The longitudinal and transverse flux bundle sizes are
estimated for a three-dimensional single crystal Y-123
superconductor under a magnetic field along the $c$-axis
and the result is compared with previous results of Bi-2212
and Bi-2223. It is considered that the longitudinal flux
bundle size is determined only by the flux pinning strength
independently of the dimensionality of superconductor.
The number of flux lines in the flux bundle, $g^{\rm 2}$,
which is related to the transverse flux bundle size, is
estimated to be larger than 8. This number is much larger
than those in Bi-2212 and Bi-2223.
