Body Frame Size and Why It Changes Ideal Weight
Small, medium and large frames carry weight differently.
What frame size is
Frame size describes bone structure. A common quick estimate compares your height with wrist circumference.
How it affects weight
People with larger frames may sit toward the upper end of healthy weight ranges, and smaller frames toward the lower end. The effect is a few kilograms, not a licence to ignore other measures.
Practical use
Use frame size to choose a target within a healthy range, then confirm it with waist size and fitness.
