4K Streaming Bandwidth Internet speed required for 4K HDR streaming

Two different numbers

Streaming services publish a recommended connection speed, and separately they deliver a video stream whose bitrate varies second by second. The two are easy to confuse. The recommended speed is a floor for staying in the top tier without buffering. The actual video bitrate is what the encoder chose for that scene, and it is usually lower. This entry lists the published figure for each service first, then the measured bitrates, then what it adds up to at home. For the disc comparison, see disc versus streaming bitrate.

What each service publishes for 4K

Netflix's help center lists 3 Mbps for HD (720p), 5 Mbps for Full HD (1080p), and 15 Mbps or higher for Ultra HD (4K). It also states data use per hour at the High setting: up to 1 GB for standard definition, up to 3 GB for HD, and up to 7 GB for 4K. Disney+ recommends 5.0 Mbps for high definition, 8.0 Mbps for live content, and 25.0 Mbps for 4K UHD content. Apple's support article for the Apple TV app recommends a minimum speed of 25 Mbps for 4K streaming, and says that if the connection is too slow, devices automatically switch to a lower-quality version.

Amazon's number comes from its Fire TV page rather than a Prime Video page: watching 4K Ultra HD needs a high-speed internet connection of at least 15 Mbps, and it adds that some video apps, for example Netflix, recommend at least 20 Mbps. The same page requires an Ultra HD TV with an HDMI input that supports HDCP 2.2 and HDCP 2.2 support in every device in the chain, including AV receivers and soundbars. Note that Amazon's 20 Mbps for Netflix is higher than Netflix's own 15 Mbps, so published figures differ even for the same service.

What streams actually run at

Real 4K streams are variable bitrate, so they are quoted as an average and a peak. A community database posted to the Blu-ray.com forums in March 2025, built from captures on an Apple TV developer panel and HDMI metadata read by an HDfury device, ranks the services. Apple TV+ averages 26 Mbps with a 37 Mbps peak. Max averages 21 Mbps with a 27 Mbps peak. Prime Video averages 19 Mbps with a 25 Mbps peak. Netflix averages 16 Mbps with a 28 Mbps peak. Disney+ averages 15 Mbps, and Paramount+ 12 Mbps. The poster reports titles from four regions (AU, CA, US, UK) and a margin of error of about 2%. Treat this as a careful community measurement, not an audit. Older FlatpanelsHD tests of Apple TV+ in 2019, relayed by Wccftech, measured the show See at 29 Mbps average and 41 Mbps peak, but Snoopy in Space at 13 Mbps average, which shows how much a single title can differ.

The two sets of numbers fit together. Netflix's 7 GB per hour for 4K is the same as an average of about 15.6 Mbps (7 times 8,000 megabits, divided by 3,600 seconds), which matches both its 15 Mbps recommendation and the 16 Mbps community average. At Apple's measured 26 Mbps average, an hour uses about 11.7 GB (26 times 3,600, divided by 8, divided by 1,000). Disney+'s 25 Mbps recommendation against a 15 Mbps measured average leaves wide headroom, and Disney+ does not say what the margin is for.

Streaming vs disc

A UHD Blu-ray is a different class of bitrate. Wikipedia's summary of the specification lists video data rates of 72 or 92 Mbit/s for a 50 GB disc and 92, 123, or 144 Mbit/s for 66 GB and 100 GB discs. Against the streaming averages above, the 92 Mbit/s disc rate is about 3.5 times Apple's 26 Mbps and about 6 times Netflix's 16 Mbps, and 144 Mbit/s is about 9 times Netflix's average. Streaming closes part of the gap with better codecs: Netflix reports that its AV1 sessions use one-third less bandwidth than both AVC and HEVC (see AV1). The remaining difference shows up as the artifacts covered in streaming compression artifacts and as banding in dark gradients.

Worked example: a household of simultaneous streams

Suppose one person watches Netflix in 4K (15 Mbps recommended), one watches Disney+ in 4K (25 Mbps), and one watches Apple TV in 4K (25 Mbps). The sum of the recommendations is 65 Mbps of sustained download, before a work video call, a game download, or a phone on Wi-Fi. A 100 Mbps plan covers that on paper and leaves 35 Mbps for everything else, but a 50 Mbps plan does not. Because services step the stream down rather than stop, an undersized link shows up as a drop from 4K to 1080p, which Netflix lists at 5 Mbps, not as a pause. Measure the speed on the device that plays the stream, because a fast router with a weak Wi-Fi link to the TV delivers the weak link's speed.

What else decides whether you get 4K

Bandwidth is one of several gates. Amazon's page requires an Ultra HD TV with an HDMI input that supports HDCP 2.2, and says every device in the chain must support it, including AV receivers and soundbars. Apple adds that 4K, HDR, and Dolby Vision titles need a device that supports the format, current software, and an internet connection fast enough for high-quality streaming. Choosing the box is its own decision; see best 4K streaming device and 4K streaming device.

Common confusions

Mbps is megabits per second, not megabytes. Divide by 8 for MB/s and multiply by 3,600 for megabits per hour, so 25 Mbps is about 11.25 GB per hour. A 4K stream is a sustained load, not a burst, so the figures above are speeds the link must hold for the whole show. For the cable and network side of the chain, see the HDMI cable guide.
