Can someone offer advice regarding choice of crown mouldning

What I want to do is install crown moulding on the lower level
of a two story house. Rooms are fairly small.... two are 12 x 15
one is 10 x 12. There is an entry hallway leading from front'
door to kitchen. Ceilings are 8'

I think 4 1/8 inch would work in the larger rooms. But a smaller
size is needed for the hallway which is about 36" wide x 12 ' long.

Would 3 5/8 " work in the hall or would a smaller size be
appropriate.???

What options are available ??? a look at the focal point products
does not show any moulding that comes in varying sizes.... are
there other suppliers with matching designs ???

Are there any web sources or books which might show recommended
sizes for different applications or is this an 'eyeball' type of
choice.

Look at the local lumber yards for samples. The big box places are OK
for this, but give the local guys a shot too.

Buy some two-foot pieces to use for samples. Stick them up on the wall
with masking tape, then step back and imagine the sample around the
whole room.

If you're going to paint it anyway, consider the composite stuff. It's
very uniform and paints well. Get the pre-primed stuff. Paint it before
you put it up--your back will thank you.

Going from a room to a hall with different sizes can be an issue.
Consider corner blocks. They allow you to butt two sizes to a corner
without it being so noticeable.
