Latency Test
Measure the delay between your device and the test server. Speedtest.now reports latency as ping, then adds jitter and packet loss so you can tell whether your connection is only slow or actually unstable.
Latency Results Explained
| Latency | Rating | What it feels like |
|---|---|---|
| Under 20 ms | Excellent | Ideal for competitive gaming, live calls, and remote desktop work. |
| 20–50 ms | Good | Responsive for most gaming, browsing, video calls, and streaming. |
| 50–100 ms | Usable | Fine for browsing and streaming, but fast games may feel delayed. |
| 100+ ms | Poor | Noticeable lag in games, calls, screen sharing, and remote control apps. |
What This Latency Test Measures
Ping
Round-trip time from your device to the server and back. Lower is better.
Jitter
How much your latency varies between samples. Stable latency matters for calls and gaming.
Packet Loss
The percentage of packets that fail to arrive. Even 1% can cause stutter and retries.
How to Improve High Latency
- Use Ethernet instead of Wi-Fi where possible.
- Choose the nearest game, VPN, or application server.
- Pause downloads, cloud backups, and streaming on other devices.
- Restart your router if latency suddenly spikes across every app.
- Test at different times of day to separate home network issues from ISP congestion.
