What is lot size? Forex is commonly traded in specific amounts called lots, or basically the number of currency units you will buy or sell. So, how much is one lot in forex? It depends on whether you’re trading a standard, mini, micro, or Nano lot. Forex trades are divided into these four standardized units of measurement to help account for small changes in the value of a currency.
Importance of understanding forex lots
Understanding lots in forex is important for a variety of reasons; the first is risk management. The lot size a trader chooses directly impacts their trade risk. The larger a lot size, the higher the profit or loss could be, and therefore the higher the risk.
Below are some other reasons why it is important to understand lots in forex:
- Account management: Forex brokers typically require a minimum deposit to open an account, and the lot sizes available may vary depending on the account type. Understanding lot sizes could help traders determine which account type is best suited to their trading style and account size.
- Trading strategies: Different trading strategies may require different lot sizes. For example, day trading may use smaller lot sizes, while long-term strategies may use larger ones. Understanding lot sizes could help traders choose a lot size that aligns with their trading strategy.
Standard Lots
A standard lot in forex is equal to 100,000 currency units. It’s the standard unit size for traders, whether they’re independent or institutional. A standard lot tends to be used by experienced and professional forex traders who have a larger trading account size and decide to take on higher risks.
Examples of Standard Lots
If the EURUSD exchange rate was $1.3000, one standard lot of the base currency (EUR) would be 130,000 units. This means, at the current price, you’d need 130,000 units of the quote currency (USD) to buy 100,000 units of EUR.
There are a number of scenarios in which traders could consider standard lots, these may include:
- High conviction trades: A standard lot could be considered by traders with a strong view on the market and confident about the direction of the trade.
- Long-term trades: Traders looking to hold a position for an extended period of time, such as several weeks or months, may prefer to use a standard lot. This is because the larger position size enables them to capture larger price movements over a longer period of time.
- Higher risk tolerance: Traders with a higher risk tolerance could potentially choose to use a standard lot. However, it is important to note that the higher level of risk tends to require a good understanding of risk management.
- Scalping strategies: Scalping strategies that involve making multiple trades in a short period of time may require a standard lot to generate a significant profit in a short amount of time.
Advantages of standard lots
- Higher potential returns: Trading with a standard lot could potentially result in higher returns as the lot size is larger, however, price movements against a trader’s positions could result in larger losses.
- Suitable for long-term trades: Standard lots are often used for long-term trades because they allow traders to capture larger price movements over an extended period of time.
- Better risk management: Trading with a standard lot could allow traders to manage their risk more effectively because it would allow them to calculate their potential losses and adjust their position size accordingly.
Disadvantages of standard lots
- Higher margin requirements: Standard lots require a higher margin requirement, which can be a barrier to entry for some traders.
- Short-term trading unsuitability: Trading with a standard lot may not be suitable for short-term trades or scalping strategies as the lot size could be too large to capture small price movements.
- Less flexibility: Trading with a standard lot may limit a trader’s flexibility to adjust their position size according to market conditions.
Mini lot
A mini forex lot is one-tenth the size of a standard lot. That means a mini lot in forex is worth 10,000 currency units. The size of a mini lot means the profit and loss effect is lower than a standard lot.
Example of Mini Lot;
If the EURUSD exchange rate was $1.3000, one mini lot of the base currency (EUR) would be 13,000 units. This means, at the current price, you’d need 13,000 units of the quote currency (USD) to buy 10,000 units of EUR. Mini lots tend to be used by retail traders who have smaller trading accounts and want smaller positions in the market. Here are some scenarios where a mini lot could be considered:
- Low risk tolerance: Traders who have a low risk tolerance or are new to forex trading may choose to use a mini lot as it allows them to take smaller positions and limit their potential losses.
- Scalping strategies: Scalping strategies that involve multiple trades in a short period of time may require a smaller position size to generate a significant profit in a short amount of time. In such cases, a mini lot can be a suitable option.
- Testing new strategies: Traders who are testing new trading strategies may choose to use a mini lot to limit their exposure to the market until they have more confidence in their strategy.
- Diversification: Traders who want to diversify their portfolio by taking smaller positions in multiple currency pairs may prefer using a mini lot.
- Smaller trading account size: Traders who have a smaller trading account size may choose to use a mini lot as it allows them to take smaller positions and still participate in the forex market.
Advantages of mini lots
- Lower risk: Trading with a mini lot carries lower risk as the potential losses are smaller compared to trading with a standard lot.
- Lower margin requirements: Trading with a mini lot requires lower margin requirements compared to trading with a standard lot. This makes it more accessible to traders with a smaller trading account size.
- Better flexibility: Trading with a mini lot allows traders to have better flexibility in adjusting their position size according to their account balance and risk tolerance.
- Suitable for short-term trades: Trading with a mini lot can be suitable for short-term trades or scalping strategies as the lot size is smaller and can capture smaller price movements.
Disadvantages of Mini lots
- Lower potential returns: Trading with a mini lot results in lower potential profits compared to trading with a standard lot as the lot size is smaller.
- Less priority in pricing: Traders with smaller positions are often given lower priority by liquidity providers, which could result in worse pricing and execution compared to traders with larger positions.
