When it comes to streaming movies and TV shows, there are a lot of factors that can affect how much data you use. The quality of your stream, the length of the movie or show, and even the type of device you’re using can all play a role.

In general, you can expect to use between 1 and 3 gigabytes (GB) per hour of streaming video. That means if you want to watch a two-hour movie, you’ll need between 2 and 6 GB of data.

Of course, this is just a general estimate. If you’re watching in HD or 4K, you’ll use more data. And if you’re watching on a phone or tablet, you’ll use less data than if you’re watching on a TV or computer.

If you’re not sure how much data you have to work with, most streaming services have an option to let you choose the quality of your stream. For example, Netflix has options for “Low,” “Medium,” and “High” quality streams. Choosing a lower quality stream will use less data.

Ultimately, it’s up to you to decide how much data you’re comfortable using. If you want to be extra careful, keep an eye on your usage while streaming and stop when you reach your limit.

How much data does streaming a movie use?

How much data you use when you stream a movie depends on the quality of video you want to watch. For example, watching a movie in standard definition will use up to 0.7GB per hour, while HD video can go up to 3GB per hour.

How many gigabytes does watching a movie use?

It depends on the movie file size and your internet connection speed. A two-hour movie at standard definition requires about 2.4GB of data, while a high-definition movie needs about 4.5GB. If you’re watching a streaming service like Netflix, Hulu, or Amazon Instant Video, the company will automatically adjust the quality based on your internet connection to avoid interruptions.

What factors affect movie streaming data usage?

There are a few factors that affect how much data you use when streaming a movie. The biggest factor is the quality of the video. If you’re streaming in HD, you’ll use more data than if you’re streaming in standard definition. The other factor is the length of the movie. Obviously, a two-hour movie is going to use more data than a 30-minute show.

How to reduce the amount of data used when streaming movies

According to Netflix, watching movies or TV shows on their platform uses about 1 GB of data per hour for standard definition (SD) quality. For high definition (HD) quality, you will use up to 3 GB of data per hour. If you are watching a Ultra HD 4K movie or show, you will use up to 7 GB of data per hour.


In conclusion, watching a movie on Netflix requires about 3 GB of data per hour for standard definition quality, and 7 GB per hour for high definition quality. Therefore, if you have a limited amount of data to use each month, it’s best to either watch movies in standard definition or be selective about the movies you watch.
