This is a question for which there is no standard answer.

Each strike price call or put option in the option has a corresponding delta value. This delta value simply refers to how much the option price of the current strike price will change if the stock index changes by 1 yuan. .

For complete hedging, if delta is 0.5, then because the multiplier of stock index options is 100 and the multiplier of stock index futures is 300, one lot of stock index futures needs to be allocated to 6 lots of stock index options.

But! delta is not 0 most of the time. Therefore, there is no standard answer to this question and it needs to be calculated based on specific circumstances.
