One great thing about Netflix is that no matter which plan you choose, you get the same awesome content—over 200 movies, TV reruns, and Netflix Originals. We think that’s pretty sweet.

So why pay for the more expensive packages? It all comes down to the streaming quantity and quality.

See, Netflix’s Basic package gets you only one stream, while the Standard package upgrades you to two. That means with the Basic service, only one person can watch at a time. Sounds a little more like the start of a battle royale than a relaxing night of your favorite shows.

If the idea of sharing even two streams makes you start to sweat, you might snag the Premium package. For only three dollars more, you’ll double your available streams. And with four simultaneous streams, you should be able to watch whatever you want without seeing the dreaded “You’ve reached your limit” screen. Score!

While the streams are a key part of the differences, it’s worth noting that the different packages also get you different tiers of video quality. We’ll explain more later, but basically, the higher the package, the better the video quality.
