Family tree design is the process of visually organizing genealogical information to show how relatives are connected, typically using a chart, diagram, or digital tool. The best design depends on your audience, the amount of data, and whether you need a simple poster or an interactive research database.
What a Family Tree Actually Shows
A family tree is a diagram that maps kinship relationships. The most common format is a pedigree chart, which places an individual at the base (or center) and branches upward to parents, grandparents, and beyond. Descendant charts do the reverse: they start with an ancestor and fan out to children, grandchildren, and later generations. Some designs are hourglass-shaped, combining both ancestors and descendants for one focal person.
Beyond the classic tree, there are fan charts (semicircular or circular, often used for display), bowtie charts (showing both spouses’ ancestries), and wall charts (large-format prints). Each serves a different purpose: a fan chart is compact and decorative, while a descendant chart is better for tracking many branches.
Key Design Elements to Consider
Before choosing a tool, decide on these core elements:
- Direction of flow: Ancestors going up, descendants going down, or a combination.
- Information density: Names only, or also dates, places, and photos.
- Scale: A few generations for a gift, or hundreds of individuals for research.
- Format: Digital interactive, printable PDF, or physical poster.
For a standard pedigree chart, each person is represented by a box (or circle) with lines connecting to their parents. Color-coding branches (e.g., paternal side in blue, maternal in red) helps readability. If you include spouses, use a horizontal line to indicate marriage and a vertical line down to children—this is the most universally understood convention.
How to Choose the Right Software or Tool
Your choice of tool depends on your technical comfort and goals. Here are the main categories:
- Genealogy software: Programs like Family Tree Maker, Legacy, or Gramps are designed for research. They store sources, notes, and media, and auto-generate charts. Best for serious researchers.
- Online tree builders: Ancestry, MyHeritage, and FamilySearch offer free tree tools with collaboration features. They also suggest records and DNA matches, but your data lives on their servers.
- Graphic design tools: Canva, Lucidchart, and Microsoft PowerPoint allow custom layouts. You control every line and color, but you must manually enter all data—time-consuming for large trees.
- Specialized chart makers: Tools like Family Echo or DrawFamilyTree are simple and free, but limited in customization.
For a quick, clean result, online tree builders are easiest. For a one-time artistic poster, a design tool gives you full control. For long-term research, dedicated genealogy software is worth the learning curve.
Common Design Mistakes and How to Avoid Them
Many family tree projects fail because of avoidable errors:
- Cramming too much information: A 10-generation chart with full dates and places becomes unreadable. Limit text to what fits the medium.
- Ignoring marriage and remarriages: If an ancestor married twice, show both spouses and clearly mark which children belong to which union. Use dashed lines for step-relationships.
- Inconsistent naming: Use the same name format throughout (e.g., “John Smith” not “J. Smith” in one place and “John” in another).
- Forgetting to cite sources: Even for a family chart, note where you got each fact. This prevents future disputes.
A common misconception is that a family tree must be a literal tree shape. In reality, most professional genealogists use structured charts because they can expand without breaking the layout. The “tree” is a metaphor, not a design requirement.
Costs: Free vs. Paid Options
You can create a family tree entirely for free. FamilySearch is free (run by the Church of Jesus Christ of Latter-day Saints) and offers a collaborative tree. Ancestry and MyHeritage have free accounts, but viewing records and advanced chart options require subscriptions (typically $20–$40/month). Standalone software like Gramps is free and open-source; Family Tree Maker costs about $80–$100 for a one-time purchase.
For printed posters, costs range from $20 for a simple 11×17 print to over $100 for a large-format canvas. Professional designers charge by the hour, but you can achieve similar results with a template.
Privacy and Accuracy Concerns
Before publishing your tree online, consider privacy. Most platforms allow you to mark living people as private—they won’t appear in public searches. If you share a chart publicly, blur or omit birth dates for living relatives.
Accuracy is another issue. Online trees are notorious for copying errors. Always verify information against primary sources: birth certificates, census records, marriage licenses, or family Bibles. If you find conflicting dates, note both and explain the discrepancy in a comment or footnote.
Frequently Asked Questions
What is the best free family tree maker?
FamilySearch is the most robust free option because it includes record hints and a collaborative tree. For a simple, no-account chart, Family Echo is quick but limited. If you want full control, use a free trial of Canva or a blank Lucidchart.
How do I show half-siblings on a family tree?
Draw a horizontal line connecting the shared parent to the half-sibling’s other parent (if known). Use a dashed line for the half-sibling’s connection to the non-shared parent. Most software has a “half-sibling” option that automatically adjusts the layout.
Can I include adopted family members?
Yes. Use a dashed line for adoption and a solid line for biological relationships. Some charts use a double line to indicate adoption. Clearly label “adopted” or “biological” in the person’s notes to avoid confusion.
What is the difference between a pedigree chart and a family tree?
A pedigree chart shows only direct ancestors (parents, grandparents, etc.) for one person. A family tree typically includes siblings, spouses, and descendants. Pedigree charts are narrower and easier to fit on a page.
How many generations can I realistically show?
On a standard A4 or letter-size page, you can comfortably show 4–5 generations with names and dates. For 6–7 generations, use a fan chart or a large poster. Digital trees can show unlimited generations, but readability drops after about 8.
Should I use a circular or vertical layout?
Vertical layouts are easier to read and print. Circular fan charts are compact and visually striking, but they require special software and are harder to update. Choose vertical if you plan to add more people later.
