# Parachain block fullness

Looking at a sample of 256 blocks for parachains of Kusama to see their block weights and how full they are.

Most of the blocks are empty as the tables below show. The blocks with zero block weight for normal transactions are skipped.

## Calculation

Code: https://github.com/Ank4n/polkadot-js-api/blob/parachain/src/index.ts#L50

- Get weight of the block using `system.blockWeight()`
- Calculate block fullness for each dimension `blockWeight.normal.dimension/max_dimension`.

**Max dimension values for parachain:**
- Ref_time: 0.5 sec
- Proof_size: 5 MB
