Lot Size in Forex: Meaning, Purpose, Calculations, & More

Those who understand lot size in forex are better at managing risk and earning profits. But what exactly is a lot size in online forex trading, and how does it help simplify your Forex strategy? That is what we are going to cover in this article.

What is Lot Size in Forex Trading? 

The standardized volume or number of currency units traded in a Forex futures or options contract is known as the Forex lot size. 

Also known as the contract size, the lot size represents the amount of currency bought or sold in each trade. 

You’ll notice that the lot size for a Forex contract varies based on the underlying currency pair

In India, USD-INR, EUR-INR, and GBP-INR have a lot size of 1000 (in the base currency), whereas JPY-INR has a lot size of 1,00,000. 

Lots are divided into three types: Standard, Mini, and Micro. You’ll read all about this in the next section. 

For now, it’s important to note that it is essential to figure out the minimum lot size to know the capital required per trade. 

Knowing the lot size will also help you with risk management and position sizing, both of which are crucial to become a successful trader. 

In addition to all of this, you must also learn all about PIPs in forex trading. PIPs represent the smallest price movement in a currency pair, and they determine the profit or loss in a trade.

Types of Lots In Forex Trading 

A Forex contract may be traded in Standard, Mini, or Micro lots. Each type of lot size carries varying degrees of risk and reward while representing a different amount of units being traded. Let’s dig deeper into each of them.

1. Standard Lot

A standard lot is equivalent to 100,000 units of the base currency. Because of its significant volume, institutional investors and experienced traders frequently use the biggest lot size. 

One ordinary lot of trading here means the purchase or sale of 100,000 units of the base currency.

2. Mini Lot

A mini lot contains 10,000 units of the base currency. Retail traders appreciate it because it is one-tenth the size of a conventional lot and allows them to trade lesser quantities while still holding a sizable stake in the market.

3. Micro Lot

A micro lot contains 1000 units of the base currency. Since it is the lowest lot size that is offered, it is appropriate for traders looking to trade with little risk or with limited capital. 

There are multiple benefits to trading micro lots, ranging from more forex margin to better risk management and control over positions. 

How to Calculate Lot Size In Forex? 

When determining the lot size in Forex, some criteria must be taken into account, such as the trading currency pair, account balance, and risk tolerance. The following is the formula to determine the size of a lot:

Lot Size is equal to (Stop Loss in Pips * Pip Value) / (Account Balance * Risk Percentage).


The total quantity of money in the trading account is known as the account balance.

The portion of the account balance that the trader is willing to risk on a single deal is known as the risk percentage.

The distance in the pip between the entry price and the stop loss price is known as the stop loss in the pip.

The value of one pip for the currency pair being traded is known as the pip value.

Based on their risk management and trading goals, traders may use this method to calculate the right lot size for their transactions.

How Much is 1 Lot in Forex?

In Forex trading, the value of a single lot is determined by the currency pair being traded as well as the current exchange rate. One standard lot is equivalent to 100,000 units of the base currency for the majority of currency pairings. 

For example, one standard lot is equivalent to 100,000 yen for currency pairs if the Japanese yen (JPY) is the base currency.

Which Lot Size is Best for Forex Trading? 

The answer to this question is subjective to the traders. Traders who have low-risk tolerance and are just starting in the market can go for the micro or mini lots. Institutional investors and bankers usually trade in standard lots. 

What 1 lot means to a trader depends on their forex trading strategy for the market and the market conditions as well. So, if you are choosing a lot size in Forex, always look at your risk position and consider the fixed capital and risk tolerance that you have.
