The recommended Twitter/X post image size for a single timeline graphic is 1600 × 900 px (16:9). That canvas works well for launch posts, blog promos, and other in-feed images where the graphic needs to stay readable after the timeline crops and compresses it.
This guide covers twitter image dimensions, layout tips, and common mistakes. Profile photos, headers, and ads use different rules. Here we focus on the single post image you attach to a timeline update.
Recommended size
| Dimension | 1600 × 900 px |
| Aspect ratio | 16:9 |
| Main use case | Single-image Twitter/X timeline posts |
| Use case | Recommended size | Aspect ratio | FeatureImg preset |
|---|---|---|---|
| Single timeline image (default) | 1600 × 900 px | 16:9 | X Post format |
| Wide announcement or launch graphic | 1600 × 900 px | 16:9 | Same canvas |
| Link-preview style asset (not a post image) | 1200 × 630 px | ~1.91:1 | Open Graph format |
For timeline graphics, design at 1600 × 900 px so twitter image dimensions stay consistent when you export. FeatureImg locks that canvas in the X Post editor.
Recommended Twitter and X post image size
The most practical twitter post size in pixels for feed graphics is 1600 × 900 (16:9). FeatureImg’s X Post format exports at that size so you design on the correct canvas and download without a separate resize step.
If your team already ships 1200 × 630 px Open Graph assets, those are closer to link-preview cards than in-feed post images. For timeline graphics, match 1600 × 900 px so exports align with the format page and editor.
Twitter and X image sizes by use case
Product launch or milestone. Use the full 1600 × 900 frame. One headline, optional subtitle, and a visual anchor (screenshot, product still, or simple background). The product update or creator bold templates on the templates page are a practical starting point.
Blog or newsletter promo. Same wide canvas. Keep the post title short on the image; put the URL and nuance in the post body. A quote or hero split layout can separate headline from visual proof.
Framework, checklist, or lesson. Prefer large type and generous spacing. Dense slide exports rarely survive mobile scrolling.
Data point or result. One number or one claim per frame. Pair with context in the post text.
Quote or hot take. Short lines read best. The quote card template supports author attribution when you want a tweet-style layout.
Link-only updates. If a link card already shows the right preview, you may not need a custom post image. When you want a stronger hook, design a timeline graphic instead of reusing OG art at the wrong ratio.
Why a wide image works in the feed
Timeline readers scroll fast. A wide image uses horizontal space well, keeps type large enough to scan, and gives you room for a headline plus a visual anchor.
Wide layouts also separate jobs cleanly: the image carries one visual promise, and the post text carries links, nuance, and thread context. That split works for launches, lessons, frameworks, and blog promos where the graphic should stop the scroll, not replace the full post.
Timeline readability tips
One message per image. Pick a single takeaway: the launch name, the metric, the lesson title. Do not paste the whole post into the graphic.
Use a readable headline. Aim for about five to eight words. Timeline thumbnails shrink quickly on mobile.
Keep contrast high. Light gray type on pale gradients fails on bright screens and in dark-mode timelines. Solid fields, simple gradients, or calm panels behind text usually hold up better.
Leave enough spacing. Clients can crop edges. Keep logos and words away from the outer border.
Use the post copy for details. URLs, bullets, and paragraphs belong in the post (or thread), not on the image.
Preview at small size. Zoom out in the editor or squint at the preview before export. If the headline disappears, simplify.
Twitter and X post image examples
These patterns map to layouts you can start from in FeatureImg:
| Example style | Best for | Template direction |
|---|---|---|
| Bold statement | Opinions, launches, short hooks | Creator bold |
| Product update | Features, changelog highlights | Product update |
| Data point | One metric or result | Data report |
| Framework / checklist | Lessons, threads promoted in one frame | Tutorial card or hero split |
| Quote with attribution | Insights, testimonials | Quote card |

Common mistakes
Wrong aspect ratio. Uploading square or tall art into a wide timeline slot leads to awkward crops or letterboxing.
Random stock photos. Generic imagery signals “placeholder update” instead of a specific story.
Too much text. Dense bullets and slide exports rarely survive mobile scrolling.
Low contrast. Pastel-on-pastel type disappears when the timeline is busy.
Unclear topic. If readers cannot tell what the post is about in one glance, the image did not earn its space.
Screenshots with unreadable UI. A full product capture without a cropped focus area often looks muddy at feed size.
Confusing OG art with post art. Twitter image specs for link previews differ from single-image post graphics. Use the right export for each job.

FAQ
What is the best Twitter post image size?
For single-image timeline posts, 1600 × 900 pixels (16:9) is the most practical twitter image size to design toward. FeatureImg exports at that size on the X Post preset.
What are the standard Twitter image dimensions for a post?
Twitter post dimensions for a wide timeline graphic are 1600 × 900 px. That is different from 1200 × 630 px Open Graph art used for link previews.
Is the X post image size the same as Twitter?
Yes for timeline graphics. Searchers use both x image size and twitter post image size for the same wide post attachment. Use 1600 × 900 px unless X documents a different requirement for a specific placement.
What Twitter image specs matter most?
Match 16:9 aspect ratio, keep one headline idea, use strong contrast, and leave safe margins. Readable type at thumbnail scale matters more than decorative detail.
Can I use an Open Graph image as a Twitter post image?
You can, but 1200 × 630 OG art is not optimized for the wide timeline card. For new post graphics, design at 1600 × 900 px on the X Post format.
Does FeatureImg post to X automatically?
No. FeatureImg exports the file. You upload or attach it in your normal posting workflow.
Create your next Twitter or X post image
Pick the twitter post size in pixels your timeline graphic needs, design for fast scrolling first, and keep copy short. When you are ready, start from the X Post format page, browse templates, or open the X Post editor preset to export a clean image.
