What is pz centre on door handles

Last updated: April 1, 2026

Quick Answer: PZ centre refers to the standardized distance from the top of a door handle to the center of the lock cylinder hole, typically 92mm in European door hardware standards. This measurement ensures proper alignment and compatibility of door locks and handles.

Key Facts

PZ centre distance is typically 92mm, the most common European standard measurement
It measures from the handle's reference point (usually its center) to the lock cylinder center
This standardization ensures door handles and lock cylinders from different manufacturers are compatible
The PZ centre measurement is part of the DIN (Deutsche Industrie-Norm) door hardware standards
Incorrect PZ centre measurements can result in misaligned handles or non-functional locks

Understanding PZ Centre

PZ centre refers to a critical measurement in European door hardware installation. Specifically, it indicates the distance from a designated reference point on the door handle to the center of the lock cylinder hole. The most common PZ centre measurement is 92mm, which has become the standard across much of Europe for residential and commercial door hardware.

Measurement Standards

The PZ centre measurement is part of the comprehensive DIN standards system that governs door hardware dimensions and specifications. When manufacturers design door handles, lock cylinders, and door frames according to PZ standards, all components are engineered to work together with precise alignment. This standardization eliminates compatibility issues and ensures proper functionality of the locking mechanism.

Installation and Compatibility

When installing or replacing door hardware, the PZ centre measurement is crucial. If the distance between the handle and lock cylinder doesn't match the PZ standard, the handle may not align properly with the lock mechanism, resulting in difficulty operating the door or a non-functional lock. Builders and installers rely on PZ centre measurements to ensure all components work seamlessly together and meet safety requirements.

Common PZ Centre Sizes

While 92mm is the most common PZ centre distance, European standards also include other measurements such as 85mm for some applications. Door frames are drilled or routed specifically for these standard measurements, making it essential to verify the PZ centre distance when selecting replacement hardware or installing new doors.
