Twitter Image Ads: Specs for App Buttons, Polls, Website Cards, and More

X/Twitter Image Ad Specs

X image ads use the same core visual rules across several CTA formats, but each format adds its own limits for copy, app metadata, poll options, conversation flows, or website card fields. Use the checklist below when preparing static image creatives for X Ads.

Media headline length: max 70 characters.
Truncation guidance: up to two lines may render on the card title; limiting the headline to 50 characters is safer across most devices.

Standalone Image Ads

Image size: 1200 × 1200 px recommended for 1:1; 1200 × 628 px recommended for 1.91:1.
Expanded image view: larger images are better optimized when users click to expand.
Best use: simple image-led promotion without app, website card, poll, or conversation mechanics.

Keep image headlines and CTA text shorter than the maximum whenever possible. Device size, app settings, and card rendering can affect how much copy is actually visible.
