The Polynesian and CR have the largest standard rooms, followed closely by the GF. (They are so close you really can't tell much difference IMHO, although many of the Polynesian rooms don't have the split bath.)
The BWI/BC/YC are all identical in size and layout, with an odd exception here or there. They are a nice size, but not as large as the prior three.
As mentioned previously, the WL/AKL rooms are the smallest of the deluxe properties, although not closet sized by any means. For just a little more $$ at the AKL you can get a deluxe room which is definitely a little more spacious. Also, if you do'nt need the daybed, some of the rooms at the AKL have a comfy chair rather than the daybed, giving more space.
