Instagram Feed Preview in Light & Dark Mode

The feed is where a post gets its longest look. Preview your image, profile row, engagement, and caption exactly as they stack in an Instagram feed card — in both light and dark mode — before you publish.

Use the Full 4:5 Height

The feed allows up to a 4:5 portrait (1080×1350), the tallest single-image format and the one that fills the most screen. Square 1:1 and landscape 1.91:1 render here too; switch ratios to see how much vertical space each claims as someone scrolls.

Catch the Caption Fold

Instagram collapses captions after roughly the first two lines — about 125 characters — behind a “more” link. Toggle the collapsed and expanded states so your hook, offer, or key line survives above the fold.

Test Light and Dark Cards

The same photo reads differently on a white card than on a near-black one. Flip the feed preview between light and dark mode to check contrast, borders, and how a light or transparent background behaves.

Frequently Asked Questions

About This Feed Post Simulator

How do I preview an Instagram feed post before posting?

Upload your image above and the tool renders a full feed card — avatar, username, actions, and caption — with no login or Instagram connection. The fictional profile fields are for presentation testing only.

How tall can a feed post be?

The tallest single image the feed accepts is 4:5 portrait, about 1080×1350 pixels. Anything taller is cropped toward that ratio, so preview a 4:5 upload to use the maximum feed height.

Can I expand the caption in the feed preview?

Yes. Switch between the collapsed “more” state and the fully expanded caption to see both what a scroller notices first and the complete text.
