How Much Internet Speed Do I Need for IPTV?

The short answer

For one screen, IPTV needs about 10 Mbps for HD and about 25 Mbps for 4K. Add the same again for every other screen that watches at the same time, then leave some room for phones, laptops and downloads. Most home broadband in the USA, the UK and Europe is well above that, so the line itself is rarely the problem; Wi-Fi inside the house usually is.

Speed per screen

Picture quality	Speed per screen	Data per hour (approx.)
SD (standard definition)	3 to 5 Mbps	about 1 GB
HD (720p / 1080p)	about 10 Mbps	1.5 to 3 GB
4K (2160p)	about 25 Mbps	7 GB or more

These figures are the same ballpark that the big streaming services publish for their own apps; see, for example, Netflix's internet speed recommendations. Live TV is a little more demanding than on-demand video because the player can't load far ahead, so a small margin above these numbers helps.

How to count several TVs

Add up every screen that watches at the same time, then add about 20 to 30 percent for everything else on the line.

One HD TV: 10 Mbps, so a 15 to 20 Mbps line is comfortable.
Two HD TVs and a phone: 10 + 10 + 5 = 25 Mbps, so aim for 30 to 35 Mbps.
One 4K TV and two HD screens: 25 + 10 + 10 = 45 Mbps, so aim for 55 to 60 Mbps.

The US Federal Communications Commission has a useful broadband speed guide that shows how much speed common household activities need, if you want to plan for the whole family.

How to test your speed properly

Run the test on the device you watch on (the TV, Firestick or box), not on your phone. A phone next to the router can show 200 Mbps while the TV in the next room gets 8.
Test in the evening, between 8 and 10 pm, when your internet provider is busiest.
Test twice: once on Wi-Fi and once with a cable, if you can. The difference tells you whether Wi-Fi is the bottleneck.

Fast line but still buffering?

If the speed test is fine but the picture still stops, the problem is usually Wi-Fi range, an old device, or the app. Our article on how to fix IPTV buffering walks through ten fixes in order, starting with the two that solve most cases: a cable to the TV and a restart in the right order.

What if my line is slower than 10 Mbps?

Choose the SD or HD version of a channel instead of FHD or 4K.
Pause downloads and cloud backups while you watch.
Use one screen at a time, and pick a 1-device plan.
Ask your provider whether a faster plan is available at your address; in many areas the upgrade costs less than a cable TV package.

Try it on your own line

Numbers only tell you so much. The honest test is to watch on your own TV, on your own internet, at the busiest time of day. SilyaTV's free 36-hour trial needs only an email address, so you can check a live match in the evening before you pay anything. Setup takes 5 to 15 minutes with the guide for your device.

Common questions

Is 10 Mbps enough for IPTV?

Yes, for one screen in HD. For two screens or 4K you need more: about 10 Mbps per HD screen and 25 Mbps per 4K screen.

How much data does IPTV use per hour?

Roughly 1.5 to 3 GB per hour in HD and 7 GB or more in 4K.

Is Wi-Fi or Ethernet better for IPTV?

Ethernet. A cable from the router to the TV or box gives the steadiest picture, because TV Wi-Fi antennas are often weak.

Does IPTV work on mobile data?

Yes, but it uses a lot of data. Use Wi-Fi when you can, or choose a lower quality.
