Click Speed Test: Measure Your Mouse CPS Online
Use this free click speed test to measure how many times your mouse buttons register during a timed attempt. The result is shown as clicks per second (CPS). Choose a duration from 1 to 60 seconds, test your left or right mouse button, or count both buttons together.
After each attempt, MouseDiag shows your total clicks, average CPS, current CPS, peak 1-second CPS, median CPS and a consistency estimate. You can also review a per-second chart, compare your personal best for the same test settings, view recent attempts, share a result or export your saved history as a CSV file.
A click speed test counts the mouse click events received by the browser during a selected time. CPS is calculated by dividing the accepted clicks by the test duration. For example, 30 clicks in 5 seconds equals an average of 6 CPS.
How to Use the Online Click Speed Test
- Choose a duration: Select 1, 2, 5, 10, 15, 30 or 60 seconds.
- Select a button mode: Choose Left Only, Right Only or Left + Right.
- Start clicking: Move the pointer into the test area and press the selected mouse button. Your first valid click starts the timer and counts as the first click.
- Keep clicking: Continue clicking inside the test area until the countdown reaches zero.
- Review your result: Check your average CPS, peak CPS, median, consistency and total clicks.
- Compare attempts: Use the chart, personal best and recent history to review completed tests. Reset the test when you are ready for another attempt.
For a fair comparison, keep the same mouse, browser, button mode and test duration. This is a mouse-input test designed for a computer mouse; use a desktop or laptop with a physical mouse for the intended result.
How Is CPS Calculated?
CPS means clicks per second. It describes the number of accepted mouse clicks recorded per second during a timed test.
Average CPS = Total Accepted Clicks ÷ Test Duration in Seconds
- 20 clicks in 5 seconds = 4 CPS
- 30 clicks in 5 seconds = 6 CPS
- 80 clicks in 10 seconds = 8 CPS
MouseDiag uses the selected test duration for the average CPS calculation. The first valid click starts the timer and is included in the total. Clicks received after the timer ends are not added to the completed attempt.
Current CPS
Current CPS shows your recent clicking rate using a rolling one-second window. During the first second, the calculation is adjusted to the elapsed part of that second. This number can rise or fall as your clicking rhythm changes.
Average CPS
Average CPS is the total accepted clicks divided by the full selected test duration. It is the main figure to use when comparing complete attempts with the same duration and button mode.
Peak 1-Second CPS
Peak 1-second CPS is the highest number of clicks recorded in any rolling one-second window during the attempt. It represents your fastest short burst, not your average speed across the whole test.
Median CPS and Consistency
Median CPS is the middle value among the test’s per-second clicking rates. Consistency estimates how similar those interval rates were. A higher consistency percentage means your pace varied less between measured intervals. It is a descriptive statistic, not a score for accuracy, gaming skill or mouse quality. A consistency value may not be available for very short tests because there are not enough intervals to compare.
Choose a Click Speed Test Duration
Short tests show brief clicking bursts, while longer tests show how well you maintain a pace. Choose the same duration whenever you want to compare your results fairly.
| Test duration | Useful for |
|---|---|
| 1–2 seconds | Very short bursts; results can change noticeably with one click. |
| 5 seconds | A quick, repeatable starting point for CPS comparisons. |
| 10–15 seconds | Comparing a longer clicking rhythm rather than only a short burst. |
| 30–60 seconds | Observing sustained clicking pace and changes over a longer attempt. |
There is no single best duration for every purpose. Use 5 seconds for a quick baseline, then try 10 seconds or longer if you want to see how your pace holds up. Do not compare the average CPS from different durations as if they were identical tests.
Left Click Speed Test
Select Left Only to measure repeated input from your mouse’s primary button. Only accepted left-button clicks contribute to the total and CPS result. This mode is useful when you want to compare your normal left-click speed across repeated attempts.
Right Click Speed Test
Select Right Only to measure repeated input from your mouse’s secondary button. The browser context menu is suppressed inside the testing area so that right-click events can be captured by the test. Use the same duration when comparing right-click CPS with a previous right-button attempt.
If you want to check whether the right button registers correctly rather than measure how quickly you can click it, use the Right Click Test.
Left + Right Combined Click Test
Select Left + Right to count accepted left- and right-button clicks in the same attempt. Both button types contribute to the total click count, while the separate counters show how many accepted clicks came from each button.
