Test your internet connection speed instantly. Press the Start button below to measure your download speed, upload speed, and ping latency.
Powered by Fast.com (Netflix) — measures your real download speed.
An internet speed test measures three key metrics of your connection by sending and receiving data packets between your device and a test server. The entire process takes about 30 seconds and runs directly in your browser — no software installation needed.
Here's what happens during each phase:
| Metric | Good | Average | Poor | What It Affects |
|---|---|---|---|---|
| Download | 100+ Mbps | 25-100 Mbps | <25 Mbps | Streaming, browsing, downloads |
| Upload | 20+ Mbps | 5-20 Mbps | <5 Mbps | Video calls, cloud backups, streaming |
| Ping | <20ms | 20-50ms | >100ms | Gaming, video calls, responsiveness |
| Jitter | <5ms | 5-30ms | >30ms | Call quality, streaming stability |
The speed you need depends on how many people and devices share your connection, and what you do online. Here's a practical guide:
| Activity | Minimum Speed | Recommended | Devices |
|---|---|---|---|
| Email & web browsing | 3 Mbps | 10 Mbps | 1 |
| HD video streaming (Netflix, YouTube) | 5 Mbps | 25 Mbps | 1 |
| 4K Ultra HD streaming | 25 Mbps | 50 Mbps | 1 |
| Video conferencing (Zoom, Teams) | 3 Mbps up/down | 10 Mbps | 1 |
| Online gaming | 10 Mbps | 25 Mbps | 1 |
| Working from home | 25 Mbps | 100 Mbps | 2-3 |
| Family household (4+ devices) | 100 Mbps | 300 Mbps | 4-8 |
| Smart home + heavy streaming | 200 Mbps | 500+ Mbps | 10+ |
Pro Tip: Your ISP advertises "up to" speeds. Real-world performance is typically 70-90% of the advertised maximum. If you're getting less than 70%, contact your ISP or check for WiFi bottlenecks.
If your speed test shows numbers below what you're paying for, here are the most common causes:
WiFi is always slower than a wired connection. Walls, distance, and interference all reduce WiFi speeds. If your WiFi test shows 50 Mbps but Ethernet shows 200 Mbps, the problem is your wireless connection — not your ISP. Try changing your WiFi channel or extending your range.
If someone in your house is downloading a large file or streaming 4K video, your speed test will show lower results. Enable QoS on your router to prioritize your speed test or important activities.
Some ISPs slow down certain types of traffic during peak hours. Test at different times of day — if speeds are significantly lower in the evening (7-11 PM), congestion or throttling may be the cause.
An outdated router, old firmware, or overheating hardware can bottleneck your speeds. Try restarting your router and updating the firmware.
Older devices with WiFi 4 (802.11n) can't match the speeds of WiFi 5 or WiFi 6 routers. Your device's WiFi adapter is often the bottleneck, not your internet plan.
| Speed Tier | Download | Upload | Best For | Typical Cost |
|---|---|---|---|---|
| Basic | 25-50 Mbps | 3-5 Mbps | 1-2 people, light use | $30-40/mo |
| Standard | 100-200 Mbps | 10-20 Mbps | Small family, streaming | $50-65/mo |
| Fast | 300-500 Mbps | 20-50 Mbps | 4+ people, gaming, WFH | $65-80/mo |
| Gigabit | 1000 Mbps | 100-1000 Mbps | Power users, large households | $80-100/mo |
| Multi-Gig | 2000+ Mbps | 2000+ Mbps | Future-proof, content creators | $100-150/mo |

| Unit | Full Name | Used For | Conversion |
|---|---|---|---|
| Mbps | Megabits per second | ISP plans, speed tests | 1 Mbps = 0.125 MB/s |
| MBps (MB/s) | Megabytes per second | File downloads, disk speed | 1 MB/s = 8 Mbps |
| Gbps | Gigabits per second | Fiber plans, enterprise | 1 Gbps = 1,000 Mbps |
| Kbps | Kilobits per second | Legacy, very slow connections | 1 Mbps = 1,000 Kbps |
Key Takeaways
Online speed tests are generally accurate within 10-15% when done correctly. For best accuracy, use a wired Ethernet connection, close all other apps and tabs, and run the test 3 times at different times of day. The average gives you a reliable picture of your actual speed.
ISPs advertise "up to" speeds, meaning the maximum your plan can deliver under ideal conditions. WiFi overhead, network congestion, distance from the router, and the number of connected devices all reduce actual speeds. If your wired speed is less than 70% of your plan, contact your ISP.
Yes. A VPN adds encryption overhead and routes traffic through a remote server, which typically reduces speeds by 10-30%. Disconnect your VPN before running a speed test to see your true ISP speed.
Test monthly to establish a baseline, and whenever you notice performance issues. Testing at different times (morning, evening, weekend) helps identify ISP congestion patterns. Keep a log of results to present to your ISP if speeds consistently fall short.
Most residential ISP plans are asymmetric — they provide much faster download than upload speeds because most users consume more data than they send. Only fiber plans typically offer symmetric (equal upload/download) speeds. If you need faster uploads for video calls or streaming, look for fiber or business-class plans.
Yes. You can use this speed test tool on any device with a web browser. For the most accurate mobile results, stand near your router with a clear line of sight. Mobile speed tests over cellular (4G/5G) measure your carrier's network, not your home WiFi.
