An Instagram feed post shows at 1080 by 1440 for portrait, a 3:4 ratio, or 1080 by 1080 for square, and the caption is cut off after about 125 characters behind a more link. PostDecks renders that exact layout, so you can drop in your image and caption and see how the post looks in the feed before you publish.
| Image size | 1080 × 1440 (portrait) or 1080 × 1080 (square) |
|---|---|
| Aspect ratio | 3:4 portrait or 1:1 square |
| Caption limit | 2,200 characters |
| Caption cut-off | About 125 characters, then a more link |
| Carousel | Up to 10 images |
Use the aspect control to check portrait against square, then export a PDF or PNG to share with a client for sign-off. Everything runs in your browser, so your images are never uploaded.
