Find charts and tools for determining a person's ideal healthy weight on sites such as Rush.edu, CDC.gov, Calculator.net, HealthDiscovery.net and WebMD.com, as of April 2015. These charts factor in a person's age, gender and height to determine an ideal weight range.
One common system for determining someone's ideal weight is the Body Mass Index, which factors in gender, height and weight to come up with a numeric position on a chart. This method does not take other health conditions into consideration. Anyone using this chart should discuss the results with a doctor to ensure that the readings are accurate and healthy.
