Ever printed a 3D model that came out the wrong size? Spent hours on a UI design that looked perfect on your screen but felt "off" on the actual device? The culprit is almost always incorrect on-screen measurements.
Most screen rulers are digital replicas of physical tools built for a world where every monitor had 96 DPI. Today, with 4K monitors, retina displays, and multi-screen setups, that assumption is catastrophically wrong. A 10 cm measurement on a laptop can appear as 7 cm on an external 4K monitor with a basic ruler—a 30% error that ruins precision work.
PixyScale fixes this at its core. It's not just another screen ruler; it's a calibration engine that bridges the digital and physical worlds with pixel-perfect accuracy.
Witness PixyScale match a physical ruler exactly—1 cm on screen equals 1 cm in reality.
This isn't a trick. It's automatic DPI calibration.
