Capacitive Touch Cover-Glass Thickness Calculator
Capacitive (PCAP/CTP) touch controllers struggle as cover-glass thickness grows. This tool estimates the maximum cover-glass thickness your touch layer can reliably sense, and flags when you need a bridge-ITO or metal-mesh solution.

FAQ
Why does thickness limit touch?
Mutual-capacitance coupling between the finger and the sensor decays with distance. Standard ITO sensors reliably sense through ~1.0 mm glass; beyond that signal-to-noise drops and false touches rise.
Can I use a thick cover with gloves?
Glove and wet-finger operation needs lower coupling thresholds and often a metal-mesh or DITO sensor, plus firmware tuning. Plan for ≤0.7 mm effective sensing for gloved use.
Need a touch stack-up that survives your environment?