Combined mode measures the total browser-detected button events. It does not measure aim, reaction time, physical switch speed or whether a particular game will accept every input.
Review Your CPS Results, Chart and History
The tool provides more than a final CPS number. Use the additional results to understand how your clicking pace changed during an attempt and to compare tests made with matching settings.
- Clicking pace chart: Shows how many accepted clicks were recorded in each one-second interval.
- Personal best: Displays your highest average CPS among saved attempts with the same duration and button mode.
- Recent test history: Lists up to 10 recent attempts, including date, duration, mode, total clicks, average CPS and peak CPS. The browser stores up to 100 completed attempts.
- Achievements: Tracks personal milestones such as completing a first attempt or reaching a CPS or consistency target. These are practice milestones, not official rankings.
- Share result: Uses your browser’s share option when available, or copies the result text when clipboard access is supported.
- Export history CSV: Downloads your saved attempts in a spreadsheet-friendly CSV file.
Your completed results are saved in local browser storage on the device you used for the test. They are not uploaded to a MouseDiag account. Changing browsers, clearing site data or using another device may mean your previous history is unavailable. Use Clear History if you want to remove the saved attempts from that browser.
Click Speed Test for Gaming
A gaming click speed test can help you compare repeated mouse clicking before or after changing your technique or mouse. CPS is one measurement of clicking frequency, but it does not measure overall gaming performance.
In games, aim, timing, movement, accuracy, game mechanics and server-side input handling can matter as much as or more than raw CPS. A browser result is a useful personal comparison, not a guarantee that a game will register the same number of actions. If you are testing a particular clicking technique, compare repeat attempts under the same conditions and check the rules of the game or server you use.
How Accurate Is an Online CPS Test?
This click speed test measures mouse click events that reach the webpage while the test is active. It is useful for comparing your own attempts under similar conditions, but it is not a laboratory measurement of the mouse switch, hardware polling rate or complete input latency.
Results may vary with the mouse, operating system, browser, system workload, clicking technique and event timing. The chart and CPS values describe the events received by this browser test; they do not certify the physical condition or performance of your mouse.
For more consistent comparisons:
- Use the same physical mouse and computer.
- Keep the browser and test duration the same.
- Choose the same button mode for each comparison.
- Close unusually demanding background tasks if the computer is under heavy load.
- Repeat the test and compare average CPS, not only the highest short burst.
How to Improve Your Clicking Consistency
- Use a relaxed grip: Avoid unnecessary hand and finger tension.
- Keep a repeatable rhythm: A controlled pace makes attempts easier to compare.
- Practice with one duration: Compare like-for-like tests before changing the duration.
- Review the chart: Look for intervals where your pace slows or varies instead of focusing only on the peak.
- Take breaks: Stop if your hand or wrist feels uncomfortable. Do not force a faster pace through pain.
- Check button detection separately: If clicks seem to be missed, confirm that the mouse button registers normally before interpreting the CPS result.
Why Does My CPS Change Between Attempts?
Small differences between attempts are normal. Your starting rhythm, finger movement, fatigue, timing and the length of the test can all affect the result. A short test is especially sensitive to a small number of clicks, while a longer test gives more time for your pace to change.
Compare average CPS for the same duration and mode. Use peak 1-second CPS to review your fastest burst, and use the chart and consistency estimate to understand whether your pace stayed steady.
Click Speed Test Troubleshooting
The click counter does not increase
Move the pointer into the testing area and use the mouse button selected in the mode control. The first valid click starts the timer. If no clicks are detected, check the mouse in another application and try the test in a different browser.
Right clicks are not counted
Choose Right Only or Left + Right, then right-click inside the testing area. Right-clicks made outside the test area are not part of the attempt.
The test will not start with my selected button
Check the selected mode. Left Only starts with a left click, Right Only starts with a right click, and Left + Right accepts either button. The duration and mode controls are temporarily disabled while a test is running.
My mouse registers extra clicks
This page measures intentional repeated clicking speed; it is not designed to diagnose unwanted double-click behavior. If one physical press sometimes produces two click events, use the Double Click Test to investigate that separate issue.
Click Speed Test vs. Mouse Button Test
A click speed test measures how many accepted clicks occur during a selected period. A mouse button test checks whether the left, middle and right buttons are being detected. Use the Mouse Button Test if your goal is to check button detection rather than measure clicking speed.
