Forex Lot Size Definition: Standard vs Micro

Editorial Note: While we adhere to strict Editorial Integrity, this post may contain references to products from our partners. Here's an explanation for How We Make Money. None of the data and information on this webpage constitutes investment advice according to our Disclaimer.

Forex lot size refers to the number of currency units traded. A standard lot is 100,000 units, while a micro lot is 1,000 units. Standard lots suit experienced traders, while micro lots help beginners manage risk with smaller trades.

Lot sizes are important in Forex trading because they affect both risk and profit. Standard lots are a common choice, offering bigger returns but also carrying higher risks because of their large size. Micro lots, on the other hand, are a tiny portion of a standard lot and are great for lowering risk. While profits are smaller, they help you learn with less risk and allow you to refine your strategy without putting too much money on the line. No matter what lot size you choose, picking the right one for your account and risk tolerance is key to keeping risk low and trading well.

What is a typical Forex lot size?

Types of Forex lot sizes

Lot sizes range from standard lot sizes all the way down to nano lots and are based on the amount of currency you’ll trade with each lot.

Different Forex lot sizes
Lot	Units of Currency
Standard Lot	100,000
Mini Lot	10,000
Micro Lot	1,000
Nano Lot	100

Standard Forex lot definition

As shown in the table, a standard lot equals 100,000 units of the base currency in a currency pair. For example, in the EUR/USD pair, the base currency is the EUR, so a standard lot is 100,000 EUR.

Here’s a simple example: if you trade the USD/CAD pair with a standard lot, you’re actually trading US$100,000.

This means price changes can strongly affect your account balance. In currency pairs based on the US dollar, one pip equals about $10 when trading a standard lot. So, a 20-pip move means a $200 profit or loss.

Because of this, standard lots come with high risk and are mostly used by large traders or professional full-time traders.

Mini lot

Smaller than standard lots, mini lots equal 10,000 units of the base currency in a pair. In simple terms, one standard lot equals 10 mini lots.

For example, with EUR/USD, a mini lot equals 10,000 EUR. This means price changes affect your balance less, with each pip worth about $1 in a USD-based pair.

With that in mind, mini lots mean lower profits but also lower risk. However, make sure you have enough funds, as market moves can still impact your account balance significantly.

Micro-lot and nano-lot

Beyond mini lots, there are micro and nano lots. A micro lot is one-tenth the size of a mini lot or one-hundredth of a standard lot, meaning it equals 1,000 units of the base currency. In a US dollar-based currency pair, one pip movement is worth about $0.10 when trading micro lots.

On the other hand, a nano lot equals 100 units of the base currency, making it one-tenth the size of a micro lot. For US dollar-based pairs, one pip is worth just one cent.

This is why many beginners start with micro or nano lots — they help control risk. But remember, not all brokers offer micro lots, and nano lots are even harder to find.

Lot size in cent (micro currency) accounts

A cent account is a type of trading account where your balance and transactions are displayed in cents rather than dollars. For example, depositing $20 into a cent account will show a balance of 2,000 cents.

How cent accounts work

Cent accounts let you trade real money while keeping risk low. Example: to trade 0.1 lots of USD/CAD without leverage, you’ll need $100 or 10,000 cents in your account. Here, each pip is worth 1 cent, making it great for new traders to test platforms, strategies, and risk management without putting much money at risk.

Benefits and drawbacks

Cent accounts are a safer way to practice Forex trading. However, since profits are small, the mindset shift from trading in cents to dollars can be tough, and they don’t fully prepare traders for standard accounts. Still, they’re a great first step for beginners.

What lot size should you use when trading Forex?

The best lot size to use in Forex trading depends on your goals, risk tolerance, and trading experience. Beginners should start with micro lots or cent accounts to minimize risks, while experienced traders with higher capital and profit goals may opt for mini or standard lots.

Choosing the right lot size

For beginners, micro lots (1,000 units) or cent accounts work best. These options let traders get real experience with small amounts of money while avoiding big risks. They give a safer way to build skills and test strategies without risking too much.

For experienced traders or those looking to trade full-time, standard lots (100,000 units) can bring bigger profits but need a large account and strong risk control.

Mini lots (10,000 units) offer a middle ground, good for traders who want to increase profits without huge risk.

Key considerations

No matter your lot size, managing risk is key. Too much leverage increases losses fast, so keep enough money in your account to handle trades. The right lot size should match your financial goals while helping you trade safely long-term. Also we recommend choosing a reliable Forex broker with a cent or a micro account.

Smart traders layer lot sizes instead of going all-in

Most beginners think choosing between a standard or micro lot is just about account size, but it’s actually about survival. A standard lot (100,000 units) moves $10 per pip, meaning just a small market swing can wipe out an underfunded account. Micro lots (1,000 units), moving at $0.10 per pip, let traders last longer, but the real advantage isn’t just smaller risk — it’s flexibility. The best traders mix lot sizes dynamically, scaling in and out of trades rather than sticking to one fixed size. If you only trade with a single lot type, you’re leaving money on the table and making risk harder to control.

Smart traders don’t just pick a lot size — they layer them. Instead of entering a full position at once, break it into smaller entries. Start with a micro lot to test the waters, then add more as the trade confirms. This way, if the market moves against you, your losses stay minimal, and if it moves in your favor, you’ve got a solid position growing. Most traders lose not because of bad trades, but because they go all-in too soon. The key isn’t just choosing a lot size — it’s knowing how to use it like a tool, not a bet.

Summary

Hopefully, this post helped illustrate the different lot sizes in more detail, how they’re calculated, and what lot size you should use when trading Forex. In summary, standard lots provide higher leverage but more risk, while micro lots enable smaller traders to practice with lower risk but also lower profit potential per trade. The choice depends on an individual's experience level and risk tolerance.

FAQs

Is there a difference between trading standard lot sizes and micro lot sizes?

At their core, there’s no difference between trading in the different lot sizes. However, as trading in larger lot sizes involves more capital, the risk increases.

What lot sizes should I use when trading?

Ultimately, what lot size you choose when trading depends on your specific goals and risk appetite.

I’m a beginner, should I trade with standard lot sizes?

Nothing prohibits you from trading with standard lot sizes, but the risk might be too significant, especially when you’re a beginner. For this reason, it’s better to start trading with micro lots or cent accounts.

How much funds do I need to start trading Forex?

Considering that many Forex brokers don’t have any minimum deposit requirements, you can start off with as little money as you prefer. However, if you start off with an account balance that’s too small, you’ll often need to use too much leverage which increases your risk substantially.
