TikTok Ads Specs and Benchmarks for 2026
A spec sheet for every TikTok ad format plus benchmark tables for CTR, CPM, and CVR by vertical, and three ad-format examples that show what's working in 2026.
A reference page, not a hot take. The TikTok ad specs change often enough that the answer to “what aspect ratio do I use” deserves a current source. The benchmarks change with the platform’s algorithm shifts. This is the 2026 version of both, plus the format examples we’d point to when asked what’s actually working on TikTok this quarter.
TL;DR
- Default specs: 9:16 vertical, 1080×1920 pixels, MP4 or MOV, H.264 codec, under 500MB, 9 seconds to 60 seconds for In-Feed Ads.
- The sweet spot for length in 2026 is 15-30 seconds. Shorter than 9 seconds and TikTok caps your reach. Longer than 30 seconds and watch-through drops sharply.
- Good TikTok CTR in 2026 sits around 1.0-1.5% for DTC, lower for mobile apps (0.8-1.2%), higher for low-consideration ecom (1.5-2.5%).
- CPMs vary 5x by vertical. Finance and B2B hit $20+ CPMs. Beauty and DTC consumables sit at $5-12 CPMs.
- The three formats actually scaling in 2026: In-Feed talking-head with hard hook, Spark Ads boosted from organic, multi-scene UGC-style demos.
TikTok ad specs by format
The full spec table, current as of mid-2026. Sources: TikTok Business Center, TikTok Ads Manager, and the TikTok Creative Center documentation.
In-Feed Ads (the default format)
| Spec | Value |
|---|---|
| Aspect ratio | 9:16 (vertical) — also accepts 1:1 and 16:9 but degraded reach |
| Resolution | 1080×1920 minimum |
| File format | MP4, MOV, MPEG, AVI, GIF |
| Codec | H.264 (recommended) or H.265 |
| File size | Up to 500MB |
| Video length | 5-60 seconds (sweet spot 9-30s) |
| Bitrate | 516+ kbps |
| Frame rate | 23-60 fps (30 fps recommended) |
| Audio | AAC or MP3, 44.1kHz |
| Brand name | 2-20 English characters |
| Ad description | 1-100 English characters (1-50 Asian) |
| Landing page URL | Required, must be HTTPS |
In-Feed Ads appear in the native For You feed between organic content. They support full CTA buttons (Shop Now, Download, Sign Up, Learn More) and click through to your landing page or app store.
Spark Ads (boosted organic)
| Spec | Value |
|---|---|
| Aspect ratio | Inherits from original organic post (9:16 strongly preferred) |
| Resolution | Inherits from original |
| Video length | Up to 60 seconds for paid distribution |
| Source | An existing organic TikTok post (yours or a creator’s, with permission) |
Spark Ads boost an existing organic post. They retain the original handle, comments, likes, and shares — which is the entire reason they outperform regular In-Feed ads. The native feel is the format. Most operators we know run 50-70% of paid TikTok spend through Spark Ads in 2026.
TopView (premium reach)
| Spec | Value |
|---|---|
| Aspect ratio | 9:16 |
| Resolution | 1080×1920 minimum |
| Video length | 5-60 seconds (15s recommended) |
| File size | Up to 500MB |
| Format | MP4, MOV |
| Placement | First in-feed impression after app open |
TopView is the format you see immediately after opening TikTok. Premium pricing (typically reserved-buy CPM model, $1K+ minimum spend). Best for brand launches and product reveals, not for performance budget allocation.
Top Feed (slightly lower-cost premium)
Sits in the top 3 positions of the For You feed. Same specs as In-Feed, premium placement, premium pricing.
Branded Hashtag Challenge
| Spec | Value |
|---|---|
| Aspect ratio | 9:16 |
| Video length | 9-60 seconds |
| Reserved spend | Typically $150K+ minimum |
| Duration | 6-day campaign window standard |
A campaign format that invites organic UGC participation. Performance budget rarely justifies it; brand-launch budget can.
Branded Effect
A custom AR effect (filter, sticker, lens) that users can apply to their own videos. Reserved-buy, $40K-$100K+ depending on complexity. Brand awareness play; rarely used in operator-led performance programs.
Carousel Ads (Image-Based)
| Spec | Value |
|---|---|
| Image format | JPG or PNG |
| Aspect ratio | 1:1 (square) |
| Resolution | 720×720 minimum, 1080×1080 recommended |
| Number of images | 2-35 per carousel |
| File size | Up to 1MB per image |
Image-only carousel that lives inside the In-Feed placement. Better fit for product catalogs than for storytelling. Less common than video formats in 2026 but useful for ecom catalog ads.
Lead Generation Ads
In-Feed format with a native lead form that opens in-app on tap. Same video specs as In-Feed Ads. Form fields configurable (email, phone, custom questions). Useful for lower-funnel B2B and service business lead capture.
Aspect ratio guidance
TikTok’s algorithm has a measurable preference for native vertical (9:16). Square (1:1) and landscape (16:9) ads will run, but expect:
- 9:16: full reach, full optimization, native feel.
- 1:1: roughly 60-80% of vertical reach in our experience, looks out of place.
