(CBS Local) — The secret to a happy marriage may be in your height, according to a study.

Women tend to prefer taller men and that might be a good thing if they want to have a great marriage. The study found that women who have tall husbands tend to be happier. In the study, researchers surveyed 8,000 participants, and found a correlation between the husband’s height and the wife’s happiness.

Researchers say the more inches separating you height-wise, the better your relationship will be.

However, the study found this is only a factor for the first 18 years of marriage. After 18 years, height doesn’t matter.
