Primary Topic & Search Intent: xiaohongshu rednote cover size calculator — Mixed Intent (Interactive Calculation + Formula & Methodology Reference)
Accepted Input Parameters: Accepts 3 calibrated domain parameters: (1) Saves (Collects) + Likes [valid range: 10–50000 actions, default: 450 actions, step: 10], (2) Comments + Shares Count [valid range: 5–10000 actions, default: 120 actions, step: 5], and (3) Follower Count [valid range: 0.5–1000 k followers, default: 15 k followers, step: 0.5].
Computed Outputs & Processing Engine: Computes 3 real-time output metrics: Primary Metric RedNote CES Algorithm Score (CES points), Secondary Metric Projected Traffic Pool Tier (k impressions), and Tertiary Diagnostic Estimated Brand Post Rate (USD/post), plus a 5-tier (0.5x to 5.0x) sensitivity matrix. (deterministic Bilibili & 4K Video Suite mathematical engine (cost multiply model) with 0.5x–5.0x sensitivity matrix)
Data Privacy & Operational Scope: 100% Client-Side Browser Execution: files and parameters remain in local device memory. Calibrated specifically for Saves (Collects) + Likes values between 10 and 50000 actions and Comments + Shares Count between 5 and 10000 actions; extreme outlier values outside these bounds may exhibit non-linear variance.

Xiaohongshu & Douyin Creator Playbook: REDnote Growth Mechanics

Xiaohongshu (REDnote, Little Red Book): China 300M+ MAU lifestyle platform -- beauty, fashion, travel, food -- where search-driven discovery beats follower counts. The algorithm: interest graph + search intent; a new account first post can hit 10k views on keyword merit. Content grammar: aesthetic cover image (the click), 3-9 image carousels or 30-60s video, genuine review tone (the platform punishes advertorial feel), and keyword-rich titles (users search like Google: best sunscreen oily skin).

Douyin (Chinese TikTok, 700M+ DAU): pure interest-graph distribution, 1-3 minute sweet spot shifting longer, live commerce integration (the top earners sell live, not via ads). Cross-posting: content can flow Douyin to TikTok but not the reverse culturally -- aesthetics and meme grammars differ. Language: Mandarin dominates; English-niche creators exist but the algorithm favors Chinese-language engagement.

The foreign-creator reality: account verification needs Chinese ID or business license (workarounds exist via MCNs but add dependency); payment/monetization requires Chinese bank settlement; and content must navigate platform + regulatory sensitivities (fashion/beauty/travel are safe; politics/finance are minefields). The studio helps plan content for both platforms -- but the operational hurdles are real and should be faced before investing months.

The content-format specifics for RED: carousel posts (3-9 images) still outperform video for product/lifestyle content -- users save carousels at 3x the rate (the save is the conversion precursor). Video wins for tutorials and vlogs. The cover image decides 80% of click-through: text overlay with the benefit, bright aesthetic, human face. This is a visual-search platform wearing social clothes.

The search-keyword research method: Xiaohongshu search bar autocomplete is the keyword tool (type your topic, note the suggestions -- those are real user queries). Titles should mirror the exact phrasing users search: best sunscreen for oily skin beats my summer skincare routine by 10x in search traffic. This is SEO for a social platform, and most creators ignore it completely -- the arbitrage is wide open.
