Are you doing this from a filter?  If so, the correct way is to combine the options from argv[5] with the PPD defaults, and then query the current size using ppdPageSize:

    ppd_file_t *ppd = ppdOpenFile(getenv("PPD"));
    cups_option_t *options = NULL;
    int num_options = cupsParseOptions(argv[5], 0, &options);
    ppd_size_t *size;

    ppdMarkDefaults(ppd);
    cupsMarkOptions(ppd, num_options, options);

    size = ppdPageSize(ppd, NULL);
