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.
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.

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? 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." The score is a fun benchmark for sensor tracking speed, grip style, and wrist mobility.

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. The difference between consecutive angles (wrapped to [-180, 180] to handle the discontinuity at ±180°) is accumulated. When the total absolute rotation exceeds 360°, you've completed one full spin. Sign indicates direction: positive = clockwise, negative = counter-clockwise.

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. Peak SPS is the maximum that number ever reached during your run. Most humans top out at 2-3 SPS with mouse acceleration off; competitive Kovaak spin-flickers can hit 4+.

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. Budget optical sensors stop at 50-100 IPS; flagship sensors like the PMW3389 or PAW3395 handle 400-650 IPS, which is effectively impossible to exceed by hand. If your spin count hits a plateau suddenly mid-round, your sensor is probably capping out. For the full diagnosis and repair path — spin-out vs drift vs jitter, the in-game confirmation routine, and every fix from mousepad to firmware — read the mouse spinning out guide. Not sure what your sensor is set to? Run the DPI analyzer to measure the DPI your mouse is actually reporting before you blame spin-out.

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.
