How to Post on X (Twitter): User Guide to Publish Different Types of Content (2026)

To post on X (formerly Twitter), open x.com or the X mobile app, tap the compose button, type your message (up to 280 characters on free accounts or 25,000 with X Premium), and tap “Post”. You can schedule posts for later using the calendar icon in the composer.

That’s the quick version of how to post on Twitter. Most people searching for this already know the platform exists. What they don’t know is how to tweet effectively across 8 distinct content types, each with its own specs and algorithmic treatment. Getting the format wrong tanks your reach before you’ve finished typing.

Text posts. Images. Video. GIFs. Polls. Threads. Long-form articles. Community posts. This guide covers how to post a tweet on Twitter for every format, with exact limits and step-by-step instructions for web and mobile. It also covers what changed in 2025 and 2026: the link visibility penalty that made external URLs invisible for free accounts, the private likes shift, and the long-form features that finally gave threads some competition.

X still has roughly 557 million monthly active users as of early 2026. Agencies and freelancers managing client accounts should care because it’s one of the few platforms where a well-written text post still outperforms video. Knowing how to post on X well (not just where the button is) separates accounts that grow from accounts that shout into the void.

If you manage multiple client accounts across X and other platforms, RecurPost handles scheduling, post variations, and approvals from one dashboard.

How to Post on X (Twitter) from the Web

Open x.com, click the compose box at the top of your Home timeline, type your post, and click Post. That’s how to tweet from a desktop in about 10 seconds.

The full process:

1. Go to x.com and log in.

2. Click the “What is happening?” compose box at the top of your Home feed. The “Post” button in the left sidebar does the same thing but opens a pop-up window instead.

3. Type your message. The circular character counter turns orange at 260 characters and red at 280.

4. Attach media if needed: photos, GIFs, a poll, or emoji.

5. Click Post.

Ctrl+Enter (or Cmd+Enter on Mac) publishes without clicking the button. Small thing. Adds up when you’re moving through 10 client accounts back to back.

There is a difference between the two composer options. The sidebar Post button opens a floating window. It stays visible when you scroll your feed. It disappears once you scroll past it. If you’re referencing another post while drafting, the floating window is more practical.

You can tag other accounts by typing @ followed by their handle. Mentions show up as clickable links and send a notification. Agencies tag partner brands or business accounts in client posts. It is an easy way to start a conversation without cold-direct messaging (DMing).

How to Post on Twitter Mobile (iOS and Android)

Tap the ‘+’ button at the bottom-right of the X app. Type your content and tap ‘Post’.

The process:

1. Open the X app on iOS or Android.
2. Tap the ‘+’ button in the bottom-right corner.
3. Type your message in the “What is happening” section
4. Attach media by tapping the image icon (camera roll), GIF icon, or poll icon below the text field.
5. Tap Post in the top-right corner.

The microphone icon on your keyboard lets you dictate posts instead of typing. It’s a quick way to post on X between client meetings.

iOS and Android look almost identical for posting. The gap that matters: you can’t schedule posts from the X mobile app. The native scheduler is for web access only. You need to keep a x.com web browser always open if you schedule from your phone every day. RecurPost’s mobile app handles post scheduling for iOS and Android.

A trick worth knowing: swipe down on the mobile composer to save your post as a draft. Drafts sync between your phone and desktop. Start something on the train and polish it at your desk later.

You can click in-app photos or capture videos from the camera icon inside the composer. You don’t have to switch apps. Handy for real-time event coverage on client accounts.

Character Limits and Account Types on X

Free X accounts can post up to 280 characters. X Premium subscribers get 25,000 characters. That’s roughly a 4,500-word article published on the platform.

Users get confused with the counting rules on X. URLs take exactly 23 characters, no matter how long the link. X wraps everything through its t.co shortener, so a 10-character URL and a 200-character URL cost the same. Emojis take 2 characters each because of Unicode encoding. Media (images, GIFs, videos, polls) don’t count at all. You keep the full 280 for text, even with 4 photos attached. But @mentions do count, so tagging 5 accounts in one post burns through your budget fast.

