Understanding Current Instagram Reel Length Limits (2024 Update)
Instagram has gradually extended Reel durations since launch. As of mid‑2024, here’s the official progression:
| Year | Max Reel Length |
|---|---|
| 2020 | 15 seconds |
| 2021 | 30 seconds |
| 2022 | 60 seconds |
| 2023–2024 | 90 seconds |
While the maximum is now 90 seconds, many high‑performing Reels are shorter due to the platform’s algorithm and user attention spans.

Short‑Form vs Long‑Form Reels: Reach and Retention
Short‑form Reels (15–30 seconds) often outperform longer ones in pure reach:
- Quicker to watch and share.
- More likely to be replayed.
- High completion rates feed algorithmic promotion.
Long‑form Reels (60–90 seconds) offer room for richer storytelling or tutorials, but retention usually drops after 45–50 seconds unless content remains compelling.
Pro tip: In 2024, the broad‑appeal sweet spot is 20–35 seconds. Reserve longer clips for topics that need extra depth.
