What internet speed do I need?

Start with service-specific inputs

For on-demand video, use the selected service’s requirement for the resolution you watch. Netflix recommends 15 Mbps or higher for its 4K service. That is one service’s guidance, not a universal bitrate for every 4K video or a complete household requirement.

Video you send needs upload capacity too. For example, Zoom’s bandwidth guidance lists 3.8 Mbps upload and 3.0 Mbps download for 1080p video. Meeting mode and settings matter. Cloud gaming, a live broadcast and playing a locally rendered game are different workloads; do not assign them one generic gaming rate.

Worked example: separate both directions

Assume two video streams are budgeted at 20 Mbps download each, while two calls are budgeted at 4 Mbps in each direction. These are chosen planning assumptions, not service guarantees. Concurrent demand is 2 × 20 + 2 × 4 = 48 Mbps down and 2 × 4 = 8 Mbps up.

An illustrative 25% margin gives 60 Mbps down and 10 Mbps up. That margin is a modelling choice, not a technical standard. Add other active work, revise app assumptions and compare with sustained measured capacity. An idle phone does not need the same allowance as an active stream.

Treat large-file deadlines as another calculation

A backup that can run overnight may be flexible; a large upload due in twenty minutes is not. A 10 GB decimal file contains 80,000 megabits. At a constant useful upload of 20 Mbps, its ideal transfer time is 4,000 seconds, or 1 hour 6 minutes 40 seconds. At 100 Mbps it is 800 seconds, or 13 minutes 20 seconds.

Those times assume the stated useful transfer rate with no competing workload. Storage, processing and remote-service limits can add time. Use the bits, bytes and transfer-time guide rather than treating the advertised download headline as an upload rate.

Capacity alone does not settle call or gaming quality

Once an application has enough capacity, additional Mbps may provide little benefit to its responsiveness. Delay, variation in delay, loss, Wi-Fi conditions and the application service can still matter. Compare idle and loaded latency alongside the actual symptom.

A fast wired result and poor performance in one room suggest investigating the local wireless path. A consistently low wired result warrants checking device and Ethernet limits, the endpoint and service performance. Neither observation alone identifies the fault.

Compare packages against your evidence

1. List the activities at your real busy time, including outgoing video, cameras and backups.
2. Find app-specific rates and model only the activities that overlap.
3. Check file-transfer deadlines separately and allow a clearly stated margin.
4. Compare download and upload specifications, address-specific estimates and your own repeat tests.
5. Review total contract cost, terms, reliability and support before selecting a tier.

The internet speed planner helps explore editable assumptions. Its peak recommendation searches 07:00 to midnight, so overnight deadlines need a separate check. A model is an estimate; it cannot certify a package or guarantee a particular room’s Wi-Fi performance.
