Using the above image and math i was able to come up with rough estimates of the area in square miles of each ocean.
total image 18,000,000 pixels
world 14,008,000 pixels = 197,000,000 sq mi
total land 4,910,000 pixels = 69,035,000 sq mi
Ezakonic Ocean 503,000 pixels = 7,012,000 sq mi
Lautian Ocean 2,298,000 pixels = 32,310,000 sq mi
Aigan Ocean 2,422,000 pixels = 34,053,000 sq mi
Tavaric Ocean 488,000 pixels = 6,861,000 sq mi
Hataric Mediterranean 88,470 pixels = 1,243,888 sq mi
Blood Sea 2626 pixels = 36,922 sq mi
Aqta Sea 9,553 pixels = 134,315 sq mi
Tavaric Ocean + previous seas = 588,000 pixels = 8,267,000 sq mi
Ranomic Ocean 1,744,000 pixels = 25,521,000 sq mi
Laharqan Ocean 566,000 pixels = 7,958,000 sq mi
Southern Ocean 929,000 pixels = 13,062,000 sq mi
All other Lakes/Seas 47,460 pixels = 667,288 sq mi
Added up to about 197.8 mill so not to far off the original.
