Betting Units Explained: What 1u Means and How to Size Your Bets
What a unit is, why every serious bettor talks in units instead of dollars, how to pick your unit size, and when a bet deserves 1u, 2u, or 3u.
What a unit is
A unit is your standard bet size, defined as a fixed percentage of your bankroll — most commonly 1%. If you've set aside $2,000 for betting, 1u = $20. Units make records comparable across bankrolls: "+14u on the month" means the same thing whether your unit is $5 or $500.
Units also expose fake handicappers instantly. Anyone posting "$500 winner!" without a unit-based record is hiding the denominator. Profit is only meaningful relative to risk.
Choosing your unit size
1% of bankroll is the standard; 2% is aggressive; 5% is how bankrolls die. The math is unforgiving: losing streaks of 8–10 bets happen routinely to good bettors, and at 5% a normal cold stretch costs half your roll — which forces desperate betting, which finishes the job.
Pick a bankroll number you genuinely would not miss, divide by 100, and that's your unit. The goal of sizing isn't to get rich this month; it's to guarantee you're still solvent when your edge finally gets its sample size.
When to bet more than 1u
Scale stakes to edge, not to confidence-the-feeling. A bet deserves more units only when the measurable gap between your probability and the market's is larger. Feelings about a game are worth exactly zero extra units.
That's how our board works: stake sizing comes from the measured historical performance of the signals behind each pick — picks backed by signals with strong live win rates get 2u or 3u, standard plays get 1u. Star ratings and units move together because they're derived from the same data, not from how loud the take is.
Frequently asked questions
How much money is 1 unit?
Whatever 1% of your betting bankroll is. With a $1,000 bankroll, 1u = $10. The dollar amount is personal; the percentage discipline is universal.
Is flat betting better than variable staking?
Flat betting (everything 1u) is the best default and beats emotional sizing every time. Variable staking only adds value when stake differences reflect measured edge differences, not gut feel.
What's a good monthly result in units?
Serious long-term bettors are thrilled with +5 to +15u a month on meaningful volume. Anyone promising +50u months is selling variance as skill.
