How Long Should a Facebook Reel Be in 2026

As of 2026, there is no maximum length for an organic Facebook Reel. Meta merged all Facebook video into the Reels format in June 2025, and the old 90 second Reels cap that used to apply to every video went away with it. You can post a 15 second clip or a 20 minute one and both will publish as a Reel. The 90 second limit still exists, but only for paid Reels ad placements, not for what you post organically.

Facebook Reel Length at a Glance

Reel Type	Length Limit	Recommended Aspect Ratio
Organic Reel, any account	No cap since June 2025	9:16, 1080x1920
Paid Reels ad placement	90 seconds max	9:16, 1080x1920 (1440x2560 recommended)
In stream video ads during Reels	Truncates around 15 seconds, skippable after 5	Depends on placement

Why the 90 Second Number Still Shows Up Everywhere

Most articles and guides you'll find still quote 90 seconds as the Facebook Reels limit, because that was the rule for years before the 2025 merge, and it's still accurate on the ad side of the platform. If you're running a paid Reels ad campaign, 90 seconds is a real hard cap you need to design around. If you're posting organically from a personal profile or Page, that number no longer applies to you.

So How Long Should You Actually Make It

Just because there's no cap doesn't mean longer performs better. Reels are still a fast scrolling, vertical video format, and the platform is still built around quick hooks and short watch sessions. A safe range for most organic Reels is somewhere between 15 and 60 seconds unless you have a specific reason to go longer, like a tutorial or a highlight reel that needs the extra time to land. Going long only works if every second earns the next one. A slow start loses viewers at minute one just as fast whether the video is 90 seconds or 20 minutes, because the audience that never gets hooked in the first few seconds never sees the rest either way.

Caveats Worth Knowing

• The no cap rule describes what Facebook lets you upload and publish, not what performs well. Treat "no limit" as a technical ceiling, not a target.
• File size and format limits still apply regardless of duration. Facebook recommends MP4 or MOV with the H.264 codec.
• If you plan to repurpose a clip as a paid ad later, keep a version under 90 seconds ready to go so you're not re-editing when you decide to boost it.

Posting Reels Without Guessing on Length

If you're cross posting the same video to Facebook and other platforms with different length rules, it helps to check each platform's counter before you publish. Posted Once's Facebook character counter checks your caption length, and the Facebook scheduler lets you queue Reels alongside your other platforms from one dashboard. Pair that with the best time to post tool so length isn't the only variable you're guessing at.
