How to Use the Streaming Data Usage Calculator
Enter your average daily viewing hours, the number of days you stream per month, and the quality you typically watch at to estimate your data usage for Netflix, YouTube, Disney+, and other streaming services. Useful for choosing a mobile data plan.
Data Usage by Video Quality
Typically, low quality (SD) uses about 0.7GB per hour, standard HD (720p) about 1.5GB, Full HD (1080p) about 3GB, and 4K ultra HD about 7GB. Actual figures vary slightly by service and compression method.
When Your Data Plan Isn't Enough
Most streaming apps let you manually lower quality in their settings. Dropping from 4K to HD alone can cut data usage by more than half, and setting high quality to auto-enable only on Wi-Fi is another effective way to save mobile data.
Frequently Asked Questions
Watching in HD instead of 4K cuts hourly data usage to roughly a fifth. If your mobile data plan is limited, lowering quality in the app settings is the most reliable way to save data.
Most home Wi-Fi plans are unlimited, so data caps aren't usually a concern. But if your connection speed is slow, high-quality streaming can cause buffering — lowering quality helps reduce interruptions.
