How Many Mbps Do I Need for 4K Streaming?

4K streaming needs more bandwidth than most people expect — especially if multiple people are watching at the same time.

Updated 2026

  1. 1

    Netflix 4K

    Netflix recommends 25Mbps per 4K stream. With HDR enabled it can use more. Multiply by the number of simultaneous 4K screens in the house.

  2. 2

    YouTube 4K

    YouTube's 4K (2160p) stream runs at roughly 20Mbps. HDR and 60fps content pushes higher.

  3. 3

    Disney+, Apple TV+, Amazon Prime

    These services recommend 25Mbps for 4K UHD. Disney+ with IMAX Enhanced can peak higher.

  4. 4

    Add up your household

    A household with two 4K streams + gaming + video calls needs at least 80–100Mbps to stay comfortable. Factor in smart home devices too.

  5. 5

    Check your actual speed

    Run a speed test — your plan's advertised speed and your actual speed can differ, especially on WiFi. Wired connections get reliably closer to the plan speed.
