TikTok Video Size and Length: A Practical Specs Guide

For an ordinary full-screen TikTok, start with a 9:16 vertical canvas at 1080 × 1920 pixels. Export a standard MP4 using H.264 video and AAC audio when your editor offers those choices. This combination is widely compatible, gives the platform a clean vertical source and is easy to review on a phone before upload.

Treat that as a practical baseline rather than a statement that every other file is rejected. TikTok accepts multiple shapes and formats in different workflows, and it re-encodes uploads. Square and horizontal clips may post, but they use less of a vertical screen unless you intentionally design a background or layout around them.

Length controls, upload ceilings and format support change by app version, device, region, account and whether you record in-app, upload an existing file or create an advertisement. Check the options shown in the exact publishing flow you will use. A three-year-old specification table should not override a current validation message in your app.

Nine by sixteen matches the portrait shape of TikTok's main viewing experience. TikTok for Business also continues to recommend full-screen 9:16 creative, which is useful directional evidence even though organic posts and ads do not share every technical rule. Designing in that shape gives the picture room to feel native without automatic bars.

Do not stretch a horizontal source to fill the frame. Either crop it intentionally, place it inside a designed vertical canvas or reshoot. A crop can remove the subject; a background layout can preserve the full frame but makes the important picture smaller. Choose based on what the viewer must see rather than treating fill as the only goal.

Square and landscape can be intentional for film excerpts, screen recordings or side-by-side explanations. Make the unused vertical space useful with context, captions or a second visual. Preview the result at phone size, because a technically legible desktop layout can become tiny in the feed.

A 1080 × 1920 export is a sensible target for most organic posts. TikTok's business guidance recommends at least HD-quality vertical creative, but uploading more pixels does not guarantee that viewers receive a higher-resolution stream. TikTok processes and serves versions suited to devices and connections.

Keep the frame rate consistent with the source unless you have a production reason to change it. Converting 30 frames per second footage to 60 does not create real motion detail, while converting mixed or variable-frame-rate footage can cause audio drift or uneven motion. For troublesome phone captures and screen recordings, render a constant-frame-rate master before upload.

Bitrate controls how much information is available to the encoder. An extremely low bitrate creates blockiness before TikTok even processes the file; an unnecessarily huge bitrate creates a large upload without promising better delivery. Use a high-quality preset in a reputable editor, review areas with motion, gradients and small text, and raise bitrate only when the master visibly needs it.

Clean capture matters more than chasing a headline resolution. Good light, controlled noise, stable focus and readable contrast survive compression better than a dark, noisy file labeled 4K. Keep an untouched high-quality master so you can make a new export if platform processing changes.

The app overlays navigation, creator information, captions and interaction controls on the video. The right side commonly holds profile, like, comment and share controls; the lower area can contain the username, caption, sound and navigation. Buttons can move, captions can expand and phone cutouts or system bars can change the visible area.

Keep essential faces, product details and text away from the extreme edges, especially the right and bottom. But do not rely on a single percentage copied from a template as universally safe. Preview inside TikTok on representative phones, expand the caption, and inspect any call-to-action or accessibility controls that your audience may see.

Build reusable guides in your editor as non-exporting overlays. Label them with the date and target placement, because an organic post, a Spark Ad and another advertising format may have different interface layers. Place secondary decoration near the edges and keep the message in a conservative central area.

The honest answer is the maximum shown by your current creation flow. TikTok has expanded and tested video lengths over time, and recording inside the app can offer different options from uploading an existing file. Availability may differ between accounts and regions. Open Add post, inspect the recording choices and attempt the intended upload before committing a production to a remembered limit.

Do not confuse an advertising placement's duration rule with the organic app's maximum. An ad format can impose a narrower range, and a campaign objective or placement can have its own specifications. Likewise, a feature announcement does not prove that every account received it.

