Dating age rule · 18+ only
The half-your-age-plus-7 rule is a folk guideline, not legal, medical or relationship advice. Results are for reference only. See our Terms and disclaimer.
How the dating age rule is calculated
The rule uses two short formulas. The minimum suggested age is your age divided by two, plus seven (rounded up to a whole year when needed). The maximum is your age minus seven, doubled.
For example, at 30 the suggested range is 22 to 46; at 32 it is 23 to 50; at 40 it is 27 to 66. When the formula produces a minimum below 18, this calculator shows 18 instead — all ages discussed on this site are adults.
The rule is a folk guideline that circulates socially, not a scientific or legal standard. Our role explainer covers where it came from and what critics say about it.

Dating Age Rule Calculator
This dating age rule calculator applies the half your age plus 7 formula to any adult age and can also check whether a specific partner age falls inside the suggested range. If you would rather work it out on paper, a half your age plus 7 calculator is just the two steps above: divide by two and add seven for the minimum, subtract seven and double for the maximum.
About the rule
What is the half your age plus 7 rule?
It is a folk guideline for dating age ranges. Take your age, divide it by two, and add seven — that gives the suggested minimum partner age. Subtract seven from your age and double it for the suggested maximum. It circulates as a social rule of thumb, not a scientific or legal standard.
Where did the half your age plus 7 rule come from?
The formula is commonly traced to early twentieth-century print, where it appeared as a humorous maxim rather than serious advice. It spread through popular culture over the following decades and now circulates widely as shorthand in discussions about age gaps between adults.
What is an appropriate age to date?
There is no single appropriate age to date; views differ across cultures, families and individuals. What is broadly consistent is that dating decisions belong to adults, and this site only discusses ages 18 and above. The half-your-age-plus-7 rule is one informal benchmark people use, not a standard.
What are the age limits for dating?
Legally, rules about ages and relationships vary by jurisdiction, and this site does not give legal advice. Socially, the half your age plus 7 formula is the most cited informal limit: minimum = your age ÷ 2 + 7, maximum = (your age − 7) × 2, computed for adults. Treat it as shorthand, not authority.
