Run a free speed test right now. Test your internet speed in under 30 seconds — no signup, no software. Works on any browser, any device.
Need to run a speed test? Whether you want to test your internet, check if you're getting the speeds you pay for, or troubleshoot a slow connection, you can run a free speed test directly in your browser right now.
How to run a speed test
Running a speed test is fast and simple:
- Open SpeedCheckTest in your browser
- Connect to the network you want to test
- Press GO — the test starts automatically
- Wait 10–30 seconds for your results
Your results show three metrics: ping (ms), download (Mbps), and upload (Mbps). That's everything you need to know about your internet speed.
Tip: For the most accurate speed test, close other apps, use Ethernet instead of WiFi, and run the test when few people are using your network.
What does a speed test measure?
A speed test measures three things:
- Ping (latency) — Milliseconds it takes for data to travel to a server and back. Lower is better. Under 20 ms is great for gaming. Under 50 ms is fine for video calls.
- Download speed — How fast your connection receives data in Mbps. This determines how quickly websites load, videos stream, and files download.
- Upload speed — How fast your connection sends data in Mbps. This matters for video calls, cloud backups, and uploading files.
How fast should my speed be?
Your expected speed depends on your internet plan. Here's a general guide:
| Plan speed | Good result range | Suitable for |
|---|---|---|
| 25 Mbps | 20–23 Mbps | Single user, web + email |
| 50 Mbps | 40–48 Mbps | 2–3 users, HD streaming |
| 100 Mbps | 80–95 Mbps | Family use, 4K streaming |
| 200 Mbps | 150–190 Mbps | Heavy streaming, gaming |
| 500 Mbps | 400–475 Mbps | Large household, work from home |
| 1,000 Mbps | 700–950 Mbps | Power users, multiple 4K streams |
A good result is typically 70–90% of your plan speed. If you're getting less than 50%, something is wrong.
How to test my internet right now
To run a speed test and get an accurate reading, follow these steps:
- Close bandwidth-heavy apps (streaming services, downloads, large uploads)
- Connect via Ethernet cable if possible — WiFi always reduces speed
- Make sure no one else on your network is streaming or downloading
- Open SpeedCheckTest and press GO
- Run the test 2–3 times at different times of day for a baseline
What affects speed test results?
Several things can cause your speed test to show lower speeds than your plan:
- WiFi signal loss — WiFi adds 20–50% overhead. Use Ethernet for true speed.
- Network congestion — Your ISP's network gets busy during peak hours (evenings, weekends), slowing everyone down.
- Old router — A router older than 5 years may not support your plan's speeds. WiFi 5 on a gigabit plan is a bottleneck.
- Distance to server — Speed tests connect to a server. The farther away, the lower the measured speed.
- Too many devices — Every connected device shares your bandwidth.
- VPN — A VPN adds an extra routing step, reducing speed by 10–30%.
When should I run a speed test?
Run a speed test when:
- Your connection feels slower than usual
- Websites take too long to load or buffer during video
- You upgraded your internet plan and want to verify the new speed
- You changed your router or network setup
- You're troubleshooting with your ISP and need data to reference
- You work from home and want to verify connection quality
- You want to compare your speed to your ISP's advertised speeds
How does the speed test work?
Our speed test works in your browser using JavaScript. It opens multiple parallel connections to a nearby server and measures how fast data travels through each connection. The download test measures how much data arrives over 10 seconds. The upload test reverses the direction. The ping test sends a small packet and measures the round-trip time.
Using multiple streams simulates real-world conditions better than a single connection — just like streaming video opens multiple connections to deliver smooth playback.
Speed test FAQs
Can I run a speed test online for free?
Yes. SpeedCheckTest is completely free and runs directly in your browser. No software to install, no account to create, no payment details needed. Open the page and press GO.
How long does a speed test take?
A typical speed test takes 10–30 seconds total. The ping test is instant. The download test runs for about 10 seconds. The upload test runs for about 6 seconds.
Should I run a speed test over WiFi or Ethernet?
Ethernet gives more accurate results. WiFi adds signal loss and interference that reduces your measured speed. Run the test on WiFi if that's how you normally use the internet, but use Ethernet if you want to know your true connection speed.
How often should I run a speed test?
Run a speed test when you notice performance issues or when something changes in your setup (new router, new plan, network problems). If your speeds are consistent and good, once a month is enough to spot trends.
Why are my speed test results different each time?
This is normal. Your internet speed varies based on network congestion, time of day, server load, and WiFi conditions. Run tests at different times and compare the averages rather than individual results.
Key takeaways
To run a speed test, open SpeedCheckTest in your browser and press GO. Results appear in under 30 seconds: ping, download, and upload speeds. A good result is 70–90% of your plan speed. Run tests on Ethernet for accuracy and at different times to establish a baseline. If you're consistently below 50% of your plan, check your network setup or contact your ISP.
