Abstract: A modular growth chart assembly includes a growth chart module, one or more picture frame modules removably attached to a first side of the growth chart module, and at least one decorative frame module removably attached to the a second side of the growth chart module opposite of the first side. The growth chart module extends along a vertical height from a bottom end to a top end. The growth chart module includes hash marks disposed along its vertical height for measuring height, for example, of a child. Photos of the child can be implemented with the picture frame modules for adapting the growth chart assembly to a particular user or child. With the modular growth chart assembly, a user may substitute the decorative frame module to adapt the growth chart assembly along with a child's changing preference or interest.
