What Broadband Speed Does Your Household Need?
The honest answer is rarely the highest number a provider advertises. It is whatever comfortably covers everything your household actually does online at the same time, which is a household specific question, not a national one.
Start from what happens at the same time, not one activity at a time
A single person streaming video alone in a house does not need the same connection as a house with four people simultaneously on a video call, streaming in another room and running a games console at the same time. Our main guide to broadband in Ireland lists the factors that shape the right plan for a household. This article works through how to actually reason about them against your own household, rather than treating them as a second list to tick off.
The single biggest driver of how much speed you need is not any one activity, it is how many of those activities happen at the same time, in the same house, sharing the same connection. Count devices, not people: a household of two adults can easily have five or six devices connected at once between phones, laptops, a smart TV and a games console, even if only two people are actively using the connection. Then find your household's peak hour, not its average hour, since a connection is rarely stressed by its quietest moment. Think about the busiest point in a typical evening, when the most people and devices are active together, since that is the moment a connection actually needs to cope with, not a rough daily average.
Download speed covers most everyday activities, but not the whole picture
Download speed, the figure most heavily advertised, covers browsing, streaming and downloading files, and is genuinely the more important figure for most households most of the time. But it is not the only figure that matters. Upload speed, which covers sending data from your home outward, such as a video call, backing up photos to the cloud, or uploading a large file for work, is often advertised as a much smaller figure than download speed, particularly on connection types where the two are not evenly matched. If anyone in the household works from home with video calls, or regularly uploads large files, ask specifically for the upload figure rather than assuming it scales with the download number.
Indicative speeds, and why they are only a starting point
The figures below are indicative download speeds for common uses, drawn from what services such as Netflix and Microsoft Teams publish. Treat them as a starting point rather than a requirement. Services periodically change their recommendations, and what your household actually needs depends on how many of these activities happen at the same time and on the quality and stability of the connection, not just its headline speed. For a service you rely on, check its own current help pages.
| Use | Indicative speed |
|---|---|
| Light browsing, email and social media | A few Mbps per device |
| HD video streaming | Around 5 Mbps per stream |
| 4K video streaming | Around 15 to 25 Mbps per stream, depending on the service |
| Video calls and working from home | Around 2.5 to 4 Mbps per call, with upload mattering as much as download |
| Online gaming | Modest speed while playing, where low latency matters more; large game downloads and updates benefit from much faster speeds |
| Several people online at once | Add together everything that happens at the same time, then allow headroom |
| Larger or busier households | Two 4K streams and two video calls at once add up to roughly 35 to 60 Mbps of download on the figures above, before any headroom |
Online gaming and video calls are sensitive to latency, meaning how quickly data travels back and forth, and to connection stability, not only to how much data can flow per second. A connection with a high headline download speed but poor stability can still perform badly for a video call or a competitive game, while a comparatively modest connection with low latency and few interruptions can perform well. If gaming or calls are a daily priority, ask providers about latency and stability specifically, not only about the top line speed.

Working from home changes the calculation, not just the number
A household with regular video calls during working hours needs a connection that stays stable and responsive throughout the working day, not just a high number on a spec sheet. This is one of the more common reasons a household outgrows a plan that looked perfectly adequate when it was chosen for personal use alone, since working-from-home calls introduce a steady daytime demand that a household's previous, evening-only usage pattern never tested. If working from home is a fixture rather than occasional, it is worth treating it as its own line item when you compare plans, alongside asking specifically about upload speed and connection stability during the day.
Why an actual speed test still matters more than an advertised figure
An advertised speed describes what a connection type can typically deliver, not a guarantee for your specific line or router setup. Once you have a connection installed, a wired speed test, run with a cable directly into the router rather than over WiFi, gives the most accurate picture of what your plan is actually delivering. If a wired test consistently falls well short of what was advertised, that is a conversation to have directly with your provider, separate from the question of whether your WiFi coverage around the home is the real source of a slow-feeling connection in a particular room, which our guide to broadband in Ireland covers under speed versus WiFi performance.
Working out your household's speed needs
- Count how many devices are realistically active at your household's busiest time of day, not just how many people live there
- Identify anyone who works from home with regular video calls, and treat that as a separate requirement
- Flag online gaming as a latency and stability question, not only a speed question
- Note any regular upload heavy activity, such as cloud backups or large file transfers
- Check the current recommended speed directly from any streaming or call service you actually use, rather than a fixed number from an unrelated guide
- Once connected, run a wired speed test to check what you are actually getting against what was advertised
Once you know roughly what your household needs, the next question is which connection type can actually deliver it at your address.
