box size for tenor for shipping

Can anyone tell me the dimensions of a typical box used to ship a tenor ukulele in its case?

I am considering selling one or more ukes and need to get some boxes for it/them.

Thanks in advance.

I normally use a standard available uline box, 32”x 12”x 10” for tenors, but 32”x 12”x 8” would be better.
Baritones need a bigger box 36”x 14”x 10”.
This is for shipping ukes in cases.
