Well, there's going to be much less space further from the equator, as parallels on both directions from equator are getting shoter and shorter. The equator is 40,000 km long, but the parallel I live on (50th north) is just 25,000 kilometers long (if I'm correct).
Actually around equator is mostly sea. And land space is rather irregularly distributed over the earth.
Well, I wonder if there is some specific latitude where there's more land than sea, of course, except Antarctica.
Seems more like clustered around 30 degrees north.
