A Reel is judged twice before anyone watches it. First by the cover, which appears in your profile grid, in search and on the Reels tab. Then by the first frame and the first seconds, which decide whether the viewer stays or swipes up. Many small businesses film a decent video and then lose it on a random cover and a slow start. This guide covers the right cover size, the safe zones and a practical way to design the first frame and the opening seconds, for Instagram Reels and the same logic for YouTube Shorts and TikTok.
- Design the cover vertically at 1080 × 1920 px (9:16) and keep the key text and face in the center, because the profile grid and other previews crop the edges.
- The cover is for people browsing your profile; the first frame and the first 1–3 seconds are for people in the feed. Treat them as two separate jobs.
- Open with the result, the problem or the question, not with a logo or “Hi, my name is…”.
- Keep covers in one visual style so the profile grid looks like a catalogue of videos.
1. Cover and first frame: what is the difference
These are not the same thing, and mixing them up is the most common mistake.
| Cover | First frame | |
|---|---|---|
| Where people see it | Profile grid, search, the Reels tab, shared links | In the full-screen feed at the moment the Reel starts to play |
| Job | Make a browsing person want to tap, and explain the topic | Make a scrolling person stop in a second |
| Form | A still image with a short headline, or a frame from the video | The first moving image, usually with a large on-screen line |
| Where you set it | In the publishing screen, “cover” step | In the video editor, at the very start |
2. Reels cover size and format
A Reel is a vertical video. The usual recommendation is a 9:16 frame at 1080 × 1920 px. Cover images follow the same proportions. The point to remember: the places where the cover is shown do not use the same crop.
- Full-screen view shows the whole 9:16 frame.
- The profile grid shows a cropped preview, and the shape of this preview has changed over time (from square to taller rectangles). Check how your own profile looks, and keep everything important in the central area.
- The Reels tab and search show the cover with a title or view count in the corner.
Practical rule: place the headline and the face or product in the middle 60% of the height and at least 10% of the width away from the sides. If your cover looks good as a small square in the middle of the frame, it will look good everywhere.
The same ratio works for YouTube Shorts and TikTok videos, so one vertical master can serve all three; see cross-posting on how to adapt it.
3. Safe zones: where the interface covers your picture
On top of the video the app draws its own elements: the profile name and follow button at the bottom left, the caption, the audio line, the buttons for likes and comments on the right, and the progress bar. Therefore:
- keep key text away from the bottom 20–25% of the frame and from the right edge;
- leave the top 10–15% free as well, since the status bar and the header take it;
- put subtitles slightly above the bottom caption area, but not in the very center, where they hide your subject;
- review the video on your own phone in the real app before you publish; templates differ by network and change often.
4. How to choose and design a good cover
- One clear promise. A short headline of two to five words that says what the video gives: “3 ways to store coffee”, “Gel polish at home: mistakes”, “Price of a kitchen: what it consists of”.
- One main object. A face, a product or a result. Not a collage.
- Large readable text. It should be legible at the size of your thumb in the grid, so no more than six words and a heavy font.
- Contrast. Light text on a darker area or the other way round; add a soft shadow or a plain block behind the text if the background is busy.
- Same style for all covers. The same font, the same color for the headline and one recurring element make the grid look like one series. A set of templates helps; see social media design templates.
- Use a face when possible. A person’s expression often draws the eye, but do not force it if your content is about the product.
- No false promises. A cover must match what is in the video. Misleading covers bring clicks and quick exits.
You can pick a frame from the video or upload your own image. A custom cover gives you control over the headline; a frame from the video is faster. For topics people search for, a clear headline is almost always worth the extra minutes.
5. The first frame: stop the scroll
In the feed there is no cover: the video simply starts. People decide within a second or two whether to keep watching. The first frame therefore should already contain a reason to stay.
- Start in the middle of the action. Do not show the preparation: begin with the pour, the cut, the finished result.
- Put the topic on screen immediately. A large line of text in the first frame (“Do not do this with a new tablecloth”) works with the sound off, which is how many people watch.
- Movement or contrast in the frame. A static plain shot is easy to scroll past.
- Skip the intro. No logo animation, no “Hello everyone”.
- Face to camera. If a person is speaking, start with the first meaningful sentence.
6. The first three seconds: patterns that hold attention
| Pattern | Example opening | Good for |
|---|---|---|
| Result first | The finished manicure, then “here is how it is done” | Before/after, process videos |
| Question | “Why does your cake sink in the middle?” | Educational, problem solving |
| Mistake | “Stop doing this with your suede boots” | Tips, expert content |
| Number and promise | “Three things I check before every delivery” | Lists, checklists |
| Curiosity gap | “This is what is inside a 40-euro bouquet” | Products, behind the scenes |
| Direct address | “If you run a small shop, watch this” | Niche audiences |

7. A quick workflow for a cover and an opening
- Write the headline before shooting. If you cannot say in five words what the video is about, the video is not ready.
- Film the opening line twice. The first take is often the weakest; choose the more energetic.
- Edit the start tight. Cut silence, breaths and “so, today…” before the first meaningful word.
- Add on-screen text in the first second, inside the safe zone.
- Choose the cover after editing: a custom image with the headline or the strongest frame.
- Check on the phone in the grid preview: is the headline legible, centered and not cut off?
- Look at retention afterwards. If most people drop in the first seconds, change the opening, not the topic.
8. Mistakes to avoid
- A cover that is a blurred frame with random facial expression.
- Text too close to the edges, cut by the grid or hidden by interface.
- A different font and color on every cover.
- Long intros before the point.
- Clickbait that the video does not deliver.
- Covers with other apps’ watermarks.
- Forgetting that Stories and Reels share the vertical frame but not the same safe areas.
9. How to do it in AI SMM
If your Reels begin as long videos, a webinar, an interview or a YouTube video, video clipping cuts them into vertical short clips so you do not have to find the strongest 30 seconds by hand; see how that works in turning a YouTube video into Shorts. The AI content studio helps with the headline: it proposes several variants for the cover and the on-screen first line, plus a caption in your brand’s tone, and creates a branded picture if you want a custom cover. Then you schedule the Reel in the planner to Instagram, Facebook and, if you wish, other video networks. Instagram comments and messages come to the shared inbox. The cover and the first frame themselves you design and check yourself, on your phone, in the app where the video will be shown.
FAQ
What size should a Reels cover be?
Create it at 1080 × 1920 px (9:16). Keep text and the main object in the central area, because the profile grid and other previews crop the sides and parts of the top and bottom.
Can I change the cover after publishing?
Instagram allows editing the cover of a published Reel in the post’s options. The exact steps change with app updates, so check in the current version.
Should the cover have text?
For informational and how-to videos, yes: a short headline makes the topic clear in the grid. For emotional or aesthetic content a clean frame may be better. Test both and compare what your audience opens.
Is the first frame the same as the cover?
No. The cover is for browsing; the first frame is what viewers see in the feed. You can make them match, but design each for its own job.
Take your last three Reels, redesign their covers and rewrite the first three seconds, then compare the next batch. When the routine is stable, let AI SMM cut the clips and keep your time for the openings.
