The shape of the Naveta d'Es Tudons is that of a boat upside down, with the stern as its trapezoidal façade and the bow as its rounded apse.
Its groundplan is an elongated semicircle.
Externally, the edifice is 14.5 m long by 6.5 m wide and 4.55 m high but it would originally have been 6 m high.
It is orientated SWS/ENE, the entrance being at the SWS, in the centre of the slightly slanted (or battered) façade.

The front, side walls and apse of the edifice consist of successive horizontal corbelled courses of huge rectangular or square limestone blocks dressed with a hammer and fitted together without mortar, with an all-round foundation course of blocks of even greater size laid on edge.

The narrow, low entrance doorway (0.57 m x 0.75 m) is rebated to receive a closing slab.
The once sealed-off entrance leads by a short, flag-roofed passage to an antechamber 1.3 m long and then another short passage to the main or lower chamber (7.45 m x 2.45 m), the ceiling of which is made of giant horizontal slabs inserted into the side walls, with an average span of 1.5 m c. 2.25 m above the floor.
Above this is an upper chamber which is accessible from the upper part of the antechamber.
It is slightly shorter (7.10 m) and narrower (1.90 m) than the lower chamber, with a similar although much lower (0.85 m) ceiling of horizontal slabs.
These have holes in them, presumably for ventilation.
