Ad specs / LinkedIn
LinkedIn video ad size
LinkedIn recommends 4:5 for video ads, at 720 × 900 pixels; it also takes 16:9 (1920 × 1080 or 1200 × 675 recommended), 9:16 at 720 × 1280 and square 1:1. A video runs 3 seconds to 30 minutes, as an MP4 between 75 KB and 500 MB, at under 30 frames per second.
| Format | Sponsored Content video in the LinkedIn feed |
|---|---|
| Vertical 4:5 | Recommended ratio; 720 × 900 pixels, minimum 360 × 450, maximum 1080 × 1350 |
| Horizontal 16:9 | 1920 × 1080 or 1200 × 675 pixels; minimum 640 × 360, maximum 1920 × 1080 |
| Vertical 9:16 | 720 × 1280 pixels; minimum 360 × 640, maximum 1080 × 1920 |
| Square 1:1 | No recommended size; minimum 360 × 360, maximum 1920 × 1920 |
| Widest ratio | 16:9. LinkedIn's example: a 1920 × 360 video is inside the width and height limits but too wide for an ad |
| Length | 3 seconds to 30 minutes; 15–30 seconds recommended, to qualify for every placement across the LinkedIn feed and Audience Network; in-stream video ads up to 90 seconds |
| File size | 75 KB to 500 MB |
| File type | MP4 |
| Codec | H.264 or VP8; Apple ProRes is not supported |
| Frame rate | Under 30 frames per second |
| Audio | AAC or MPEG4, under 64 kHz |
| Captions | An SRT file, text only; custom formatting such as font colors isn't supported |
| Thumbnail | Optional: JPG or PNG up to 2 MB, at the video's own aspect ratio and resolution |
| Introductory text | Up to 150 characters to avoid truncation, 3,000 at most, with up to 10 emojis; LinkedIn's page also says an ad might be rejected for non-standard text, which includes more than four emojis |
| Video headline | Up to 70 characters to avoid truncation on most devices, 200 at most |
| Playback | A video under 30 seconds loops until at least 30 seconds have played; a longer one plays once |
What the other guides get wrong
Guides cap LinkedIn video files at 200 MB, and one gives the frame rate as 30 fps. LinkedIn's page says between 75 KB and 500 MB, and less than 30 frames per second. Another recommends 1080 × 1920 for vertical video, which is LinkedIn's 9:16 maximum; LinkedIn recommends 720 × 1280.
