How Much Speed Do You Need for 4 TVs Streaming 4K Simultaneously?

The Multi-User Bandwidth Equation

ISPs market Gigabit to families who don't need it. Let's do the actual math.

Bandwidth Per Device (Real Numbers)

• 4K UHD (Netflix/Prime Video): 25 Mbps
• 1080p HD Stream (YouTube/Hulu): 5–8 Mbps
• Zoom/Teams 1080p call: 4 Mbps download + 4 Mbps upload
• Competitive gaming (Valorant, COD): 5 Mbps (low latency required)
• Smart home background overhead: 10 Mbps

Scenario A: The Busy Evening

4K Netflix (25 Mbps) + gaming (5 Mbps) + 1080p YouTube (8 Mbps) + Zoom call (4 Mbps) + smart devices (10 Mbps) = 52 Mbps total. A standard 100 Mbps plan handles this comfortably with headroom. Gigabit provides zero improvement.

Scenario B: 4 Simultaneous 4K TVs

4 × 4K Netflix (25 Mbps each) = 100 Mbps total. A 200–300 Mbps plan handles this with room to spare for background updates. Still no reason for Gigabit.

The Only Genuine Reason to Pay for Gigabit

Large file downloads. A 150 GB PS5 game takes 3.5 hours on 100 Mbps and 20 minutes on 1 Gbps. If your household regularly downloads large game files, software updates, or 4K video projects — Gigabit is genuinely worth it. For streaming alone, a 300 Mbps plan is more than adequate for any household.
