The three chariots used in the Puri Jagannath Rath Yatra have specific size and dimensions and are a classic example of indigenous carpentry and engineering. You can find more details about the sizes and other measurements of each chariot in this article – the size and dimensions of the Puri Jagannath Rath Yatra chariots.
No scales or measuring tapes are used by the carpenters for measurements. Instead the carpenters use their hands and fingers to build the giant chariots.
Each year nearly 1000 trees are felled for the making of the chariots. Equal number of trees are also planted each year under the Sri Jagannath Bana Sankalpa Program.
There was a suggestion to reuse the woods used but it was opposed by the priests and by a section of Jagannath devotees. Currently the woods are dismantled after the end of the Rath Yatra and are used for cooking the Mahaprasad.
