What Internet Speed Do I Need at Home?

The internet speed you need depends on what runs at the same time in your home, not on the biggest number in a plan. Add up the activities that happen together, then keep some room on top. This guide shows the numbers that streaming services and video call tools publish, explains download speed, upload speed and bandwidth in plain words, and gives you a simple way to check your own line with the SpeedIQ speed test.

Speed is measured in Mbps (megabits per second). One megabyte per second equals 8 Mbps, so a plan of 100 Mbps moves at most about 12.5 MB of data per second. Providers sell their plans by this number, so it helps to know what it means before you pick one.

How Much Internet Speed Do You Need for Streaming?

Video streaming needs 3 Mbps for HD, 5 Mbps for full HD and 15 Mbps for 4K on Netflix. These are the speeds per stream that Netflix recommends in its Help Center (2026). If two people watch 4K on two TVs at once, you need at least 30 Mbps for the video alone.

ActivitySpeed per deviceSource
Netflix in HD (720p)3 Mbps or higherNetflix Help Center, 2026
Netflix in full HD (1080p)5 Mbps or higherNetflix Help Center, 2026
Netflix in 4K15 Mbps or higherNetflix Help Center, 2026
Microsoft Teams video callHD video in under 1.5 MbpsMicrosoft Learn, 2026

Other streaming services publish their own values, so check the help page of the service you use. The numbers above are a good guide for the size of the problem: streaming in 4K is the heaviest everyday use in most homes.

What Internet Speed Do You Need for Video Calls and Working From Home?

A video call needs much less than a 4K stream. Microsoft states that Teams can deliver HD video quality in under 1.5 Mbps and lowers video quality before audio quality when bandwidth is short (Microsoft Learn, 2026). Other tools publish their own values, so look at the support page of your tool.

For work from home, upload speed matters more than people expect. In a video call your camera sends video to the other side, so the call uses your upload speed in the same way as it uses your download speed. Large file uploads, cloud backups and screen sharing add to this. If your upload speed is very low, calls get blurry or freeze even when downloads are fast.

Download Speed vs Upload Speed: What Is the Difference?

Download speed is how fast data comes to your device. Upload speed is how fast data leaves your device. Most plans give you far more download than upload, which suits watching, browsing and gaming, but not heavy uploading.

  • Download speed: streaming, web pages, game downloads, app updates.
  • Upload speed: video calls, sending large files, cloud backups, live streaming.

Cable and DSL plans often have a much smaller upload than download. Fiber plans are often symmetrical, which means both values are equal. The article Fiber vs Cable Internet compares both types in detail.

What Is Bandwidth, and How Is It Different From Speed?

Bandwidth is the most data your connection can carry per second. In everyday use, people use "bandwidth" and "internet speed" for the same thing. Your whole household shares this bandwidth. When one person starts a large download, the rest of the home has less left. This is why the same line feels fast at noon and slow in the evening, when many devices are active. You can read more about this in Why Is My Internet Slow at Night?

How Do I Work Out My Own Number?

Add the speed of every activity that can run at the same time, then add some headroom. The example below is an assumption for a household of four, not a measured value:

At the same timeSpeed (assumption based on the table above)
Two 4K streams (2 × 15 Mbps)30 Mbps
One HD video call for workabout 1.5 Mbps
One full HD stream on a tablet5 Mbps
Phones, smart home devices, updatesplan about 10 Mbps for these
Totalabout 47 Mbps

The last row for phones and smart devices is a rough planning value, not a published figure. Round the total up and add a reserve, because the real speed of a line is often lower than the plan on the contract. The next section shows how to see your real value.

How Do I Test the Internet Speed I Get?

Run a speed test on a device that is connected by cable or sits close to the router, and close other apps first. Open the SpeedIQ speed test, press start and read the download, upload and ping values. Run it two or three times at different times of the day. Compare the numbers with the sum from the section above.

The full test steps are in How to Test Internet Speed. A browser speed test shows what reaches your device at that moment. It does not show the speed of every other service on the internet.

What Is a Good Internet Speed Today?

The US regulator FCC set the benchmark for fixed broadband at 100 Mbps download and 20 Mbps upload in its 2024 Section 706 Report. Before that, the benchmark was 25 Mbps download and 3 Mbps upload, set in 2015. This is a policy value for what counts as advanced broadband in the United States, not a rule for your home. It still helps as an orientation: a line at or above 100/20 Mbps meets this benchmark.

Which Plan Should You Choose?

Choose the plan that covers your own total with a reserve, and look at upload speed, not only download speed. Every extra user, 4K screen or video call raises the total. If you are unsure, start with the smaller plan, test it for a month with the SpeedIQ speed test and change when the numbers show a need. Plans on different types of lines behave differently, so compare 5G home internet and fiber if both are offered at your address.

Summary

Add up what runs at once: 15 Mbps per 4K stream, 5 Mbps per full HD stream, under 1.5 Mbps for an HD video call. Add headroom, check upload speed and test the line you really get.

FAQ

What internet speed do I need for 4K streaming?

Netflix recommends 15 Mbps or higher for 4K (Netflix Help Center, 2026). If two TVs stream 4K at the same time, plan for at least 30 Mbps for the video alone.

Is 150 Mbps enough for 2 people?

Yes, for typical use. Two 4K streams need about 30 Mbps and an HD video call needs under 1.5 Mbps, so 150 Mbps leaves a large reserve. The values come from the table above; your own use may differ.

Is 1000 Mbps fast or slow?

1000 Mbps is ten times the 100 Mbps download benchmark the FCC set in 2024. It is far more than most homes use at one time. A fast plan only helps if your router, cables and Wi-Fi can carry it.

What upload speed do I need for working from home?

An HD video call needs under 1.5 Mbps in Microsoft Teams (Microsoft Learn, 2026). Screen sharing, large uploads and cloud backups need more. Run a speed test and check your upload value, not only the download value.

Why is my internet slower than my plan?

Common reasons are weak Wi-Fi, many devices at the same time and busy hours. Test with a cable first. If the cable result is also far below your plan, contact your provider with your test results.
