Real Housewives of Beverly Hills stars Kim and Kyle Richards definitely have big personalities, but physically the two sisters are quite diminutive. Though Kyle is taller, at 5-foot-2 she’s only an inch taller than her petite older sister!

We quizzed Viggle LIVE! users during the March 24 reunion episode to see how well they knew the Richards sisters. As it turns out, they acquitted themselves quite well! Half — 50 percent — correctly guessed that Kyle was taller, while only 28 percent thought Kim was the big sister both in age and stature. The remaining 22 percent thought they were the same height, though who can blame them with such a small difference between the two?

Honestly, with the sky-high heels these women all wear on a daily basis, it’s a little hard to tell how tall any of them are. For the record, Brandi Glanville is a statuesque 5-foot-10 and Joyce Giraud stands at 5-foot-9. Lisa Vanderpump recently revealed on Twitter that she is 5-foot-5, while Carlton’s height remains a mystery.
