product or scene occupying at least sixty percent of the frame. Layer two is text: one conclusion or one number. Layer three is auxiliary: brand mark, series number.
The layers diminish in importance. If the subject is unclear, bigger text will not save it; if the text is long, the auxiliary layer gets pushed out.
3. A Three-Element Checklist
| Element | Standard | Common problem |
|---|---|---|
| Subject | Over 60% of frame, clean edges | Too small, cluttered background |
| Text | 6–10 characters, width about one third | Too many characters, thin fonts |
| Contrast | Clear light-dark separation | Light text on light background |
| Safe area | Key content away from edges | Covered by platform badges |
| Consistency | Same layout across a series | New style every video |
Keep the checklist beside your workspace and run it after each cover; it saves more time than repeated edits.
4. The Mobile Readability Test
Shrink the frame to a quarter size in the editor. If the text is unreadable, it is too small.
Another method is to squint: if you can still make out the subject and the text position, the hierarchy works; if it blurs into one mass, contrast is insufficient.
5. Making a Cover Attractive
Attraction comes from specificity, not exaggeration. "Three quoting structures compared" beats "must-watch tips" because it promises definite information.
Facial expressions, mid-action frames and real usage scenes pull more than posed stills. A frame lifted from the video often looks more natural than a separate shoot.
6. Producing in Batches
Build a master template: fixed background, fixed type size, fixed text position. Then each cover only swaps the subject image and the text, taking about ten minutes.
Ten at a time is far faster than one at a time. Export in one batch and name files by date and sequence, so you can later see which cover earned the clicks.
7. Covers and Subtitles
Cover text and subtitles are different jobs. Cover text should be large and short; subtitles should be complete and accurate. For subtitle style, keep it fixed: moderate size, clear outline, positioned away from the bottom controls.
Keep subtitle styling consistent across an account so viewers recognise your content at a glance. Frequent changes weaken recognition.
8. FAQ
Does a cover need text?
Not always. A distinctive subject can carry a text-free cover, but the image itself must hold information.
Can one cover serve several videos?
Not advisable. Repeated covers make viewers think they have seen it and scroll past.
What size should the cover be?
Match each platform's vertical ratio and check nothing is cropped. Save one version per platform rather than reusing a single file.
How do we judge a cover?
Look at click rate combined with completion rate. High clicks and low completion mean the cover overpromised; both low means it missed the audience.
