How to Create a Subreddit
The form is trivial. The empty room on the other side of it is not.
On desktop, go to reddit.com/subreddits/create or use the plus menu and choose Community. Pick a name, a description and a type, and it exists.
The requirement that stops people: your account needs to be at least 30 days old and have some karma. Reddit does not publish the karma figure and it has changed, but a brand-new account cannot create a community.
The name is permanent. Subreddits cannot be renamed, and the only route to a different name is creating another and moving everybody by hand.
After that you have a community with one member, which is the actual problem.
The empty-room problem deserves most of the attention here, because creating the subreddit is five minutes and the first hundred members can take a year.
Reddit does almost nothing to help a new community. There is no suggestion engine pushing small subreddits at people, no onboarding flow that surfaces them, and the search ranks by size and activity, so a community with nothing in it is unfindable by the people who would want it.
What brings the first members is a link from somewhere else — a comment in a larger related subreddit, a mention in a Discord, a post on another platform. Every successful small community was seeded from somewhere that already had people.
The second thing that works is posting as if the community already existed. Ten substantial posts before you invite anybody means the first visitor sees a place with something to read instead of a form asking them to start a conversation with nobody.
And the thing that reliably kills one: promoting it in larger subreddits. Most ban subreddit promotion explicitly, moderators remove it on sight, and doing it repeatedly gets the account suspended. The exception is communities with a weekly thread for exactly this, which a handful of large subreddits run.
It is slow, and the slowness is the point at which most people abandon it. A subreddit with two hundred genuinely interested members is worth more than a Page with twenty thousand followers who never see a post, and it takes about as long to build as that comparison implies.
The form, and what is permanent
The creation page asks for a name, a description, and a community type.
The name cannot be changed. Ever. Choose something that will still make sense if the community grows past the subject you started with.
The type can be changed later. Public means anybody can see and post; restricted means anybody can see and approved users can post; private means only approved users can see anything at all.
Starting restricted is a reasonable choice while you are seeding, because it stops the first content being spam, and switching to public later takes one click.
The account requirements
Your account must be at least 30 days old. This is firm and there is no appeal.
It also needs karma, and Reddit does not publish the threshold. Comment karma counts, and it is accumulated by replying usefully in existing communities — which is the same activity that will later bring you your first members, so it is not wasted time.
A verified email helps and may be required.
There is also a limit on how many subreddits one account can create in a period, which stops anybody spinning up dozens.
Setting it up before anyone arrives
Write the sidebar description as if explaining the community to somebody who arrived by accident. It is the only context a first-time visitor gets.
Write three to five rules. More than that is unenforceable and reads as hostile; none at all means every removal looks arbitrary.
Set up AutoModerator, even minimally. A rule that removes posts from accounts under a few days old handles most spam without any human attention, and spam is the single thing most likely to kill a small community's credibility.
And pin a post explaining what belongs here. It does the job of a hundred removal messages.
Getting the first members
Post ten things first. A visitor who finds a community with content stays; one who finds an empty page leaves and does not come back.
Link to it where the people already are — a reply in a larger subreddit where it is genuinely the answer to somebody's question, a Discord, a forum, a newsletter.
Check whether related large subreddits run a weekly promotion thread. Several do, and that is the one sanctioned route.
Do not mass-message people. Reddit treats unsolicited invitations as spam and it is one of the faster ways to get an account suspended.
Why the member count is the thing people judge
A visitor deciding whether to subscribe sees three things: the member count, the online count, and whether the top posts are recent.
The member count is the largest of the three and it is read as whether this place is real. Below a few hundred, most visitors do not subscribe regardless of the content, because a community that small looks like it will not be there next month.
That is the loop that makes the beginning so slow, and it is structural rather than anything about the subject.
It also means the online count matters more than people expect. Reddit shows it prominently, and a subreddit with members but nobody online reads as abandoned even when it is not.
Questions people ask about starting a subreddit
What do I need to create a subreddit?
An account at least 30 days old with some karma. Reddit does not publish the karma figure, and a brand-new account cannot create a community.
Can I rename a subreddit later?
No. The name is permanent. The only route to a different one is creating a second community and moving members by hand.
How do I get the first members?
A link from somewhere that already has people, and ten posts of content before anybody arrives. Reddit does not surface new communities on its own.
Can I promote my subreddit in bigger ones?
Only where there is a weekly thread for it. Most larger subreddits ban promotion and remove it on sight, and repeating it gets accounts suspended.
Should it start public or restricted?
Restricted is sensible while seeding, because it keeps the first content under your control. Switching to public later takes one click.
Why does nobody subscribe?
Below a few hundred members, most visitors do not subscribe regardless of content, because the size reads as a community that will not last.
