Bandwidth vs Speed: What’s the Difference?

Bandwidth is the capacity of your connection, while speed is the rate data moves right now. Both affect your real-world experience.

A simple analogy

  • Bandwidth is the size of the pipe.
  • Speed is how fast the water flows at a given moment.

Why it matters

  • Higher bandwidth supports more devices at once.
  • Speed tests show current performance, not maximum capacity.

How to read ISP plans

  • Plans advertise maximum bandwidth, not guaranteed speeds.
  • Check peak-time performance and upload limits.
