If a product doesn't have its own dimensions supplied, then the ozpost default settings will be used instead.

I would suggest that you set these defaults to be something close to the size of the majority of items being sold, then add true dimensions to the individual products that don't fit this 'norm'.

Although for costing purposes the product dimensions will rarely affect the postage costs (unless subject to the cubing rules) the ozpost module depends on the dimensions to determine whether a given item can be classed as a letter or suitable for satchels (and if so, which size).
