It is difficult to answer, though one thing is certainly for sure, and that is that 7 inch records will be cheaper to press than 12 inch records and 10 inch records, even if only for the fact that they use an inherently smaller amount of the essential material, polyvinyl chloride, as part of the process. However, it might be worth considering the fact that 7 inch records are not quite as hot a commodity as they once were, meaning their relative specialism in comparison to the 12 inch record could result in higher overall costs to produce.
