Platform Guidelines
Getting rejected for wrong specs wastes budget and delays campaigns. This guide covers the exact technical requirements for every major ad platform in 2026 — and explains how AIMS's platform presets keep you compliant automatically.

Mobile-first in 2026
Over 70% of Meta ad impressions are on mobile devices held vertically. Always design your primary creative in 9:16. If you only have bandwidth for one format, it should be vertical.
TikTok
| Spec | Requirement |
|---|---|
| Aspect ratio (recommended) | 9:16 vertical |
| Resolution | 1080×1920 (min 540×960) |
| Format | MP4, MOV, MPEG, AVI |
| Codec | H.264 preferred |
| Max file size | 500 MB |
| Optimal duration | 9–15 seconds |
| Maximum duration | 60 seconds (some accounts 10 min) |
| Safe zone — top | Keep content below top 150px |
| Safe zone — bottom | Keep content above bottom 175px (UI overlay) |
| Audio | Required and critical — 93% of TikTok users watch with sound on |
TikTok's safe zone matters more than people expect. The platform overlays its own UI elements — username, caption, like/share buttons — over the bottom 175px and top 150px of your video. Any text or key product detail in those zones will be obscured. AIMS's TikTok preset automatically positions your product and text within the safe zone.
Google (Display & YouTube)
| Format | Spec | Placement |
|---|---|---|
| Responsive Display Ad (image) | 1200×628, 1200×1200, 628×1200 | Google Display Network |
| YouTube In-Stream (skippable) | 1920×1080, MP4, 15–120 sec | Pre/mid/post-roll on YouTube |
| YouTube Shorts | 1080×1920, MP4, under 60 sec | YouTube Shorts feed |
| Discovery / Demand Gen | 1200×628 and 1200×1200, under 5 MB | Gmail, YouTube home, Discover |

How AIMS auto-resizes for each platform
When you click "Export by Platform" in the export panel, AIMS automatically generates your asset in every required size for each platform you select. Your product stays centred and well-composed in each format — AIMS reframes the shot rather than simply cropping, so the product doesn't get cut off when going from 1:1 to 9:16 or 1.91:1.
All platform presets are kept up to date as platforms change their requirements. If a platform updates its specs, the AIMS export preset is updated too.
