Netflix popularized binge viewing. But some of its shows are more binge-able than others.

The streaming service, which does not release viewership data for its programming, on Tuesday offered a bit of information about how much time viewers spend watching its original series and other shows available on its service.

Netflix measured the amount of time that users spent watching more than 100 different titles. The median viewing time for a Netflix user watching one title was two hours and 10 minutes per sitting, the company found, with the median time for completing a series standing at six days. It then divided its titles up into two categories — “savored” and “devoured.”

Titles in the “devoured” camp included “Sense8,” “Orphan Black,” “The 100,” “The Walking Dead,” “American Horror Story,” “The Fall,” “Orange Is the New Black,” “Nurse Jackie,” “Hemlock Grove,” “Marco Polo,” “Breaking Bad” and “Grace & Frankie.” Those were typically completed in four days and viewed roughly two hours, 30 minutes per sitting.

On the “savored” side are “House of Cards,” “Bloodline,” “Peaky Blinders,” “Narcos,” “Daredevil,” “Mad Men,” “BoJack Horseman,” “Love” and “Unbreakable Kimmy Schmidt.” Those titles are typically completed in six days and viewed roughly one hour and 45 minutes per sitting.

Netflix analyzed viewing data from more than 190 countries from October 2015 to May 2016 for the survey.

Here’s the Netflix “binge scale.”
