The vortex-matter 3D to 2D phase transition is studied in micron-sized Bi{sub 2}Sr {sub 2}CaCu{sub 2}O{sub 8+{delta}} single crystals using local Hall magnetization measurements. At a given temperature, the second magnetization peak, the signature of a possible 3D--2D vortex phase transition, disappears for samples smaller than a critical length. We suggest that this critical length should be equated with the 2D vortex lattice ab -plane correlation length R{sup 2D}{sub c} . The magnitude and temperature dependence of R{sup 2D}{sub c} agree well with Larkin-Ovchinnikov collective pinning theory.
