Position Sizing: How Much Should You Actually Risk?
Position sizing is the single most important lever in crypto risk management. Learn the fixed-percentage method, how to size from your stop, and common mistakes.
Ask experienced traders what kept them in the game, and most will say the same thing: position sizing. It is the quiet discipline that decides whether a losing streak is a setback or the end of your account.
This guide explains how to size positions sensibly as part of your overall risk management. It is educational content and not financial advice — the numbers used are illustrative examples, not recommendations.
What position sizing means
Position sizing is deciding how much capital to put into a trade based on how much you are willing to lose if it goes wrong. It connects the size of your position to a defined risk, rather than to how confident you feel.
Confidence is not a risk control. Sizing is.
The fixed-percentage method
The most common framework is to risk a small, fixed percentage of your account per trade — often 1% to 2%. 'Risk' here means the amount you would lose if your stop is hit, not the total size of the position.
With 1% risk per trade on a $10,000 account, you would risk $100 per trade. Even ten losses in a row would only draw the account down about 10% — survivable. Risking 10% per trade instead, the same streak could be devastating.
Sizing from your stop
Your position size should follow from your stop distance. The wider your stop, the smaller your position must be to keep risk constant. A simple way to think about it:
- Decide the dollar amount you will risk (e.g. 1% of the account).
- Measure the distance from your entry to your stop, as a percentage.
- Size the position so that hitting the stop equals your chosen risk amount.
A worked example
Say your account is $5,000 and you risk 1% ($50) per trade. You want to enter a coin at $1.00 with a stop at $0.90 — a 10% stop distance. To risk only $50 with a 10% stop, your position would be about $500 (because 10% of $500 is $50).
If instead your stop were just 5% away, you could size up to about $1,000 for the same $50 risk. The risk stays fixed; only the size changes. This is the heart of position sizing.
Common position sizing mistakes
A few errors show up again and again:
- Sizing by gut feeling instead of a defined risk amount.
- Using leverage that turns a normal pullback into a liquidation.
- Increasing size after losses to 'make it back' — a fast path to ruin.
- Ignoring stop distance, so a wide stop quietly creates huge risk.
Why sizing beats prediction
You cannot control whether a trade wins. You can control how much it costs when it loses. Good position sizing means you never need a single trade to work out, which removes enormous emotional pressure and supports better trading psychology.
It also pairs directly with the risk-reward ratio: consistent sizing plus favorable risk-reward is what makes a strategy profitable over many trades.

Frequently asked questions
How do I calculate position size in crypto?
Decide how much you will risk (for example 1% of your account), measure the distance from entry to your stop as a percentage, and size the position so that hitting the stop equals that risk amount.
What is the ideal position size?
There is no universal ideal — it depends on your account, stop distance, and risk tolerance. Many traders keep risk per trade small and fixed. This is educational, not financial advice.
Why is position sizing important?
It decides how much a losing trade costs you. Good sizing keeps any single loss survivable, which matters far more than being right on any one trade.
Does position size depend on the stop-loss?
Yes. The wider your stop, the smaller your position must be to keep risk constant. Position size follows from your stop distance and the risk amount you have chosen.
