Publishing preset

Scores are estimated from common platform guidelines and practical publishing heuristics.

Choose a preset, upload an image and the results will appear here with score, warnings, practical recommendations and export tools.

Post guidance

Common feed ratios include square 1:1, portrait 4:5 and landscape around 1.91:1.

A dedicated export helps protect the subject from unexpected cropping and keeps the feed image intentional.

Story guidance

Stories commonly use a 9:16 vertical frame such as 1080 x 1920 pixels. Keep important details away from interface areas.

Vertical images should leave enough breathing room for captions, controls and profile UI.

Ratio reminders

A matching ratio helps reduce unexpected cropping and makes the final image feel more intentional.

The checker gives ratio guidance, but final crop choices should still be reviewed in the publishing app.

Instagram export workflow

Prepare separate exports for feed, portrait and story formats

Instagram images are often reused across different placements, but a square post, a portrait feed image and a vertical story do not share the same visual space. A dedicated export helps protect the focal point, reduce awkward crops and keep text readable on mobile screens.

PlacementCommon sizePractical note
Square feed post1080 x 1080 pxGood for product grids and balanced compositions.
Portrait feed post1080 x 1350 pxOften gives more vertical space in the feed.
Landscape post1080 x 566 pxUseful for wide scenes, but text can become small.
Story or Reel cover1080 x 1920 pxKeep important details away from UI areas.

Instagram export checklist

  • Create a separate export for feed and story placements.
  • Keep faces, products and key text away from the extreme edges.
  • Review the image on a phone-sized screen before publishing.
  • Compress the final export without blurring text or product details.
  • Verify the final upload in Instagram because the app can still recompress media.
