How to use X Spaces: host, join, and grow with audio

#Quick answer

To use X Spaces, press and hold the compose button on mobile and tap the Spaces icon (or open Spaces from the left menu on x.com), name your Space, choose live or scheduled, and go. Anyone can host for free - the 600-follower rule was dropped in 2021. A Space holds up to 13 microphones (host, 2 co-hosts, 10 speakers) and unlimited listeners, and you can record a replay that lasts about 30 days.

#TL;DR

X Spaces is the live audio feature on X (formerly Twitter) - a drop-in room where a host talks, a handful of people speak, and everyone else listens in real time. It is free, open to any account, and one of the fastest ways to build a real relationship with an audience, because voice carries trust that a text post never will. The mechanics take two minutes to learn. The growth part - turning one Space into a week of content and a wave of new followers - is where most people leave value on the table. This guide covers both.

#How to host an X Space, step by step

The flow is nearly identical on iOS, Android, and the web:

1. Open the composer. On mobile, press and hold the compose (the blue write button) and tap the Spaces icon. On x.com, click Spaces in the left menu, then Create your Space.
2. Name it. Give the room a clear, specific title - "Cold email teardowns, live" beats "Marketing chat." The title is what people see in their timeline, so treat it like a headline.
3. Choose live or scheduled. Start now, or pick Schedule for later and set a date and time up to 30 days out.
4. Decide on recording. Toggle Record Space on if you want a replay. It is off by default, and you cannot turn it on after the fact, so decide before you go live.
5. Go live and invite speakers. Once you are in, tap the people icon to invite co-hosts and speakers, or approve listeners who tap Request to speak.

That is the whole setup. If the Spaces button is missing from your app, it is a build issue, not an account issue - host from x.com on desktop or update the app. All of this is documented on X's own Spaces help page.

#Who can be in the room: the limits that matter

| Role | Limit | What they can do | |---|---|---| | Host | 1 | Starts the Space, controls speakers, ends it | | Co-hosts | Up to 2 | Invite and remove speakers, manage the room | | Speakers | Up to 10 | Talk once the host brings them up | | Listeners | Unlimited | Listen, react with emoji, request to speak |

So a Space fits up to 13 microphones at once and an unlimited audience. Per Metricool's 2025 breakdown, you can also schedule up to 10 Spaces at a time and keep replays for about 30 days. Two co-hosts is the detail people forget: pulling in a co-host to manage requests and keep the conversation moving is the difference between a smooth room and you fumbling the controls mid-sentence.

#How to join and speak in a Space

Joining is even simpler. Live Spaces from hosts you follow appear as a purple bar at the top of your timeline. You can also join from a host's profile or a shared link. You always enter as a listener - silent to the room - and can leave any time without anyone noticing.

To get on the mic, tap Request to speak. The host or a co-host approves you, and you stay muted until they unmute you. Listeners can also drop emoji reactions, which is the low-effort way to signal you are there and engaged - useful, because hosts often scan reactions to decide who to invite up.

#Why Spaces are worth your time

Text on X is a firehose the X algorithm filters hard. Audio is different: for the length of a Space you have someone's full attention, and voice builds familiarity fast. That is why Spaces punch above their follower count for three jobs:

• Trust. People who hear you talk for 30 minutes are far more likely to follow, reply, and buy than people who scrolled past one post.
• Reach through the reminder. A scheduled Space posts a card people can tap to be reminded, and X notifies your followers when you go live - free distribution the feed rarely gives a single post.
• Relationships with bigger accounts. Co-hosting a Space with someone one tier above you is a genuine two-way collaboration, not a cold reply. It is one of the cleaner ways to borrow an audience.

If you are learning how to get followers on X, a weekly Space in your niche compounds faster than almost any posting tactic, because it turns passive followers into people who actually know your voice.

#Turning one Space into a week of content

Here is the part most "how to use X Spaces" guides skip. The Space is the smallest part of the value. The content around it is where the growth lives:

1. Announce it 24-48 hours out. Schedule the Space, then post the reminder card and pin it. Timing matters - line the start up with when your niche is online using the best time to post on X.
2. Record it. A replay lives ~30 days and keeps working while you sleep.
3. Harvest it. Pull the three sharpest moments into quote-posts, a short thread, or clips. One good hour of audio can feed a week of posts, which is exactly the repurposing habit behind most advice on how to make money on X and using X for business.

The bottleneck is never the Space. It is the follow-up: writing the announcement, the recap thread, and the replies to everyone who showed up, every week, without falling off by week three.

#Where the friction is (and how to remove it)

Running Spaces consistently means a steady stream of posts before and after each one - and that is the tax that kills most people's cadence. That is the gap X-Autopilot is built for: it drafts posts and replies in your voice from real Chrome on your own Mac, so the announce-recap-reply loop around each Space is approvals instead of blank pages. It will not host the Space for you, and it is not a sanctioned, risk-free path, since browser-route automation on X is a gray area rather than an approved one. Treat it as a way to keep the content habit around your Spaces alive, not a shortcut around showing up and talking. And when someone great drops into your room, reply to them well afterward - that follow-up is where a one-time listener becomes a regular.

Schedule your first Space for later this week, keep it to 20 minutes and one clear topic, and record it. The room does not need to be big. It needs to be real.
