The width of your short strangle — the distance between your call and put strikes — determines your premium, probability of profit, and risk exposure. Get it right and you have a high-probability income trade. Get it wrong and you're either not collecting enough premium to justify the risk or getting tested constantly.

Defining Strangle Width

Strangle width is the gap between your short call strike and short put strike.

Example: Stock at $100

  • Narrow strangle: Sell $103 call / $97 put (width: $6, 6% of stock)
  • Standard strangle: Sell $107 call / $93 put (width: $14, 14% of stock)
  • Wide strangle: Sell $112 call / $88 put (width: $24, 24% of stock)

    • The Tradeoffs

    | Width | Premium | Probability of Profit | Risk When Tested | Management Ease | Narrow (5-8%)HighLower (~55-60%)HigherHarder Standard (10-16%)ModerateMedium (~65-72%)ModerateModerate | Wide (18-25%) | Low | Higher (~78-85%) | Lower | Easier |

    There's no free lunch. Wider strangles win more often but pay less per win. Narrower strangles pay more per win but lose more often. Over time, the expected returns converge — the question is which tradeoff matches your trading style.

    Delta-Based Strike Selection

    Most experienced traders use delta rather than percentage distance to select strikes:

    16-delta (≈1 standard deviation):

  • The most common choice for income traders
  • ~68% probability of both options expiring OTM
  • Collects meaningful premium
  • Tested about once in three trades

    • 10-delta (≈1.3 standard deviations):

  • Higher probability (~80% of both expiring OTM)
  • Less premium collected
  • Tested less frequently
  • Better for traders who prefer fewer adjustments

    • 25-delta:

  • Aggressive — higher premium but lower probability
  • Tested frequently
  • Requires active management
  • Better for experienced traders comfortable with adjustments

    • 30-delta:

  • Essentially a narrow strangle, almost ATM
  • Very high premium, low probability
  • Gets tested constantly
  • Almost a short straddle with a gap in the middle

    • How IV Affects Width Decision

    In high-IV environments, you can sell wider and still collect decent premium:

    Stock at $100, 30-day expiration:

    | IV Level | 16-delta Call Strike | 16-delta Put Strike | Width | Credit | 20%$104$96$8$1.20 35%$107$93$14$2.40 | 55% | $112 | $88 | $24 | $4.20 |

    At 55% IV, the 16-delta strikes are far OTM, giving you a wide profit zone AND a fat premium. This is why high-IV environments are ideal for selling strangles — you don't have to sacrifice width for premium.

    Matching Width to Your Account

    Position sizing affects your optimal width. A $25,000 account can't afford to sell 25-delta strangles on $500 stocks — the margin requirement is too large relative to the account.

    Guidelines:

  • Account < $25,000: Stick to 10-16 delta on stocks under $100
  • Account $25,000-$100,000: 16-delta on stocks under $200
  • Account > $100,000: Full flexibility on delta and stock selection

    • Width by Strategy Goal

    Asymmetric Strangles

    You don't have to sell both sides at the same delta. If you're slightly bullish, you might:

  • Sell a 10-delta put (further OTM, less risk on downside)
  • Sell a 20-delta call (closer, more premium from the upside)

    • This tilts the strangle toward your directional bias while keeping the core structure intact.

    Backtesting Width

    Historical data consistently shows:

  • 16-delta strangles offer the best risk-adjusted returns over long periods
  • 10-delta strangles have higher win rates but lower total returns due to small individual wins
  • 25-30 delta strangles generate the most premium but suffer larger drawdowns

    • The 16-delta sweet spot works because it balances premium collection with a manageable frequency of losing trades.
