What's your refresh rate?
We measure how many frames your display draws each second — 60, 120, 144 or 240 Hz — and show the motion so you can feel it.
Hold tight for a second while we count frames. The dot above moves in sync with your screen.
How the refresh rate test works
Your browser redraws the page once per display refresh, and it tells us the exact time of
every one of those frames via requestAnimationFrame. We collect the gaps
between recent frames, take the median (so one stutter can't skew the answer), and turn
it into a Hz figure — a 6.9 ms gap means 144 refreshes a second. The reading settles
after about a second of counting and keeps updating live.
The bouncing dot moves in sync with your display so you can see what the number feels like: at 60 Hz it hops in visible steps, at 120 Hz or more it glides. There's nothing to allow and nothing sent anywhere — the test starts on its own and only ever counts frames.
What the readings mean
- ~60 Hz — the standard refresh rate. Perfectly fine for work and video.
- 90–120 Hz — noticeably smoother scrolling and motion; common on newer phones and laptops.
- 144 Hz class — great for gaming; most popular high-refresh monitor tier.
- 200+ Hz — 240 Hz-class, esports-grade territory.
- Well below 60 — usually throttling: an unfocused tab, battery saver, or a busy machine.
Refresh rate test FAQ
My monitor is 144 Hz but the test says 60 — why?
Your browser can only draw as fast as the operating system refreshes the screen, and many systems ship with high-refresh monitors set to 60 Hz. Open your display settings, set the monitor to its highest refresh rate, and re-run the test.
Does this test work on phones and tablets?
Yes — it measures whatever your device's screen is actually doing, including 90 Hz and 120 Hz phone displays. Note that battery-saver and low-power modes often cap the refresh rate, so the reading can be lower than the panel's maximum on purpose.
Why does the number wobble or read low sometimes?
The measurement comes from frame timing, so anything that makes the browser skip frames — a busy CPU, other tabs, dragging the window, or the tab losing focus — drags it down. We use the median of recent frames to resist stutter; keep this tab focused and idle for the truest reading.
What refresh rate do I actually need?
60 Hz is the standard and fine for everyday work and video. 120–144 Hz feels noticeably smoother, especially for gaming and fast scrolling. 240 Hz is esports territory — great if you can feed it enough frames, overkill otherwise.
Is this the same as my FPS in games?
No. This measures how often your display refreshes — the ceiling. A game's FPS is how many frames your machine can produce, which can sit far below that ceiling. Nothing is captured or uploaded here; the test just counts frame callbacks in your browser.
