Gamepad Calibration Tester
Inspect your controller's axis ranges, centre values, and stick input directly in your browser. Leave the controller centred when connecting it, then use the live readings to check for unusual axis behaviour or centre offsets.
Live Gamepad Axes
Connect a controller to inspect its axes.
This is an inspection and calibration assistance tool. It cannot physically recalibrate a controller, change firmware, or modify operating system calibration settings.

Gamepad Axis Inspection & Calibration Assistance
This gamepad calibration tester helps you inspect controller axis behaviour directly in your browser. Connect your gamepad, keep the sticks centred, and view the live values reported by the browser.
The tool can help you identify unusual centre values, unexpected movement, or axis ranges that do not appear to reach the expected limits. It is designed as an inspection aid rather than a replacement for system level controller calibration.
How to Use the Gamepad Calibration Tester
For the most useful initial reading, leave your controller sticks centred before connecting it. Once the browser detects the gamepad, move each analog stick through its normal range and observe the reported axis values.
- Connect your controller to your computer.
- Leave the analog sticks centred.
- Wait for the browser to detect the gamepad.
- Check the live axis values.
- Move each stick slowly through its full range.
- Reset the observed ranges and repeat the test if needed.
What Does a Gamepad Axis Test Check?
A controller axis represents an input value reported by an analog control. For a typical gamepad, the analog sticks expose horizontal and vertical axis values that change as the stick moves.
Inspecting these values can help you understand how your controller is being reported to the browser and whether the stick appears to return consistently toward its centre position.
Centre Position
When an analog stick is released, it should normally return toward its centre position. A noticeable offset or continuous movement while the stick is untouched can be useful information when investigating possible stick problems.
Axis Range
Moving an analog stick toward its edges lets you observe the range of values reported by the controller. The exact values and behaviour can vary between controllers, operating systems, browsers, and input mappings.
Observed Minimum and Maximum
This tester can observe the minimum and maximum values encountered during the current test. Reset the observed ranges before starting a new measurement if you want to compare another movement cycle.
Gamepad Calibration vs Axis Inspection
It is important to distinguish between calibration inspection and actual controller calibration. This page can display the input values exposed by the connected gamepad, but it cannot physically recalibrate the controller.
The tool also cannot modify Windows, macOS, Linux, console, driver, firmware, or other operating system calibration settings. If your controller requires system level calibration, use the appropriate calibration or controller settings provided by your operating system or device manufacturer.
Why Check Controller Axis Values?
Axis inspection can be useful when a controller behaves differently from what you expect in a game or application. A browser based test provides a quick way to see whether the controller is producing live analog input before investigating software specific settings.
- Check whether the controller is detected.
- Inspect live analog stick values.
- Observe the stick centre position.
- Check the observed axis range.
- Look for unusual or unexpected movement.
- Compare stick behaviour before troubleshooting a game.
Gamepad Calibration Tester and Stick Problems
A calibration or axis inspection test can provide useful information when investigating possible stick issues. If an analog stick produces movement while it is released, this may indicate unwanted centre movement.
However, an axis reading alone does not establish the cause of a controller problem. Stick behaviour can be affected by the physical controller, input mapping, drivers, browser behaviour, or the game itself.
For a more focused investigation of unwanted stick movement and centre behaviour, use the site's dedicated stick drift and deadzone tester.
Controller Calibration in the Browser
Browser based testing is useful because it lets you inspect the controller input exposed to a web application without installing additional testing software.
The browser can report controller buttons and analog axes when the connected device and browser support the required gamepad functionality. The values shown by this tester therefore represent the input available to the web page rather than a direct measurement of every internal controller component.
What If the Axis Values Look Unusual?
If the reported values look unexpected, first reconnect the controller and repeat the test with the sticks released and centred. Then move the affected stick slowly through its complete range.
If the behaviour continues, compare the result in another supported browser and check whether the operating system recognises the controller correctly.
Keep in mind that different controllers can expose different input ranges and mappings. An unusual looking number does not necessarily mean that the controller is defective.
Frequently Asked Questions
What is a gamepad calibration tester?
A gamepad calibration tester is a browser based tool that helps inspect controller input, including analog stick axis values, centre positions, and observed ranges.
Can this tool calibrate my controller?
No. This tool provides calibration assistance and input inspection only. It cannot physically recalibrate a controller or change operating system calibration settings.
What are gamepad axes?
Gamepad axes are analog input values reported by controller controls such as analog sticks. Their values change as the stick moves.
Why should I centre the sticks before testing?
Starting with the sticks centred provides a useful reference for observing the controller's initial axis values and possible centre offsets.
Can this tester detect stick drift?
It can help you observe unwanted analog stick movement while the stick is released. For a dedicated drift and deadzone analysis, use the site's stick drift tester.
Why does my controller show different axis values?
Controller models, browsers, operating systems, drivers, and input mappings can expose controller data differently. Not every gamepad reports identical axis ranges.
Can I reset the observed axis range?
Yes. Use the Reset observed ranges button to clear the currently observed minimum and maximum values and begin a new observation.
Inspect Your Gamepad Axes Online
Use this gamepad axis tester to inspect live controller input directly in your browser. Connect your gamepad, keep the sticks centred, and then move them through their range to observe the values reported by the browser.
Connect → centre → detect → move → inspect.
