Double Click Test — Check Mouse Speed
A double click test measures how quickly you can double-click your mouse and detects whether your mouse is producing accidental double-clicks from a failing switch. There are two very different use cases: measuring intentional double-click speed (how fast you can deliberately click twice) and detecting unintentional double-clicks caused by switch bounce (where a single physical press registers as two events). The operating system defines a double-click as two clicks within a configurable time window — 500 milliseconds by default on Windows, and approximately 400 milliseconds on macOS. Clicks faster than this threshold are interpreted as a double-click and trigger actions like opening files, selecting words, or launching applications. Your physical double-click speed matters for productivity: power users who double-click rapidly to open files or select text benefit from a well-calibrated OS double-click speed setting. Gamers rarely use deliberate double-clicks, but accidental double-clicks from a worn switch cause missed shots and unintended actions in games. The critical distinction: an intentional double-click produces two counter increments from two physical presses; switch bounce produces two increments from one physical press. If you click once and see two counter increments, your left switch is bouncing — a hardware defect, not a speed issue. The Windows double-click speed can be adjusted in Control Panel → Mouse → Double-click speed, and macOS equivalent is in System Settings → Mouse → Double-Click Speed. This free test helps you calibrate both your mouse hardware and OS settings for your specific usage pattern.

Side buttons (Back/Forward) require a mouse with extra buttons. Not all mice support button 3 or 4 — if they don't light up, your mouse may not have those buttons.
What Is a Good Double-Click Speed in Milliseconds?
Use the table below to interpret your test results and understand what each outcome means for your mouse health.
| Click Interval | Status |
|---|---|
| < 100ms interval | Very Fast |
| 100–200ms interval | Fast |
| 200–350ms interval | Average |
| 350–500ms interval | Slow |
| > 500ms interval | Too Slow |
Windows default double-click threshold is ~500ms. macOS default is ~400ms. Adjust in mouse settings if you click faster or slower than these defaults.
Frequently Asked Questions
What is the double-click speed setting in Windows?
Windows defines a double-click as two clicks within the double-click time threshold, which you can adjust in Control Panel → Mouse → Buttons tab → Double-click speed slider. The default setting is roughly in the middle of the slider, corresponding to approximately 500 milliseconds. If you set it faster, the OS requires your two clicks to be closer together to register as a double-click. If you set it slower, clicks that are further apart still register as a double-click. If your OS is misidentifying single clicks as double-clicks, move the slider toward 'Slow' — if it is failing to detect intended double-clicks, move it toward 'Fast'.
Why does my mouse double-click when I single-click?
This is switch bounce — a hardware defect where the mechanical microswitch inside your mouse button registers two clicks from one physical press. The spring weakens over time and the metal contact bounces between open and closed states before settling. Moving the Windows double-click speed slider to 'Slow' can mask the issue by requiring clicks to be closer together to count as a double-click, reducing false double-clicks from switch bounce. However, this is a temporary workaround — the switch will continue to degrade. A permanent fix requires replacing the switch (Omron D2FC-F-K(50M) is a common replacement, costing about $1–3) or claiming a warranty replacement from your mouse manufacturer.
How do I test if my mouse is double-clicking from switch bounce?
Use this tool and click slowly — one deliberate single press at a time, waiting about one second between clicks. Watch the counter: each physical press should add exactly 1. If you see the counter jump by 2 from a single press, your switch is bouncing. For confirmation, try the same test in a text editor — type a single capital letter by pressing Shift and one key. If the letter types correctly with no repetition, the bounce is in the mouse button only. You can also use a tool like MouseTester.exe (Windows-only download app) to graph the timing of your clicks and visualize bounce events.
Does a double-click test apply to gaming mice?
Yes, and it is particularly important for gaming mice because they are used far more intensively than office mice, accelerating switch wear. Gaming mice are commonly the subject of warranty claims for double-clicking, especially from manufacturers like Logitech (G502, G102/203 series), Razer (DeathAdder series), and Corsair. The fix in gaming context is almost always switch replacement — optical switches (Razer TTC optical, SteelSeries optical) cannot double-click due to no moving contacts and are increasingly the standard for premium gaming mice specifically to avoid this issue.
What is the difference between double-click speed and CPS?
Double-click speed measures the interval between two consecutive clicks in milliseconds, relevant for OS-level double-click detection and file/folder interactions. CPS (clicks per second) measures how many clicks you can register per second over a test window, relevant for gaming click-rate benchmarking. A high CPS player can achieve 10+ clicks per second (100ms between clicks), well within the fastest double-click speed settings. The two metrics are related but serve different purposes: CPS is about sustained clicking speed, double-click speed is about the timing of two deliberate consecutive presses and how the OS interprets them.
Can double-click speed be adjusted on macOS?
Yes. On macOS, open System Settings → Mouse → Double-Click Speed slider. Moving the slider to the right increases the required speed (shorter interval between clicks must register as double-click). Moving it left allows slower double-clicks to register. The macOS default threshold is approximately 400 milliseconds — slightly faster than Windows default. If you are experiencing accidental double-clicks on macOS from switch bounce, moving the slider to the leftmost position (slowest) reduces false detections, though permanent hardware replacement remains the correct long-term fix.
