Estimate home internet speed by adding the needs of activities happening at the same time. Netflix recommends a stable connection of at least 15 Mbps for one 4K stream; Microsoft recommends 4 Mbps down and 2.5 Mbps up for each Teams video endpoint.
What Netflix and Teams recommend
Netflix recommends a stable connection of at least 3 Mbps for 720p, 5 Mbps for 1080p, and 15 Mbps for 4K. Those figures apply to streaming at each video quality, not to every activity happening in your home at once.
Microsoft’s recommendation for Teams meeting video is 4 Mbps download and 2.5 Mbps upload per endpoint. That usually means one computer or mobile device per person. If someone joins the same meeting on a computer and a phone, Microsoft counts two endpoints. Actual bandwidth varies with the video layout, resolution, and frame rate.
When bandwidth is limited, Teams prioritizes audio and can provide HD video below 1.5 Mbps. That adaptive behavior is not the recommended bandwidth target for every call.
Add the activities happening at once
For one Netflix 4K stream alongside two Teams video endpoints, the illustrative calculation is:
- Download: 15 + (2 × 4) = 23 Mbps
- Upload: 2 × 2.5 = 5 Mbps for the Teams endpoints
This is arithmetic based on the services’ recommendations, not a measurement of a household or a universal plan recommendation. Add the needs of the uses that overlap, and keep download and upload separate.
Check the speed at the device
An advertised plan rate does not guarantee that every device will receive that speed over Wi-Fi. The speed reaching a device also depends on local network conditions.
Netflix recommends checking the connection on the device you use to stream. On a phone, tablet, or computer, open Fast.com in a browser; on a TV, use the speed check in the Netflix app.
