Bug - HubSpot Doesn't Allow Uploading Instagram Posts in 4:5 Format

Although HubSpot’s social media tool claims to support Instagram’s 4:5 aspect ratio (e.g., 1080x1350px), users consistently receive an error message stating that the image does not meet Instagram’s requirements.

The error message itself suggests that ratios between 1.91:1 and 4:5 are supported, yet when uploading a correctly formatted 4:5 image, HubSpot still rejects it.

This issue prevents users from scheduling standard Instagram feed posts in the recommended 4:5 format, forcing them to either crop the image to a square (1080x1080px) or manually post outside of HubSpot.

Issue Details:

  • HubSpot’s error message states that 4:5 is supported, but uploads in this format fail.
  • The issue occurs even when the image meets Instagram’s official resolution requirements (1080x1350px).
  • Other tools and direct Instagram uploads accept the same images without issue.

Suggested Fix:

  • Ensure that Instagram posts with a 4:5 ratio (1080x1350px) can be successfully uploaded through HubSpot.
  • Verify that the image validation system in HubSpot’s social publishing tool correctly recognizes 4:5 images as valid.

Why This Matters:

  • 4:5 is Instagram’s preferred format for feed posts, improving visibility and engagement.
  • HubSpot users rely on the platform for social media management, and this issue disrupts workflow and scheduling.
  • If HubSpot claims to support 4:5, it should function correctly without unnecessary errors.

Next Steps:

Can the HubSpot product team investigate and resolve this issue? If this is a known bug, when can we expect a fix? Would love to hear updates from the community and developers.

so weird that this is still a problem in july 2025.

I’m having to post using my personal phone because Hubspot won’t accept the story size image. Please fix as soon as possible.

This is still a problem for the account I manage. Does anyone know an ETA for the fix?

Yes we are still experiencing the same problem with Instagram. @hubspot when will this be fixed? Please advise…
