Fit3D, Inc | 29 followers on LinkedIn. We use the power of body dimensions to personalize digital journeys. | We believe that the dimensions of the human body hold untapped potential. When analyzed individually, a user's body dimensions can uncover health and wellness information, help her shop for the right clothing size or even the right brand to best fit her body. One day, with the partnerships we are forging, the world will automatically adjust to the dimensions of her unique body.
