# Messaging app link preview

WhatsApp, iMessage, Slack and Discord build link previews from the page you link to. None of them publishes an image size, so we recommend the universal image: 1.91:1 at 1200 x 630 pixels.

Platform: Open Graph. Ratio: 1.91:1. Size: 1200 x 630 pixels. These are Avola Media's own recommendations, not platform specifications.

## Specification

| Item | Value |
| --- | --- |
| Recommended | 1200 x 630 pixels |
| Minimum | Not published |
| Safe zone | About 1080 x 510 pixels |
| Shown as | Each app builds its own card |
| File size | Not published |

## Notes

- Slack says it reads Open Graph and X Card tags. We expect WhatsApp, iMessage and Discord to use the same tags.
- We have not measured how these apps crop the image, so we use the universal image and its 60 pixel margin. If a client needs exact crops for one of them, we measure it.

## Exact areas

All positions are in pixels from the top left corner of the 1200 x 630 pixel frame. A picture that overlaps an edge can have its centre outside the frame.

- Safe zone edge: the SVG path "M60 60H1140V570H60Z", which spans x 60, y 60, 1080 x 510 pixels.
