Wiki ( https://wiki.openstreetmap.org/wiki/Key:surface ) lists paving_stones:30 and paving_stones:20 as good values for key surface, defined as "Square paving stones with 30cm/20cm sides".
I think it is a really bad idea, there is a really wide variety of sizes of paving stones and cobblestones, so it would doom as to many variations of these tags. What worse, it already started - see https://taginfo.openstreetmap.org/keys/surface#values and search for : sign among values. Information about size of paving stones is not so important to mark it by introducing wide set of values in tag "surface". I propose to remove this value from list on wiki or at least mark it as a poor idea. Forming consensus whatever we want surface=cobblestone:8, surface=cobblestone:9, surface=cobblestone:10, surface=cobblestone:11 etc tags would be a good idea to guide data consumers which kind of tags should be supported by a reasonable application. <https://taginfo.openstreetmap.org/tags/surface=cobblestone%3A10>
