Physics says this:
BB-flat 19.34 ft.
CC 17.23 ft.
E-flat 14.48 ft.
F 12.9 ft.
B-flat 9.67 ft.
This is the affective length necessary based on A 440 and room temp etc. To get the actual or physical length you can subtract 60% of the bell diameter from these figures. This is the way I understand it anyway. Think you'll find it comes out roughly to what most people understand the lengths to be.
