Most modern computers can easily handle 16 bits, but it is slower than an 8-bit system. A practical programming rule of thumb is to choose a data type that can hold a value bigger than you think can realistically ever occur, then choose the next larger size data type. This should be taken into account when interfacing with low-level code (such as C or Fortran) where the raw memory is addressed.
