# Lot Size

*Trading & Technical Analysis — Finicade finance glossary*

Lot size is the standardised quantity a trade is denominated in — 100,000 units for a standard FX lot, 10,000 for a mini, 1,000 for a micro. It's the multiplier that converts a tiny price move into a meaningful sum, and choosing it is position sizing in practice. Trading a standard lot on a small account is how leverage quietly becomes 50:1 exposure.

**Also known as:** standard lot, mini lot, contract size
