# Instagram media guidelines

> See the video and image limits that OpenPMM applies to Instagram Destinations.

An Instagram Post always needs media. Set `placement` in
`destination_options.instagram`. Read [Media guidelines](/docs/media/overview) for
the general rules.

## Media per post

| Type    | Media             |
| ------- | ----------------- |
| `post`  | 1 to 10 images    |
| `reel`  | Exactly one video |
| `story` | Exactly one asset |

A post and a Story accept an image. A Reel accepts a video.

## Video limits

| Property          | Limit                                                             |
| ----------------- | ----------------------------------------------------------------- |
| Container         | MP4 or MOV                                                        |
| Video codec       | H.264 or HEVC                                                     |
| Duration          | 3 seconds to 15 minutes                                           |
| Frame rate        | 23 to 60 fps                                                      |
| Width             | 1,920 px maximum                                                  |
| Video bitrate     | 25 Mbps maximum                                                   |
| File size         | 500 MiB. Instagram permits 1 GiB, but the OpenPMM limit is lower. |
| Audio codec       | AAC                                                               |
| Audio sample rate | 48 kHz maximum                                                    |
| Audio channels    | Mono or stereo                                                    |

Instagram recommends a 9:16 vertical video. OpenPMM gives advice for a different aspect ratio, but it does not block the post.

## Image limits

| Property     | Limit                                                    |
| ------------ | -------------------------------------------------------- |
| Format       | JPEG. Instagram accepts no other image format.           |
| File size    | 8 MB maximum                                             |
| Aspect ratio | 4:5 to 1.91:1 for a post and for a carousel              |
| Width        | Instagram scales an image to between 320 px and 1,440 px |
| Colour space | Instagram converts an image to sRGB                      |

OpenPMM converts a PNG or a WebP image to JPEG for you, and makes the file
smaller when it is above 8 MB. See [Media compatibility](/docs/guides/media-compatibility).

An aspect ratio outside the 4:5 to 1.91:1 range needs a crop or a pad. OpenPMM
does not do this for you, because it changes what the image shows. Use another
file, or remove the destination.

A Story has no aspect ratio limit. Instagram recommends 9:16 to prevent a crop
or a blank space.

Instagram crops every image in a carousel to match the first image. The default
is 1:1.
