## What the team makes for Instagram

### Posts in the portrait size

Every designed post is drawn in portrait 4:5 for the feed, with a square and a story size beside it, so nothing is cropped badly.

### Captions written for Instagram

The hook first, then three to six short lines. When the next step is on your website, the caption says “Link in bio.”

### Carousels with alt text

Each slide gets its own alt text, “Slide 2 of 5: …”, so people who use screen readers follow the story too.

### Reels with a voice-over

Reels are made in 9:16 with music, captions and a voice-over, from your own pictures.

## Instagram's rules, as the team follows them

The same rules the app checks before a post can be approved.

| Rule | Instagram |
| --- | --- |
| Caption | Up to 2,200 characters |
| Before “more” | About the first 125 characters show |
| Hashtags | At most 5, specific to the post |
| Emoji | 2 at most |
| Feed size | portrait 4:5 (1080 × 1350) |
| Stories | The story 9:16 (1080 × 1920) size goes out as a story |
| Posts carry | pictures, videos |
| Carousels | Yes |
| Text-only posts | No: every post has a picture or video |

Posting straight to your accounts is coming soon. Until then, download each post in its sizes with its caption.

## From your website to the feed

1. **Paste your website**: The team reads your public pages: your logo, colours, fonts, voice and the facts you confirm.
2. **The team makes the week**: It plans the posts, writes a caption for Instagram, designs each one in its sizes and checks every claim.
3. **You approve**: Approve with one tap, ask for a change, or disapprove. Nothing goes out without your yes.

## Questions

### What size does it make Instagram posts?

Portrait 4:5 (1080 × 1350) for the feed, with a square 1:1 and a 9:16 story size of the same design. The story size goes out as a story, never cropped into the feed.

### Does it write the Instagram caption too?

Yes. Each network gets its own caption. On Instagram it opens with the hook, keeps to three to six short lines, adds a few specific hashtags and says “Link in bio.” when the next step is on your website.
