Social Media Video Length Limits: 2026 Reference
·11 min read
Social media video length limits range from 140 seconds for a standard X account to 12 hours for a verified YouTube account. That range is only the beginning. The allowed duration can also change by account, device, post format, and whether you publish natively or through a scheduler.
This reference separates hard upload ceilings from “ideal length” advice. A maximum tells you whether a platform can accept the file. It does not predict watch time, reach, or engagement. Every row below was checked against first-party documentation on July 30, 2026.
If you are preparing one campaign for several networks, keep a full master and export destination-specific cuts. The practical social media scheduling guide shows how those versions fit into one publishing workflow.
Video length limits by social media platform
| Platform | Current maximum | What changes the limit | File boundary | First-party check |
|---|---|---|---|---|
| 240 minutes | Meta is moving all Facebook video posts into Reels. During the rollout, some reel composers may still show older, shorter controls. | 4 GB | Facebook video help | |
| 20 minutes | Reels longer than 3 minutes can be posted, but Instagram says they will not be recommended to new audiences. | Check the current composer | Instagram Reels help | |
| X | 140 seconds without Premium | Premium allows up to 4 hours on the web and iOS, but up to 10 minutes on Android. | 512 MB standard; 16 GB for longer Premium uploads | X longer-video help |
| YouTube | 15 minutes by default | Verified accounts can upload longer videos, up to 12 hours or 256 GB, whichever limit is reached first. | 256 GB | YouTube upload help |
| TikTok | 3 minutes for all creators | Some accounts can post 5- or 10-minute videos. TikTok tells publishing tools to read the creator-specific limit before upload. | 4 GB through the Content Posting API | TikTok media transfer guide |
| 15 minutes | The minimum is 3 seconds on desktop and 2 seconds in the mobile app. Page-specific surfaces may show different controls. | 5 GB | LinkedIn video help | |
| Threads | 5 minutes | Posts shared to the fediverse can be affected by the receiving server’s own media rules. | Check the current composer or publisher | Meta’s Threads introduction |
| Bluesky | 3 minutes | Bluesky-hosted accounts must verify their email before uploading video and can also face daily upload limits. | Check the current composer or video service | Bluesky’s 3-minute video update |
Treat the table as a dated preflight reference, not a permanent promise. Platform rollouts can make two accounts show different controls on the same day.
What each platform limit means in practice
Facebook: the video-to-Reels transition matters
Facebook's current upload help lists a 240-minute and 4 GB ceiling for video. The same help center says Facebook is moving all video posts into Reels and that Reels can be any length or orientation after the change reaches an account. Older composer help still describes 90-second reels, so use the control shown on the Page or profile you are publishing from.
Instagram: maximum length and recommendation eligibility differ
Instagram allows Reels up to 20 minutes, but its help page says Reels over 3 minutes will not be recommended to new audiences. The first number is an upload limit. The second is a distribution rule. Neither tells you the ideal duration for your own audience.
X: subscription and device create three different ceilings
A standard X account can upload 140-second videos. Premium expands that to 4 hours on the web and iOS, while the Premium Android path is limited to 10 minutes. A file that works in the desktop composer can therefore fail on the same account's Android app.
YouTube: verification unlocks long-form uploads
YouTube starts accounts at 15 minutes. Phone verification unlocks longer uploads, with a final ceiling of 12 hours or 256 GB, whichever comes first. YouTube notes that channel strikes can remove access to longer uploads even after verification.
TikTok: the creator-specific allowance is the source of truth
TikTok's developer guidance guarantees 3-minute posting for creators and says some accounts receive 5- or 10-minute limits. The Content Posting API accepts a developer-sent video up to 10 minutes, but the creator may still need to trim it to the allowance on that account.
LinkedIn, Threads, and Bluesky have simpler public ceilings
LinkedIn member uploads run up to 15 minutes and 5 GB. Threads lists a 5-minute maximum, while Bluesky expanded video posts to 3 minutes. Threads posts sent to the fediverse can meet additional server rules, and Bluesky requires a verified email before video upload.
Build a reusable export set instead of one compromised file
One universal export sounds efficient, but it makes the strictest destination decide the story for every network. Preserve the master, then create only the cuts your distribution plan needs.
Original duration
Keep the full master
Preserve the complete edit before making any social cut. Use it for long-form destinations or future re-exports.
90 seconds or less
Make a short-form cut
A practical working cut for stricter short-form composers. This is a portability choice, not an engagement promise.
140 seconds or less
Make a standard X cut
Fits the standard X ceiling while preserving more context than the shortest version.
3 minutes or less
Make a 3-minute cut
Fits the baseline TikTok allowance and the current Bluesky maximum, but not every other account or format.
These are operational export tiers, not “best length” recommendations. Your format, source material, audience, and publishing goal should decide which cuts you actually make.
Why a scheduler can show a shorter limit
A social network's native maximum does not automatically become a third-party publishing maximum. Approved tools publish through platform APIs, and those APIs can enforce different file sizes, durations, media types, account permissions, or processing steps.
TikTok documents this directly: a publishing tool can send a video up to 10 minutes, but it must also retrieve the creator-specific duration allowance. The same principle applies elsewhere. If a scheduler rejects a file that the native app accepts, use the scheduler's displayed validation instead of assuming the tool is reading the public consumer limit.
Dimensions and duration are separate checks. Use the social media image and video size guides for destination dimensions, then use the free image resizer when a visual asset needs a different crop. Video compression, trimming, and transcoding still belong in a video editor.
Check these six things before scheduling
Check 1
Format
Confirm whether the destination treats the upload as a reel, feed video, short, story, or standard post.
Check 2
Account allowance
Check the limit shown for the actual account. Verification, subscription, region, and rollout status can change the ceiling.
Check 3
Publishing path
Native apps and approved schedulers can expose different limits. Trust the validation in the path you will use.
Check 4
File boundary
Duration is only one gate. Check file size, codec, resolution, frame rate, and processing requirements too.
Check 5
Crop and safe area
Preview the destination version so captions, faces, and calls to action are not covered or cropped.
Check 6
Saved result
After scheduling, reopen the queue item and verify the account, media, duration, publication time, and processing state.
The reliable answer is the one shown at upload
Use this table to plan exports, then confirm the final number in the account and publishing path you will actually use. Keep the master, label each destination cut clearly, and verify the saved queue item after upload.
That small check prevents the most common mismatch: preparing a video to a public platform maximum, then discovering that the chosen format, account, device, or scheduler has a different ceiling.
