Internet speed is measured in megabits per second (Mbps), and it's the number providers put front and center in their marketing. But more speed isn't automatically better for your situation — it's only worth paying for if you'll actually use it. The right question isn't "what's the fastest plan?" It's "how do the people in my home use the internet at the same time?"
What uses the most bandwidth
Different activities have very different appetites. As a rough guide for a single activity:
- General browsing, email, music: 1–5 Mbps
- HD video streaming: 5–8 Mbps per stream
- 4K video streaming: 15–25 Mbps per stream
- Video calls: 2–4 Mbps for good quality
- Online gaming: modest bandwidth (3–6 Mbps), but low latency matters more
- Large downloads / cloud backups: as much as you can give them
The key word is simultaneous. A household isn't doing one thing at a time — someone streams 4K while another person is on a video call and a third downloads a game update. You add those up to estimate a realistic peak.
A simple way to size your plan
- Count the people who use the internet heavily at the same time.
- Estimate the most demanding things happening at once (e.g., one 4K stream + two video calls).
- Add the bandwidth for those activities, then add a buffer of 50–100% for smart-home devices, updates, and headroom.
Rule of thumb
For many households, 100–300 Mbps comfortably covers streaming, working from home, and gaming for several people. Gigabit plans shine for large households, frequent big downloads, or heavy uploaders — but plenty of people pay for speed they never touch.
Don't forget upload speed and latency
Advertised speeds usually refer to download. If you upload a lot — video creators, cloud backups, frequent large file shares — upload speed matters, and this is where fiber tends to pull ahead of cable. For gaming and video calls, latency (the delay before data starts moving) and consistency matter more than raw Mbps.
The bottom line
Match the plan to how your household actually uses the internet, leave some headroom, and don't pay for a number you'll never reach. If you're unsure, start a tier lower than you think — it's usually easy to upgrade later if you notice slowdowns.