The account tiers break down like this:

That 10x reach number isn’t marketing spin. A 2026 analysis of 18.8 million posts across 71,000 X accounts measured it. Premium accounts get roughly 10x the distribution of free accounts. The gap got worse after March 2025, particularly for posts containing links.

The Premium decision for client accounts comes down to one thing: whether the client needs to share external links on X. If yes, Premium is close to mandatory. Text and image posts still reach audiences on free accounts. Link posts from free accounts now get close to zero distribution.

How to Post Images on X (Twitter)

Click the image icon in the compose box, select up to 4 photos, and X arranges them in a grid format.

From the desktop web version:

1. Open the composer (compose box or sidebar Post button).
2. Click the image icon (mountain/landscape icon) in the toolbar.
3. Select 1 to 4 images.
4. Click the ALT badge on each image to add a description (up to 1,000 characters).
5. Type your text and click Post.

From the mobile app:

1. Tap + to open the composer.
2. Tap the image icon to pull up your camera roll.
3. Select up to 4 images.
4. Tap the ALT badge on each to add a description.
5. Tap Post.

X accepts JPEG, PNG, GIF, and WebP. Max file size is 5MB per image.

The cropping catches people off guard. X reshapes images to fit its timeline grid, and where it crops depends on how many images you’re posting. A single image displays best at 1200 x 675 px (16:9) or 1080 x 1080 px (square). Two images sit side by side at roughly 7:8 each. Three images put one large image on the left with two stacked on the right. Four images form a 2×2 grid at roughly 2:1 per image. If your dimensions don’t match, X crops from the center. A client’s logo or headline text sitting at the edge of the frame? Gone. Preview before posting.

Most agencies know they should be adding alt text. Most skip it when they’re busy. That’s a mistake for two reasons. First, roughly 2.2 billion people globally have some form of vision impairment. They rely on screen readers. Second, alt text gives X’s algorithm context about what’s in the image. That context affects who sees the post. Ten seconds per image. That’s all it takes.

How to Post a Video on X(Twitter)

Free accounts can upload videos up to 2 minutes and 20 seconds long. Premium subscribers get up to 4 hours on web and iOS. Android is still capped at 10 minutes for Premium users. This oddity is not explained.

To upload:

1. Open the composer.
2. Click or tap the media icon.
3. Select your video. Only MP4 and MOV work. Nothing else.
4. Wait for the upload to process. A 500MB file takes a few minutes.
5. Add text and click Post.

X (Twitter) Video Specification

You can find these specs on X’s official media upload documentation for reference.

Failed video uploads on X are one of the most common agency problems. Wrong codec (X wants H.264, not H.265/HEVC), file too large, or corrupted headers from a bad export are common reasons. RecurPost catches over 850 types of post failure errors, many specific to X video encoding. That matters when you’re scheduling 50 client videos a week and can’t monitor each one manually.

Most people scroll X with sound off. A video without captions loses its audience before the 2-second mark. Burned-in text or X’s auto-generated subtitles fix this. Always add them for client accounts.

Format matters more than production quality. Square (1080×1080) and vertical (1080×1920) videos take up more feed space than landscape. More screen means a higher chance someone pauses their scroll. Landscape video gets squeezed into a thin strip that’s easy to thumb past.

Then there’s the 3-second rule. X’s algorithm watches whether viewers keep watching or scroll away in the first few seconds. If they leave, the algorithm stops showing the video to more people. Skip the branded intro. Get to the point in the first frame.

And the part that surprises most agencies coming from Instagram or TikTok: text posts actually outperform video on X. A 2026 study of over 18 million posts measured roughly 30% more engagement on text-only posts compared to video. Don’t assume video wins everywhere. On X, words still carry more weight.

