The "Catos Cluster"at Morcom Park in Oakland,Ca after not being pruned for a decade reached a grand size of 12-14 feet tall by c. 8 feet wide. (I'm 5'7" tall and it was well more than twice and nearly thrice as tall as I am)
I've rooted 8 plants,and in my experience it can easily be kept at c. 8 feet tall by c. 5-6 feet wide in N0rthern California. The last time I saw the mother plant at Vintagegardens it was c. 8 feet tall and grown as a climber against support. I plan to let mine grow to be closer to 12 feet tall x 8 feet wide,to provide privacy in my front yard.
For others who may be considering a pink Noisette:
"Catos' Cluster" is my absolute favorite pink Noisette for its'
-exceptionally lovely foliage, soft textured and of a pretty shade of green and the leaves are lavishly abundant.
-fragrance,similar to Autumn Damask to my nose.
-shapely pink roses that my neighbor calls my "carnation like rose", and a rosarian mistook for "Laure Davoust", but C.C. is fully remontant, blooming from April to November in our region.
I gave my Blush Noisette" away after rooting "Catos Cluster" because of the two I much prefer Catos Cluster" more shapely blooms (to my eyes B.N.'s appear a bit blousey and insipid of hue, and here I offer my heartfelt apologies to its' fans, who would champion B.N., however I do feel I am allowed to state my opinion) and foliage and fragrance.
As a large plant Catos Cluster is astoundingly beautiful. In my h. op.
Luxrosa.

Thank you so much, Luxrosa, for such wonderful details and the tip about the great specimen in Morcom Park! I have looked all over the Web and there's hardly even pictures (just a few), let alone any other info. I bought this rose primarily because of a previous post of yours and I am very glad I did -- I am already loving it. It will get the spot where it can get tall and wide. The flowers really are nicely shaped and scented and the plant seems very willing to bloom.
