TikTok is the fastest-growing ad platform — and the most unforgiving about specs. Get the dimensions wrong and your ad gets cropped. Use the wrong file format and it doesn't run at all.

This guide covers every TikTok ad format with exact specs, file requirements, and character limits for 2026.

Why TikTok Ad Specs Are Different

TikTok is built for vertical mobile video. Unlike Meta or Google — where you might get away with a landscape creative — TikTok's placements are almost entirely 9:16. Static image ads are rare; video is the default expectation.

The platform also has stricter safe zone requirements than most. UI elements (like/comment buttons, captions, profile info) overlay a significant portion of your creative. Place your key message in the wrong zone and it gets covered.

Know your safe zones. Plan for them.

In-Feed Ads

The most common TikTok ad format. Appears in the For You Page between organic videos, looks and feels like native content.

Video specs:

Aspect ratio: 9:16 (vertical) — required. 1:1 and 16:9 also accepted but underperform.
Recommended resolution: 1080 x 1920px
Minimum resolution: 540 x 960px
File types: MP4, MOV, AVI, GIF
Max file size: 500MB
Duration: 5–60 seconds (9–15 seconds recommended for performance)
Frame rate: 23–60 fps

Safe zones:

Bottom: 130px — reserved for profile info, caption, and music ticker
Right: 86px — reserved for like/comment/share buttons
Keep all key visuals and text within the center safe area

Character limits:

Ad name: Up to 512 characters (internal label)
Display name: Up to 20 characters (shown on ad)
Video caption: Up to 100 characters (shown below ad)
CTA button: Predefined options (Shop Now, Learn More, Download, Sign Up, etc.)

Best practice: The first 1–2 seconds make or break your ad. TikTok users swipe instantly. Open with movement, bold text on screen, or a surprising visual — never a logo or title card. Sound on by default, but design so it works with captions too.

TopView Ads

Full-screen takeover that appears as the very first thing users see when they open TikTok. Highest visibility placement on the platform.

Specs:

Aspect ratio: 9:16 vertical only
Resolution: 1080 x 1920px
File types: MP4, MOV
Max file size: 500MB
Duration: 5–60 seconds (first 3 seconds are autoplay without sound)
Frame rate: 23–60 fps

Character limits:

Display name: Up to 20 characters
Ad description: Up to 80 characters (visible in full-screen view)
CTA: Up to 16 characters

Best practice: TopView starts with 3 seconds of silent autoplay. Make those first 3 seconds visually compelling without relying on audio. Use large on-screen text or dramatic visuals that stop the thumb immediately.

Brand Takeover

A 3–5 second full-screen ad (image or short video) that appears before the user's For You feed loads. No competing content around it — 100% share of screen.

Image specs:

Size: 1080 x 1920px
File types: JPG, PNG
Max file size: 50MB
Duration: 3 seconds (static display)

Video specs:

Aspect ratio: 9:16
Resolution: 1080 x 1920px
File types: MP4, MOV
Max file size: 500MB
Duration: 3–5 seconds

Character limits:

Display name: Up to 20 characters
Ad description: Up to 80 characters

Best practice: You have 3–5 seconds and zero competing context. One message only. Don't try to tell a story — make an impression. Brand Takeover is for brand awareness and product launches, not complex feature explanations.

Branded Hashtag Challenge

Promoted hashtag + dedicated challenge page. Users are invited to create content using the hashtag.

Banner creative specs:

Size: 1080 x 720px (challenge banner)
File type: JPG, PNG
Max file size: 10MB

Branded effects (optional):

Sticker size: 128 x 128px minimum

Character limits:

Hashtag name: Up to 30 characters
Challenge description: Up to 150 characters

Best practice: The best hashtag challenges give users a clear, simple, and repeatable creative prompt. Make it easy to participate and fun to watch. The challenge itself drives organic reach — your paid media just seeds the spark.

Spark Ads (Boosted Organic Posts)

Boost existing organic TikTok posts (your own or creator content with permission) as ads. Same specs as the original post, but with ad targeting and CTA overlay.

No separate creative specs — the organic post specs apply
Requires authorization from the account owner (for creator posts)
CTA button: Add any standard TikTok CTA to the original post
Minimum video duration: 3 seconds

Best practice: Spark Ads convert better than standard In-Feed Ads in most categories. Find your best-performing organic posts and boost them. Creator-authorized Spark Ads (with authentic voice) often outperform polished brand creative.

Search Ads

Text-based ads that appear in TikTok search results. Relatively new format, growing fast.

Specs:

Ad format: Pulls from existing In-Feed Ad creative (same 9:16 video or image)
Targeting: Keyword-based

Character limits:

Headline: Up to 30 characters
Description: Up to 100 characters

Best practice: Search intent on TikTok is different from Google. Users are searching for entertainment, tutorials, and products they've already heard about. Creative should feel native to TikTok, not like a Google Search ad.

TikTok Safe Zone Reference

This is the most commonly ignored spec — and the most costly mistake.

┌─────────────────────────┐ ← Top of screen
│                         │
│   SAFE CONTENT ZONE     │
│   (center 80% of       │
│    the screen)          │
│                         │
│                    [♥]  │ ← Like button (right 86px)
│                    [💬] │ ← Comment
│                    [↗]  │ ← Share
├─────────────────────────┤
│ @username  Caption text │ ← Bottom 130px — do not place
│ ♫ Song name             │    key content here
└─────────────────────────┘

Keep your logo, key message, and CTA text in the center safe zone — at least 130px from the bottom and 86px from the right edge.

The TikTok-First Creative Principle

TikTok's algorithm punishes creative that looks like an ad. The best-performing TikTok ads:

Open with movement or a hook — first 1–2 seconds determine if users swipe
Use native TikTok text overlays — on-screen text captions outperform polished graphics
Sound matters — trending audio or clear voice-over dramatically increases watch time
Show a real outcome in the first 3 seconds — don't build to a reveal, open with it
Keep it under 15 seconds — shorter is almost always better for performance campaigns

Key Takeaways

9:16 is non-negotiable — TikTok is a vertical platform. 1:1 and 16:9 technically work but underperform significantly.
Respect the safe zones — bottom 130px and right 86px are covered by UI. Plan around them.
First 2 seconds decide everything — open with your hook, not your brand.
Keep captions short — 100 characters maximum, and lead with the value in the first 50.
Spark Ads > standard In-Feed — boosting organic content usually beats polished brand creative.
