For any kind of your move, it is good to choose Medium Boxes of 3cft (18 x 18 x 16) for packing most of the items and use Large Boxes of 4.5cft (24 x 18 x 18) only for Bulky items. The use of Medium Boxes keeps things intact during a drive and does not let things fall apart.
If you are moving Interstate, check whether your mover offers a neutral negotiation program to resolve disputes in case of loss or damage to any of your items. Prior knowledge of your mover’s dispute settlement program is recommended.
