How Much Data Does Streaming Use? Netflix and YouTube Per Hour (2026)
How much data does streaming use? If you watch on a mobile package, knowing how much each hour of video uses helps you choose the right bundle and avoid running out. The main factor is video quality.
You can control quality in your account settings; see Netflix’s official guide to data usage.

Key takeaways
- How much data streaming uses depends mainly on video quality, not the app.
- On Netflix, the answer to how much data does streaming use is about 1 GB per hour in SD and up to 3 GB in HD.
- 4K can use up to 7 GB per hour, so it is best kept for unlimited Wi-Fi.
- Data-saver modes can give you several hours of video per gigabyte.
- Long live sports streams use more data than most people expect.
Netflix data use per hour
- Low quality: about 0.3 GB
- Standard definition (SD): about 1 GB
- High definition (HD): up to 3 GB
- Ultra HD (4K): up to 7 GB
On a phone, Netflix’s “Save Data” setting gives roughly six hours of viewing per gigabyte.
YouTube and other apps
YouTube, Tamasha and other apps use similar amounts at the same resolution. A 480p stream uses a fraction of a 1080p stream, and on a small phone screen the difference is hard to see.
How long will my bundle last?
- 5 GB bundle: about 5 hours of SD, or under 2 hours of HD
- 25 GB bundle: about 25 hours of SD, or 8 hours of HD
These are estimates: actual use depends on the app, the content and your connection.
How to use less data
- Set video quality to 480p or “Data saver” in each app.
- Download episodes on Wi-Fi for offline viewing.
- Turn off autoplay and video previews.
- Use your network’s streaming bundle where available.

Streaming data use at a glance
So, how much data does streaming use at each quality level? Here is a simple way to think about it. Every step up in quality roughly doubles or triples the data used per hour:
- Phone, data saver: about 0.2–0.3 GB per hour
- Phone or tablet, normal quality: about 0.7–1 GB per hour
- Laptop or TV in HD: about 3 GB per hour
- Large TV in 4K: up to 7 GB per hour
Live TV and sports
Live streams on apps such as Tamasha and Tapmad work the same way: the higher the quality, the more data they use. Because sports matches are long, a single cricket match in HD can use more data than several episodes of a drama. Lower the quality for live sport if you are on a limited bundle.
Music and audio streaming
How much data does streaming use for music? Far less than video. An hour of music streaming typically uses well under 0.2 GB, so it is rarely the reason a bundle runs out. If your data is disappearing fast, video is almost always the cause.
Watch out for hidden data use
- Autoplay starting the next episode while you are not watching
- Background app updates over mobile data
- Video ads in unofficial apps, which can play even when you are not using the app
- Hotspot sharing, where another device streams in HD on your connection
Fixing these can save as much data as lowering the video quality.
Frequently asked questions

On Netflix, HD streaming can use up to 3 GB per hour. Standard definition uses about 1 GB per hour.
Does YouTube use less data than Netflix?
At the same resolution they use similar amounts. Lowering the quality in either app saves the most data.
How can I check my data use?
Open your phone’s Settings and look for Data usage, or check your remaining balance in your network’s app.
Final thoughts
Now that you know how much data does streaming use at each quality, a few settings changes can make your monthly bundle last far longer.
