About Us - Precision Online Ruler
Our mission is to deliver the most accurate, zero-cost 1:1 digital measurement tool across all devices.
🚀 Our Story and Vision
Penggaris Online HP CM (penggarisonline.com) was born out of a universal everyday challenge: needing to quickly measure a screw, card, ring diameter, or package dimension when no physical ruler is within reach. Simple image searches yield distorted rulers because screens vary wildly in Pixel Density (PPI).
We engineered an open, browser-native measurement platform that eliminates installation barriers. By pairing reactive SVG rendering with an ISO/IEC 7810 ID-1 card calibration mechanism (85.60 mm), we deliver exact 1:1 physical accuracy directly onto your smartphone glass.
