What is a Family Tree Calculator?
A Family Tree Calculator is a digital tool that helps you estimate the size and structure of your family by inputting specific family relationships. Instead of drawing complex diagrams or manually adding members, you can instantly see how many people are included in your immediate and extended family.
Our calculator focuses on four key family elements:
- Parents – Your direct ancestors in one generation above you.
- Siblings – Brothers and sisters who share the same parents.
- Children – Your direct descendants in the next generation.
- Grandchildren – The generation after your children.
By combining these inputs, the calculator provides a quick snapshot of your family size and how many generations are represented.