- Limited participation in certain strategies: Trading with a mini lot may limit participation in certain strategies that may require larger position sizes.
- Higher spread percentage: Trading with a mini lot may result in a higher spread percentage compared to trading with a standard lot, as some brokers charge a higher spread percentage for smaller lot sizes.
Micro lot
A micro forex lot is one-tenth the size of a mini lot. That means it’s worth 1000 units of currency. Pip movements result in a cash swing of 1 currency unit, eg €1 if you were trading EUR. Micro lots also require less leverage, so a swing won’t have as much of a financial impact as with larger lot sizes.
Example Mini lot:
If the EURUSD exchange rate was $1.3000, one micro lot of the base currency (EUR) would be 1300 units. This means, at the current price, you’d need 1300 units of the quote currency (USD) to buy 1000 units of EUR.
Micro lot could be considered by traders in various scenarios, including:
- Limited capital: Traders who have limited capital to trade with may choose to use micro lots. These lots could allow them to participate in the forex market with a smaller account balance and still have the ability to trade.
- Risk management: Micro lots can also be used for risk management purposes. Traders who want to limit their exposure to the market may choose to trade with micro lots to keep their position sizes small and minimize the impact of any losses.
- Testing strategies: Some traders may also use micro lots to test out different trading strategies. By using a small position size, they can see how their strategy performs in real market conditions without risking too much capital.
Advantages of Micro lots
-
Lower risk: Trading with micro lots allows traders to take smaller positions, which reduces their risk exposure. This is especially beneficial for beginner traders who are still learning the ropes and may not be comfortable taking larger positions.
-
More flexibility: Micro lots give traders more flexibility in terms of their position sizes. They can open and close positions in smaller increments.
-
Lower capital requirements: Trading with micro lots requires less capital than trading with standard or mini lots.
- Frequent trading option: Micro lots allow trade with higher frequency if they choose, as they can enter and exit the market repeatedly without risking too much capital.
Disadvantages of Micro lots
- Limited return potential: As the position size is smaller with micro lots, potential returns are also limited.
- Higher transaction costs: Trading with micro lots can result in higher transaction costs due to the need to open and close more positions. This could eat into profits and make it more difficult to achieve a positive return on investment (ROI).
- Limited market exposure: Trading with micro lots can limit a trader’s exposure to the market as they are not taking on as much risk as they would with larger position sizes.
- Limited strategy options: Some trading strategies may not work as well with micro lots, as the smaller position size could potentially limit the effectiveness of certain techniques.
Nano lots
A Nano forex lot is one-tenth the size of a micro lot. It’s equal to 100 units of currency. A one-pip movement with a micro lot is equal to a price change of 0.01 units of the base currency you’re trading, eg €0.01 if you’re trading EUR.
Example of Nano Lots:
If the EURUSD exchange rate was $1.3000, one Nano lot of the base currency (EUR) would be 130 units. At the current price, you need 130 USD to buy 100 EUR.
Advantages of Nano Lots

Choosing a lot size in forex
Choosing the right lot size in forex is crucial for returns and risk management. Traders should look at their account size, and knowledge of the market along with other factors, including:
- Risk tolerance: Risk tolerance is an important factor to consider. Risk-averse traders may choose smaller lot sizes to limit market exposure, while others may be comfortable with larger positions.

- Market conditions: Market conditions, such as volatility and liquidity, can also affect your lot size. In volatile markets, traders use smaller lot sizes to manage risk, while in liquid markets, they can take larger positions.
- Trading platform: The platform traders use could also limit the lot sizes available to you. Some platforms may only allow trading in standard or mini lots, while others may offer micro or even Nano lots.
How to calculate lot size in forex
The formula for calculating lot size in forex depends on the currency pair and your account size.
Step 1: Determine the risk you are willing to take
To calculate lot size, first determine your risk level for the trade. This is usually expressed as a percentage of your account balance or a fixed dollar amount.
Step 2: Calculate the position size in units
Next, you need to calculate the position size in units. The formula for this calculation depends on the currency pair you are trading and the size of the lot.
For a currency pair with USD as the base currency and a 100,000-unit lot size (standard lot), use this formula
Position size = Risk amount / (Stop loss in pips × Pip value per lot)
Where:
- Risk amount is the amount traders are willing to risk on the trade.
- Stop loss in pips is the number of pips from your entry price to the stop loss level.
- Pip value per lot is the value of one pip for the currency pair you are trading.
Step 3: Convert the position size into lot size
Once you have calculated the position size in units, you can convert it into lot size. To do this, you need to divide the position size by the lot size. For example, to find the number of lots for a mini lot (10,000 units), divide the position size by 10,000.
Lot size = Position size / Lot size
There are three types of lots in forex. A standard lot is the largest, representing 100,000 units of the base currency in a pair. A mini lot is 10,000 units of the base currency, and a micro lot is 1,000 units.
Depending on whether you are starting out in trading or an experienced trader, will determine which lot size you go with. Choosing the right lot size is crucial as it impacts your performance and risk management. Traders should research thoroughly and avoid risking more than they can afford to lose.
