Here's a
link to the DIS site's page about SSR.
These are the sizes of the SSR villas
SSR Studio - 355 sq. ft
SSR 1 bedroom - 714 sq. ft.

And here's a
link to the DIS site's page about OKW.
These are the sizes of the OKW villas. The Studios are close to the same size, but the OKW one and two bedrooms are considerably larger.
OKW Studio - 376 sq ft.
OKW One Bedroom - 942 sq. ft.
OKW Two Bedroom - 1,333 sq ft
Here's the SSR map
In case it won't put the map on the post, here's the link:

And here's the OKW map
When you look at the maps, SSR doesn't look that much bigger than OKW, but the scale of the maps is different and SSR is actually a lot larger.
We have stayed at both resorts.
OKW is our home resort, so we have stayed there more, but we have stayed at SSR 4-5 times. When we stayed at OKW in building 48, it was a fairly slow 10 minute walk from there to the Hospitality House. I'd estimate our walk to get from SSR Carriage House from Congress Park building 1101-1436 in the part closest to the Carriage House was about the same distance.
