Determining Android Screensize based on Resolution

What are the criteria for a tablet device to fall under largescreens or xlargescreens?

I was looking at the Android dev guide and there is a clear definition for smallScreens and normalScreens, but the documentation is a bit vague regarding largescreens and xlargescreens.

smallScreens HVGA resolution

normalScreens HVGA with medium density WQVGA with low density WVGA with high density

largeScreens A large screen is defined as a screen that is significantly larger than a "normal" handset screen.

xlargeScreens An xlarge screen is defined as a screen that is significantly larger than a "large" screen.

Is there a resolution cut-off for largescreens? For example anything higher than or WSVGA (1024 × 600), and XGA (1024 × 768) is considered xlargeScreens?

No.

Sorta.

Resolution has nothing much to do with screen size. Screen size is self-explanatory: it is the size of the screen. I can have a 480x320 screen that is 1mm, 1cm, 1m, 1km, or 1 parsec in size.

Given resolution and density, you can compute a size, which is why your description of the normal screen size is close to correct.

The Range of Screens Supported section of the Supporting Multiple Screen Sizes documentation shows the diagonal screen sizes buckets that Android supports and what physical sizes those tend to map to:
