Unit Sizing in Sports Betting | How Much to Bet
Definition
Unit Sizing in sports betting how to size your bets to survive variance.
Think of it this way
Like budgeting your allowance - spend 5% per thing so you last the whole month.
Unit Sizing
A unit is your standard bet size. It keeps you consistent and protected from variance.
The Allowance Analogy
Imagine you get $100/month allowance.
Bad approach: Spend $50 on one thing, run out of money. Good approach: Budget $5-10 per purchase, enjoy the whole month.
Units work the same way.
What Is a Unit?
A unit is 1-2% of your total bankroll.
| Bankroll | 1 Unit | 2 Units |
|---|---|---|
| $500 | $5-10 | $10-20 |
| $1,000 | $10-20 | $20-40 |
| $5,000 | $50-100 | $100-200 |
Why This Matters
At 1-2% per bet, you can survive:
- 10+ losses in a row
- A terrible month
- Normal variance swings
At 10% per bet, a bad week ends you.
Flat Betting vs Variable
Flat betting (recommended): Same unit on every bet. Variable: Adjust size based on confidence (risky for most).
Start with flat betting. It removes emotion from sizing.
DMP Note
We recommend 1 unit for standard plays, 1.5-2 units for high conviction only.
Units are your survival tool. Ignore them at your peril.
How DMP uses this
DMP helps you track unit-based results, which matters more than dollar amounts.
Common mistake
Betting 10% of bankroll on a "lock." There are no locks. Size for survival.
After this lesson
You can calculate and apply proper unit sizing to any bankroll.