For longer walkthroughs or tutorials, breaking the video into shorter clips posted as a thread often outperforms a single long upload. Each post in the thread earns its own engagement signals. One long video gets a single shot.

You can download Twitter videos. Repurpose for client content on different platforms.

How to Post GIFs and Polls on X (Twitter)

How to Post GIFs on X

X has a built-in GIF search powered by Tenor. Click the GIF icon in the composer, search for a keyword, and pick one.

You can upload your own GIF file the same way you’d upload a photo. Custom GIFs can be up to 5MB. One per post. You can’t mix a GIF with static images in the same post.

GIFs work well as reply content. A branded reaction GIF in a client’s niche makes the account feel like a person instead of a corporate logo. Some agencies use Giphy’s brand channel to create custom GIFs that show up in X’s built-in search. Low effort, ongoing visibility.

How to Post Polls on X

Click the poll icon (bar chart) in the composer and fill in your question.

1. Type your question in the main text field (uses your 280-character limit).
2. Add 2 to 4 options. Each allows 25 characters.
3. Set the duration: 5 minutes to 7 days. Default is 1 day.
4. Click Post.

Votes are anonymous. People who vote see results immediately. Everyone else waits until the poll closes.

No agency uses poll posts on X daily. However, practice shows that polls get more algorithmic signal than regular posts. A simple “A or B?” question invites replies and quote posts. Those interactions feed the algorithm. Polls also double as free audience research. Don’t guess what content the clients’ audiences want. Ask them upfront. Use 7-day durations for strategic questions and 24 hours for quick engagement plays.

How to Post a Thread on X (Twitter)

Tap the + icon below your first post in the composer to add another. Tap Post all to publish the full sequence at once.

1. Open the composer.
2. Write your first post.
3. Click + in the bottom-right. A second text field appears.
4. Keep adding posts until the thread completes.
5. Click Post all to publish everything together.

Each post follows the same character limit as a standalone one (280 free, 25,000 Premium). You can attach images or videos to individual posts in the thread.

The length of a thread matters less than the quality of the first post. A 3-post thread with high-value information works better than a 15-post thread. Nobody taps “Show more” if the hook is boring.

The first tweet thread needs to make users think, “I want to read the rest of this.” Interest stats, contrary beliefs, specific facts. Knowing how to write a tweet that hooks people is a valuable skill. Agency teams want such experts who can hook the audience in the first line.

Write each post so it makes sense on its own. People share individual thread posts all the time. If post 4 requires reading posts 1 through 3 to land, fewer people share it.

The last post should tell people what to do next: follow, reply with their take, or check a link in the replies. Not in the post itself. Link posts get penalized. A reply containing a link doesn’t carry the same penalty.

Numbering is optional. “1/” at the start, “(thread)” in the text, a 🧵 emoji. Whatever matches the client’s voice. Consistency matters more than the specific format.

Threads are the best format to turn long-form content short. X distributes such client content. Turn a 1,500-word blog into 5 posts. Distribute sections in each post. Every post gets its own engagement. That’s 5 chances at the algorithm instead of 1.

Read our full guide to creating Twitter threads for more on thread structure.

How to Post Long-Form Content on X (Twitter)

X Premium subscribers can write posts up to 25,000 characters with rich formatting: bold, italic, headings, and inline links.

These posts appear in feeds as truncated previews with a “Show more” link. Followers see the first couple of lines. That’s your pitch. Nobody will click if you write the interesting facts 3 paragraphs below.

To write one:

1. Open the composer on the web (mobile doesn’t support long-form formatting yet).
2. Type past 280 characters. The composer auto-switches to long-form mode.
3. Format with the toolbar: bold, italic, headings, and links.
4. Add inline images if needed.
5. Click Post.

The harder question isn’t how to create a long-form post. It’s when to use one instead of a thread or a blog link.

