Estimate tree depth and sibling-hash proof size for a Bitcoin-style Merkle tree.
How it works
The calculator applies the documented Bitcoin or BIP rule to the values you enter and returns a mathematical or serialization estimate. Protocol implementation details and real wallet behavior remain authoritative.
The formula
Leaf count • Hash size (bytes)
Worked example
5 leaves with 32-byte hashes → depth 3 and 96-byte sibling-hash proof.

Frequently asked questions
What does this calculator estimate?
Estimate tree depth and sibling-hash proof size for a Bitcoin-style Merkle tree.
Should I enter a seed phrase or private key?
No. Never enter a recovery phrase, seed phrase or private key into this or any web calculator. These tools are designed to work without secret key material.
Is the result a security or financial guarantee?
No. It is an educational technical estimate based on the selected assumptions and cited specifications. Real software, wallet policy, network rules and correlated failures can change outcomes.
