How do I run an internet speed test with TestSpeed.app?

To run an internet speed test with TestSpeed.app, open your browser and go to https://testspeed.app. Optionally select a preferred test server or let us automatically pick the best one for you. Then click the Start Test button and wait a few seconds for your download, upload, and ping results to update in real time.

Why is my speed test result lower than expected?

If your speed test results are lower than expected, there are several common reasons. For the most accurate results, use a wired Ethernet connection instead of Wi‑Fi or move closer to your router, close background activity such as downloads, cloud backups, software updates, and streaming apps on all devices, and check with your ISP to confirm your subscribed speed and ask them to investigate any line issues, especially if you consistently see low results on fiber or cable.

What is a good internet speed?

A good internet speed depends on what you do online. As a general guideline: 1–5 Mbps is usually enough for basic browsing and email, 5–25 Mbps for HD video streaming, 25–50 Mbps for 4K streaming and online gaming, 50–100+ Mbps for households with multiple users and devices, and 100–500+ Mbps for heavy usage such as remote work, streaming, and gaming on several devices.

How accurate is TestSpeed.app?

TestSpeed.app is designed to provide fast, reliable, and repeatable internet speed test results. It uses multiple test servers worldwide for optimal routing, tests with real‑world file transfers instead of synthetic data, measures download speed, upload speed, latency (ping), jitter, and packet loss, and runs multiple sample measurements following industry‑standard testing methodologies. For the most accurate results, test on a wired connection and close other apps and devices that use the internet.

What factors affect my internet speed?

Several factors can affect your internet speed in tests and everyday use, including: your connection type (Fiber is usually faster and more stable than Cable, DSL, Satellite, or mobile data), network congestion at busy times of day, Wi‑Fi signal strength and interference from walls or other devices, the capabilities of your device and network adapter, background applications such as updates, streaming, and large downloads, the number of devices sharing your connection, possible ISP throttling or speed limits at peak times, and the quality and age of your router and modem.

What Do We Measure In An Internet Speed Test?

Download Speed

How fast information can transfer to you. It affects things like the duration it takes to download large files or display pages with many images. Download speed is measured in megabits per second (Mbps).

Upload Speed

How fast information can transfer from you. It affects things like how long it takes to post images to social media or send big files via email attachments. Upload speed is measured in megabits per second (Mbps).

Ping Speed

It is the reaction time of your internet connection - how fast you get a response after you have sent a request. A fast ping means a more responsive connection. Ping is measured in milliseconds (ms).

Your download, upload, and ping results will update in real time as the test runs.

If your results look slower than your plan, there are several common reasons. To get the most accurate results:

Use a wired connection: Connect your device to the router with an Ethernet cable. If you must use Wi‑Fi, move closer to the router or modem.
Close background activity: Pause downloads, cloud backups, software updates, and streaming apps on all devices while testing.
Check with your ISP: Confirm your subscribed speed and ask your provider to check for line issues, especially if you're on fiber or cable and consistently see low results.

“Good” internet speed depends on what you do online. As a general guideline:

Basic browsing & email: 1–5 Mbps
HD video streaming: 5–25 Mbps
4K streaming & online gaming: 25–50 Mbps
Multiple users & devices: 50–100+ Mbps
Heavy usage (remote work, streaming, gaming): 100–500+ Mbps

For the best experience, aim for a bit more speed than your typical daily usage requires.

For the most accurate results, test on a wired connection and close other apps and devices that use the internet.

Several factors can impact the speed you see in a test and in everyday use, including:

Connection type: Fiber > Cable > DSL > Satellite > Mobile data
Network congestion: Peak hours when many people are online
Wi‑Fi signal strength: Distance, walls, and interference from other devices
Device capabilities: Older devices or network cards may limit speed
Background applications: Updates, streaming, cloud sync, and large downloads
Number of connected devices: Bandwidth is shared across all devices
ISP throttling or limits: Some providers slow certain traffic or speeds at busy times
Router and modem quality: Older or low-end equipment may not support higher speeds
