It really does depends, not only on the horse but on the saddle too - I have a couple of saddles and one uses a 42" girth, the other a 50" on the same horse!
ok, sounds like i need to wait until saddle arrives and measure it.its a close contact with quite short flaps so girth will need to be longer rather than shorter i imagine, its a similar shape to a pessoa.
my 16hh ISH took a 52 with her jumping saddle- she's now trimmed up a lot and takes a 48". i've just ordered a dressage saddle though and was told to buy a girth 20" shorter than her jumping girth...
in fact i've got a brown aeroborn 52" for sale at the mo that i never even tried on her! (has elastic at both ends) if you're interested?
yeah i'm the same - the stephens ones are what i use - normal and stud and will invest in a dressage one once i know what length i need (borrowing a few friends girths to find out optimum length before i buy!
)- love love love them - i just had this as a spare and never used it! was the only one for spare i could find that had two ends elastic!
