TikTok / TikTok Shop video specs
Updated 2026-08-15 · Risk-term list version 2026-08-15c
TikTok / TikTok Shop: 9:16, up to 60 seconds, safe area 顶部 130px、底部 480px 留白（右侧交互栏 140px）.
7 of the 8 fields below come from the official page (opened and linked on 2026-08-15); the rest are marked 🟡 experience-based. We do not invent citations.
Specs are only the entry ticket. What gets an asset rejected is the claims, and each platform words those rules differently — the last section covers this one.
Read this first: markets where the category cannot run
Underwear and shapewear, including bras, thongs, microthongs, underwear, and any kind of shapewear — the policy says "shown on or off a model", so a flat-lay product shot is covered too.
The policy page lists 16 markets by name:
- Albania
- Brunei
- El Salvador
- Ethiopia
- Honduras
- Kyrgyzstan
- Laos
- Libya
- Mali
- Mauritius
- Monaco
- Myanmar
- Nicaragua
- Senegal
- Tanzania
- Uganda
This is a different axis from the risk-term list: the term list governs what you may say, this governs where you may run it at all. Cleaning up the copy does not help — and because it does not surface as a creative rejection, it is easy to misread as "the video is weak" and keep re-cutting. Check the targeting for these 16 markets before you launch. The US, the main market here, is not on the list, but multi-market rollouts hit it.

The specs, item by item
The third column is the provenance of that row. “From official page” means the number is copied from one of the pages under Sources; “🟡 experience-based” means the official page does not state it and this comes from campaign experience — do not cite it as platform policy. Checked 2026-08-15.

How this platform reads claims
The line that matters most for shapewear: TikTok's misleading-content policy names before-and-after comparisons that give a distorted impression of results, and uses an instant weight-loss promise as its example. Meta words this differently — do not merge the two into one rule.

One shoot, two aspect ratios
Cross-platform is the structural difference from the platforms’ own tools: TikTok’s does not leave TikTok, Meta’s does not leave Meta. But the same SKU goes to TikTok Shop, Meta, Shorts, Temu and Amazon. Four of those take 9:16; Amazon Sponsored Brands video is documented as "16:9 only" with no vertical option — so it is one shoot and two aspect ratios, not one cut everywhere.
| Platform | Aspect | Max length | Safe area | Notes |
|---|---|---|---|---|
| TikTok / TikTok Shop | 9:16 | 60s | 顶部 130px、底部 480px 留白（右侧交互栏 140px） | 前 3 秒必须出核心信息；字幕默认开；AI 生成内容需自觉标注，平台亦会自动打标 |
| Meta（Reels / Feed） | 9:16 主投，另交付 1:1 备用 | 30s | 上下各留 14% 给 UI | Advantage+ 会自动裁切，关键信息务必居中；同素材建议提供静音可懂版本 |
| Temu 站内 | 1:1 与 3:4 | 30s | 四周 8% 安全边 | 商品主体必须在前 2 秒出现且占画面 40% 以上；价格标签避免直接烧录，便于改价复用 |
| Amazon（Sponsored Brands 视频） | 16:9（官方页写的是 only，没有竖版选项） | 45s | 避开右下角放文字与关键信息；不要带黑边 / 色边 / 模糊边 | 6–45 秒，官方强烈建议 ≤20 秒；视频与投放市场的语言要一致（英文市场需英文字幕或英文口播） |
| YouTube Shorts | 9:16 | 60s | 底部 15% 避开标题条 | 完播权重高，结尾留 1 秒静帧做循环感 |
The practical version: frame with horizontal headroom, then export two — a 9:16 master (key elements inside the middle 50% of the height, plus a 1:1) and a 16:9 for Amazon. Do not fake the 16:9 with bars: Amazon’s spec page explicitly says to avoid black, colour or blurred bars.

FAQ
When do these numbers go stale?
The platforms’ own pages change. We stamp the date we checked (2026-08-15) and the “last updated” the page states, so you can judge when to re-verify. Go by the platform’s current rules before you spend, especially for safe areas, which move with UI redesigns.
Why are some fields marked experience-based?
Because the official page genuinely does not state them. Composition safe areas are the usual case: most platforms publish technical parameters and no framing guidance. Rather than invent a source, we mark the row so you know it carries less weight.
Does composing to the tightest safe area waste frame?
It costs you some edge, and it buys you one cut that runs everywhere. For a seller with many SKUs and weekly creative refresh, reshooting costs far more than the edge.
Do AI-generated assets need a label?
On TikTok, yes — tick the disclosure in Ads Manager or add a clear disclaimer, caption or watermark yourself; undisclosed AI content that is detected gets rejected or restricted. Other platforms: go by their current rules. Worth saying: we do not make videos. This note is for when you use someone else’s generator.
