How many GB per month do I need internet?

With the rise of streaming services, video calls, online gaming, and more data-heavy internet use, many wonder just how much internet data they really need each month. The amount of gigabytes (GB) per month you need depends on your household size, number of devices, types of online activities, and more. This comprehensive guide examines how different factors impact your data needs and provides tips for getting the right data plan.

How Much Data Do Typical Online Activities Use?

First, it helps to understand how much data common online activities usually consume. Here are estimates for data usage per hour of some popular internet activities:

Activity Data Usage per Hour
SD Video Streaming 1 – 3 GB
HD Video Streaming 3 – 7 GB
4K Streaming 7 – 15 GB
Online Gaming 1 – 4 GB
Video Calls 1 – 3 GB
Social Media Use 0.1 – 0.3 GB
Web Browsing 0.3 – 0.8 GB

As you can see, video streaming is one of the biggest data drains. SD video isn’t too bad, but streaming in HD or 4K quality can quickly eat through data caps. Online gaming also requires a constant internet connection and uses 1 GB or more per hour. In comparison, lighter online activities like social media and web browsing use less than 1 GB per hour.

Factors That Impact Your Data Needs

Several key factors determine how much monthly data your household really requires:

Household Size

The number of people in your home using the internet connection is a major factor influencing data needs. More people means more devices streaming, gaming, surfing the web simultaneously.

Here are some estimates for data needs based on household size:

  • 1 person household – 50 to 200 GB per month
  • 2 person household – 100 to 300 GB per month
  • 3 person household – 150 to 500 GB per month
  • 4+ person household – 200 to 700+ GB per month

Number of Connected Devices

In addition to the number of people, the number of connected devices like laptops, tablets, smartphones, gaming consoles, and smart home gadgets also impacts data usage. More devices means more data streaming and downloading even if household members aren’t actively using all the devices simultaneously.

Types of Usage

Data needs also depend on how each person uses the internet connection:

  • Light usage: Email, web browsing, social media, occasional video streaming. 25 GB per person minimum.
  • Moderate usage: Streaming HD video for 1-2 hours daily, light gaming, active on social media. 50 GB per person minimum.
  • Heavy usage: Streaming HD/4K video and cloud gaming for 3+ hours daily, video calls, high social media use. 100+ GB per person minimum.

Connectivity Type

Your type of internet connectivity also determines speed and data capacity:

  • Mobile data – Typically lowest speeds and data caps around 5-50 GB per month before throttling.
  • DSL – Provides 5-100 Mbps speeds and 150-1000 GB monthly data caps on average.
  • Cable – Delivers 25-500 Mbps speeds with 300-2000 GB monthly data caps.
  • Fiber – Offers 50-2000+ Mbps speeds and unlimited data or very high caps of 1000 GB and beyond.

Fiber internet can support basically unlimited high-quality video streaming and downloads with 1000+ GB monthly caps or no caps at all. Mobile data and DSL have much lower speeds and caps that can constrain data usage.

Tips for Getting the Right Data Plan

Use these tips to find the optimal internet data plan for your household:

Track your current usage

Monitor your monthly data usage for 2-3 months to understand your household’s needs before shopping for a new plan.

Allow for growth

Add at least 20-50% more data to your current tracked usage to account for future increases in usage.

Consider peak usage

Look at individual monthly peaks not just the average. Account for seasons like summer when kids are home streaming more.

Pick unlimited if you can

If fiber gigabit plans with unlimited data are available in your area, this is generally the best future-proof option.

Bundle services

Bundling internet, TV, and phone can help you save money each month on your overall bill.

Watch for deals

ISPs frequently offer deals for new subscribers. Taking advantage can lower your monthly costs.

Avoid contracts

Month-to-month plans cost more but provide flexibility to change plans as your needs evolve.

Data Needs for Light, Moderate and Heavy Usage

Here are some more specific estimates for data needs based on light, moderate or heavy internet usage profiles:

Light Usage Household

  • Email
  • Social media
  • Web browsing
  • Occasional video streaming
  • 1-3 devices connected

Minimum data needed: 100 GB per month

Moderate Usage Household

  • Work video calls
  • HD video streaming 1-2 hours daily
  • Light online gaming
  • Active on social media
  • 4-6 devices connected

Minimum data needed: 300 GB per month

Heavy Usage Household

  • HD and 4K video streaming 3+ hours daily
  • Online cloud gaming
  • Video calls
  • High social media use
  • Smart home devices
  • 6-10 devices connected

Minimum data needed: 500+ GB per month

Data Usage for Streaming Video

Video streaming is one of the biggest data hogs. Here’s a closer look at how streaming video quality and duration impacts data consumption:

Video Streaming Data Usage Per Hour

  • SD quality: 1 – 3 GB per hour
  • HD quality: 3 – 7 GB per hour
  • 4K quality: 7 – 15 GB per hour

Data for Streaming 1 Movie

  • SD movie (2 hours): 2 – 6 GB
  • HD movie (2 hours): 6 – 14 GB
  • 4K movie (2 hours): 14 – 30 GB

Data for Streaming Video Daily

  • 1 hour SD video daily: 30 – 90 GB monthly
  • 1 hour HD video daily: 90 – 210 GB monthly
  • 1 hour 4K video daily: 210 – 450 GB monthly

From this projection, you can calculate the increased data needed for multiple hours of streaming per day at each resolution.

Data Usage for Online Gaming

Online gaming also consumes significant data. Here’s a look at how many GB you can expect to use per hour and month:

  • Online gaming data per hour: 1 – 4 GB
  • Online gaming daily for 1 hour: 30 – 120 GB monthly
  • Online gaming daily for 2 hours: 60 -240 GB monthly
  • Online gaming daily for 4 hours: 120 – 480 GB monthly

These estimates are for multiplayer online gaming like MMORPGs, MOBAs, first-person shooters, and battle arena games. Single player offline gaming uses minimal data.

Data Usage for Smart Home Devices

Smart home gadgets like virtual assistants, security cameras, video doorbells, and smart thermostats also add to your data requirements. Here are some typical data consumption estimates:

  • Smart speaker: 1 – 5 GB per month
  • Smart camera: 60 – 150 GB per month
  • Video doorbell: 50 – 200 GB per month
  • Smart thermostat: 0.5 – 2 GB per month

These numbers can vary based on video quality settings and frequency of use. Having 3-5 smart home devices could add 100+ GB of monthly data usage in a household.
