How to Read Speed Test Results

A speed test has four key metrics. Understanding them helps you diagnose problems and choose the right plan.

Download speed

Measured in Mbps. This is how fast you receive data. It affects streaming, browsing, and downloads. Higher is better.

Upload speed

Also in Mbps. Upload speed affects video calls, cloud backups, and sharing large files. Stable upload is critical for remote work.

Ping

Ping is latency in milliseconds. Low ping is essential for gaming and video calls.

Jitter

Jitter shows how much ping varies. High jitter causes stutter, robotic audio, and lag spikes.

What to do with your results

  • Compare Wi‑Fi vs Ethernet to isolate issues.
  • Run tests at different times to spot congestion.
  • Check multiple devices to see if the problem is local.

Quick Answers

Which metric matters most?

For most users, download speed matters for streaming, while ping and jitter matter for gaming and calls.

Why are my results different from my plan?

Plans are maximums. Wi‑Fi, device limits, and congestion can reduce real‑world performance.

How many tests should I run?

Run 2–3 tests at different times and compare averages, not single peaks.

What is the most common mistake?

Relying on a single test result or ignoring Wi‑Fi conditions is the most common mistake.
