AncestryDNA vs. MyHeritage: Which DNA Test is Best in 2026?
For anyone interested in tracing their family roots, choosing the right DNA test and genealogy platform is a crucial first step. In 2026, AncestryDNA and MyHeritage stand out as two of the most popular and powerful tools available.
1. Database Size and Record Strengths
The size of a company's database directly impacts your chances of finding DNA matches.
AncestryDNA leads the industry by a massive margin, boasting a database of over 22 million sets of DNA results.
This enormous community means you have a better chance of finding relatives, especially if your ancestors have deep roots in the United States.
Ancestry provides a more comprehensive array of North American records, such as the 1950 U.S. Census and Freedmen's Bureau archives.
MyHeritage DNA has a significantly smaller database, with over 6.6 million DNA results.
Despite the smaller size, MyHeritage shines when it comes to tracing European ancestry.
MyHeritage has strong international representation, particularly with Middle Eastern, Jewish, and Scandinavian populations, making it a powerful choice if you are looking for relatives overseas.
2. Testing Methods and 2026 Technology Updates
How you take the test and how it is processed varies between the two companies.
With AncestryDNA, you collect your DNA sample by spitting saliva into a tube.
AncestryDNA conveniently prepays the return postage for mailing in your sample.
MyHeritage asks you to rub a swab against the inside of your cheek, which some users prefer over a saliva sample.
However, MyHeritage requires you to pay for your own return postage to the laboratory.
In a major technological shift for 2026, MyHeritage has transitioned its tests to Whole Genome Sequencing (WGS), sampling around 3 billion base pairs rather than using the older genotyping array.
This new WGS method opens up exciting possibilities for more accurate matches and improved reports into ancestral origins.
AncestryDNA estimates a six to eight week wait to process your results, while MyHeritage estimates a slightly faster turnaround of three to four weeks.
3. Ethnicity Estimates and Geographic Regions
Both services provide detailed breakdowns of where your ancestors originated by matching your DNA to global population groups.
AncestryDNA breaks the world down into over 2,600 distinct ethnic regions.
Ancestry is highly regarded for its detailed ethnicity accuracy and frequent updates that automatically refine your ethnic breakdown over time.
MyHeritage covers over 2,000 geographic regions.
While MyHeritage boasts detailed breakdowns for European and Middle Eastern populations, some reviewers note that their ethnicity matching can seem inconsistent compared to other ancestry DNA sites.
4. Genealogy Tools and Unique Features
If you want to build a family tree, both companies offer fantastic tools, though advanced features often require subscriptions.
Ancestry allows you to view your shared matches without needing a paid subscription, which is highly beneficial for users on a budget.
Ancestry's system integrates seamlessly with its historical documents, offering “shaky leaf” hints that link your listed ancestors to official records.
MyHeritage, unfortunately, requires a paid subscription to view shared matches.
A major advantage of MyHeritage is that it lets you upload your raw DNA data from other testing companies for free, which broadens your chances of finding new relatives.
MyHeritage also stands out with a creative suite of AI-based tools that allow you to enhance, colorize, and animate old family photographs.
Conclusion: Which Should You Choose?
Your choice largely depends on your priorities.
