In Australia, there are some more permutations of super and frame sizes. The main super sizes are as follows:
Full Depth - 9 1/2" or 241mm - frames about 232mm
Manley - 6 5/8" or 168mm - frames about 159mm
WSP - 7 1/2" or 190mm - frames about 181mm (some suppliers WSP stuff is 195mm)
Ideal - 5 3/4" or 146mm - frames about 136mm (similar to US shallow supers I think)
Half size - 5" or 127mm - frames about 118mm (I have never seen any of these though)
The sizes vary a bit between manufacturers (+- a few mm) due to the amount bee space allowed etc.
The WSP supers (named after Wyn Pender, an Australian manufacturer of beekeeping gear) came about during WW2 as I understand as it became difficult to get boards 240mm or so wide, while there was a reasonable supply of 190mm wide timber. The Manley and half height sizes are an English invention to try and make the weight of full supers a bit more manageable. However, most Australian beekeepers seem to use mostly either full depth or ideals or some combination. One of the bigger commercial apiary operations here have recently been cutting their WSP gear down to ideal size to get lighter and more standard, interchangeable gear. We used to use full depth for the brood box and ideals for the honey supers (and occasionally full depth honey supers), now a lot of beekeepers are using all ideal sized gear.

Everyone seems to have their own subtle take on Langstroth super and frame sizes.
