Is 170 lbs overweight for a woman at 5'10"?
No — 170 lbs is within the healthy range for 5'10" (for a woman).
At 170 lbs (77.1 kg) and 5'10" (177.8 cm) for a woman, the BMI is 24.4 — normal weight.
Public-health guidelines place the ideal weight for 177.8 cm tall adults at 129–174 kg, equivalent to a BMI between 18.5 and 24.9.
What the numbers mean for you
You have 4 lbs (1.9 kg) of headroom before crossing into overweight (BMI 25 = 174 lbs (79.0 kg)).
Your BMI band midpoint is BMI 21.7 (151 lbs (68.6 kg)), often used as the "most protective" reference in cohort studies.
Timelines assume ~7,700 kcal per kg of body fat. Real progress varies with muscle mass, adherence, and medications.
What this means
Within this range, body composition matters more than the exact number — muscle mass and waist circumference become the better health signals.
Waist matters more than the scale
Two people can share the same BMI and have very different metabolic risk. For that reason, waist circumference is now considered a stronger predictor of cardiometabolic disease than BMI alone.
- Waist-to-height rule: keep your waist under half your height — that means below 89 cm (35") at 177.8 cm.
- Absolute cutoff for women: waist under 80 cm (31.5") is associated with meaningfully lower risk of type 2 diabetes and cardiovascular disease.
- Higher-risk zone: waist above 88 cm (35") — this is where risk climbs sharply regardless of BMI.
For women at 5'10"
BMI uses the same formula for both sexes, but health interpretation differs. Women typically carry a higher percentage of body fat at the same BMI than men. A waist circumference under 35 inches (88 cm) lowers cardiometabolic risk independent of BMI.
