What is the purpose of a golf ball fitting chart?

Golf ball fitting charts are used to determine the optimal ball type for a player's particular swing, based on input received from a questionnaire or the analysis of data from launch monitor technology. These charting tools factor variables such as swing, speed and compression against dimples, cover and core.

As of 2016, the technology on Bridgestone.com uses analysis of over 300,000 launch models to arrive at an estimation of the ball required for a player. The website asks a series of questions, such as average driver distance, score, shot shape and trajectory. Titleist provides 3-D models and questionnaires that are used to create comparison charts and recommendations.
