Reportedly 72 ft (22 m). If it turns out to be part of the aircraft, that's pretty close to the length of half a 737-8 wing with the centre wing box attached.
That could suggest it was no longer attached to the fuselage (and falling considerably more slowly, hence remaining relatively intact) by the time it hit the water.
