Paid Social Size Guide 2026: Every Platform, Every Format
Complete 2026 ad size specs for Meta, TikTok, YouTube, LinkedIn, Pinterest, X, and Snapchat — dimensions, ratios, safe zones, and file limits in one reference.
Your designer just exported 12 ad assets. Three are the wrong dimensions. Two have text cropped by platform UI. One is 5 MB over the file limit. This happens on 40% of campaign launches according to a 2025 Celtra production audit — and every rejected or cropped asset delays your go-live by hours.
This is the size guide you bookmark once and reference every time you brief creative. It covers every major paid social platform and every ad format updated for 2026, including the specs that changed in Q1. No guessing, no Googling, no "I think it's 1080 by something."
Stop resizing ads by hand. Use AdConvert's ad resizer to auto-generate every format from a single master asset in seconds.
How to Use This Guide
Each platform section includes a complete specification table covering dimensions, aspect ratios, safe zones, file size limits, and format-specific notes. The tables are organized by placement type (Feed, Stories, Reels, etc.) so you can quickly find exactly what you need.
Three rules for using this guide effectively:
- Start with your budget allocation — produce sizes for the platforms where you spend the most first
- Design to the safe zone, not the full canvas — platform UI elements (profile names, CTA buttons, captions) overlay the edges
- Export master files at the largest dimension — downscaling is lossless, upscaling is not

TikTok
TikTok is a vertical-first platform. All ad formats are designed for full-screen 9:16 consumption.
Video Ad Specs
| Placement | Dimensions (px) | Aspect Ratio | Max Length | Max File Size | Min Resolution |

TikTok's content area is smaller than you think. After accounting for UI overlays on all four edges, your actual visible content area is roughly 750 x 1300px within a 1080 x 1920 canvas. Place all critical text and product shots within this zone.

Universal Best Practices
No matter which platform you are producing for, these rules apply to every ad asset:
| Rule | Why It Matters |
|---|---|
| Export at 2x resolution when possible | Retina displays render at higher density |
| Use H.264 codec for all video | Universal platform compatibility |
| Keep video under 30 seconds | Completion rates drop sharply after 30s |
| Add captions/text overlays | 85% of social video is watched on mute |
| Test 9:16 first, then 1:1 | Vertical takes priority on mobile-first platforms |
| Compress images to under 500 KB when possible | Faster ad load = better delivery |
| Use PNG for graphics, JPEG for photos | Match format to content type for quality vs. size |
Tip
Produce once, resize automatically. Instead of manually creating assets for every platform and placement, use AdConvert's ad resizer to generate all required formats from a single master creative. This eliminates sizing errors and cuts production time by 80%.
