In engineering , the definition of dimensions based on objective criteria during the design process is called measurement or dimensioning, depending on the discipline . The criteria can be based on empirical values, take into account physical laws or be based on legal requirements . The assessment bases and procedures are regularly laid down in technical regulations and national and international standards . As a rule, dimensioning is also understood to mean the definition of the properties of the material to be used . The starting point of the design process are the requirements that are placed on the object to be designed. The aim of dimensioning is to determine the necessary and optimal size or load capacity of a component using a calculation process or from a table . The dimensioning is documented in writing for test purposes (if necessary).

Preliminary dimensioning

The final dimensioning can only take place after all planning stages have been completed, as all the necessary parameters are only determined at this point in time. In order to get a more concrete idea of ​​the dimensions of the planned components during the planning process, as well as to prove the basic feasibility, these are usually pre-dimensioned . Rough assumptions are made about the expected results of the dimensioning on the basis of simplified defined rules and the further planning process proceeds on the basis of these assumptions.
