What is considered obese is a body mass index of 30.0 or higher. BMI is calculated from your height and weight, and doctors use it as a starting point to sort weight into categories: under 18.5 is underweight, 18.5 to 24.9 is a healthy range, 25.0 to 29.9 is overweight, and 30.0 and above is obesity. For most adults, obesity begins somewhere between 145 and 240 pounds depending on height. That single number does not tell your whole story, but it is the number almost every insurance policy, surgical program and treatment guideline still runs on.
Below is what each threshold actually means, what it looks like in pounds at your height, and where BMI stops being useful.
What Is Considered Obesity?
Obesity is a chronic medical condition, not a description of willpower. It means your body carries enough excess fat to raise your risk of other health problems, and it is diagnosed rather than judged. The clinical definition sits at a BMI of 30 or above, and doctors divide it into three classes:
| Class | BMI range | Also called |
| Class 1 | 30.0 to 34.9 | Mild obesity |
| Class 2 | 35.0 to 39.9 | Moderate obesity |
| Class 3 | 40.0 and above | Severe, extreme or morbid obesity |
Being clinically obese simply means a doctor has recorded a BMI in one of those bands. It is a starting point for care, and for many people it opens the door to treatment options that are not available at lower BMIs.
What BMI Is Considered Obese?
A BMI of 30.0 is the cutoff. Anything at or above that number is obesity, and anything below it is not, no matter how the number was reached. A BMI of 29.9 is classified as overweight rather than obese, which is why a two pound difference can change what an insurance company will approve.
To calculate it yourself: divide your weight in pounds by your height in inches squared, then multiply by 703. A 5’6″ person weighing 190 pounds has a BMI of 30.7, which lands in Class 1 obesity.
BMI thresholds matter most when you are exploring surgery, since BMI requirements for bariatric surgery are written directly into insurance policy language. The specific cutoffs differ by procedure, which is why BMI for gastric sleeve and BMI for gastric bypass are worth checking separately.
What Weight Is Considered Obese in Pounds?
There is no single weight that makes someone obese. A 5’2″ adult crosses into obesity at 164 pounds, while a 6’2″ adult does not cross it until 234 pounds. Height and weight have to be read together, which is exactly what BMI does.
The one thing worth knowing is that the scale alone can mislead you in both directions. A muscular person can post an obese BMI with very little body fat, and someone with a normal BMI can carry high internal fat. That second pattern has a name, and it is covered in more depth in our guide to skinny fat body composition.
What Is Considered Obese by Height: 4’11” to 6’3″ Chart
This chart shows the weight at which obesity begins (BMI 30) and where severe obesity begins (BMI 40) for each height.
| Height | Obese at (BMI 30) | Severely obese at (BMI 40) |
| 4’11” | 149 lb | 198 lb |
| 5’0″ | 154 lb | 205 lb |
| 5’1″ | 159 lb | 212 lb |
| 5’2″ | 164 lb | 219 lb |
| 5’3″ | 169 lb | 226 lb |
| 5’4″ | 175 lb | 233 lb |
| 5’5″ | 180 lb | 240 lb |
| 5’6″ | 186 lb | 248 lb |
| 5’7″ | 192 lb | 255 lb |
| 5’8″ | 197 lb | 263 lb |
| 5’9″ | 203 lb | 271 lb |
| 5’10” | 209 lb | 279 lb |
| 5’11” | 215 lb | 287 lb |
| 6’0″ | 221 lb | 295 lb |
| 6’1″ | 227 lb | 303 lb |
| 6’2″ | 234 lb | 312 lb |
| 6’3″ | 240 lb | 320 lb |
These numbers are identical for men and women, because BMI does not adjust for sex. The interpretation is where the difference shows up.
What Is Considered Obese for a Woman?
For women, obesity starts at the same BMI of 30, but women naturally carry more essential body fat than men at every BMI. A woman and a man with identical BMIs of 32 will usually have different amounts of fat and different risk profiles.
