How this tool works

A custom Reel cover shows on your profile grid and in the Reels tab — it's often the deciding factor in whether someone taps play. This tool checks your cover image's size and shows how it will be cropped.

  1. Upload your cover image.
  2. See its exact pixel dimensions and aspect ratio.
  3. Preview the 3:4 grid crop Instagram will apply.
  4. Adjust and re-upload if key details sit outside the crop.

Tips to get better results

  • Design your cover at the full 1080×1920 canvas even though the grid only shows a 3:4 slice — you get more flexibility repositioning later.
  • Keep a consistent cover style across Reels so your profile grid reads as a cohesive series.
  • Bright, high-contrast covers stand out more against the white Instagram interface.

Frequently asked questions

What size should a Reel cover image be?

Upload at 1080×1920 pixels — the same canvas as the Reel itself — even though only a 3:4 crop shows on the grid.

Can I use a photo instead of a video frame as the cover?

Yes, Instagram lets you upload a separate image from your camera roll as the custom cover instead of selecting a frame from the video.

Why does my cover look cropped on the profile grid?

The grid displays a 3:4 portion of your 9:16 cover image, so anything near the very top or bottom edge gets trimmed from the thumbnail.
