Ideal or Healthy Weight Calculator

Healthy Weight Calculator Sign

This calculator will help you to calculate the ideal amount you should weigh based on your gender, height, and body-frame type.

Plus, it will also tell you how many pounds or kilograms you will need to lose or gain to achieve that ideal.

The calculations used in this calculator are based on the Hamwi Method, a formula developed by Dr. G.J. Hamwi.

What sets this formula apart from other similar formulas (Robinson Formula, Miller Formula, etc.) is that the Hamwi Method accounts for differences in body frames (small, medium, and large). Note that this formula is usually only recommended for adults who are at least 5 feet tall.

Selected Data Record:

A Data Record is a set of calculator entries that are stored in your web browser's Local Storage. If a Data Record is currently selected in the "Data" tab, this line will list the name you gave to that data record. If no data record is selected, or you have no entries stored for this calculator, the line will display "None".

To estimate your frame size, wrap your thumb and index finger around the opposing wrist. If your thumb and finger overlap, you have a small frame. If your thumb and finger barely touch, you have a medium frame. If your thumb and forefinger don't touch, you have a large frame.

Healthy or ideal weight:

This is the estimate of ideal amount you should weigh. No single calculator is capable of determining your exact "ideal," as none can account for your unique fat proportion, bone density, or muscle mass. However, just having an estimated target is better than having no goal at all. As long as you don't go below the safe level of calories per day (1,000-1,200 for women, 1,300-1,500 for men), common sense and a mirror will tell you when you've reached your own unique HW.

Help and Tools

Adjust Calculator Width:

Move the slider to left and right to adjust the calculator width. Note that the Help and Tools panel will be hidden when the calculator is too wide to fit both on the screen. Moving the slider to the left will bring the instructions and tools panel back into view.

Also note that some calculators will reformat to accommodate the screen size as you make the calculator wider or narrower. If the calculator is narrow, columns of entry rows will be converted to a vertical entry form, whereas a wider calculator will display columns of entry rows, and the entry fields will be smaller in size ... since they will not need to be "thumb friendly".

Show/Hide Popup Keypads:

Select Show or Hide to show or hide the popup keypad icons located next to numeric entry fields. These are generally only needed for mobile devices that don't have decimal points in their numeric keypads. So if you are on a desktop, you may find the calculator to be more user-friendly and less cluttered without them.

Stick/Unstick Tools:

Select Stick or Unstick to stick or unstick the help and tools panel. Selecting "Stick" will keep the panel in view while scrolling the calculator vertically. If you find that annoying, select "Unstick" to keep the panel in a stationary position.

If the tools panel becomes "Unstuck" on its own, try clicking "Unstick" and then "Stick" to re-stick the panel.
