The structure

The pyramid has a rectangular base with its long axis running north-south. It stands 64.6 metres (211.9 ft) from its supporting platform to the highest part of the roof comb

. Archaeologists estimate that 190000 cubic metres (6,709,786.6 cu ft) of construction material were utilised in the bulk of the pyramid. The temple faces eastwards towards the site core and supports a massive roof comb in pure Petén

 style, which was built upon the highest part of the structure's rear. It was hollow and was faced with an enormous mosaic sculpture. The architecture of Temple IV is broadly similar to that of the other major temples at Tikal, such as Temple I and Temple II.

The pyramid body itself, excluding the superstructure, consists of seven stepped levels with slanting talud

walls and multiple corners. The lowest of these levels measures 88 by, whilst the uppermost platform measures 38.5 by. The pyramid was built on top of an enormous supporting platform that measures 144 by; this platform had two levels and rounded corners; it was accessed via a 44 metres (144.4 ft) wide projecting stairway. The supporting platform was of very high-quality and utilised enormous stones in its construction.

The summit shrine was accessed via a 16.3 metres (53.5 ft) wide stairway that climbed from the supporting platform; a plain stela

They consist of tall sculpted stone shafts and are often associated with low circular stones referred to as altars, although their actual function is uncertain. Many stelae were sculpted in low relief,...

 (Stela 43) and the associated Altar 35 are centrally located at the base of the stairway. The shrine has been partially restored and has walls up to 12 metres (39.4 ft) thick. The shrine was built upon a platform resting upon a supplementary platform, which was in turn seated upon the top of the pyramid.

The supplementary platform measures 33 by with the longer axis running north-south. A stairway projects eastwards from this, giving access to the shrine itself. The supplementary platform is not exactly rectangular but consists of a number of architectural elements forming a complex plan. The platform resting on top of this measures 0.9 metres (3 ft) high; this element is poorly preserved, being visible only on the east side and in the middle of the north and south sides.

The roof comb is 12.86 metres (42.2 ft) high and consists of three distinct levels. The massive bulk of the roof comb was lightened by internal chambers, with four being built into each of the three levels. The roof comb was originally somewhat taller as evidenced by the bases of three smaller architectural elements on top.

The shrine

The shrine measures 31.9 by, with a maximum height of 8.9 metres (29.2 ft) excluding the roof comb. The exterior walls of the shrine are vertical, contrasting with the rest of the pyramid. The upper sections of the exterior walls formed a frieze

, with three giant stone mosaic masks facing eastwards over the temple access. The central mask was directly over the outer doorway, while the other two were near the northern and southern extremes of the building's facade.
The shrine had three chambers situated one behind the other, each linked by a doorway with a lintel fashioned from sapodilla wood. These three rooms were the only accessible chambers in the entire pyramid temple. The lintel of the exterior doorway was plain but the two interior lintels were intricately carved. These two were removed in 1877 by Gustav Bernoulli and are now found in the Ethnographic Museum in Basel

. The lintels were carved elsewhere and then moved to the pyramid, raised to the summit shrine and installed in prepared positions; this was a laborious task given that sapodilla wood weighs 1120kg/m3 (69.1lb/cubic foot). It was only after the installation of the lintels that the shrine was roofed and the roof comb built.
