Streaming Speed Test | FastSpeedTest
Screen counts assume nothing else is using the connection. Downloads, game updates and calls on other devices take from the same total.
The report divides your measured download by a planning figure for each quality: 3 Mbps for 720p, 5 Mbps for 1080p and 25 Mbps for 4K. Those figures sit a little above what services ask for, because real homes rarely have the whole line free for video.
Run this test on a phone or laptop in the same room as your TV. If the result is much lower than next to the router, Wi-Fi is the bottleneck, not your plan. A cable or a mesh point near the TV usually fixes it. You can compare the two tests side by side.

Frequently asked questions
- How much speed do I need for 4K streaming?: Streaming services ask for roughly 15 to 25 Mbps per 4K screen. Planning 25 Mbps per screen leaves headroom so the picture does not drop in quality when others use the connection.
- Why does my video buffer on a fast plan?: Usually Wi-Fi. A TV far from the router can get a fraction of the plan speed. Test from the room where the TV is, or connect the TV with a cable.
- Does ping matter for Netflix or YouTube?: Only a little. It changes how quickly a video starts, but the player buffers ahead, so quality depends on download speed.
- How many screens can stream at once?: Divide your download by the per screen figure: about 5 Mbps for 1080p and 25 Mbps for 4K. The report above does this for your result.
