What Internet Speed Do I Need? A Simple Guide
Most homes need far less speed than ISPs advertise. Here is how many Mbps you actually need.
Internet providers sell plans by download speed in Mbps. Most homes need less than they think, but upload speed and WiFi quality matter just as much.
Internet providers sell plans by download speed in Mbps. Most homes need less than they think, but upload speed and WiFi quality matter just as much.
As a rough guide, allow about 25 to 50 Mbps per person who streams or works online: 50 to 100 Mbps for 1 to 2 people, 100 to 300 Mbps for 3 to 4 people, and 300 Mbps to 1 Gbps for 5 or more people or heavy users.
Here is a simple way to choose.
Speed needed by activity
| Activity | Download per stream | Upload |
|---|---|---|
| Web and email | 1 to 5 Mbps | 1 Mbps |
| HD video streaming | 5 to 8 Mbps | Minimal |
| 4K streaming | 15 to 25 Mbps | Minimal |
| Video calls (HD) | 3 to 4 Mbps | 3 to 4 Mbps |
| Online gaming | 3 to 10 Mbps | 1 to 3 Mbps, low ping matters more |
| Large game downloads | As fast as possible | Minimal |
The upload column is the one I point people at first.
Speed by household
| Household | Suggested plan |
|---|---|
| 1 to 2 people, light use | 50 to 100 Mbps |
| 3 to 4 people, streaming and calls | 200 to 300 Mbps |
| 5+ people, 4K and gaming | 500 Mbps to 1 Gbps |
| Creators uploading large files | Fiber with fast upload |
I start from the household, not the plan, when someone asks me what to buy.
Why your WiFi may not match your plan
- Old routers cap speeds below your plan.
- 2.4 GHz and distance cut speed sharply.
- Older devices with WiFi 4 adapters cannot reach high speeds.
- Run tests on Ethernet to see your real plan speed.
An old router is the bottleneck I find most often in homes like this.
Upload speed is easy to overlook
Plans are advertised by download speed, but upload speed decides how good your video calls look and how quickly backups and uploads finish.
- Video call in HD: about 3 to 4 Mbps upload per person on a call.
- Streaming to Twitch or YouTube: 6 to 10 Mbps for 1080p.
- Cloud backups of photos: more is better; 20 Mbps or more makes a real difference.
- Working from home with large files: fibre plans with matching upload speeds are worth it.
Cable plans often have upload speeds a tenth of the download speed. Fibre usually offers equal or much higher upload. The upload gap is the surprise most people notice first.
When a faster plan won’t help
Upgrading your plan only helps if the plan is the bottleneck. It won’t help if:
- Your WiFi is weak in the rooms where you use it most.
- Your router is old and can’t deliver the speed over WiFi.
- Devices are old and only support WiFi 4 or 5.
- The problem is lag in games, which depends more on ping than speed.
Test with a cable next to the router. If you get close to your plan speed there, fix your WiFi before paying for a faster plan. The cable test is the one that saves people from a needless upgrade.
Speed per person, roughly
A simple rule of thumb many people use is about 25 to 50 Mbps per person who streams or works online at the same time, plus a bit extra for downloads and smart devices.
- 1 to 2 people: 50 to 100 Mbps.
- 3 to 4 people: 100 to 300 Mbps.
- 5+ people or heavy users: 300 Mbps to 1 Gbps.
It’s only a starting point. A gamer who downloads 100 GB updates or someone uploading video for work will want more than the average. Heavy users are the ones I nudge above the rough guide.
Check what you use now
- Look at your router app’s traffic or usage page, if it has one.
- Run a speed test at your busiest time of day.
- Note whether things slow down when several people are online.
- If speed tests are close to your plan but things feel slow, upgrade WiFi first. If tests are low, talk to your ISP.
The busy-hour test is the one that tells me the truth about a plan.
Latency matters for some activities
For gaming, video calls and remote desktop work, a stable, low-latency connection matters more than raw speed. Fibre and cable usually have low latency; satellite and some fixed wireless services have higher latency. If you work on calls all day, ask providers about typical latency as well as speed before signing up.
For calls all day, I ask about latency before I ask about speed.
