Twitter ad formats & specs

Twitter Website Card

Image and Video Website Cards enable your brand to share image or video creative that seamlessly drives your audience to a landing page of your choice.

Video Website Card

Tweet copy

280 characters (Note: Each link used reduces character count by 23 characters, so for example, using one link would leave 257 characters for Tweet copy.)

Website title length

70 characters. Please note — depending on device and app settings this description may truncate. Although not guaranteed, limiting the description to 50 characters should ensure that truncation won’t occur across most devices.

File size

For optimal performance, keep files under 30MB. The max file size recommended is under 1GB.

Video length

Recommended: 15 seconds or less

Branding: Highly recommended throughout; if using a logo, it should be persistent in the upper left-hand corner.

Captions: Closed captioning or text overlays are mandatory.

File types

MP4 or MOV

Video bitrate recommendation

Recommended: 6,000k for 1080p, 5,000k for 720p

Max: 6,000k-10,000k for 1080p, 5,000k-8,000k for 720p

Frame rate recommendation

29.97fps or 30fps. Higher is acceptable. If the available video has a lower frame rate, don’t try to “upsample” it.

Audio codec recommendation

AAC LC (low complexity)

Video codec recommendation

H.264, baseline, main, or high profile with a 4:2:0 color space

Aspect ratio

1:1 is recommended as it will always render as square on desktop and mobile, timeline and profile. This and 9:16 (vertical) will take up the same amount of real estate — which is more than 16:9. Upon tap, full screen will open and fill with black bars.

Any aspect between 2:1 and 1:1 is acceptable, but after 1:1, platform will crop to 1:1 aspect ratio.

9:16 (vertical) will always render in a 1:1 space on desktop and mobile, timeline and profile. Desktop will have black bars on the sides once the video begins playing. Mobile will crop the top and bottom of the video, center, and autoplay without bars.

Recommended size

1200x1200 (minimum for 1:1 is 600x600)

  • Any height is acceptable, but if height exceeds the width, the video will be cropped to 1:1 in the feed.

  • If not a 1:1 aspect ratio: 640x360 minimum

Thumbnail

Supported files: PNG or JPEG

Aspect ratio: recommend matching sizing of the video

Max size: 5MB
