The Jetawanarama , when it was measured in recent times, was around 97 metres (232 feet ) in height. However, this was after its pinnacle had been damaged. The original height of the dagoba,with the pinnacle intact, was around 130 metres(400 feet) according to the chronicles. Its base was about 120metres (367 feet ) in diameter.

The dagoba is constructed entirely of bricks and is said to be the largest brick made dagoba in the world. Investigations conducted at the site have revealed that it stands on a brick foundation which is 26 feet thick, below which there is another concrete foundation. It is built in the shape of a babble.
