XP-Pen X4 pen notes

Overview

The X4 pen series was introduced with the X4 Smart Chip Stylus pen that came with the XP-Pen Artist 12 GEN3 released in 2025.

Pressure range

XP-pen states:

  • IAF: 2gf

  • Max pressure: NOT STATED

My measurements:

  • I have not measured it yet. When I get 3 of them I will measure.

  • But subjectively, I would agree that IAF is close to what XP-Pen states, and the max pressure seemed to be in the GOOD range (>350gf).
