What is DNA Painter?

DNA Painter is a web-based tool designed to make chromosome painting accessible to the average person.

Chromosome painting is a technique that lets people visually represent and map segments of their DNA. It can show which parts of your DNA come from different ancestors or family lines.

DNA makes interpreting DNA results easy. Jonny Perl, a UK-based genealogist, DNA enthusiast, and web developer, created it.

It is an award-winning software that allows the user to:

  • Visualize their direct ancestry line
  • Map DNA segments to ancestors
  • Ascertain how they are related to a DNA match
  • Identify unknown ancestors using matches

Introduction to DNA Painter

DNA Painter is a tool used for chromosome mapping or DNA painting. It simplifies DNA results visually, providing a picture of a user's ancestry.

It is NOT a genetic test. It reads segmented data that are then turned into a visual relationship chart of the user’s relatives.

Raw DNA data may be obtained from genetic testing kits supplied by various companies, such as:

According to its website, DNA Painter does not endorse nor is it affiliated with any DNA testing company.

Where is DNA Painter Used?

Interpreting the results of an autosomal DNA test can be challenging. DNA Painter makes this easier by providing a platform where the user can:

  • Thoroughly assess what they already know about their ancestry by importing or building a family tree
  • Make use of DNA matches to determine relationships with the use of interactive tools
  • Utilize chromosome mapping to envision actual DNA segments shared with other matches and determine inheritance from other ancestors found in a user’s tree

Family history enthusiasts and genealogists mostly use DNA Painter.

How does DNA Painter Work?

DNA Painter allows users to “paint” individual DNA segments, differentiating maternal and paternal copies of a specific chromosome.

Once a particular segment has been painted, the user can easily see matches from either maternal or paternal sides. If the chromosomes match and in the exact location, the user is related to that match via the same family line.

How to Get Started on DNA Painter

  1. Depending on what you want to do, you can create an Ancestral Tree or do a Chromosome Map.

The DNA Painter interface is very intuitive and easy to understand and navigate. If you're new to chromosome mapping, there's a How-to video that can help.

DNA Painter Tools

At the top of the DNA Painter dashboard, there are three tools available to the user. This allows DNA visualization in a number of ways. These include:

1. Family Tree Fan Chart

Using a Family Tree Fan Chart, users can visualize their family tree. This can be done by:

  • Manual data entry
  • Uploading a GEDCOM file obtained from another family tree service

Users can customize colors for easy labeling and tracking. Preset colors are also available.

2. Shared cM Project Tool

Users simply have to input a DNA length (in centimorgans) they share with their matches from other sites. Using these data, DNA Painter can make a family tree.

Using a shared cM tool, users can:

  • Refine their family tree
  • Identify relationships that aren’t genetically possible
  • Find common ancestors shared with matches

Blaine Bettinger is the man behind the shared cM tool. He is an expert in using DNA to trace family history.

3. Chromosome Mapping

Chromosome Mapping allows users to view their chromosomes using a color-coded chart. This chart shows whether a segment came from the maternal or paternal side.

Using chromosome mapping, users can:

  • See where their specific traits like hair color, eye color, or mental ability originated
  • Perform genetic genealogy research on both maternal and paternal lineages

DNA Painter Costs

DNA Painter’s basic features are free to use. A free account allows a user to:

  • Review one profile

  • Make up to 50 profiles
  • Create a family tree with unlimited generations
  • Create and test unlimited family trees
  • Do bulk uploads of information 

Subscription prices are as follows:

  • $30 for six months
  • $55 for an entire year

  • Provides the ability to generate and test their theories about their ancestry
  • It can be used with many different kinds of DNA tests


  • Presence of a steep learning curve for first-time users
  • User interface and terms can be confusing at first
  • Works best with DNA test results of several known relatives

DNA Painter Review: Is It Worth It?

DNA Painter is a tool that isn't meant for everyone. However, genealogists, DNA enthusiasts, and those who wish to dig deeper into their ancestry can benefit from using DNA Painter's software.

Those who want to "look around" can do so with a free account. There is no need to jump into a subscription right away. However, with six-month or 12-month options, subscriptions don't force users to stick around for a long time.

DNA Painter is an excellent tool for those wanting to know more about their ancestry.
