Hi Product Hunt community! 👋 I’m the maker behind onlineruler.online, and I’m incredibly excited to share it with you all today!Why did I build this?We’ve all been there: you need to quickly measure something on your desk a package, a notebook, or a phone screen—but your physical ruler is nowhere to be found (probably buried under a pile of papers). I wanted to build a zero-friction, always-available solution that just works.What makes it special?Instant Calibration: No complicated setup. It accurately calibrates to your screen size so your measurements are precise.Dual Units: Easily switch between inches and centimeters ($cm$).Clean & Ad-Free: A minimalist, distraction-free interface designed for pure utility.I’d love your feedback! This is just the beginning. I’d love to know:Did it accurately reflect your real-world measurements?What extra features would make this a daily bookmark for you? (e.g., an on-screen pixel ruler for designers, a protractor, etc.)Thank you so much for checking it out. I'll be here all day to answer your questions and chat! Best,Muhammad Shakeel