Hormonal shifts complicate the picture further. Weight distribution changes during perimenopause, and conditions such as PCOS and thyroid disorders can make weight gain far harder to reverse. If your weight has climbed despite consistent effort, there may be a medical reason behind it worth investigating.
What Is Considered Obese for a Man?
Men also cross into obesity at a BMI of 30. The clinical concern for men tends to be where the fat sits rather than how much there is, because men store more of it around the abdomen and around the organs. That deep abdominal fat drives more metabolic damage than fat stored under the skin, a distinction explained in visceral fat vs subcutaneous fat.
What Is Considered Morbidly Obese?
Morbid obesity means a BMI of 40 or higher, or a BMI of 35 or higher combined with a serious weight related health condition. The term is older clinical language and many surgeons now say severe obesity instead, but insurance forms still use it.
At a BMI of 40, a 5’4″ adult weighs roughly 233 pounds and a 5’9″ adult roughly 271 pounds. This is the range where bariatric surgery for severe obesity usually becomes the recommended option rather than one choice among several.
What Is Considered Severely Obese, Extremely Obese or Class 3 Obesity?
These four terms all describe the same thing: a BMI of 40 or above. Severe obesity, extreme obesity, morbid obesity and Class 3 obesity are interchangeable labels for the top band. Some programs add an unofficial Class 4 for BMI above 50 and Class 5 for BMI above 60, because surgical planning and anesthesia risk change at those levels.
What Body Fat Percentage Is Considered Obese?
Body fat percentage measures what BMI only estimates. The commonly used obesity thresholds are 25% or higher for men and 32% or higher for women, though different organizations set them a few points apart.
Body fat is the better measure of the two, but it needs a DEXA scan or a bioimpedance device to read accurately, so BMI remains the default in clinics and insurance policies. If you are tracking composition rather than scale weight, our guide on how to reduce body fat percentage covers what actually moves it. Older adults should also read about sarcopenic obesity, where high fat and low muscle occur together and BMI hides both.
What Waist Circumference Is Considered Obese?
Waist measurement flags abdominal obesity, and it catches risk that BMI misses. The thresholds are 40 inches or more for men and 35 inches or more for women who are not pregnant.
Measure at the top of your hip bone, after breathing out, without pulling the tape tight. A high waist measurement alongside a normal BMI still signals elevated metabolic risk, and it often shows up early in insulin resistance.
What BMI Is Considered Obese in Pregnancy?
BMI in pregnancy is based on your weight before you conceived, not your current weight. A pre pregnancy BMI of 30 or higher is classified as obesity and changes how much weight gain is recommended during the pregnancy, typically 11 to 20 pounds rather than the usual 25 to 35.
Timing matters if surgery is part of your plan, and our article on pregnancy after bariatric surgery explains the recommended waiting period.
What Is Considered Childhood Obesity?
Children are not assessed against adult numbers. A child’s BMI is compared to other children of the same age and sex, and obesity is defined as a BMI at or above the 95th percentile. Severe childhood obesity begins at 120% of that 95th percentile value.
What Is Considered a Serious Comorbidity With Obesity?
A serious comorbidity is a health condition caused or worsened by excess weight, and it is what allows a BMI of 35 to qualify for surgery when a BMI of 40 would otherwise be required. The conditions that count most often are:
- Type 2 diabetes, addressed in which bariatric surgery is best for type 2 diabetes
- Obstructive sleep apnea, covered in bariatric surgery for sleep apnea
- High blood pressure and high cholesterol
- Fatty liver disease
- Severe joint disease, GERD and metabolic syndrome
The full range of what excess weight does to the body is laid out in health issues with being overweight.
Knowing your number is the easy part. Deciding what to do with it is where a specialist helps. Depending on where your BMI falls, that might mean a gastric sleeve, a gastric bypass, a SADI-S procedure, a gastric balloon or a non-surgical medical weight loss program if surgery is not the right fit yet. BodEvolve sees patients across Dallas, Arlington, Richardson and Texarkana. Book a consultation to find out which category you fall into and what your options actually are.
