Frequently Asked Questions About 4-Generation Trees
How many people are in a 4-generation family tree?▼
In a direct pedigree line, a 4-generation tree has 15 direct ancestors (1 self + 2 parents + 4 grandparents + 8 great-grandparents). In an extended family tree including siblings, aunts, uncles, and cousins (like our Harrington Dynasty template), it typically ranges from 14 to 30+ individuals.
What is the difference between a family tree and a pedigree chart?▼
A pedigree chart strictly maps direct biological ancestors (parents, grandparents, great-grandparents), doubling at each tier without showing aunts, uncles, or cousins. A comprehensive family tree charts all collateral branches and spouses. Roots & Bonds lets you do both seamlessly on the same infinite canvas.
How does the canvas handle wide diagrams without cutting off text?▼
When you load the 4-generation template, our engine calculates the bounding box (approx. 1600px wide) and automatically adjusts the viewport scale (fitView) so the entire dynastic chart fits on your screen with 20% breathing padding. You can zoom in and pan freely.
