What broadband speed do I need by household size?
You need enough capacity for the busiest overlapping moment, not a census count. Four quiet retirees use less aggregate bandwidth than two remote workers with toddlers streaming CBeebies - headcount is a weak proxy without behaviour.
Examples by people and behaviour
| 1 person | Light browsing and SD streaming: modest Mbps. Add 4K, cloud creative work, or big game patches and the picture changes. |
|---|---|
| 2 people | Think “do both work calls overlap?” A couple in York with staggered meetings stresses the line less than simultaneous Teams plus a 4K film. |
| 4 people | School-night pattern: homework tablets, parent VPN, console update, and iPlayer - plan for that stack, not four divided-by-maths Mbps. |
| 5+ people | Shared houses and multi-generational homes: peak contention is real; Ethernet to the busiest desk often matters as much as tier. |
Scenario: two adults, one child
In Liverpool, Mum hosts Zoom while Dad pulls a PS5 update and the child watches YouTube Kids on a tablet. The “right” speed is whatever keeps that triangle from stalling - Pulse at 6 p.m. tells you more than dividing package tiers by three.
Scenario: five flatmates
A Brighton HMO spikes at 10 p.m. when everyone is online. Individual speed tests from phones in bedrooms looked “fine” in isolation; simultaneous use exposed the real pinch.
What to try first
- Sketch your worst hour and list devices active then.
- Run Pulse during that hour from the hardest-working room.
- If Wi-Fi is the limit, fix placement before buying a bigger tier.
How Pulse relates to this topic
Pulse helps quantify what the line delivers when your household actually loads it - download, latency, and jitter without storing results server-side. It cannot model every device’s appetite, but it grounds guesses in numbers.

FAQ
Do more people always need more Mbps?
Only if they are online at the same time doing heavy tasks. Three people reading email is different from three 4K streams.
How do I count simultaneous activity?
Picture your busiest hour: homework downloads, work VPN, gaming, and TV - add those demands, not bedrooms.
Is a large house automatically heavier on broadband?
Not by square footage alone. Wi-Fi coverage can matter more than Mbps if rooms far from the router struggle.
Should lodgers or guests change my package?
If they add overlapping peak-time use, yes. Occasional visitors rarely move the needle.
