Calibration workflow
PS Controller Calibration
Release the sticks and this PS controller calibration workflow will estimate center offset, deadzone needs, range behavior, and optional HID support.
Controller Calibration Wizard
Center offsets, range checks, and optional HID permission are grouped into one workflow.
No Controller Detected
Connect via USB or Bluetooth, then press any controller button to activate detection.
1. Center
Release both sticks and compare idle magnitude.
0.000
2. Deadzone
Use the larger suggested value as a starting point.
0.05
3. Permission
Calibration guidance uses Gamepad API values. WebHID permission is optional.

What Browser Calibration Guidance Can Do
PS controller calibration in a browser is guidance, not a firmware rewrite. The page reads live Gamepad API values, estimates center offset, suggests a practical deadzone, and groups follow-up checks into a simple workflow. It cannot permanently recalibrate the controller hardware, but it can show whether a PlayStation-style pad is returning to center consistently.
The calibration view is useful after a drift complaint, a repair, a firmware update, or a connection change. By combining stick scopes with numeric offsets, the PS controller calibration page helps you decide whether a game deadzone is enough or whether you should use manufacturer tools, console settings, cleaning, or hardware service.
Optional WebHID permission is handled as an explicit user action. Some compatible controllers may expose additional reports through HID, but the core controller calibration remains available without that permission. The page explains the state so users are not surprised by a prompt.
Center, Deadzone, And Range
Start with center. Place the controller on a desk and release both sticks. The gamepad calibration panel compares left and right stick magnitudes and highlights the larger idle value. If the offset is small and stable, a minor game deadzone may be enough. If the offset is large, a dedicated stick drift test should confirm the symptom.
Deadzone suggestions are intentionally conservative. A higher deadzone can hide drift, but it also removes fine movement. The PS controller calibration workflow presents a number that is easy to test in games rather than pretending one value fits every title. Competitive aim, racing steering, and camera control each tolerate deadzone differently.
Range checks come next. Move each stick around the edge and compare the trace on the circularity test if travel looks uneven. Calibration is not only about center. A controller can center well while failing to reach one edge, which can make diagonals, camera pans, or sprint activation feel inconsistent.
When To Use Other Tools
Use the PS controller calibration page when you need a structured decision. Use the stick drift test when the only question is idle movement. Use the circularity test when the outer range feels uneven. Use the PS5 controller test when you also need face buttons, triggers, and haptic fallback status.
If calibration values change after reconnecting the controller, compare USB and Bluetooth. If values are stable in the browser but wrong in one game, the game profile or deadzone settings are likely. If values are poor everywhere, firmware utilities or physical service may be needed.
The page is written for PlayStation-style controllers, but the same browser limits apply to all pads. It cannot update firmware, store calibration tables, or override the operating system. It can provide repeatable evidence before you change settings or contact support.
Diagnostic Glossary
Center offset
The distance between resting stick position and the expected zero point.
Calibration table
Device-level data used by firmware or drivers, not something this browser page writes.
Range check
A sweep to confirm that the stick reaches expected edges in every direction.
Questions Users Ask
Short answers for common diagnostic decisions on this page.
Can this permanently calibrate a PS controller?
No. It reads values and suggests actions. Permanent calibration requires supported manufacturer, console, or firmware tools.
Why is WebHID optional?
The basic Gamepad API is enough for center guidance. HID is broader and should only be requested after a clear user click.
What should I do after a high offset?
Confirm it with the stick drift test, compare connection modes, then adjust deadzone or use official repair and calibration options.
Useful Next Checks
Run a stick drift test
Check idle offset and deadzone before changing in-game sensitivity.
Measure circularity error
Trace the stick gate to find uneven travel or square clipping.
Check gyro support
Review motion capability, optional WebHID permission, and fallback tilt behavior.
