Internet Speed Test
Internet Speed Test is part of Toolspire and is ready as soon as this page loads. Find out how fast your connection really is: download and upload in Mbps, ping and jitter, how much lag rises when the line is busy, and whether it’s good enough for 4K video, video calls and gaming.

What you can do here
All the numbers that matter
Download, upload, ping, jitter and loaded latency — not just one big number.
Live gauge
Watch the speed as it is measured, from a quick ping to the full download and upload runs.
Bufferbloat grade
See whether calls and games will lag while someone else downloads, graded A+ to F.
Mobile-data friendly
Data saver mode keeps a test under about 39 MB, and you can stop at any moment.
What it’s good for
Plain ratings for streaming, video calls, gaming, browsing and uploading files.
Your history
Compare Wi-Fi with cable, or morning with evening — recent results stay in this tab.
The sequence
How to test your internet speed
- 1
Close heavy apps
Pause downloads, streaming and cloud backups on all devices so they don’t share the line during the test.
- 2
Press Start
Choose Full test, or Data saver on mobile data, and press Start. Ping is measured first.
- 3
Wait for both runs
Download and then upload are measured, which takes 15–30 seconds on most connections.
- 4
Read the results
Compare download and upload with your plan, check the ratings, and copy the results to share with your provider.
Worth knowing
- Internet Speed Test on Toolspire: measures download and upload speed in Mbps, ping (latency) and jitter, plus loaded latency — how much ping rises while the line is busy (bufferbloat).
- Tests against Cloudflare’s global network (speed.cloudflare.com), usually from a data centre in or near your city; the page shows which one.
- Leaves out connection set-up and server processing time, and reports the 90th-percentile speed of many transfers — the line’s real capacity rather than its slow start.
- File sizes grow only while transfers stay quick, and Data saver caps a run at about 39 MB for mobile data.
- Rates the connection for 4K streaming, video calls, online gaming, browsing and uploads, and shows which data centre answered, your country and your IP address.
- Keeps your last 20 results in this browser only. No app or account is needed, and Toolspire never sees your results.
What the results mean
| Result | What it measures | Good value |
|---|---|---|
| Download | How fast data reaches you — streaming, browsing, downloads | 25 Mbps+ for 4K; 100 Mbps+ for busy homes |
| Upload | How fast you send data — video calls, uploads, cloud backup | 5 Mbps+ for HD calls; 20 Mbps+ for creators |
| Ping | Round-trip time to the server, in milliseconds | Under 30 ms great, under 100 ms fine |
| Jitter | How much ping varies from one moment to the next | Under 10 ms for gaming, under 30 ms for calls |
| Loaded latency | Ping while the line is busy downloading or uploading | Within 30 ms of the idle ping (grade A) |
Why your speed may be lower than your plan
- Wi-Fi: walls, distance and older routers or phones cut speed. Test with a cable, or close to the router on 5 GHz, to see what the line delivers.
- Other devices: TVs, updates and backups on the same connection share the bandwidth during the test.
- Peak hours: evenings are busiest, especially on mobile networks and shared fibre.
- VPNs and proxies add distance and encryption overhead.
- Very fast plans: above roughly 1 Gbps, the browser and device can become the limit rather than the line.
