Mouse Speed & Acceleration Test

Free Mouse Speed & Acceleration Test Online

Want to know how fast your mouse really moves? This free online tool measures your cursor’s speed and acceleration in real time. Press Start, move your mouse across the test area, and watch the numbers update as you go.

You get live readings, a path trail of your movement, and a graph that shows how your speed changes over time.

What Is the Mouse Speed & Acceleration Test?

This tool tracks how quickly your mouse pointer moves across the screen. It measures speed in pixels per second (px/s) and acceleration in pixels per second squared (px/s²).

Speed tells you how fast the cursor is moving at a given moment. Acceleration tells you how quickly that speed is rising or falling. A positive value means you are speeding up. A negative value means you are slowing down.

What the Tool Shows You

The tool displays six readings while the test runs:

• Current speed: How fast your cursor is moving right now.
• Peak speed: The highest speed recorded during the test.
• Average speed: Your average speed across the whole test.
• Acceleration: How quickly your speed is changing at this moment.
• Peak acceleration: The highest acceleration recorded.
• Distance: The total distance your cursor has travelled, in pixels.

The tool also shows a timer, a status indicator (Ready or Test running), and a Speed over time graph. The graph also displays your peak speed value in its corner.

How to Use the Mouse Speed Test

1. Click Start test. The status changes to “Test running” and the timer begins.
2. Move your mouse inside the dotted test area. Your path appears as a trail.
3. Watch the six readings and the speed graph update as you move.
4. Click Stop test when you are done. The button changes to Stop while the test is running.
5. Click Reset to clear all results and start fresh.

How to Read Your Results

Use the numbers together rather than on their own.

Peak speed vs. average speed. A high peak with a low average means you made a few quick flicks but moved slowly the rest of the time. When the two are close, your movement was steady.

Acceleration values. Large positive and negative numbers are normal. Mouse movement involves quick starts and stops, so acceleration jumps up and down often. Peak acceleration captures your sharpest burst of speed change.

The speed graph. A smooth line points to steady movement. A jagged line shows frequent bursts and stops. You can use the graph to spot when in the test you moved fastest.

Distance. This shows how much total cursor travel your movement covered, which is useful for comparing tests of the same length.

Practical Uses

• Compare mouse settings. Run the same movement before and after changing your pointer speed settings, then compare the results.
• Compare different mice. Test each mouse the same way and see how the readings differ.
• Check consistency. Repeat the test a few times to see how steady your movements are.
• Understand your own movement. Gamers, designers, and anyone curious about their cursor control can see how fast and how smoothly they move.

Tips for Better Comparisons

• Use the same movement pattern each time, such as a repeated circle or side-to-side sweep.
• Keep the test duration similar, since distance and average speed depend on how long you run it.
• Change only one setting at a time so you know what caused any difference.
• Run the test more than once and compare the overall pattern instead of relying on a single result.

Why Your Results May Differ

The tool itself notes that speed is measured in pixels per second and that results vary with your screen, mouse DPI, and pointer settings. In practice, this means:

• A higher-resolution or larger screen may give different pixel values for the same hand movement.
• A mouse with a different DPI setting may produce different readings.
• Your operating system’s pointer speed settings affect how far the cursor travels for a given movement.

Because of this, compare your results against your own earlier tests rather than against numbers from other people’s devices.

Frequently Asked Questions

What unit does the tool use to measure speed?

Speed is measured in pixels per second (px/s). Acceleration is measured in pixels per second squared (px/s²).

Why is my acceleration sometimes negative?

A negative acceleration means your cursor is slowing down. This happens whenever you decelerate or stop a movement.

Does the tool measure my mouse DPI?

No. The tool measures how your cursor moves on screen. DPI and pointer settings affect those results, but the tool does not report DPI directly.

Can I compare my numbers with someone else’s?

Not reliably. Screen size, mouse DPI, and pointer settings all change the readings. Comparing your own tests on the same setup is more meaningful.

What does the Reset button do?

It clears the current readings and graph so you can begin a new test.

Why does the trail disappear gradually as I move?

The path in the test area is drawn as a trail that follows your cursor. It is a visual guide to your movement, while the numbers and the graph carry the actual measurements.
