PD Measure
Measure your pupillary distance in seconds — 100% private
Free online PD measurement tool. Measure your pupillary distance (PD) for glasses with a webcam, a photo, or a printable ruler — 100% private, no app.
Hey Product Hunt! 👋
I built PD Measure after noticing something frustrating: to order glasses online you need your pupillary distance, but most "free" PD tools are lead-capture funnels for glasses retailers — they make you sign up, push you toward a purchase, or quietly upload your selfie to their servers.
PD Measure is the opposite:
🔒 100% client-side — face-landmark detection runs in your browser (MediaPipe). Your photo never leaves your device. There's no server to upload to.
📷 Three ways to measure — guided webcam capture with a multi-frame confidence score, photo upload with a credit card for scale, or a printable true-to-scale ruler if you'd rather skip the camera entirely.
👓 Everything opticians ask for — total PD, monocular (dual) PD, and near PD for reading glasses, exportable as a PDF you can hand to any retailer.
🆓 No signup, no email, no upsell. It even works offline. The code is open source on GitHub.
It's genuinely free because measuring your PD shouldn't cost your data. I'd love your feedback — especially on measurement accuracy across different devices and lighting. Ask me anything!
