The oceans all blur into each other making it hard to neatly define.
The Indian Ocean is generally quoted up as measuring 68.556 million square kilometres. On the map it measures (roughly) 7388 km by 5828 km in extent (4591 x 3622 miles), but those dimensions don't include all the Gulfs, Channels, straits and small seas that it extends into (e.g., Malaysia).
The Indian Ocean touches on to more than 66,000 km of coastlines, and at its deepest reaches depths of about 7530 m.
