Clubhouse Specifications

Profile Photo

Dimensions	400 × 400 px recommended
Aspect Ratio	1:1
Max File Size	10 MB
File Formats	JPG, PNG
Notes	Displayed as a circle in rooms and the member directory. Second-pass check (direct full-text read of the official Personalization article, plus archive/App Store angles) still found no published px/MB spec — Clubhouse genuinely does not document this number anywhere public. Figures remain a commonly-cited industry estimate, unverified against an official source

House Photo

Dimensions	400 × 400 px recommended
Aspect Ratio	1:1
Max File Size	10 MB
File Formats	JPG, PNG
Notes	Avatar for a Clubhouse House (Clubhouse retired the original "Clubs" feature — the Knowledge Center now organizes communities under Friends & Houses, with no Clubs section remaining). Displayed as a circle; second-pass direct read of the official Creating Houses article confirms it still does not publish px/MB specs — unverified against an official number

Room Background

Dimensions	1500 × 500 px recommended
Aspect Ratio	3:1
Max File Size	10 MB
File Formats	JPG, PNG
Notes	Optional background image for a scheduled or live audio room. Second-pass check: full-text read of all four current official Live Rooms articles ("Creating Live Rooms," "What are Live Rooms," "Live Rooms in your Hallway," and the Live Rooms category page) plus a general web search turned up zero mentions of a room background/cover-image option anywhere in Clubhouse's current documentation or 2025–2026 coverage. This strengthens the case that it is a legacy/deprecated field carried over from an older app version — treat this spec as likely obsolete, though outright removal cannot be 100% confirmed since Clubhouse doesn't publish feature-deprecation notices

Live Audio Room

Notes

Real-time audio room. Clubhouse's current Knowledge Center does not publish an official listener cap (reconfirmed: neither "Creating Live Rooms" nor "What are Live Rooms" mention a number). Second-pass web search found current (2024–2026) secondary/blog sources consistently citing 5,000 as the room capacity figure — not the ~8,000 post-Elon-Musk-incident figure previously assumed here — but no official Clubhouse source (help center, blog, or press) was found publishing any specific number in this pass either. Treat any specific listener figure as unverified; 5,000 appears to be the more commonly repeated current estimate, not 8,000. Uses compressed real-time audio (originally built on the Agora SDK, which uses the Opus codec); this codec detail still has not been re-confirmed by a current official source after a second search pass

Replay / Recording

Max File Size	500 MB
File Formats	MP3, M4A
Notes	Recordings of rooms can be saved and shared as audio files. Clubhouse's official "Replays" support article (reconfirmed via second-pass direct full-text read) only describes a "download full audio" option for room creators — it does not name a specific export format (not literally "MP3" or "M4A" anywhere in the text) and publishes no file-size cap. The 500 MB / MP3 / M4A figures remain unverified against an official source; the format names in particular could not be corroborated at all this pass

House (Group Chat Audio)

Notes

Clubhouse's "Clubs" feature has been retired and replaced by "Houses" (per the current Knowledge Center, which has a Friends & Houses category and no Clubs section). Per Clubhouse's official "Creating Houses" article, a House can invite up to 25,000 members — not 100. Houses can contain their own private House Rooms (live audio, visible only to members) and House Chats (text/async). Users can create up to 5 Houses per week

Display Name

Character Limit	30 characters
Notes	Not published in exact numeric form by Clubhouse's own Help Center (which only documents a 14-day cooldown between name changes); the 30-character figure is a widely repeated third-party estimate, not independently confirmed against a second current, dated source

Username

Character Limit	15 characters
Notes	Unique handle; letters, numbers, underscores. Case-sensitive; can only be changed once every 14 days (confirmed via Clubhouse's official Personalization article). The 15-character figure itself is a widely repeated third-party estimate, not independently confirmed against a second current, dated source

Bio

Character Limit

Not officially specified

Notes

Clubhouse's official Personalization support article (reconfirmed via second-pass direct full-text read) describes the bio feature but publishes no character limit. Third-party testing is inconsistent: some sources now claim no enforced limit at all, others report the field cutting off in the low thousands of characters (roughly ~2,400 in one informal test). The previously listed "3000" figure could not be corroborated by two independent current sources in this pass either — treat any specific number here as an unverified estimate, not a confirmed platform limit

Room Title

Character Limit	60 characters
Notes	Clubhouse's official "Creating Live Rooms" article (reconfirmed via second-pass direct full-text read: it says users can "Add a room title" during setup) confirms a room title field exists but still does not publish a character limit; the 60-character figure remains an unverified third-party estimate

House Name

Character Limit	32 characters
Notes	Clubhouse's "Clubs" feature has been retired and replaced by "Houses." The official "Creating Houses" article (reconfirmed via second-pass direct full-text read) confirms House names cannot contain special characters but still does not publish a numeric character limit; the 32-character figure (carried over from the old Club Name spec) remains unverified for Houses

House Description

Character Limit	1500 characters
Notes	Clubhouse's "Clubs" feature has been retired and replaced by "Houses." The official "Creating Houses" article (reconfirmed via second-pass direct full-text read) recommends filling in a description but still does not publish a numeric character limit; the 1500-character figure (carried over from the old Club Description spec) remains unverified for Houses
