In Australia we do not have a big range of sizes or shapes of bee hives. They are all standard multi-storey Langstroth style with movable frames and a standard 19 inch top bar.
There are two widths, 8 frame and 10 frame, so called from the number of frames they can hold.
The further north in Australia the more likely the beekeeper is to use 10 frame width while further south they mostly use the 8 frame width.
The 3 sizes Penders supply are Full, Ideal and WSP.
