FaceRuler

FaceRuler is a free, browser-based facial attractiveness measurement tool that turns a single front-facing photo into an objective, numeric readout. Its Website Positioning is that of a transparent 'face rating instrument' rather than an entertainment quiz: instead of hiding its formula behind a black box, FaceRuler publishes every metric, target value and weight it uses, and cross-checks those targets against established facial anthropometry (Farkas) and attractiveness research such as the Rhodes 2006 meta-analysis. The Target Audience includes looksmaxxing and PSL-community members who want a stricter 0–8 community scale, ordinary users curious about 'how attractive am I', self-improvement and grooming enthusiasts tracking changes over 30/60/90-day retake cycles, and casual visitors who simply want an instant, no-signup answer. Core Features include a 478-point face-landmark engine that scores 8 metrics across 5 dimensions (symmetry, facial thirds/golden ratios, structure and FWHR, eye spacing and canthal tilt, and overall harmony), a dual output of a casual 1–10 attractiveness rating plus exact percentile and a stricter PSL tier (e.g. LTN, Chad, Stacy), a face shape detector, golden ratio and canthal tilt calculators, and a growing suite of companion tools. Content Features include an extensive guides library — the PSL Scale Guide, PSL Tiers, Looksmaxxing Dictionary, methodology and sources page, and a blog — all written to explain what each number means and to frame results as geometric measurements rather than judgments of personal worth, complete with mental-health resources. User Experience is deliberately frictionless: no account, no sign-up, upload-or-drag a JPG/PNG/WebP/HEIC file up to 30 MB or shoot directly with the camera, and get results in seconds with color-coded overlay lines (yellow facial thirds, blue canthal tilt, red FWHR box, green jaw width). Technical Features emphasize privacy and determinism — all free measuring runs on-device in the browser so the photo never leaves the user's machine, the engine is deterministic (identical landmarks always produce an identical score), and results are stored anonymously on the device for progress tracking. Monetization is a freemium model: the score, percentile, tier and five-dimension breakdown are free forever, while credit packs and a Pro subscription unlock deeper AI reports and unlimited measurements.
