What Is Bandwidth?
This page explains this metric in plain language, what a healthy value looks like, and how it appears on a speed test result.
How this speed test works
In plain terms, this page explains what a specific part of your speed-test result means and what a good value looks like in practice.
On any speed test, what is bandwidth? is reported alongside the other core metrics so you can evaluate the connection as a whole rather than by a single headline number.
Understanding download vs upload
Streaming cares about sustained download, gaming cares about latency, and creators care about upload — the right metric depends on what you do online.
Almost no real application needs the peak number on your plan; what matters is whether your connection keeps a steady, low-latency throughput during the hours you actually use it.
Making the result useful
A good mental model: throughput is how much data can flow, and latency is how quickly each packet arrives; both matter, but they answer different questions about your internet.
Practically, this number appears alongside download, upload and jitter so you can judge a connection as a whole rather than as a single headline figure.
Seeing the number that matters most to you — and knowing what a healthy value looks like — turns a confusing result screen into an actionable one.
Making the result useful
What Is Bandwidth? is defined precisely above; the fastest way to see it on your own connection is to run the test and read the matching line on the result screen.
Speed test limitations
A speed test measures your connection to our test server, which typically lives on the same backbone your ISP peers with. Speeds to other destinations can vary with routing, server load, and the websites you use.
Latency shown here is the round-trip time to the test server, not the latency you would get to every gaming server or streaming CDN. Use it as a general baseline, not a guarantee.
