Standard, mini or micro: which lot size do you actually use?

A standard lot is 100,000 units of the base currency, a mini lot 10,000 and a micro lot 1,000 — but plenty of platforms now offer 0.01 lots as their smallest size, which is where small accounts belong.

It helps other beginners to hear:

• your account size and typical position size
• whether your broker offers fractional sizes below 0.01 lots
• how position size changes when you trade a pair with a wider daily range

The lot sizes guide covers the full arithmetic.
