Ideal Weight (Body-Weight Formulas)
Devine, Robinson, Miller, and Hamwi formula estimates of a healthy weight for your height — planning references, not military standards.
Data updated: 2026-08-20 (verified vs primary service regulations)
Formula
Devine men: 50 + 2.3 kg per inch over 5 ft · (women: 45.5 + 2.3) — formulas differ slightly by method.
Healthy range
Formula-dependent; always pair with WHtR or body-fat %, since weight alone cannot judge composition.
Military & first-responder angle
Historical height-weight tables operated on the same idea; 2026 replaced them with WHtR. Treat ideal-weight outputs as context, not a standard.
Calculator
Healthy weight range for a height from the BMI 18.5–24.9 band — the band most accession screens sit within.
Result
About this calculator
Healthy weight range for a height, taken from the BMI 18.5–24.9 band that most accession screens sit within.
The formula
Range = BMI 18.5 and 24.9 solved for weight at your height.
Frequently asked questions
Q: Is this my target weight?
A: It is a reference band. Service height-weight tables and body-fat standards differ; confirm with a recruiter.
Q: Why the 18.5–24.9 band?
A: That band is associated with lower health risk and aligns with common accession screens.
Q: What if I am outside it?
A: A clinician looks at body-fat and fitness, not just the scale.
How to read the result
A healthy weight range comes from applying a BMI band to a given height, which means it inherits every limitation of BMI. The band is deliberately wide, because within it the same weight can represent very different body compositions. For most people the useful reading is the direction of travel rather than the exact landing point inside the range.
The accession context is separate and stricter. Services publish their own applicant ranges, and clearing a healthy-weight band does not guarantee that an accession range is met. Where the two disagree, the service figure governs the application. Use this range for planning a sustainable change over months, and confirm the applicable limits with a recruiter before building a timeline around any number.
