The size of the storage unit you should get depends on the
amount and type of items you plan to store. It's important to choose a unit
that is large enough to accommodate all your belongings without being too
cramped. You can start by making an inventory of the items you want to store
and estimating their total volume. This will give you an idea of the size of
unit you need. Additionally, you may want to consider any future storage needs
you may have, as it might be more cost-effective to rent a slightly larger unit
now rather than having to upgrade later.
