What size spanners do you need for 22mm straight compression fittings?
The nuts are 32mm but what about the flange on the middle of the body?
I measured it with a vernier calliper and I think it was 28.5mm, which
seems an awkward size. Rounding that up to 29mm, I could not find any
29mm spanners anywhere. Would a 30mm spanner be too big or do you
"cheat" and use adjustable ones?

I'd say it might also depend on the make of fitting - some still seem to
use the old imperial sizes on the body. Luckily I have a fair selection of
such spanners so just use one that fits.

This chart might help you guess what it is :-
