Social Media Video Aspect Ratios and Sizes (2026 Chart)
Short answer: use 9:16 at 1080×1920 for TikTok, Instagram Reels, YouTube Shorts, Snapchat and Pinterest Idea ads. Use 4:5 for Facebook feed video (Meta recommends 1440×1800) and vertical LinkedIn feed video, 1:1 where a square placement is all you have, 16:9 at 1920×1080 for YouTube and every horizontal placement, and 2:3 at 1000×1500 for standard Pinterest pins. Every value below links to the platform's own spec page, checked in September 2026.
Calculate sizes, then check the safe zone
The Aspect Ratio Calculator turns any ratio into exact pixel sizes and scale factors. The Safe Zone Checker then draws each platform's interface over your frame. Both run in your browser with nothing uploaded.
Aspect ratio versus resolution
The aspect ratio is the shape of the frame, width to height. The resolution is how many pixels fill that shape. 1080×1920 and 2160×3840 are both 9:16, and 1080×1350 and 1440×1800 are both 4:5. Platforms usually state a ratio plus a minimum or recommended resolution, so the two numbers answer different questions: will the video fill the placement, and will it look sharp once the platform compresses it.

| LinkedIn single image ads | 1.91:1, 1:1, 4:5 | 1200×628, 1200×1200, 720×900 px |
Meta's own guides now list 9:16 for Instagram feed video and 4:5 for Facebook feed video. If you can only afford two cuts for Meta, a 9:16 version for Reels, Stories and the Instagram feed plus a 4:5 version for the Facebook feed follows both recommendations. The full breakdown lives in our Meta ad specs guide.
How much of a phone screen each ratio fills
On a 9:16 phone screen, a video that fills the width covers this share of the frame. This is plain geometry, before any platform interface is drawn on top:
| Ratio | Height at 1080 px wide | Share of a 1080×1920 screen |
|---|---|---|
| 9:16 | 1920 px | 100% |
| 2:3 | 1620 px | 84.4% |
| 4:5 | 1350 px | 70.3% |
| 1:1 | 1080 px | 56.3% |
| 16:9 | 607.5 px | 31.6% |
That is why vertical formats dominate mobile placements. A landscape video on TikTok or Reels uses less than a third of the screen it is shown on.
Safe zones by ratio
The ratio decides the frame. The safe zone decides what survives the interface. These are the official vertical ad templates on 1080×1920:
- TikTok In-Feed Ads: 240 px top, 660 px bottom, 120 px sides, plus an action column at x 780 to 960 from y 840 down. See the TikTok safe zone guide.
- Instagram Reels and Stories ads: 14% top, 35% bottom and 6% on each side, which is 269 / 672 / 65 px. See the Reels template.
- YouTube vertical video ads: 288 px top, 672 px bottom, 48 px left, 192 px right. See the Shorts safe zone guide.
- Snapchat ads: 192 px top, 672 px bottom and 65 px sides, plus a block on the lower right at x 918 to 1015 from y 1056 to 1248 that keeps the profile and call to action icons clear, from Snap's single safe zone spec. See the Snapchat guide.
- Pinterest Idea ads: 270 px top, 440 px bottom, 65 px left, 195 px right. See the Pinterest guide.
One box that clears all five: x 120 to 885 and y 288 to 1248, which is 765 × 960 px. Below y 840, stay left of x 780 as well, because of TikTok's action column. A title, subtitle or offer inside that box is safe on every official vertical ad template at once.
For 16:9, Google's horizontal YouTube ads template keeps 38 px at the top and left, 387 px at the bottom and 162 px on the right, with deeper blocks at the top corners; TV uses 3.5% action safe and 5% title safe per edge (EBU R95). For 1:1 and 4:5 feed video, Meta publishes no pixel margins, so the checker applies a 5% margin as a convention.
Reframing 16:9 footage for 9:16
A 9:16 window cut from a 16:9 frame is 31.6% of its width. From a 3840×2160 master that window is 1215×2160 px, which scales down to 1080×1920 with no loss. From a 1920×1080 master the window is only 607.5×1080 px and has to be scaled up by 1.78, which is visibly soft. If a shoot needs both a YouTube cut and vertical cuts, record 4K and keep the subject and all action inside the central third of the frame.
The Aspect Ratio Calculator does this arithmetic for any source size, and the Safe Zone Checker shows whether the reframed crop still clears each platform's interface.
Export settings that platforms publish
Only some platforms publish encoding recommendations. YouTube's are the most complete, and they work as a safe baseline elsewhere:
| Setting | What the platform says |
|---|---|
| Container and codec | YouTube: MP4, H.264 High Profile, progressive scan. Snapchat: .mp4 or .mov, H.264. Meta Reels: H.264, square pixels, fixed frame rate, progressive scan. |
| Video bitrate | YouTube SDR: 8 Mbps at 1080p and 24 to 30 fps, 12 Mbps at 48 to 60 fps; 35 to 45 Mbps at 4K and 24 to 30 fps, 53 to 68 Mbps at 48 to 60 fps. TikTok auction In-Feed Ads: at least 516 kbps. |
| Frame rate | YouTube: export at the frame rate you recorded. LinkedIn: less than 30 fps. |
| Audio | YouTube: AAC-LC or Opus, 48 kHz, 384 kbps for stereo. Meta Reels: stereo AAC at 128 kbps or more. Snapchat: two balanced channels, AAC or PCM, at least 192 kbps, 48 kHz, target loudness of -16 LUFS. |
Aspect ratio FAQ
What is the best aspect ratio for social media video in 2026?
9:16 at 1080×1920 for every short form vertical placement. Add a 4:5 cut for feeds and a 16:9 cut for YouTube and horizontal placements if the budget allows three versions.
Is 1080×1350 the same as 4:5?
Yes. 1080 divided by 1350 is 0.8, which is 4:5. Meta's recommended 1440×1800 for Facebook feed video is the same ratio at a higher resolution.
What happens if I upload a 16:9 video to TikTok or Reels?
TikTok accepts 16:9 ads at 960×540 or more, but on a vertical phone screen the video covers about 31.6% of the frame. Vertical is TikTok's recommended format for a reason.
What size is a 4K vertical video?
2160×3840. Every safe zone value scales by exactly 2 from 1080×1920.
Which ratio should I use for Pinterest?
2:3 at 1000×1500 for standard pins. Video can use any ratio from 1:2 to 1.91:1, and Pinterest recommends 1:1, 2:3, 4:5 or 9:16. Idea ads use 9:16 with their own safe zone.
How do I check if text fits inside the safe zone?
Drop the file into the Safe Zone Checker. It detects the ratio and offers every platform that uses it, with the official template where one exists.
