What Internet Speed Does Netflix Need?

Article Summary

• Netflix's minimum speed requirement is 3Mbps for a single stream in standard definition (SD).
• For optimum quality, Netflix recommends speeds of at least 5Mbps for HD streaming, and 25Mbps to stream in 4K.
• If you plan to connect multiple devices at once, you'll want an even faster internet plan to accommodate the higher bandwidth consumption.

To avoid getting caught in buffering loop during the finale of Great British Bake Off, you'll need a strong internet speed that supports your Netflix (and sugar) addiction. But exactly what internet speed is required for Netflix? And what streaming speed is best for your household in particular? 

In this guide, we'll give you the minimum Netflix internet speed requirements to get you up and running, as well as highlight some additional factors that determine your internet speed and point you toward the best internet plans for streaming Netflix and using other streaming services.

Netflix Minimum Speed Requirements

The bare minimum download speed to get Netflix up and running is a mere .5Mbps, but that won't result in a smooth streaming experience by a mile. For a decent stream on a single device, Netflix recommends download speeds of at least 3Mbps for standard definition quality.

Most households these days have high-definition televisions, which means you'll likely want to optimize your internet speed for HD streaming. Netflix recommends at least 5Mbps download speed to stream in HD—but if you really want to see the clearest and smoothest picture, a broadband connection of at least 25Mbps is best to support ultra-high-definition/4K video.

That said, it isn't as simple as choosing an internet plan that maxes out at 25Mbps. Netflix doesn't account for a number of other factors that affect your internet connection speed, so these minimums are likely below the threshold you'll actually need to stream without issue.

Other Streaming Service Speed Requirements

Netflix is just one of many streaming services out there, including live TV streaming services like YouTube TV or Hulu Live that require even higher speeds for optimal viewing. Here are the minimum streaming speed requirements for a few of the other top dogs.

How to Check Your Netflix Speed

You can quickly figure out how fast your streaming connection speed is right from your Netflix app—in fact, it takes just two steps: 

1. Navigate to your Settings menu.
2. Select the "Check Your Network" option.

Netflix will confirm that your network connection is strong and run a speed test to see how fast your streaming connection is. In fact, it's a good idea to run an internet speed test in general, to make sure your connection is performing as expected whether you're streaming or not. You can pinpoint if slow internet speed is being caused by your router, your internet service provider, or if Netflix is simply experiencing a temporary outage.

Factors Affecting Your Netflix Speeds

A number of things will affect your Netflix speeds, including your internet plan's maximum download speeds, the number of devices currently connected to your internet, and the kinds of activities those devices are performing (like streaming video vs. checking email, for example). More devices performing higher-bandwidth activities all at once will slow down your Netflix streaming speed. And if you’re anything like us here at WhistleOut, you likely subscribe to multiple audio and video streaming services.

For these reasons, the best internet speeds for Netflix are a bit higher than those the streaming service lists. Here's what we recommend.

Netflix Streaming Bandwidth Usage

If your internet connection is fast enough for HD or ultra HD streaming (at least 5-25Mbps), you'll get the sharpest picture and ultimately a better experience. But note that the higher your stream quality, the more bandwidth you'll take up. Netflix's video settings typically default to "Auto," choosing the optimal quality detected for your internet connection, but you may wish to bump yours lower or higher. 

You can adjust your video quality in your Netflix settings menu, and choose either low or medium quality to save on data usage. You can also download Netflix content directly to your device to watch offline if you have access to the Netflix app, but be aware that this will also take up additional bandwidth on your computer or phone.

Best Internet Plans for Netflix

The best way to ensure your stream is buffer-free and avoid worrying about your data consumption is to get an unlimited internet plan with a connection speed of at least 50Mbps. That leaves you free to watch Planet Earth in all the glorious detail it deserves, while your family or roommates continue to simultaneously use their devices to—well, do whatever it is they do.

Here are a few of the top home internet plans featuring unlimited data and HD-compatible speeds.
