What is the minimum rank required to enter the main draw of either a grandslam or a masters tournament?

Question

without going through the qualifying rounds?

Answer 1

this is different

in grandslams there are draws of 128. 16 places are for qualifiers (men) and 12 (women). furthermore you have to take in calculation some wildcards, sometimes up to 12.

so the rank for a direct qualification is something between 100 and 106 depending on the number of wildcards.

master series tournament have draws of 96 (Indian Wells and Miami) the rest have draws of 56. number of qualifiers is 12 resp. 7.

the rank for direct qualification is therefore around 76 - 80, resp. 42 - 46.
