Size Reference
Overhead: 10 bytes (legacy) or 10.5 vB (segwit: +2 witness bytes for marker/flag at ¼ weight)
Inputs: P2PKH 148 B · P2SH-2of3 297 B · P2WPKH 41 base + 107 wit = 68 vB · P2WSH-2of3 43 base + 252 wit = 106 vB · P2TR 41 base + 66 wit = 57.5 vB
Outputs: P2PKH 34 B · P2SH 32 B · P2WPKH 31 B · P2WSH 43 B · P2TR 43 B
Formulas: weight = base×4 + witness · vSize = ⌈weight / 4⌉ · size = base + witness
