How Much Data Does Streaming Use? (Per Hour)
How much data does streaming use per hour? Netflix, YouTube, Disney+, Spotify, Twitch and Zoom in SD, HD and 4K, plus how to cut data use on a Windows PC.

Video streaming uses about 1 GB per hour in SD, 3 GB per hour in HD (1080p) and 7 GB per hour in 4K on Netflix; YouTube and other services are similar. Music streaming uses far less: 40–150 MB per hour. A video call uses roughly 0.5–2.5 GB per hour. On a 100 GB monthly cap, that is about 33 hours of HD video or 14 hours of 4K.
You are on a mobile hotspot, a capped home plan or hotel Wi-Fi, and you want to watch a film without blowing your data. The answer to how much data does streaming use depends mostly on video quality, much more than on the service. This guide gives per-hour figures for the most popular apps, a quick calculator table, and practical ways to cut usage on a Windows PC.
Video Streaming Data Per Hour
| Service | Low / SD | HD 1080p | 4K UHD |
|---|---|---|---|
| Netflix | 0.3–1 GB | up to 3 GB | up to 7 GB |
| YouTube | 0.3–0.7 GB (480p) | 1.5–3 GB | 7–15 GB |
| Disney+ | about 0.7 GB | about 2–3 GB | about 7.7 GB |
| Amazon Prime Video | about 0.4–0.8 GB | about 2–3 GB | about 6–7 GB |
| Twitch (live) | about 0.3–0.6 GB | 2.5–3.5 GB (1080p60) | — |
Figures are approximate; services adjust bitrate to your connection, and action-heavy content uses more than a talk show. 60 fps streams use about 50% more than 30 fps at the same resolution. Services' "Auto" setting picks the highest quality your connection allows, which on fast internet usually means the most data.
Music, Podcasts and Video Calls
| Activity | Data per hour |
|---|---|
| Spotify / Apple Music (normal) | 40–70 MB |
| Spotify very high (320 kbps) | about 145 MB |
| Lossless / hi-res music | 0.6–1.5 GB+ |
| Podcasts | 30–60 MB |
| Zoom / Teams / Meet, 1:1 HD | 0.5–1.2 GB |
| Group video call, gallery view HD | 1–2.5 GB |
| Voice-only call | 30–60 MB |
How Far Does Your Data Go?
| Allowance | SD (1 GB/h) | HD (3 GB/h) | 4K (7 GB/h) |
|---|---|---|---|
| 10 GB | 10 h | 3 h | 1.5 h |
| 50 GB | 50 h | 16 h | 7 h |
| 100 GB | 100 h | 33 h | 14 h |
| 1 TB | 1,000 h | 333 h | 143 h |
To convert bitrate to data: Mbps × 0.45 = GB per hour. A 5 Mbps stream uses about 2.25 GB per hour. Why bits and bytes differ is explained in our internet speed guide.
How to Use Less Data When Streaming
-
Set quality manually
On YouTube pick 720p or 480p in the gear menu. In Netflix's account settings choose Data usage per screen: Low or Medium. On a laptop screen, 720p looks fine and uses about half the data of 1080p.
-
Download at home first
Netflix, Disney+, Prime Video and Spotify let you download on unlimited Wi-Fi and watch offline later.
-
Mark the connection as metered in Windows
On a hotspot or capped plan, Windows can pause updates and background sync. See how to set a metered connection on Windows 11.
-
Turn off autoplay and video in calls
Autoplay previews and the next episode quietly add up. In calls, turning your camera off cuts usage by more than half.
-
Track usage as you go
Windows shows usage per app in Settings > Network & internet > Data usage. For a live view and an alert before you hit your cap, use a data meter.
Track Your Streaming Data on Windows
DU Net Meter shows your live speed in a small always-on-top widget, records daily usage and tracks a data plan with a monthly limit, so you see how much a film actually used and how much allowance is left. The built-in Windows method is covered in check data usage on Windows 11.
How Much Data Does Streaming Use for a Household?
Monthly usage adds up quickly when several people stream. Rough examples at HD quality:
| Household habit | Per month |
|---|---|
| 1 person, 1 hour of HD video a day | about 90 GB |
| 2 people, 2 hours of HD a day each | about 360 GB |
| Family, 4K TV 3 hours a day plus phones | 700 GB – 1 TB |
| Music only, 2 hours a day | 3–9 GB |
Games add their own downloads: a single large game update can be 20–100 GB, often more than a month of video for one person.
FAQ
How much data does a 2-hour movie use?
About 2 GB in SD, 6 GB in HD and 14 GB in 4K on Netflix-like bitrates.
Does streaming use more data on a TV than a phone?
Usually yes. TVs request higher resolution by default. Phones on mobile data often use a data-saver mode automatically.
Does pausing a stream stop data use?
Mostly. The player may keep buffering for a short while, then it stops.
Is 100 GB a month enough for streaming?
For one person watching about an hour of HD a day, roughly. Households that stream in 4K need several hundred GB or an unlimited plan.
Conclusion
Streaming uses about 1 GB per hour in SD, 3 GB in HD and 7 GB in 4K, while music uses a tiny fraction. Choose quality manually, download before you travel, and track usage so your cap holds until the end of the month. Explore more network apps for Windows.
