I agree on location dependent. Having just moved from CA where cal king sheets were very easy to find and now living east of the Mississippi we can only find standard king sheets etc.

Sometimes Ross has both the King and the Calif King sheets, I live in Oregon and we have alot of California folks move here with the Ca. King beds, I even bought a Calif King headboad here in Oregon at a local furniture store, also Ross has great prices on linens, my son comes up here from California and buys his household linens and clothes here, he is a bachelor and likes to save on sales tax. Ross also has the high thread count sheets, I like the 500-600 the best otherwise they are too thin and shrink.

Availability of various King sized sheets seems to be location dependent. Std. King is readily available in the east, but Cal King seems to be almost all I can find in stores in CA. My best bet? Shop online.

You are backwards on the sheets; CA King sheets are much harder to find in retail stores. But to your point, the internet makes it very easy to have a wide selection.

Reference: I own a CA King bedset

I own an Eastern (Standard) King. If you are under 6'2" there is really no reason to get a CA King. The extra width is actually very enjoyable. You will use and appreciate that width much more then having extra length.

The downside is: CA King is much more common. So finding sheets for an Eastern King is much tougher. But thanks to the Internet, ordering sheets is really not that big of a problem. How often do you buy sheets anyway?
