Instagram Reels cover 420×654
Instagram recommends 420 × 654 (about 1:1.55) for Reels covers. This is the cover canvas, not the 9:16 video size, and the official documentation notes the cover cannot currently be edited after upload.

Framing advice
- Design the cover at 420 × 654 on its own — do not reuse the 1080 × 1920 Story canvas.
- Keep the title and subject centred, and check the actual crop in the profile grid before publishing.
- Confirm the cover before you publish; the help page states it cannot be changed afterwards.
The most common failure
Treating the 9:16 video canvas as the recommended Reels cover size, which produces a cover that frames badly in the profile grid.
