General Rhodactis full grown size?

[John3]

I have a few different types of Rhodactis and I am wondering how large can they typically get. Everything I normally see for sale is about the size of a quarter but last weekend I saw a few at a lfs that were maybe 3”. So I’m wondering if most have the ability to get that big?

I've seen some as wide as 6 inches, I've personally had one that grew to at least 4 inches across.

Mine split at 3" or so. Now both are as big as the first was when I brought it home. I hope they both split again.