If a long upload is rejected, divide the idea into coherent parts only when each part gives the viewer something complete. Otherwise make a shorter edit and link the extended version through an appropriate channel. Do not use a third-party uploader that requests account credentials to bypass a limit.

There is no universal duration that TikTok rewards. The useful length is the time required to deliver the promised idea clearly, without padding and without cutting away information the viewer needs. A concise demonstration may take twelve seconds; a careful explanation may need several minutes.

Use analytics as evidence about your own audience, not as a mandate to hit a viral ratio. Compare videos with similar topics and purposes. Look at where viewers leave, whether they reach the promised result, and whether the opening accurately prepares them for the rest. A low average on a long tutorial can still accompany valuable outcomes, while a looped short clip can show repeat playback without building trust.

Edit in passes. First remove setup the viewer does not need. Then tighten repeated sentences and pauses. Finally check whether the pace still allows captions to be read and instructions to be followed. Faster is not always clearer, and a completion percentage by itself does not explain satisfaction or intent.

Do not rely on the old claim that TikTok has one permanent file-size ceiling for iOS and another for Android. Limits can vary by upload route and platform release, and TikTok may change them. The current app's validation message is the relevant limit for an organic file; TikTok Ads Manager publishes separate specifications for ad assets.

MP4 and MOV are useful container choices, but a filename extension does not reveal everything inside. A MOV can contain a codec that a device or upload flow handles poorly. When compatibility matters, H.264 video with AAC audio in an MP4 is a conservative starting point. If it fails, export a fresh file rather than merely renaming the extension.

Reduce an oversized file by trimming unused material, using a reasonable bitrate and removing unnecessary audio channels before lowering resolution. Preserve the master. Compressing the only copy repeatedly causes cumulative damage and makes future exports worse.

Use simple filenames without unusual control characters and keep enough free device storage for TikTok to process the upload. Transfer the file in a way that does not silently compress it; some messaging apps create a smaller copy before it reaches the publishing phone.

A cover helps a profile visitor understand the grid, but its crop can differ from the full video. Choose it after checking the profile preview, keep the subject central and use few enough words to read at thumbnail size. Do not assume a precise crop remains permanent across every profile layout.

Burned-in text should remain inside the safe area and have enough contrast against every underlying frame. Platform captions can improve accessibility and allow edits within the features TikTok provides, while carefully authored on-screen text can be part of the visual design. When possible, review automatic transcription and correct names, numbers and specialist terms.

Do not place essential information only in audio or tiny graphics. Include captions for speech, write link or disclosure information clearly, and allow enough time to read a text card. Accessibility improvements also make a video more usable in noisy or sound-off settings, without promising any distribution benefit.

Inspect the exported master before blaming the platform. If it is already soft, blocky or noisy, re-export from the original timeline. Check that the editor did not use a low-quality social preset, crop a small source far beyond its resolution or render text before scaling the composition.

Next, upload over a stable connection and wait for processing. The first playback immediately after publishing may not represent every version TikTok will serve. Compare on Wi-Fi and mobile data, confirm that a data-saving setting is not affecting playback, and ask a second device to view the published post.

Fine texture, confetti, smoke, fast camera movement and dark noise are difficult to compress. Improve light, simplify backgrounds, avoid excessive sharpening and use controlled motion where the idea allows. Exporting at an enormous resolution cannot restore detail that the source never captured.

Watch the complete export once with sound and once muted. Check the opening frame, spelling, audio synchronization, music rights, caption accuracy, safe zones and final frame. Scrub through cuts for single-frame flashes or black gaps. Confirm that any claim, price or date is current at publication.

Upload privately or as a draft when the account's current controls allow an appropriate preview, but remember that local drafts can be device-bound. Test the actual post layout without risking your only master. For a commercial campaign, use the preview and technical specification supplied by the exact Ads Manager placement.

Archive the source project, clean master, final upload file, cover, caption and rights information together. A disciplined archive makes revisions straightforward when TikTok changes a limit or when you need a differently framed version for another platform.
