How do I know how many GB of data I need?

With the rise of streaming, social media, and working from home, many wonder just how much data they really need. Choosing the right data plan can be tricky with so many options available. Here are some quick answers to common questions about data usage:

How much data does streaming video use? Streaming high definition video can use 3GB per hour. Standard definition uses closer to 1GB per hour.

How much data do social media apps use? Social media apps like Facebook and Instagram use very little data, generally less than 100MB per hour.

How much data does web browsing and email use? Light web browsing and email generally uses less than 250MB per hour.

How much data do online games use? Online gaming uses between 100MB-250MB per hour depending on the game.

Estimating Your Monthly Data Needs

When estimating how much data you need each month, consider these common data usage factors:

  • Streaming video – High definition streaming can use 3GB or more per hour. Estimate how many hours per week you stream videos.
  • Social media apps – These use less than 100MB per hour. Time spent can add up.
  • Web browsing and email – Light use is less than 250MB per hour.
  • Online gaming – Most games use 100MB-250MB per hour.
  • Audio streaming – Music streaming uses about 60MB per hour.
  • Operating system and security updates – Can use up to 500MB per month.
  • Smart home devices – Security cameras and smart assistants use about 200MB per month each.

Add up your expected weekly usage for each activity and multiply by 4 to estimate your monthly needs. An additional 10-20% buffer is also recommended.

Data Usage for Light, Moderate, and Heavy Users

Here are some typical monthly data needs for light, moderate, and heavy data users:

User Type Typical Monthly Use
Light User 2-4GB
Moderate User 4-8GB
Heavy User 8-16GB

Light users who mainly use email, web browsing, and social media can often get by with 2-4GB per month. Moderate users who stream video a few hours a week and game online will need 4-8GB. Heavy users who stream high definition video daily will want 8GB or more.

Comparing Data Plans

Once you estimate your monthly needs, you can compare mobile and home internet data plans. Here are some key factors to consider:

  • Data allowance – Compare plans to your estimated monthly needs.
  • Overage charges – Plans charge if you exceed the data allowance.
  • Throttling – Speeds may be slowed if you exceed the data cap.
  • Hotspot allowance – For using mobile data on other devices.
  • Video resolution – Some plans limit streaming resolution.
  • 5G access – Provides faster speeds when available.

Prioritize plans that offer at least 10-20% buffer over your estimated usage to avoid overages. Also consider needs for hotspot usage and video streaming quality.

Saving on Data Usage

If you want to minimize data usage, here are some tips:

  • Use WiFi whenever available – Saves mobile data usage.
  • Download content for offline use – Such as playlists, videos, podcasts.
  • Reduce streaming resolution – Standard definition uses less data.
  • Disable auto-play on videos.
  • Close unused browser tabs and apps.
  • Turn off background app refresh.
  • Disable iOS and Android OS updates over cellular.

Enabling WiFi assists like WiFi assist and Adaptive WiFi calling can also help reduce usage by automatically using WiFi data instead of cellular when available.

Tracking and Monitoring Usage

You can monitor your data usage to make sure you stay within your plan’s limits using these steps:

  • Turn on data usage tracking in your device settings.
  • Set data usage warnings and limits.
  • Check usage in account settings for your carrier.
  • Use carrier and third party apps to monitor usage.
  • Be aware of usage early in billing cycle.

Data tracking through your operating system or carrier is the most accurate way to monitor usage. This allows you to see which apps are using the most data so you can adjust as needed.

Choosing Unlimited Data

Unlimited data plans are also available from most carriers. You may consider upgrading to unlimited data if:

  • You consistently exceed data caps each month.
  • You want to stream high resolution video without limits.
  • You want to use mobile hotspots without worrying about data.
  • You have multiple family members on one plan.

Unlimited plans provide the most flexibility and value for heavy data users. However, they are more expensive than tiered data plans. Carefully calculate your needs before choosing an unlimited option.


Choosing the right data plan requires estimating your usage across streaming, browsing, gaming, and other activities. Compare plan allowances and features to your needs. Monitor usage to avoid overages. Light users can get by with 2-4GB per month, while heavy video streamers need 8GB or more. Carefully calculating your needs will ensure you choose the optimal data plan.
