6x9 (2.25 x 3.25) was a very popular format for roll film - both 120 and some older amateur formats.
The size that you can enlarge it will depend upon the level of detail in the original
(put a loupe to it and see how sharp it look) and also on the original films resolution.
I have 6x9's shot on modern films using a roll film back on a view camera that have been
used at 8'x12' size for murals. One of decent quality should be able to go fairly large (for consumer usage)
with no problem at all - 16x20 20x24 ... etc ....
A lot will depend on the quality of the scan. Find a local lab that caters to the professional trade
and have them do a high res scan for you and then see what it looks like after cleaning up.
If you want to go really large size it up to 100% and then crop a test patch out at 100%
and have a test print made to determine if it is going to hold up.
