The surrogate BMI calculator.
Find your BMI, then see how it reads against the ranges programs actually screen on — under 35 for surrogates, 18 to 30 for egg donors. A number, not a verdict.
Starting an application, a screening call, or a clinic medical review.
Surrogate screening (under 35) and egg donor screening (18–30) in both unit systems.
Your BMI, its standard adult band, program fit, and the target weight at the ceiling.
Enter height and weight.
BMI calculator
Check your BMI against program screening ranges
Enter height and weight to see your BMI, the standard adult band it falls in, and how it reads against the published Patriot Conceptions screening range. BMI is one screening input — never the whole decision.

What BMI does and does not decide
- BMI is a screening filter, not a health verdict. It does not account for muscle mass, body composition, or where weight is carried.
- Individual IVF clinics set their own limits and some are stricter than the agency range. The clinic your match uses has the final say.
- Pregnancy history, blood pressure, prior deliveries, and medication history weigh at least as heavily as BMI in a screening decision.
- A BMI near the edge of the range is worth applying with — the medical review looks at the whole picture.
This calculator is a planning aid, not medical advice, and not an eligibility decision. Final screening is completed by the IVF clinic and the program medical team.
One number, in context.
It is checked early because it is cheap to check. A BMI under 35 moves an application forward; it does not by itself qualify anyone, and everything else in the medical file still gets reviewed.
Individual IVF clinics set their own transfer criteria. A carrier who clears the agency range can still be asked by a specific clinic to reach a lower number before transfer.
At least one prior healthy birth, an uncomplicated delivery record, and stable blood pressure carry more weight in a screening decision than a BMI a point or two either side of the line.
A number above 35 is not a closed door.
The calculator shows the weight that lands on BMI 35 at your height, so the distance is concrete instead of vague. Applicants who reach the screening range and re-apply are considered on the same terms as anyone else.
If your BMI is close to the line, apply now rather than waiting. Screening looks at the whole medical picture, and a coordinator can tell you where you actually stand faster than a calculator can.
