How to classify Android Devices based on DPI values?

Question

In Android, various devices are classified into different categories based on their density.

LDPI = 120 DPI
MDPI = 160 DPI
HDPI = 240 DPI
XHDPI = 320 DPI
XXHDPI = 480 DPI
XXXHDPI = 640DPI

Here my doubt is, if an Android device has density as "200 DPI", will it falls under which of the above category? (example: Nexus 5 have 217dpi,whether it'll come under HDPI or MDPI).

Can anyone say, what is the exact range for different densities(LDPI,MDPI,XXHDPI.....).

Answer 1

It's not one density but rather ranges (often called "buckets"). This is documented here and this picture I post below should explain how to classify it correctly (it lacks xxhdpi and xxxhdpi though, but the rule is the same)
