Write for a text-heavy feed
X's timeline is mostly text — an image ad needs to read clearly at a glance rather than compete on visual density, since it's sitting between dozens of plain-text posts rather than other polished creative.
X's timeline moves faster than almost any other feed, and ad creative has to compete with real-time conversation, not just other ads. Describe the product, and generate a timeline-ready image without a design tool.
Specs
X doesn't publish a placement library the way Meta or LinkedIn does, but these four sizes cover the ad manager's core image and video specs.
| Placement | Aspect ratio | Recommended size | Notes |
|---|---|---|---|
| Timeline image (landscape) | 16:9 | 1200×675 | The most common crop; X trims aggressively so keep the subject centered. |
| Timeline image (square) | 1:1 | 1200×1200 | A safer bet in a mixed feed of text and image posts — less likely to get cropped unpredictably. |
| Video ad thumbnail | 16:9 | 1280×720 | Autoplay is muted by default, so the first frame has to carry the message alone. |
| Website card | 1.91:1 | 800×418 | A small thumbnail next to the headline text — detail gets lost below this size. |
Research
X's transparency center is narrower than most — it covers political and issue-based advertising disclosure specifically, not a general archive of commercial creative. There's no equivalent to what the ad creative glossary entry describes as a standard, searchable ad archive.
Day-to-day product ads — the kind most DTC and B2B advertisers actually run on X — simply aren't searchable through any official tool. There's nothing to look up, competitor or otherwise, so any research has to happen by scrolling the timeline itself and hoping a relevant ad shows up.
Limits
Any visibility at all into everyday commercial ads on the platform. Without a research tool to lean on, building from scratch — or from a generator — is close to the only option, and waiting for a competitor's ad to happen to appear in your own feed isn't a strategy.
With no ad archive to research, start from the brief instead. Describe the product and generate a timeline-ready ad directly.
Try It FreeFaster Path
X ads compete with real-time conversation, not a curated feed — the strongest ones read like they belong in the timeline, not like an interruption to it. Describe the product and offer, and the generator produces a landscape or square creative sized for X's timeline, with copy built to hold up next to short-form text posts rather than reading like a banner dropped into a conversation.
Because there's no dedicated X placement in most ad tooling, this generator reuses the same landscape feed sizing Meta uses for its own feed placements — the closest match to how X actually crops and displays image ads, and a size the platform's ad manager already accepts without complaint.
Creative Tips
X's timeline is mostly text — an image ad needs to read clearly at a glance rather than compete on visual density, since it's sitting between dozens of plain-text posts rather than other polished creative.
16:9 matches how X most commonly renders image ads inline; square assets sometimes get cropped unpredictably depending on surrounding post density and device.
X's audience scrolls fast between short posts — put the specific offer in the first few words rather than building up to it, since most viewers won't linger long enough to reach a slow reveal.
Since autoplay is muted, the first frame of any video ad needs to work as a standalone static image — assume most viewers will judge it before ever tapping to unmute.
X FAQ
Not for commercial ads. X's transparency center covers political and issue-based advertising specifically — everyday product ads aren't searchable through any official tool, no matter how large the advertiser.
1200×675 (16:9 landscape) is the most common crop for timeline image ads. 1200×1200 square is a safer alternative in a feed with mixed post densities and unpredictable cropping.
X doesn't publish a dedicated placement spec the way Meta or LinkedIn do. The landscape feed sizing Meta uses for its own feed is the closest practical match to how X displays image ads inline, so it's the safer default until X publishes its own guidance.
Not through an official X tool for standard commercial ads — that research option simply doesn't exist on this platform the way it does on Meta or TikTok. Generating directly from a brief is closer to the only workable path, rather than waiting to spot a competitor's creative by chance.
Yes. Selecting X shifts the copy toward the punchier, front-loaded style that holds up next to short-form text posts, rather than the longer captions that work on Meta or LinkedIn, where readers expect more context up front.
