What internet speed do you need for 4K streaming?
Each service's own 4K recommendation, how much speed a whole household needs, and why 4K still buffers on a fast plan.
One 4K stream needs about 15 to 25 Mbps: Netflix recommends 15 Mbps, YouTube 20 Mbps, and Disney+ and Apple TV 25 Mbps, while Max recommends 50 Mbps for its best 4K. Add that up for every TV that might stream at once and leave room for everything else; for most households, a 100 to 300 Mbps plan is plenty. If 4K still buffers, the cause is usually Wi-Fi, not your plan.
4K speed by service
Recommendations from each service's help pages, as compiled by T-Mobile, Allconnect and HighSpeedInternet.com; Prime Video figures differ between sources.
| Service | 4K recommendation | Also needed |
|---|---|---|
| Netflix | 15 Mbps | Premium plan |
| YouTube | 20 Mbps | 4K video and a 4K device |
| Disney+ | 25 Mbps | A plan and title in 4K |
| Apple TV | 25 Mbps | 4K device |
| Max (HBO Max) | 25 Mbps minimum, 50 Mbps recommended | Ultimate plan |
| Prime Video | About 15 to 25 Mbps | Prime membership |
| YouTube TV | 25 Mbps | 4K Plus add-on |
Netflix lowered its 4K recommendation from 25 Mbps to 15 Mbps as its video compression improved, which is why older articles still quote 25. Live 4K sports tend to need more than movies; plan on about 25 Mbps.
How much speed your household needs
Add the streams you might run at the same time, then add room for everything else. Video calls use 2 to 4 Mbps each, gaming 5 to 25 Mbps, and phones, cameras and updates take more in the background.
| Household | Example | Plan to look for |
|---|---|---|
| One 4K TV | One person streaming, browsing | 50 to 100 Mbps |
| Two to three 4K TVs | Family streaming at night | 100 to 300 Mbps |
| Busy home | 4K TVs, gaming, video calls, uploads | 300 Mbps to 1 Gig |
Example: three people streaming Netflix in 4K (3 × 15 = 45 Mbps), two gaming (about 40 Mbps) and two on video calls (about 10 Mbps) add up to roughly 95 Mbps, so a 200 or 300 Mbps plan leaves comfortable headroom. Our internet speed guide has a fuller breakdown.
Why 4K buffers on a fast plan
- Wi-Fi. The speed reaching the TV can be a fraction of your plan. Test on the TV itself, use 5 GHz Wi-Fi, or plug the TV or streaming device into Ethernet; see Ethernet vs. Wi-Fi.
- The streaming device. Older sticks and TV apps struggle with 4K HDR. A newer streaming device often fixes it.
- Evening congestion. Cable, 5G home and satellite networks can slow at peak times. Run a speed test at 8 p.m. to see.
- A VPN. Routing through a distant server cuts speed; turn it off or choose a nearby server.
- The plan tier. Netflix only streams 4K on Premium, and other services limit 4K to higher tiers.

Device and connection requirements
- A 4K TV, or a 4K TV plus a 4K streaming device.
- An HDMI port and cable that support HDCP 2.2, usually labeled HDMI 2.0 or later; most current gear does.
- For HDR (Dolby Vision or HDR10), a TV and title that support it.
- For 4K over Wi-Fi, a router on Wi-Fi 5 or newer, close enough to the TV.
How much data 4K uses
4K streaming uses roughly 7 GB an hour on Netflix, more on services with higher bitrates. Four hours a night adds up to about 850 GB a month, which matters on plans with data caps: Xfinity applies a 1.2 TB cap in many areas, and some 5G and satellite plans slow you after a set amount. See data caps explained and unlimited home internet.
Best internet types for 4K
Fiber and cable easily handle several 4K streams. 5G home internet usually works well but can slow in the evening, and satellite can stream 4K with Starlink but rarely with older services. Our best internet for streaming guide compares providers.
Questions
What internet speed do I need for 4K?
About 15 to 25 Mbps per 4K stream: Netflix recommends 15 Mbps, YouTube 20 Mbps, and Disney+ and Apple TV 25 Mbps.
Is 100 Mbps enough for 4K streaming?
Yes. 100 Mbps handles three to four 4K streams with room for browsing, if your Wi-Fi delivers that speed to the TV.
Why does Netflix say 15 Mbps when others say 25?
Netflix lowered its recommendation from 25 Mbps as its compression improved. Other services still recommend 20 to 25 Mbps.
Why does my 4K stream keep buffering?
Usually weak Wi-Fi at the TV, an older streaming device, or evening congestion. Test speed on the TV and try Ethernet.
How much data does 4K streaming use?
Roughly 7 GB an hour on Netflix, and more on services with higher bitrates.
Do I need a special Netflix plan for 4K?
Yes. Netflix streams 4K only on its Premium plan, whatever your internet speed.
