Increasing the sample size makes the distribution narrower

Increasing the sample size increases the area under the sampling distribution curve

Explanation:
Detailed explanation-1: -As the sample sizes increase, the variability of each sampling distribution decreases so that they become increasingly more leptokurtic. The range of the sampling distribution is smaller than the range of the original population.
Detailed explanation-2: -Increasing the sample size always makes it more likely to find a statistically significant effect, no matter how small the effect truly is in the real world. In contrast, effect sizes are independent of the sample size. Only the data is used to calculate effect sizes.
