It is correct that FIX fields have variable length. However the underlying trading system of the counterparty, e.g. an exchange, normally have a field length restriction on almost every field and will reject messages were the field length exceeds that maximum allowed. The reason of field lenght restrictions may be:
- Secondary storage in databases.
- Integer fields are converted to binary fields
- Underlying system cannot allow unlimited length fields as it might
overflow buffers and have serious impact on performance.

The field length restrictions should be bilaterally agreed between the two parties.
