Measurement
Generally
speaking, a 20' container can hold as much as 28-30 cbm or
980-1,060 cu.ft., while a 40' can hold about 56-60 cbm
or 1,980-2,110 cu.ft. The actual loading Internal Capacity of
a container depends not only on the dimensions of the carton
boxes but also on many other factors such as the packaging material
and the competence and experience of the stuffing personnel.

Weight
Besides the cargo's measurement, the stuffing plan should also
take the weight into consideration. It is important to note that
in many countries the permissible weight limits for road and
rail transportation are lower than the maximum payload a container
can afford.
Use of Pallets
Palletization is widely applied in some countries to increase
cargo handling efficiency. When pallets are used, it is important
to observe that :
 There
are two major types of pallets, "Europallet" and
standard pallets. The size of the "Europallets" is
800mm x 1,200mm per piece while the size of standard pallets
is 1,000mm x 1,200mm per piece. A 20' container can hold eleven "Europallets" in
one tier or nine to ten standard pallets in one tier while a
40' container can hold 23-24 "Europallets" in one tier
or 20-21 standard pallets in one tier.
Wooden pallets must be strong enough to allow storage of three
tiers when loaded.
Carton boxes must not overhang the edges of the pallets. On the
other hand, boxes which utilize less than 90% of the pallet surface
and do not align with the pallet edge can shift in transit.
In many cases, pallets are replaced by slipsheets to save space.
some shippers use neither pallets or slipsheets in order to stuff
more cargo into the container.
