You want to start a subreddit. Maybe you have a niche hobby, a local community, or a business angle. Maybe you just want a space where the signal-to-noise ratio is better than the big subs.
Whatever your reason, the process is straightforward if you do it right. Most people skip the preparation and end up with a dead subreddit. This guide fixes that.
What you want to do: create a subreddit that people actually join, read, and participate in.
Before you start: you need a Reddit account that is at least 30 days old and has some comment karma. Reddit blocks new accounts from creating subreddits to prevent spam. If your account is fresh, spend a few weeks participating in relevant communities first. If you need guidance on setting up your account properly, check our detailed how to start a subreddit guide for the full account preparation checklist.
You also need a clear idea of what your subreddit will be about. Vague ideas fail. Specific ones grow.
Step 1: Check your account meets the requirements
Reddit requires:
– Account age: minimum 30 days (some sources say 7 days, but 30 is safer).
– Comment karma: at least 50–100. Post karma also helps, but comment karma is more useful for showing you understand community norms.
– No recent bans or suspensions.
If your account is new, you cannot skip this step. Do not try to create a subreddit with a day-old account. It will be blocked. If you need to build karma first, read our Reddit karma guide to understand how comment karma vs post karma works in practice.
Step 2: Plan your subreddit before you create it
Ask yourself:
- What specific topic or community does this serve? “Cooking” is too broad. “Cooking with cast iron for apartment kitchens” is specific.
- What rules will you need? Start with 3–5 essential rules. You can add more later.
- Who is the audience? Beginners? Experts? Locals?
- What kind of content do you want? Questions? Photos? Discussions? Links?
Write this down. It will save you from creating something nobody needs.
Step 3: Create the subreddit
On desktop (the mobile app has limited options here), go to your homepage, click “Create a community” in the left sidebar.
You will need:
– A name: short, memorable, relevant. No underscores if you can avoid them. Check it is not already taken.
– A description: 1–2 sentences explaining what the subreddit is for. This appears in search results.
– Community type: Public is the default. Restricted or private only if you have a specific reason.
– NSFW toggle: Only mark it if your content actually requires it. Marking a non-NSFW subreddit as NSFW reduces discoverability.
Click “Create community” once. Do not click again. Reddit may show a loading delay of a few seconds.
Step 4: Set up rules, appearance, and automod
Right after creation, set:
– 3–5 clear rules in the “Rules” section. Example: “No self-promotion”, “Be respectful”, “Posts must include a photo”.
– A welcome post explaining what the subreddit is for.
– A basic banner and icon. You can use a simple image. This matters for first impressions.
– Automod: add a basic rule to remove spam or low-karma posts. Reddit has a premade automod template you can edit.
Do not overcomplicate the rules. You can adjust later based on what actually happens.
Step 5: Add your first content (yes, you)
A subreddit with zero posts looks dead. Before you invite anyone, add 5–10 posts yourself. Mix content types:
– A welcome post.
– A discussion question.
– A link to a useful resource.
– A photo or example relevant to the topic.
This gives new visitors something to interact with immediately.
Step 6: Promote without spamming
Do not post “Join my new subreddit!” in unrelated communities. That is spam and will get you banned.
Instead:
– Mention your subreddit naturally in relevant discussions. Example: “There is a subreddit for that: r/YourSub”.
– Crosspost relevant content to larger subreddits (if their rules allow it).
– Share on other platforms where your audience already hangs out.
Growth is slow. That is normal. Focus on quality over quantity.
Common blockers and how to fix them
| Blocker | Why it happens | How to fix |
|---|---|---|
| “You cannot create a community” | Account too new or low karma | Wait 30 days, build comment karma first |
| No one joins | Subreddit is too broad or vague | Narrow the topic, add real content |
| Spam posts appear | No automod or rules | Add basic automod rules |
| People join but do not post | No clear starting point | Pin a welcome post and discussion thread |
Practical example: A subreddit for local plant swaps
Let us say you want to start r/CityNamePlantSwap.
- Account: 60 days old, 150 comment karma from r/houseplants and r/gardening.
- Plan: Local only, no selling, no shipping. Rules: “Must include city neighborhood in title”, “No money exchanges”, “Be nice”.
- Content: Post 5 photos of plants you want to swap. Write a welcome post explaining how it works.
- Promotion: Mention it in r/houseplants when someone asks about local plant trading. Crosspost a photo to r/plants.
- Result: 50 members in week one, 3 successful swaps. Slow but real.
Final takeaway
Starting a subreddit is not hard. Growing one is. The difference between a dead subreddit and a living one is preparation: having a specific niche, clear rules, real content, and patience. Do not rush the account requirements. Build your <!—SEO_INTERNAL:Reddit account setup —> first, participate honestly, and only create your community when you understand how Reddit actually works.
For this use case, practical proxy option for Reddit workflows should be compared by pricing, setup difficulty, support quality, refund policy, and whether it fits your workflow.
