How Much Data Does YouTube Use?
YouTube's burn rate is set by the resolution you watch at — and its auto quality happily climbs when bandwidth allows. Here are the per-hour figures and the calculator for your monthly total.
Short answer
At 480p YouTube uses about 0.7 GB per hour; 1080p runs roughly 1.5–3 GB per hour depending on the video's bitrate, and 4K can reach 7 GB per hour. An hour a day at 1080p is up to ~90 GB a month. Set a fixed quality in the player to keep auto mode from silently upgrading you to a higher tier.
Hours per day, on a typical day:

About the numbers
Shorts and autoplaying feeds add up faster than they feel — short vertical video is still video. On mobile, YouTube's data-saver mode caps streams at a lower resolution, which is the single most effective switch if you are on a small allowance.
Data used per hour by activity
| Activity | GB per hour | Per month at 1 h/day |
|---|---|---|
| Web browsing & email | 0.1 GB | 3 GB |
| Social media & short video | 0.2 GB | 6 GB |
| Music streaming | 0.1 GB | 3 GB |
| SD video streaming (480p) | 0.7 GB | 21 GB |
| HD video streaming (1080p) | 3 GB | 90 GB |
| 4K video streaming | 7 GB | 210 GB |
| HD video calls (Zoom, Meet) | 1 GB | 30 GB |
| Online gaming (play, not downloads) | 0.1 GB | 3 GB |
Published service figures (Netflix, YouTube, Zoom) — adaptive streaming means real rates flex with your connection and quality settings.
What common data caps cover
| Data cap | Hours of hd video streaming (1080p) | Hours of music streaming | Hours of social media & short video |
|---|---|---|---|
| 5 GB | 1 | 50 | 25 |
| 10 GB | 3 | 100 | 50 |
| 15 GB | 5 | 150 | 75 |
| 20 GB | 6 | 200 | 100 |
| 30 GB | 10 | 300 | 150 |
| 50 GB | 16 | 500 | 250 |
| 100 GB | 33 | 1,000 | 500 |
| 300 GB | 100 | 3,000 | 1,500 |
Each column assumes the cap is spent on that activity alone: hours = cap ÷ GB per hour. Mixed use splits the cap.
How we calculate this
Straightforward multiplication, with the per-hour rates doing the real work:
- Daily usage. each activity's GB-per-hour rate × your daily hours, summed across everything you do in a typical day.
- Monthly total. daily GB × 30 days — the planning convention ISPs use for a billing month.
- Cap coverage. your cap ÷ daily GB gives the days it lasts; cap ÷ a single activity's rate gives the hours of that activity it covers.
Assumptions
- Per-hour rates are published service figures (Netflix and YouTube quality tiers, Zoom bandwidth) — adaptive streaming varies the real rate with your connection.
- Data amounts use decimal units (1 GB = 1,000 MB), matching how ISPs meter caps.
- Game-install and system-update downloads are one-off transfers on top of the hourly figures — a single 100 GB install outweighs months of online play.
- A billing month is counted as 30 days.

Frequently asked questions
How much data do I use in a month?+
Multiply each habit's hourly rate by your daily hours, then by 30: HD streaming uses about 3 GB an hour, 4K about 7 GB, SD about 0.7 GB, video calls about 1 GB, music around 0.1 GB, and online gaming only ~0.1 GB. Two hours of HD video a night is already ~180 GB a month, which is why streaming quality — not time online — decides most people's total. The calculator adds your whole mix up for you.
How much data does streaming video use?+
It scales with picture quality: roughly 0.7 GB per hour in SD (480p), up to 3 GB per hour in HD (1080p), and up to 7 GB per hour in 4K. The same show can therefore use ten times more data on a 4K TV than on a phone in data-saver mode. Every major service (Netflix, YouTube, Disney+) has a quality setting that caps this.
Is 100 GB of data enough for a month?+
100 GB covers about 33 hours of HD streaming, or 140+ hours of SD, or 1,000 hours of music — so it is comfortable for phone-first use with moderate video, but tight as a household's only connection. If you run a TV on it, drop the stream quality to SD; if it's a hotspot for work calls and browsing, 100 GB usually lasts the month easily.
Does online gaming use a lot of data?+
Playing uses surprisingly little — around 100 MB (0.1 GB) per hour, so even a 30-hour month of matches is ~3 GB. What empties caps is everything around the game: installs of 50–150 GB, patches of 20+ GB, and cloud gaming, which streams like HD/4K video at gigabytes per hour. On a capped plan, download games on unmetered WiFi and play natively rather than via cloud streaming.
How can I use less data without giving anything up?+
Three settings do most of the work: cap streaming quality (HD instead of 4K cuts video data by more than half; SD cuts it by ~75%), turn on data-saver modes in YouTube, Spotify and your phone's OS, and move game installs, cloud backups and system updates to unmetered WiFi. Autoplaying feeds are the silent extra — disabling video autoplay in social apps trims a habit you never chose.
Why does my phone report different usage than my carrier?+
Carriers meter every byte that crosses their network — including carrier services, tethered devices, and overhead your phone's own counter attributes differently — and their billing cycle rarely lines up with your phone's counting period. Treat the carrier's number as the billable truth, reset your phone's counter to the billing date, and leave a 10–15% margin between your estimate and the cap.
