Prerequisites#

  • A Reddit account that is at least 30 days old
  • Enough positive karma (Reddit does not publish the exact threshold, but a small amount of post/comment karma is typically sufficient)
  • A verified email address on your account

Creating the Subreddit#

  1. Go to reddit.com/subreddits/create or tap Create a Community from the left sidebar
  2. Fill in the required fields:
    • Name — the r/ handle. This cannot be changed after creation. Keep it short, memorable, and easy to spell.
    • Display Name — the human-readable title shown on the community page (can be changed later)
    • Description — a brief summary shown in search results and community cards
  3. Choose a community type:
    • Public — anyone can view and post
    • Restricted — anyone can view, but only approved users can post
    • Private — only approved members can view or post
  4. Mark the community as 18+ if the content warrants it
  5. Click Create Community

Initial Setup#

After creation, configure these settings from the Mod Tools panel:

Community Appearance#

  • Upload a community icon (256 × 256 px recommended) and banner (4000 × 192 px)
  • Set a color theme that reflects the community’s identity

Rules#

Define 3–5 clear rules early. Common starting rules:

Post and Flair Settings#

  • Create post flairs to help members categorize their submissions
  • Decide whether to allow link posts, image posts, polls, or text-only posts
  • Enable or disable user flair so members can tag themselves

AutoModerator#

Set up AutoModerator early to handle common moderation tasks:

  • Filter posts from new or low-karma accounts
  • Remove posts containing specific keywords
  • Auto-flair posts based on title patterns

Configure it at r/yoursubreddit/wiki/config/automoderator.

Growing the Community#

  • Seed content — post 5–10 quality posts before inviting others so the community does not look empty
  • Cross-post relevant content from related subreddits (follow their rules on self-promotion)
  • Engage — reply to every comment in the early days to build a culture of discussion
  • Recruit moderators once the community reaches a size where you cannot manage the queue alone
  • Set a posting schedule for recurring threads (e.g., weekly discussion, AMAs) to create predictable engagement points

Common Pitfalls#

  • Choosing a name that is too niche or too broad — a narrow name limits growth; a generic name attracts off-topic posts
  • No rules on day one — without clear rules, early norm-setting falls to whoever posts first
  • Over-moderating — removing too aggressively discourages participation. Start lenient and tighten as culture forms
  • Ignoring AutoModerator — manual moderation does not scale. Invest time in filters early
