How to Crosspost on Reddit: Steps, Rules, and Reach

A Reddit crosspost is Reddit’s feature for sharing a post from one community in another while showing a preview of the original. As of September 2026, Reddit’s Help Center calls it “reposting (formerly crossposting).” Choose an available community, adjust the title or flair if needed, and share only when the post fits its rules.

Key takeaways:

• Reddit’s current Help Center calls the feature reposting, while many users still search for crossposting.
• On desktop and iOS, choose Repost under the post. On Android, choose a community or your profile from the Post to menu.
• A destination can disable reposts and set its own rules, so check before you submit.
• A repost can give another audience a route to the original. It does not guarantee reach, votes, or karma.

What is a Reddit crosspost?

A Reddit crosspost shares an existing post in another community through Reddit’s Repost feature. The preview shows the original poster, community, and upvote score and lets readers find the source.

The destination still applies its own rules and decides whether that content belongs there. Reddit’s reposting help page documents the Repost and Share as post controls.

To share a comment, open the comment’s overflow menu and choose Share as post. Reddit documents that as a separate flow from Repost under a post.

To crosspost on Reddit, open the existing post, select Repost, choose a community, then adjust the title or flair if needed. Reddit’s current Help Center lists separate steps for reddit.com, iOS, and Android; on Android, the destination menu can also send the post to your profile.

Conceptual repost flow: choose the original post, select a community, then submit after checking its rules.

Which subreddits allow crossposting?

Not every subreddit accepts reposts. Reddit says a community that blocks previously posted content appears greyed out in the destination picker.

Each community can also set rules about topic fit, format, links, or promotion. Check those rules before you rely on the button being available.

A greyed-out destination is unavailable. An available destination still requires a rules check.

On Reddit’s desktop site, Reddit’s posting help page points to the rules in the right sidebar. In the mobile app, tap See more and then About.

Look for rules about reposts, original content, self-promotion, post types, title format, and required flair. Some communities also set account or karma requirements.

Reddit says those requirements vary by community; it does not publish one threshold that applies everywhere. An available repost option does not override a community’s rules or guarantee that moderators will leave the post up.

If the rule is unclear, ask the moderators before posting. If the community is greyed out, choose another relevant destination or skip the repost.

Do not treat a disabled option as a reason to copy someone else’s post manually around the restriction.

When should you crosspost a Reddit post?

Crosspost when a particular community has a reason to read the original post.

Reddit’s reposting guidance gives no ideal delay or fixed number of destinations.

Check that the information is still current and that you can answer replies.

Say you posted a comparison of two welcome-email subject lines in a founders’ community.

Later, you see a community discussing email copy.

Check whether Repost is available there and whether its rules permit the format and any promotional link in your original.

If members are asking about welcome emails, a repost with a title naming the comparison may help. If the rules require original posts, or the only attraction is a larger audience, skip it.

Reddit’s spam policy warns against mass-posting repetitive content for exposure or financial gain and repeatedly sharing old content for karma.

Does crossposting increase reach or karma?

A repost places a preview of the original post, including its author, community, and score, in another community. Reddit says relevant reposts may provide more exposure, but its guide to getting posts noticed says no method guarantees that a post will be noticed.

Karma is a separate question. Reddit’s karma guide says upvotes affect karma, but not one-to-one.

Its reposting guide does not explain exactly how karma is attributed between the original author and the reposter. The score in the preview identifies the original; it does not settle which account receives what karma from the repost.

If you want to learn from a repost, read the discussion in both places.

Did the destination ask different questions about the same post?

What should you check before and after crossposting?

Before submitting, use the destination picker and rules check above. Confirm that the original is still current, then add a clear title or required flair.

After submitting:

1. Check the destination thread. See whether the repost remains visible. If it is removed, read the moderator notice or message and follow that community’s process.
2. Answer substantive replies. If someone asks which audience each welcome-email subject line targeted, point to what the original says. If it does not say, acknowledge the gap.
3. Use the feedback. If readers need context that the original lacks, clarify it in the new discussion. If a moderator cites a rule, remember it before choosing that destination again.

After reposting, check the thread, read any moderator notice, and answer questions you can support.

Frequently Asked Questions

What does crossposting mean on Reddit?

A Reddit crosspost shares a post in another community through Reddit’s native repost feature. Reddit’s current Help Center calls it “reposting (formerly crossposting).” The preview includes the original poster, community, and score, so readers can see where the content came from.

How do you crosspost on Reddit desktop?

On Reddit’s desktop site, open the post and click Repost below it.

Choose a destination community, edit the title if needed, add flair when the rules require it, and click Post.

Reddit may grey out a community that does not accept content previously posted elsewhere.

How do you crosspost on the Reddit mobile app?

On iOS, tap the Repost icon under the post, choose a community, then tap Post.

On Android, tap Repost, select a community or your profile in the Post to menu, adjust the title or flair if needed, and submit. Check the destination’s rules first.

Why can’t I crosspost to a subreddit?

The destination may disable reposts, in which case Reddit greys it out in the community picker.

Other restrictions can come from community rules, post format, or account eligibility.

Review the sidebar on desktop or See more > About in the app, and ask moderators if the rule is unclear.

Can I crosspost the same post to many subreddits?

Reddit does not publish a universal number of communities for one post.

Choose a destination because the material fits its audience, and follow each community’s rules.

Mass-posting repetitive content for exposure or financial gain can violate Reddit’s spam policy, so avoid broad copy-and-paste distribution.

Does a Reddit crosspost give karma to the original poster?

Reddit says votes influence karma, but karma only approximates votes and does not map one-to-one. Its reposting help page shows the original author and score but does not spell out exact karma attribution between the person who reposts and the original poster. Do not promise a specific karma result.

Does crossposting increase reach on Reddit?

Reddit says reposting relevant content may provide more exposure, but it also says no tactic guarantees that a post will be noticed. A crosspost creates another path to the source; it cannot guarantee views, upvotes, a Hot ranking, clicks, or conversions.
