Four tests on one page — buttons, polling, double-click & CPS
Each card shows what to run in the tool above and what the readout tells you about your hardware — plus pointer tracking on the same page.
Buttons & scroll wheel
What it measures
Each switch should send one press; the wheel should report steady direction and tick size. Dead buttons, sticky middle clicks, or skippy scroll show up immediately — the dedicated scroll test adds up/down counters and ticks per second.
Double click test online
What it measures
Gaps under ~80 ms usually mean switch bounce (the mouse double-clicks by itself). Deliberate double-clicks land around 100–250 ms; Windows accepts up to ~500 ms.
Mouse polling test (Hz)
What it measures
Polling is how often the mouse reports position to the PC. A browser test estimates Hz from pointer timing; peak should match your OS and vendor setting when the link is healthy.
CPS click speed test
What it measures
CPS measures click speed in a timed window. A 5-second run filters lucky 1-second bursts — not to be confused with unrelated “CPS” acronyms elsewhere on the web.
How to test buttons, wheel, polling & double-click
Work top to bottom on this page: buttons and scroll wheel first, then polling and CPS, then double-click and tracking. Most faults show up in under three minutes.
-
Test buttons & scroll wheel
Click left, right, middle, back, and forward one at a time, then scroll up and down. Each button should highlight; ticks should rise smoothly both ways. Open the full scroll test for delta logs if the wheel feels uneven. See also: full scroll test .
Tip Test side buttons twice — intermittent faults hide on a single press
-
Run the mouse polling test
Click Start on the polling pad and move the mouse steadily. Note peak Hz — 1000 Hz gaming mice should read near 1000 when wired and focused. Then pick a CPS duration (5s is standard) and click the arena as fast as you can. See also: polling test pad .
Tip Use a direct USB port or nearby dongle for the steadiest Hz readout
-
Double click test & tracking
Double-click the test pad several times and read the interval log for chatter. Finish with slow circles and fast flicks on the tracking canvas — gaps in the trail can mean smoothing or wireless dropouts. See also: double click test pad .
Tip Screenshot the double click test log before a return or RMA
Mouse test checklist
Buttons & scroll wheel
Every primary click bumps its counter once per press. Scroll ticks rise evenly both directions — missing middle clicks often mean a worn wheel switch.
Double click test
No sub-80 ms chatter when you intended a single click. Deliberate double-clicks should log consistently between ~100–500 ms.
Mouse polling rate
Peak Hz should match your software setting (e.g. 1000 Hz). Large gaps in the bar graph can mean USB power saving or a weak wireless link.
CPS & tracking
CPS scores feel stable across repeated 5s runs. Tracking trails stay continuous during slow movement without long gaps.
When to run each mouse test
Dead or sticky buttons / wheel
- Press every button on the diagram once.
- Scroll up and down — watch direction, delta, and ticks.
- Reset counts and re-test any switch that felt soft.
Mouse double-clicks by itself
- Run the double click test pad on the faulty button.
- Look for random sub-80 ms intervals in the log.
- Screenshot results before buying a replacement or RMA.
Verify 1000 Hz polling
- Set 1000 Hz in mouse software, then run the polling test.
- Compare peak Hz on USB vs wireless.
- Re-test after moving the dongle closer.
CPS / gaming click speed
- Use the 5s CPS test as your standard benchmark.
- Compare wired vs wireless on the same technique.
- Track personal best across practice sessions.
Mouse troubleshooting guide
Mouse issues? Self-diagnose with the pads on this page — match your symptoms to the fix list below.
Double-click issue
Symptoms A single click opens files twice, or items release while dragging — classic switch bounce.
Solution
- Run the double click test pad and screenshot sub-80 ms chatter.
- Blow compressed air around the switch; avoid liquid unless you know the assembly.
- Raise double-click speed in Windows or macOS mouse settings as a temporary mask.
- Replace the switch or mouse if bounce persists in the interval log.
Cursor drift / jitter
Symptoms The cursor moves on its own or jitters when the mouse is still on the desk.
Solution
- Trace slow circles on the pointer tracking pad — gaps mean smoothing or dropouts.
- Clean the sensor lens and try a cloth mouse pad (avoid glass for testing).
- Disable pointer acceleration in OS settings while you test.
- Swap USB port or dongle if drift only happens wirelessly.
High latency
Symptoms The mouse feels laggy in games or the cursor trails behind fast flicks.
Solution
- Run the mouse polling test — peak Hz should match your software setting.
- Plug into a direct motherboard USB port (avoid unpowered hubs).
- Update mouse firmware and GPU drivers; disable USB selective suspend.
- Charge or replace batteries; turn off aggressive power saving on wireless.
