Speed Test
IdleHow SpeedTestHQ Measures Your Connection
SpeedTestHQ runs a short sequence of ping, download, and upload checks to estimate real-world performance. We select the nearest low-latency server from a curated network and measure throughput using parallel streams to reduce the effect of single-connection throttling.
We show four metrics that matter most for everyday use:
- Download: how fast you can receive data for streaming and browsing.
- Upload: how fast you can send data for video calls and backups.
- Ping: response time to a server, critical for gaming and calls.
- Jitter: consistency of ping, which affects real-time stability.

Frequently Asked Questions
How do I test my internet speed?
Simply click the "Start Speed Test" button on SpeedTestHQ. Our tool will automatically connect to the nearest server and measure your download speed, upload speed, ping, and jitter in seconds.
What is a good download speed?
A good download speed depends on your usage. For basic browsing and email, 10-25 Mbps is sufficient. For streaming 4K video, at least 25 Mbps is recommended. For online gaming, video conferencing, and multiple devices, 100 Mbps or higher is ideal.
What is the difference between Ping and Jitter?
Ping (Latency) measures the reaction time of your connection—how fast you get a response after you've sent out a request. Jitter measures the variability of the ping over time. Lower values are better for both, especially for real-time activities like gaming and video calls.
Why is my internet slow?
Slow internet can be caused by many factors, including network congestion, poor Wi-Fi signal, outdated router hardware, background downloads, or issues with your Internet Service Provider (ISP). Try restarting your router or moving closer to it to see if speeds improve.
