Is there a limit on the number of individuals that I can add to Family Tree Builder?

Unlike the Family Site, where there is a limit on the number of individuals you can have in your tree,
(250 individuals for the Basic plan, 2500 individuals for the Premium plan, and an unlimited number for the PremiumPlus plan), There is no limit in Family Tree Builder.

Even if you have a Basic site, you can have as many individuals as you like in your Family Tree Builder project.

Keep in mind that when you publish the tree to the Family Site, only 250 individuals will be published.
