Guidelines for a maximum weight for joining the Be The Match Registry ® have been established to help ensure donor safety .

The donor weight guidelines state that for people joining the registry, the maximum acceptable weight would be a person's weight associated with a body mass index (BMI) of 40*. To see the maximum weight (in pounds) for a given height (in feet and inches), see the chart below.

*BMI Formula: weight (lb) / height (in) 2 x 703. Calculate BMI by dividing weight in pounds (lbs) by height in inches (in) squared and multiplying by a conversion factor of 703.

Example: Weight = 150 lbs, Height = 5'5" (65")
Calculation: [150 ÷ (65) 2 ] x 703 = 24.96
