Download Speed
The rate at which data travels from the internet to your device, measured in megabits per second (Mbps).
What download speed means
Download speed measures how fast data travels from the internet to your device. When you open a webpage, stream a video, or receive an email attachment, your device is downloading data. The faster your download speed, the quicker that data arrives.
Download speed is measured in megabits per second, written as Mbps. One megabit equals one million bits. It is important to note that megabits (Mb) and megabytes (MB) are different. A megabyte is eight megabits. So a 100 Mbps connection transfers about 12.5 megabytes of data per second.
Most internet plans are described primarily by their download speed because most users consume far more data than they send. Streaming a 4K video requires about 25 Mbps of continuous download speed. Browsing the web requires far less, typically under 5 Mbps for a smooth experience.
Why download speed matters for your connection
Download speed directly affects your day-to-day experience. Slow download speeds cause videos to buffer, web pages to load sluggishly, and large file transfers to take much longer than they should. For households with multiple people streaming or working from home at the same time, download speed needs to be high enough to serve everyone at once. For comparison, see upload speed.
Not all activities need the same download speed. Email and basic web browsing need very little. 4K streaming, large game downloads, and remote desktop connections need considerably more. Knowing what your household does online helps you choose the right plan.

Common questions about download speed
For a single user, 25 Mbps is adequate. For a family of four with multiple streams and a work-from-home setup, 100-200 Mbps is more comfortable. The FCC considers 25 Mbps the minimum for broadband, though many households benefit from more.
ISPs advertise maximum speeds. Your actual speed depends on your equipment, connection type, how many devices are active, and network congestion. Testing over Ethernet instead of Wi-Fi usually gives a more accurate reading of your true download speed.
They are measured separately. Most home internet plans are asymmetric, meaning download speeds are much higher than upload speeds. Fiber plans often offer symmetrical speeds where download and upload are equal.
