What Uses the Most Internet Data? (2026 Guide)
If you have a data cap or want to understand your usage, here's roughly what common activities consume.
Video streaming (the biggest)
SD video ~1 GB/hour, HD ~3 GB/hour, 4K ~7 GB/hour. Streaming is by far the largest data user in most homes.
Video calls
Group HD calls use ~1–2 GB/hour. Audio-only is a fraction of that.
Online gaming
Surprisingly light — most games use ~40–150 MB/hour. The big cost is downloading games and updates, which can be 50–100+ GB each.
Music streaming
~50–150 MB/hour depending on quality — modest.
Browsing and social media
Light text browsing is tiny, but autoplay video on social feeds adds up quickly — often more than people expect.
Estimate your needs
Add up your household's typical hours. Heavy 4K + gaming homes can use 1 TB/month or more. If your speed feels slow despite low usage, run our test — the problem is usually speed or bufferbloat, not your data total.
