For 4K streaming, what is the recommended target Mbps?

The recommended target Mbps for 4K streaming is generally considered to be around 25 Mbps, but aiming for higher bandwidth, such as 35 Mbps, is often suggested to ensure a buffer-free and more reliable streaming experience. However, the variability in internet quality and potential fluctuations can impact the actual performance.

By targeting 45 Mbps, which is the chosen answer, you ensure that you are accommodating for peak usage times, fluctuations in your internet speed, and the additional bandwidth needed if multiple devices are using the network simultaneously. This higher bandwidth can help deliver smoother playback, higher quality, and fewer interruptions in the streaming experience, making it more suitable for 4K content that demands a substantial amount of data for the best quality.

For optimal experience, having a buffer above the minimum requirement provides a safety net, especially if the streaming service used has specific encoding or bitrate requirements that exceed the basic needs. Therefore, while lower speeds can work under ideal conditions, 45 Mbps is a more prudent choice to guarantee consistent, high-quality 4K streaming.
