Ideal Short Video Length by Platform in 2026 (TikTok, Reels, Shorts)
The actual length limits and sweet spots for TikTok, Instagram Reels, Facebook Reels, and YouTube Shorts.
Short answer
Aim for 30-90 seconds as the safe default across TikTok, Reels and Shorts. Instagram Reels hard-caps at 90 seconds, Facebook Reels are best under 60, TikTok technically allows 10 minutes but short clips win reach, and YouTube Shorts now allows up to 3 minutes if a moment genuinely needs the extra room.
Length limits and sweet spots by platform
| Platform | Max length | Sweet spot |
|---|---|---|
| TikTok | 10 minutes | Under 60s |
| Instagram Reels | 90 seconds | 30-60s |
| Facebook Reels | No hard cap | Under 60s (recommended) |
| YouTube Shorts | 3 minutes | 30-90s |
The pattern across every platform is the same: the technical maximum keeps increasing (TikTok's 10-minute ceiling, YouTube's jump from 60 seconds to 3 minutes), but the actual sweet spot for reach and completion rate has stayed short. A longer max just means you're no longer forced to butcher a good moment to fit an old 60-second limit — it doesn't mean longer clips outperform shorter ones.
Why this matters when clipping a long video
When you're cutting a clip out of a podcast, livestream, or long upload, the platform's length limit changes which moments are even usable. A 2-minute back-and-forth that makes a great point can't go on Instagram Reels at all without trimming — but it fits inside YouTube Shorts' 3-minute window intact. Picking the platform before you pick the clip saves a re-cut later.
This is also why the length limit matters more than it looks: a clip that gets cut off mid-sentence because it hit a hard platform cap has the exact same "loses context" problem as a bad AI cut — see the related post on why auto-clipped Shorts lose context for the fixes.
Cutting one clip for multiple platforms
If you want the same moment posted everywhere, cut to the tightest constraint first — usually Instagram Reels' 90-second cap — and that version will already fit TikTok and YouTube Shorts without further editing. Only cut a separate, longer version for YouTube Shorts specifically when a moment genuinely needs more than 90 seconds to land, since the 3-minute ceiling is there for exceptions, not the default.
Frequently asked questions
How long can a YouTube Short be in 2026?
Up to 3 minutes. YouTube raised the original 60-second cap, which gives you room when a clip pulled from a longer video needs a few extra seconds for the setup and payoff to both fit. Many creators still aim for 30-90 seconds since that range performs best for completion rate, but the 3-minute ceiling means you're no longer forced to cut a good moment short.
What's the maximum length for a TikTok video?
TikTok technically allows uploads up to 10 minutes, but short-form clips under 60 seconds consistently get the most reach and completion rate. If you're clipping a podcast or livestream for TikTok specifically, treat 10 minutes as a technical ceiling, not a target — most clip-worthy moments fit comfortably under a minute anyway.
How long should an Instagram Reel be?
Instagram Reels cap at 90 seconds. Unlike YouTube Shorts, there's no recent extension, so if you're repurposing the same clip across platforms, 90 seconds is your binding constraint — cut to fit Reels first, then the same clip usually fits TikTok and YouTube Shorts without further trimming.
Do I need a different length for Facebook Reels?
Facebook Reels are recommended at 60 seconds or under, though the platform accepts longer uploads. Facebook's audience and algorithm still favor shorter, tighter clips, so keeping Facebook Reels close to the TikTok sweet spot rather than stretching to the Instagram or YouTube ceiling tends to perform better.
