What is an Internet Speed Test?
An internet speed test measures how fast data travels between your device and the internet. It helps you understand whether your connection is performing as expected and suitable for your online activities.
Download Speed
Upload Speed
Ping (Latency)
Jitter
Who Should Use This Tool?
This speed test is useful for anyone who wants to:
- Verify if their internet plan delivers promised speeds
- Troubleshoot slow connection issues
- Check if their connection supports streaming, gaming, or video calls
- Compare speeds across different times of day
- Test speed before and after router or ISP changes

How to Use the Speed Test
Testing your internet speed takes just a few seconds. Follow these simple steps to get accurate results.
Prepare Your Connection
Before starting the test, optimize your setup for accurate measurements:
- Close bandwidth-heavy applications (streaming, downloads, cloud sync)
- Pause any ongoing downloads or updates
- If possible, connect directly to your router via ethernet cable
- Make sure other devices on your network aren't using heavy bandwidth
Start the Test
Click the GO button (play icon) to begin. The test runs through three phases:
- Ping Test - Measures connection latency and jitter (a few seconds)
- Download Test - Measures how fast you receive data (several seconds)
- Upload Test - Estimates how fast you can send data (several seconds)
Watch the speedometer needle move in real-time as the test progresses. The arrow icon below the speed display indicates whether download ↓ blue or upload ↑ purple is being tested.
Review Your Results
After the test completes, you'll see:
- Speed Values - Download, upload, ping, and jitter measurements
- Quality Rating - Overall connection quality (Excellent, Good, Fair, Poor)
- Recommended Uses - Activities your connection can handle (4K streaming, gaming, etc.)
- Server Info - The Cloudflare server location used for testing

Real-Time Speed Monitoring
Watch your connection speed update live during the test. The analog speedometer displays current speed with a smooth needle animation, making it easy to see speed fluctuations as data transfers.
Comprehensive Speed Metrics
Get a complete picture of your connection with four essential measurements:
- Download Speed - Measured in Mbps
- Upload Speed - Estimated based on download
- Ping (Latency) - Measured in milliseconds
- Jitter - Variation in ping times
Connection Quality Rating
After each test, receive an overall quality rating:
- Excellent - 4K streaming, competitive gaming
- Good - HD streaming, video calls
- Fair - Standard browsing, SD streaming
- Poor - May experience buffering, lag
Flexible Speed Units
Switch between two common speed measurement formats:
- Mbps - Standard unit used by ISPs
- MBps - Useful for file download times
Test History and Trends
Track your connection performance over time:
- View previous test results with timestamps
- See speed trends in the mini chart
- Compare results across different times
- History stored locally on your device
Global Server Network
Tests run through Cloudflare's worldwide server network, ensuring:
- Reliable and consistent measurements
- Low-latency connections to nearby servers
- Server location displayed after each test
Frequently Asked Questions
What is a good internet speed?
It depends on your usage. Here's a breakdown by activity:
Ping recommendations: Under 50ms is good for gaming, under 20ms is excellent.
Why is my speed lower than what I pay for?
Several factors can affect your measured speed:
- WiFi interference or distance from router
- Network congestion during peak hours
- Other devices or applications using bandwidth
- Router or modem limitations
- ISP throttling or network conditions
What's the difference between Mbps and MBps?
Megabits per second
- How ISPs advertise speeds
- Standard measurement unit
- Example: 100 Mbps connection
Megabytes per second
- Actual file download rates
- 8 bits = 1 byte
- Example: 12.5 MBps actual speed
Quick calculation: A 1GB file takes about 80 seconds to download at 100 Mbps (12.5 MBps).
What is ping and why does it matter?
Ping (latency) measures how long data takes to travel to a server and back, in milliseconds. Low ping is essential for:
Online Gaming
Video Calls
VoIP Calls
What is jitter?
Jitter measures the variation in ping times. High jitter causes choppy video calls, voice distortion, and gameplay stuttering even if your average ping is low.
Why does my upload speed seem estimated?
How often should I test my speed?
Test when you notice connection issues or want to verify performance. For tracking trends, test at the same time each day. Run multiple tests and average the results for the most accurate picture of your connection quality.
- Test during connection issues
- Same time daily for trend tracking
- Run 3-5 tests and average results
- Compare different times of day
Why do results vary between tests?
Speed fluctuations are normal due to:
- Network traffic variations
- Server load at test time
- Background processes on your device
- Wireless signal strength changes
