The bulge is maximum of about 21 km, at the equator longitudes of the oceans and tends to zero at the poles.

Explanation:

Earth is an oblate spheroid.

The equatorial radius is 6378 km and the polar radius is 6356 km,

nearly.

This difference is generated through latitudes #0^o#, at the equator,

and #90^o#, at the poles.

The rate of descent #= 21/90# km/degree

= 23.56 meters/ degree, nearly.,

The measure of the bulge along land/oceans of the equator is

about 21 km,

I think that I have made the answer quite informative.
