-The witness size varies depending on the number of leaves it includes. Assuming the witness covers 1000 leaves, a witness for a Merkle trie would be about 3.5MB (assuming 7 levels to the trie). A witness for the same data in a Verkle tree (assuming 4 levels to the tree) would be about 150 kB - **about 23x smaller**. This reduction in witness size will allow stateless client witnesses to be acceptably small. Polynomial witnesses are 0.128 -1 kB depending on which specific polynomial commitment is used).