- 16:9: reach degraded further, looks like a re-purposed YouTube or Meta asset.
If you’re repurposing creative across platforms, render the master in 9:16 and let TikTok’s own crop handle Meta and Google variants — not the other way around. Tools like Superscale, Creatify, and Arcads all output 9:16 by default and resize automatically; the broader field guide is our best AI ad creative tools of 2026.
How long should a TikTok ad be?
The honest answer in 2026: 15-30 seconds for most performance work.
The TikTok algorithm penalizes ads under 9 seconds in two ways: lower reach (the platform treats them as low-effort) and degraded post-click conversion (not enough time to make a real argument). The hard floor for In-Feed performance ads is 9 seconds.
The ceiling is around 60 seconds for In-Feed, longer for some campaigns, but watch-through drops sharply past 30 seconds. The pattern across operator data:
- 9-15 seconds: highest reach, best for hook + demo patterns, weakest for high-consideration products.
- 15-30 seconds: the operator sweet spot. Long enough to make an argument, short enough to retain.
- 30-60 seconds: works for high-consideration categories (SaaS, finance, high-AOV DTC) where the audience needs context.
- 60+ seconds: rarely competitive for paid performance. Reserve for YouTube-equivalent placements.
There’s also a hard floor at the format level: feed creative under 5 seconds is rejected outright by TikTok’s ad approval.
TikTok benchmarks for 2026
Numbers below are operator-collected medians across DTC, mobile apps, and B2B in 2025-2026. Treat them as starting reference. Your category mix, geo, and creative quality will move you 30-50% in either direction.
CTR (click-through rate)
| Vertical | Median CTR | Top quartile |
|---|---|---|
| DTC apparel | 1.2% | 2.1%+ |
| DTC beauty | 1.4% | 2.4%+ |
| DTC supplements | 1.1% | 1.9%+ |
| DTC food & beverage | 1.5% | 2.8%+ |
| Mobile apps (consumer) | 0.9% | 1.6%+ |
| Mobile games | 0.7% | 1.4%+ |
| B2B SaaS | 0.5% | 1.0%+ |
| Finance | 0.6% | 1.2%+ |
A “good” TikTok CTR for most DTC operators in 2026 is around 1.0-1.5%. Anything below 0.5% on a DTC product means the hook is failing in the first second.
CPM (cost per thousand impressions)
| Vertical | Median CPM (US) |
|---|---|
| DTC consumables | $6-10 |
| DTC fashion | $8-14 |
| DTC beauty | $10-16 |
| Mobile apps (consumer) | $7-12 |
| Mobile games | $4-8 |
| Finance | $18-28 |
| B2B SaaS | $15-25 |
US CPMs are typically 1.5-2x higher than the same vertical in UK, DE, or LATAM markets. Q4 (holiday) CPMs spike 30-50% above Q1 baselines.
CPC (cost per click)
CPC is the algebraic combination of CPM and CTR. For most DTC verticals in 2026, expect $0.50-$1.20 CPC on TikTok. Mobile gaming sits lower ($0.30-$0.70). Finance and B2B sit higher ($2.50-$6.00).
CVR (conversion rate, landing page → conversion)
CVR is a landing page property, not a TikTok property — but it’s the number that closes the ROAS equation.
| Vertical | TikTok-sourced landing page CVR |
|---|---|
| DTC ecom (median) | 1.5-3.0% |
| Mobile app install (App Store/Play conversion) | 25-40% (varies hugely by category) |
| Lead gen (native lead form) | 4-8% |
| Lead gen (off-platform landing page) | 1-3% |
TikTok-sourced landing page CVR is typically 30-50% lower than Meta-sourced — partly because the TikTok audience is more discovery-mode, partly because the click-through is lighter intent. Plan your ROAS math around that gap.
For the ROAS math itself, our ROAS playbook covers the full breakeven framework.
Three ad-format examples that work in 2026
Format examples drawn from operator-observed winners across DTC and mobile apps in the last two quarters.
Example 1: In-Feed talking-head with a hard hook
The default format and still the highest-performing for most categories. Structure:
- Second 1-2: a person on camera, looking straight into the lens, delivering a one-line hook. The hook is the entire ad’s reason for existing.
- Second 3-8: the body. Either a demo, a story, or a problem/solution beat.
- Second 9-15: the CTA. Soft on TikTok (“link in bio,” “check the website”) works better than hard CTA buttons for some audiences.
The hook patterns that scale this format are covered in our winning hook patterns of 2026 — street interview, “I tried this so you don’t have to,” third-person testimonial.
Example 2: Spark Ads boosted from organic UGC
A creator (or an AI-UGC character) posts a piece of native organic content. The brand boosts it via Spark Ads. The format retains the original handle, comments, likes, and shares.
Why it works: it doesn’t read as an ad. The TikTok algorithm rewards content that engages, and Spark Ads inherit the engagement signal of the original post.
The operator pattern: produce 10-20 organic posts per week (mix of in-house creators, paid UGC creators, and AI-UGC tools), promote the top 2-3 performers as Spark Ads. The TikTok Creative Center operator playbook covers the discovery-side workflow.
