Free Mouse Spin Test - 360° Spin Counter & Rotation Tracker

Mouse Spin Test

Hold and drag your mouse in circles around the pad. Every 360° counts as one spin. 30-second timer, peak spins-per-second tracker, direction indicator.

Press Start. Place the cursor on the pad, hold the left button, and spin the mouse in circles around the center dot. Every full 360-degree sweep counts as one spin. Release at any point to pause.

Duration

Hold the left button and spin around the center dot.

Tip: higher DPI lets you spin faster with less hand motion. For fun comparisons, try both clockwise and counter-clockwise, and try slow deliberate circles vs fast wrist flicks.

Mouse Spin Test guide

How to use the Mouse Spin Test accurately

A mouse spin test asks one question: how many full 360-degree rotations can you make with your mouse in a fixed amount of time? Each rotation is measured as a complete angular sweep around a reference point — in this tool, the center of the tracking pad. Every full turn is one "spin.

01 What Is A Mouse Spin Test? A mouse spin test asks one question: how many full 360-degree rotations can you make with your mouse in a fixed amount of time?

02 How The Test Works The tool treats the pad's center as the origin. When you hold the mouse button down and drag, each pointermove event computes the angle from the center to your current cursor position using Math.atan2.

03 Peak Spins-Per-Second (SPS) Spins-per-second is computed over a rolling 1-second window. The tool tracks every angular delta with its timestamp, sums the last 1000 ms of absolute degrees, and divides by 360.

04 Spin-Out And Sensor Speed If your mouse sensor has a "max tracking speed" (IPS) lower than your physical speed, the sensor momentarily stops reporting motion — this is the spin-out bug.

Spins-per-second is computed over a rolling 1-second window. The tool tracks every angular delta with its timestamp, sums the last 1000 ms of absolute degrees, and divides by 360. Peak SPS is the maximum that number ever reached during your run.

Mouse Spin Test FAQ

Common mouse spin test questions

How does the mouse spin test count rotations?

It treats the pad center as an origin, computes the angle from center to your cursor on every pointer event, and sums the angular deltas (wrapped into ±180 degrees). Every 360 degrees of accumulated rotation equals one full spin.

What is a good spin count?

Over a 30-second round: under 10 is casual, 10-20 is average, 20-40 is fast, and 40 or more is very fast (usually high-DPI fingertip grip).

Why did my spin count plateau?

Most likely you exceeded your mouse sensor maximum tracking speed (IPS). Cheap optical sensors stop reporting motion past 50-100 IPS, which caps your spin rate.

Clockwise or counter-clockwise matters?

Only for the label on screen. Both directions count the same toward the total spin tally.
