Instagram post preview

Drop in an image and paste your caption to see a rough mock-up of the post. Instagram Help keeps photos between 1.91:1 and 3:4 uncropped and allows up to 5 hashtags, and Meta's docs cap captions at 2,200 characters. The preview shows your counts against those limits.

How it works

  1. 1

    Drop in an image. The browser reads it, and nothing is uploaded.

  2. 2

    The preview frame matches your image's ratio, held between 1.91:1 and 3:4.

  3. 3

    Paste your caption. It's counted against 2,200 characters and 5 hashtags.

  4. 4

    Read the ratio note under the counts. It says whether the image falls outside 1.91:1 to 3:4, the range Instagram crops to.
