VisionWhat are the best content formats for X growth?
The best content formats for X growth are short text posts and images, backed by threads for depth. Buffer's 2026 study found text posts on X had the highest median engagement rate at 3.56%, ahead of images at 3.40%, video at 2.96% and link posts at 2.25%. Polls and replies round out a strong mix.
Ask ten growth accounts which format works best on X and you'll get ten answers. One swears by threads. Another only posts videos. A third says plain text is all you need. They can't all be right, can they?
Here's what I find interesting: they can be partly right, because each format does a different job. Some formats win engagement, some build trust, and some bring new followers. Once you know which is which, you can build a mix that grows your account on X (formerly Twitter) instead of guessing.
What does the data say about the best format on X?
The clearest recent data says plain text leads on X. Buffer's 2026 content format study ranked text first by median engagement rate, with images close behind.
| Format on X | Median engagement rate (Buffer, 2026) |
|---|---|
| Text | 3.56% |
| Image | 3.40% |
| Video | 2.96% |
| Link | 2.25% |
A quick caveat. These figures come from posts sent through Buffer, so they reflect Buffer's users, and they use Buffer's own method. Don't compare them with benchmark reports that divide by follower count. They measure different things.
That said, the result matches how X works. People come to X to read short takes fast. A sharp sentence is native to the platform in a way a long video often isn't.
Format 1: Short text posts
Short text posts are the backbone of growth on X. They're fast to write, easy to read and easy to reply to, which is exactly what the ranking system looks for.
X's open-source For You algorithm code scores posts by predicted actions such as replies, reposts, likes, shares and dwell time. A clear opinion or useful tip in one or two sentences invites all of those. On a free account you have 280 characters, and most strong posts use far fewer.
Best for: daily posting, opinions, tips, questions. Our guide on what to post on X every day gives you a menu of text post types.
Format 2: Images and screenshots
Images come a close second, and they're the easiest way to stop the scroll. Screenshots of real work, charts and before-and-after shots add proof that text can't.
X lets you attach one to four photos to a post. Use images that explain something: a result, a process, a quote with your note on top. Avoid stock photos that add nothing.
Best for: proof, data, tutorials, behind the scenes.
Format 3: Threads
Threads are how you show depth on X. They don't appear as a separate category in the Buffer table, since they're built from text and image posts, but they're the format that turns casual readers into followers.
A good thread teaches one thing in five to ten posts, each one strong enough to stand alone. When a thread reaches four or more posts, X truncates it behind a "Show this thread" link, so the first post carries the load. Our guide on how to write viral Twitter threads covers hooks and structure, and our free thread maker splits a draft into posts for you.
Best for: how-tos, breakdowns, stories, lists.
Format 4: Video
Video ranks third in Buffer's data on X, but it can still pay off when it shows something text can't. Demos, short explainers and clips from talks are where video earns its place.
According to X's help page on videos, accounts without a paid subscription can upload videos up to 140 seconds long and 512MB in size. Subscribers can upload multi-hour videos, though X's help pages give different exact limits. For growth, shorter is usually safer. Add captions, since many people scroll with sound off.
Best for: product demos, tutorials, personality.
Format 5: Polls
Polls are the lowest-effort way to get people interacting with your account. One tap is all it takes, and the results often spark replies.
X's help page on polls says a poll can have up to four options of 25 characters each and run from 5 minutes to 7 days. Votes are private. Ask questions your audience has real opinions on, then post a follow-up with what you learned.
Best for: audience research, light engagement, content ideas.
Format 6: Link posts
Link posts came last in Buffer's data, so use them sparingly and give them context. Whether X actually reduces the reach of links is disputed.
X's head of product has publicly denied that link posts are penalized and advised people to post the link with enough context about what readers will see. Many creators still believe links get less reach. I'd follow the practical middle path: write a post that stands on its own, add the link, and say why it's worth the click. Our guide on how to improve X post reach covers the other levers.
Best for: sending people to your newsletter, product or long article.
Format 7: Articles and longer posts
X Articles let paid subscribers publish long-form pieces with headings, images and embedded posts. Anyone can read them. They're useful once you have an audience that wants depth.
X's own Help Center guide to Articles suggests pinning new Articles for the first 24 to 72 hours and sharing excerpts as threads. Which plans include Articles differs between X's help pages, so check that page for your tier. If you already write a blog, our guide to repurposing blog content into tweets shows how to reuse it.
How to mix formats for steady growth
A strong weekly mix leans on text, adds images and one thread, and uses video, polls and links as seasoning. Here's a simple split for about ten posts a week:
- 5 short text posts (tips, opinions, questions)
- 2 image posts (screenshots, charts, proof)
- 1 thread (your best idea of the week)
- 1 poll or short video
- 1 link post with context
Then measure. Compare each format's views and replies against your usual, not against other people. I built a free extension, XVision, whose dashboard rates each of your posts against your usual views, so you can see which formats beat your average.

Pick the format that fits the idea
The best content format for X growth is the one that carries your idea most clearly. Start with text, add images for proof, write one great thread a week, and test the rest. You'll find your own winning mix within a month, and it'll be built on your data, not someone else's hunch.
Frequently Asked Questions
Do videos get more reach than text on X?
No, videos do not automatically get more reach than text on X. Buffer's 2026 study found text posts had a 3.56% median engagement rate on X, compared with 2.96% for video. Video still works well for demos and tutorials, where showing beats telling, so test it against your own text posts.
Are threads still worth it on X in 2026?
Yes, threads are still worth it on X in 2026 for teaching and storytelling. Buffer's 2026 creator playbook calls threads one of the best ways to hold attention on X. X truncates threads of four or more posts behind a "Show this thread" link, so a strong first post matters most.
Does X reduce reach for posts with links?
Whether X reduces reach for posts with links is disputed. X's head of product denied a link penalty in April 2026 and advised adding context before the link. Buffer's 2026 data still shows link posts with the lowest median engagement rate on X, at 2.25%, so give every link a strong standalone post.
How many images can I add to a post on X?
You can add one to four images to a single post on X, according to X's Help Center. Photos can be up to 5MB each. A post can also hold a GIF or a video, with up to four media items in total, which works well for before-and-after comparisons or step-by-step screenshots.
What format should a brand new X account start with?
A brand new X account should start with short text posts and replies. Text is fast to write, earned the highest median engagement rate in Buffer's 2026 study, and helps you find your voice. Add one image post and one short thread each week once posting daily feels comfortable.