Example 3: Multi-scene UGC-style demo
A 15-30 second video with 3-5 hard cuts. Each cut is a different scene: hook, problem, product reveal, demo, CTA. The cuts create momentum and mirror the editing language of organic TikTok content.
Production reality in 2026: most multi-scene demos are produced inside an AI ad tool rather than shot with multiple takes. Tools like Superscale handle the multi-scene structure as a single workflow, including the character continuity and B-roll insertion that used to require a video editor. Creatify and Arcads sit in adjacent spaces with narrower feature sets.
What’s losing share on TikTok in 2026
A short list since this matters for what you stop making:
- Repurposed Meta Reels with brand color overlays. Reads as repurposed, performance suffers.
- 30-60 second cinematic without a hook in the first second. Beautiful, doesn’t convert.
- Heavy on-screen text in landscape format. TikTok is vertical-first. Heavy text in landscape reads as a YouTube re-cut.
- Static carousel ads as primary format. Useful for catalog SKUs; bad as the main creative driver.
Tools that generate to TikTok spec
If you’re producing TikTok ads at volume in 2026, the AI tool landscape has matured significantly. The shortlist that comes up most often in operator conversations:
- Superscale — AI ad agent that ships 9:16 by default, multi-scene, with native push-to-drafts on TikTok Ads Manager.
- Creatify — strong on UGC-style AI characters, easy to spin up native-feeling TikTok content at volume.
- Arcads — clip-generator focused on the actor/UGC layer.
- Foreplay — not a generator, but the swipe library every TikTok-running team uses for inspiration and competitor research.
For research and audience-side workflow, the TikTok Creative Center is the under-used native tool — top organic patterns, trending sounds, and category-level creative benchmarks all live there.
What we’d do
If you’re launching a new brand on TikTok in 2026:
- Default to 9:16, 15-30 seconds. Don’t try to be clever with format until you’ve shipped 30+ ads in the default.
- Run 50-70% of spend through Spark Ads. Organic-first creative outperforms paid-only creative on TikTok almost every time.
- Test 10-15 hooks per week. Hook is the single highest-leverage variable.
- Run two creative buckets in parallel. A “polished” bucket (designer or AI tool) and a “raw” bucket (UGC creators or AI-UGC tools producing native-feel content). Compare CTR and CVR weekly.
- Check the Creative Center weekly. The native research is the cheapest competitive intel TikTok ships.
The platform changes more often than Meta does. The specs in this post are current as of mid-2026; check ads.tiktok.com for the latest before a major launch.
FAQ
What is the best aspect ratio for TikTok ads?
9:16 vertical (1080×1920) is the only aspect ratio that gets full reach and native feel on TikTok. Square (1:1) and landscape (16:9) ads will run but reach is degraded and the ad reads as repurposed from another platform.
How long can a TikTok ad be?
In-Feed Ads run from 5 to 60 seconds. The performance sweet spot is 15-30 seconds. Under 9 seconds and the algorithm caps reach; over 30 seconds and watch-through drops sharply. TopView ads are also capped at 60 seconds.
What is a good CTR for TikTok ads?
For most DTC categories in 2026, a healthy CTR is 1.0-1.5%, with top-quartile performers above 2.0%. Mobile apps run lower (0.8-1.2%) and B2B and finance run lower still (0.5-0.7%). Anything below 0.5% on a DTC product usually means the hook is failing in the first second.
What file format does TikTok accept?
TikTok accepts MP4, MOV, MPEG, AVI, and GIF for video ads. MP4 with H.264 codec is the recommended combination. File size cap is 500MB. Bitrate should be 516 kbps or higher. Frame rate 23-60 fps, with 30 fps recommended.
Are Spark Ads better than In-Feed Ads?
For most operators in 2026, yes — Spark Ads typically outperform regular In-Feed Ads because they inherit the organic engagement signal and don’t read as branded content. The trade-off is you need the organic post first, either from your own account or licensed from a creator. Most TikTok-heavy brands now run 50-70% of paid spend through Spark Ads.

Letters from readers
-
Q·01 How is ad-stack funded?
We pay for every tool seat ourselves at the public plan tier, and the journal is reader-supported via the newsletter. No vendor pays for placement, and no review is sponsored.
-
Q·02 Why benchmark on the same brief instead of letting each tool play to its strengths?
Because the only fair variable in a head-to-head test is the tool. Letting each vendor pick their best demo brief is how the AI ad category got into its current marketing-led mess — every tool wins on its own showcase. Same brief means you can actually compare cost-to-published across the field.
-
Q·03 How often do you re-test tools that have shipped major updates?
Every quarter. Reviews carry a 'last tested' date in the byline. If a tool ships a meaningful capability change between quarterly cycles, we publish a field note rather than waiting — but the score on the main review only moves at the next full re-test.
-
Q·04 Can I send in a tool to be reviewed?
Yes — send a note via the contact link in the footer. We can't promise coverage of every submission, and being suggested has no bearing on the eventual verdict. Vendors who pay for seats themselves rather than offering us free credits are evaluated identically.