That bottom row is the one that reshaped X’s content strategy for agencies. A 2026 study of 18.8 million posts confirmed it: non-Premium accounts posting links now see 0% median engagement. The algorithm stopped showing those posts to anyone.

So long-form posts and threads are the only reliable ways to share substantial content on X without paying for Premium. For client accounts that need to publish industry analysis or thought leadership, long-form posts keep readers on the platform (which the algorithm rewards) without triggering the link penalty.

Worth noting: even Premium accounts take a hit on link posts. They average 0.28% engagement on links compared to 0.90% on text. Native content wins across every tier. Links are just less punished when you’re paying.

How to Post in X Communities

X Communities are topic-based groups where posts are visible only to members.

They work like forums nested inside X, each with its own rules and moderators. What you post in a community stays in that community. It doesn’t appear on your timeline unless community settings explicitly allow it.

To post:

1. Go to a community you’ve joined (search bar or Communities tab in the sidebar).
2. Click the compose button on the community page.
3. Write your post. Check the pinned rules first.
4. Click Post.

Community posts support everything regular posts do: text, images, video, GIFs, polls.

Some communities let anyone post immediately. Others need admin approval. Don’t get your client’s post removed for breaking community rules. That kind of visibility deflects algorithms. Read the rules.

Almost nobody is using Communities strategically. That’s the gap. A real estate agency joining local property communities on X puts client content directly in front of people who choose to be in that group. A SaaS company posting in marketing or tech communities reaches potential customers who already care about the topic.

The audience self-selected. You didn’t have to fight the main feed algorithm to reach them.

Use a strategy. For example, join niche X Communities. Post in the community daily. You will get high visibility and engagement. You don’t need to spend on ads or Premium.

How to Schedule Posts on X

X has a built-in scheduler on the web. Click the calendar icon in the composer, pick your date and time, and click Confirm.

Native scheduling step by step:

1. Open the composer on x.com. Only for desktop. The mobile app doesn’t support scheduling.
2. Write your post and attach media.
3. Click the calendar icon in the bottom toolbar.
4. Set date, time, and time zone.
5. Click Confirm, then Schedule.

You can review the official posting guide on X’s help center for the latest interface details.

Your scheduled posts stay in the “Scheduled” tab in Drafts. You can edit or delete them anytime before they publish.

For a single personal account, the native scheduler does the job. For agencies? It doesn’t come close. No bulk upload. No way to post across different platforms. No recurring content. No approval queue. No scheduling from mobile. No post-failure recovery. If a scheduled post fails to go live, you find out when a client asks why nothing went up on Tuesday.

A dedicated scheduling tool fills those gaps:

Tweet variation row matters on X. Agencies that recycle evergreen content (tips, quotes, promotional posts) run into a problem: X’s duplicate filters flag identical repeated posts. RecurPost rotates through different text variations each time it republishes from a content library. Same core message, different wording each time. The duplicate filters don’t trigger.

Managing X alongside Instagram, LinkedIn, Facebook, and TikTok from separate dashboards eats hours every week. One tool handling all of them cuts that down significantly.

How to Repost, Quote Post, and Reply on X (Twitter)

Reposting shares someone else’s post to your followers with one tap. Quote posting wraps the original in your own commentary.

X Reposting (formally Retweet)

1. Click the repost icon (two arrows in a loop) below any post.
2. Select Repost.

It shows up on your timeline without any added text. A one-click endorsement.

Quote Posting

1. Click the repost icon.
2. Select Quote.
3. Write your take above the embedded original.
4. Click Post.

Straight reposts say, “Look at this.” Quote posts say, “here’s our thoughts on this.” For client accounts, the second version is almost always the better move. It builds the brand’s voice. It gives people a reason to follow the client’s account rather than the original poster. Quote posts also look different in the feed. The commentary sits above the embedded post, so your text gets read first.