Unstable connection
Symptoms Clicks or movement drop out intermittently — common on 2.4 GHz wireless.
Solution
- Move the receiver closer (USB extension or front-panel port).
- Keep routers, phones, and Bluetooth headsets farther from the dongle.
- Charge the battery and re-pair in vendor software.
- Compare wired vs wireless on the button diagram to confirm the link.
Scroll wheel skips or one-way scroll
Symptoms Pages jump unevenly, the wheel only scrolls one direction, or some notches register nothing.
Solution
- Run the mouse scroll test — compare up vs down tick counts and read the delta log for missing rows.
- Blow compressed air around the wheel encoder; avoid oil or water unless you know the assembly.
- Disable browser extensions that remap scroll; retest on a plain tab.
- If delta spikes wildly or one direction stays at zero, plan for encoder repair or replacement.

Mouse test online FAQs
What is a click test?
A click test checks whether mouse buttons register reliably and how fast you can click. On this page, use the CPS arena for timed click speed (1s, 5s, 10s), the double click test pad for switch chatter, and the button diagram for left, right, middle, back, and forward presses. For scroll-wheel clicks, open our scroll test or press-test middle click here.
How do I run a mouse speed test?
Mouse speed test usually means polling rate — how often the mouse reports position in Hz. Scroll to the polling pad on this page, click Start, and move steadily to read peak Hz (125, 500, or 1000). For a dedicated mouse speed and polling test with a full graph, open our mouse polling test page.
How do I test mouse polling rate online?
Open this page, scroll to the polling pad, click Start, and move the mouse steadily inside the pad. The Hz readout and bar graph estimate report rate from pointer event timing — expect roughly 125, 500, or 1000 Hz when your OS and mouse software match. Keep this tab focused for the steadiest mouse polling test result.
How do I test polling rate of a mouse?
Set your target Hz in mouse software or Windows first, then run the browser polling test here. Peak Hz should align with that setting. This is an estimate from move-event gaps, not a USB analyzer — but it reliably shows whether the browser is getting 125 vs 500 vs 1000 Hz reports.
How do I test mouse double click problems?
Click the double click test pad twice quickly, then repeat on left and right buttons. The interval log marks Chatter under ~80 ms (classic switch bounce), Double-click under ~500 ms, and Normal for slower gaps. Random sub-80 ms entries when you meant one click confirm a worn micro-switch.
How do I run a double click test on my mouse?
Use the double click test section on this page — no download. Click the pad as you would to open a file. Each press logs its gap from the previous one so you can compare deliberate double-clicks (~100–250 ms) against accidental bounce.
What is a mouse double click test online?
It is a browser tool that records the milliseconds between mouse clicks so you can spot switch chatter, test double-click speed, and diagnose a mouse that double-clicks by itself. This page includes that test alongside polling, CPS, buttons, and tracking.
How do I test clicks per second (CPS)?
Pick 1, 5, or 10 seconds in the CPS arena, click the pad as fast as you can until the timer ends, and read your clicks-per-second score. Timing uses high-resolution performance.now() timestamps. Most people score 5–7 CPS; 8–10 is fast. Your personal best saves on this device.
Which mouse buttons does this test?
Left, right, middle (wheel click), Back, and Forward via Pointer Events. Extra programmable buttons past Back/Forward usually never reach the page — check those in vendor software.
How do I test the scroll wheel?
Scroll over the button diagram area on this page — direction, delta, and tick count update live. For a full scroll test with per-tick log, delta graph, up/down counters, and ticks per second, open our dedicated mouse scroll test page.
How to test mouse scroll wheel online?
Use the scroll wheel section on this mouse test center for quick direction and delta checks, or open the mouse scroll test for a detailed event log, animated wheel diagram, and delta history graph — both run in the browser with no install.
Why doesn’t my side button register?
Only Back and Forward side buttons typically reach the browser. Other side keys need the mouse maker’s software. Also check OS remapping and that the page has focus.
Do I need to install anything?
No. The full mouse test — double click, polling rate, CPS, buttons, wheel, and tracking — runs in your browser with Pointer Events.
Tips for buttons, wheel & polling tests
-
Windows focus & remapping
Keep this tab focused. Check Settings → Bluetooth & devices → Mouse for button swaps or disabled navigation buttons before blaming the hardware.
-
macOS mouse settings
System Settings → Mouse. Confirm secondary click and scroll direction match what you expect while testing.
-
USB / wireless path
Prefer a direct motherboard USB port or a nearby wireless dongle. Bad hubs and low battery can drop clicks or scroll events.
-
Verify what you saw
Reset counts, re-press the suspect button, and compare left vs right. If only browser Back/Forward fail, check OS shortcuts before RMA.