Replying

1. Click the speech bubble icon.
2. Type your reply.
3. Click Reply.

Replies show up under the original post and on your profile’s Replies tab. The algorithm gives replies disproportionate weight. A 2026 analysis of over 18 million Twitter posts found that a reply you respond to carries 75x more algorithmic weight than a like. One genuine back-and-forth conversation under a client’s post does more for distribution than 75 people tapping the heart.

That makes active replying the highest-return activity on X for agencies. Higher return than publishing new posts, even. Budget 15 to 20 minutes per client account per day for it.

Bookmarking and Likes

The bookmark icon saves a post privately. The heart icon likes it. Since 2025, likes are private by default. Nobody can see what you’ve liked. That killed a common agency tactic: checking what competitor accounts were engaging with. The data isn’t visible anymore.

How to Post on X (Twitter): 2026 Best Practices

The highest engagement on X in 2026 falls between 12 PM and 6 PM on Tuesdays, Wednesdays, and Thursdays. It is a 2026 analysis from 2 billion engagements across 307,000 profiles worldwide. Financial services see peak activities on Tuesdays and Thursdays in the morning from 8 AM to 1 PM. Tech and software perform best midday through the afternoon. Our best times to post on X guide breaks down the industry-specific windows.

Post 1 to 5 Times Per Day

X rewards consistency. A client posting 3 times daily on a predictable schedule gets more distribution than one dumping 10 posts on Monday and going dark. The algorithm notices irregular accounts and deprioritizes them. The algorithm notices irregular accounts and deprioritizes them. Pick a cadence each client can actually sustain. Stick to it.

Use 1 to 2 Hashtags Per Post

This is the opposite of Instagram. On X, more than 2 hashtags per post hurts engagement. X’s own data confirms this. The sweet spot is 1 or 2 relevant tags. Everything beyond that looks spammy to both the algorithm and the audience.

Work Around the Link Penalty

The biggest shift in X strategy since the rebrand. Since March 2025, non-Premium accounts posting external links get 0% median engagement. Not low. Zero. A study of 18.8 million posts across 71,000 accounts confirmed this.

What actually works instead:

1. Post your content as text or a thread. Put the link in a reply, not the post itself. The parent post gets a normal distribution. The link lives one tap away.
2. Turn blog posts into threads or long-form X posts. Share native content. The algorithm treats it in a different way from a link that redirects.
3. Pair images or video with a text CTA: “link in reply” or “link in bio.” Visual posts still get reach on free accounts.
4. For clients where link traffic is the whole point, upgrade to X Premium. Premium accounts get 0.28% engagement on link posts. Not impressive on its own. Something is better than nothing.

Reply to Every Reply

Conversations are the strongest signal the X algorithm tracks. When a follower comments on a client’s post, and you reply, that exchange carries 75x more weight than a like. Try to reply to every client account for 15 minutes daily. You will get 3x post reach. Budget for engagement, not content.

Test Text Against Video

Agencies default to video because Instagram and TikTok trained them to. X doesn’t work the same way. A 2026 analysis of 18 million posts shows that text-based tweets are better than videos. Text posts get 30% more engagement on X. Don’t carry assumptions from other networks. Test text, images, and video separately for each client. Let the data decide.

Write for Scroll Speed

A person on X reads the first line of a post and decides in less than a second whether to keep going. The rest of the post is invisible if the opener doesn’t land. Keep sentences short. One idea per post. Put the context in sentence two. Sentence one is the audition.

Understanding how the X algorithm works in 2026 helps you rank your content. Find the right content types and posting patterns for each client account.

How to Post on X (Twitter): Start Posting

X has more content formats than it did a year ago. Most agencies are still treating it like a text-and-link platform. That worked in 2023. It doesn’t anymore.

The accounts growing right now post native content in every format X supports. They show up in replies. They schedule on a regular basis instead of posting in bursts. Users post links twice a week and wonder why engagement metrics are 0.
