If you want to learn how big or how small a 33 inch waist is for your height, gender, build, and body fat level, then you're in the right place.
Before we begin, though, make sure that you know how to measure your waist circumference correctly so that you can get the most accurate data.
You can also see how your waist compares by checking out the articles below.
Is a 33 inch waist big for a woman?
Is a 33 inch waist fat for a woman? No, a 33 inch waist isn't extremely fat for a woman, but it's definitely not small, either. Indeed, health experts note that if you're a woman with a 33″ waist, then you're at a high risk for health problems like diabetes and cardiovascular disease. 
So, in the majority of cases, while a 33 in waist size might not look fat, it's still too big for a woman to live in optimal health.
The good news is that it's only too big by a couple of inches (anything under 31.5 inches is considered low risk).
You can lose belly fat by decreasing your calorie intake and increasing your activity level. Doing this will put your body in an energy deficit, which is a prerequisite for successful weight loss.
Is a 33 inch waist small for a man?
Based on American anthropometric data, a 33 inch waist is smaller than average for a man by nearly 8 inches. Some people may consider a 33 inch waistline to be a medium size, while others would say that it's definitely small.
Either way, it's highly unlikely that your 33 inch stomach is putting your health at risk since scientists recommend that men keep their waist below 35 inches to maintain good health. 
As you'll learn in just a moment, your body composition also influences how healthy a given waist size is.
How about a 33.5 inch waist?
While not absolutely tiny, a 33.5 inch waist is still far smaller than average and below the cut-off point for being considered low risk for various chronic diseases.
If you're well over 6 feet tall and have a large build, then you might naturally have a 33.5 inch waist or a 33.6 inch waist without having much body fat.
Of course, some people with smaller builds also have a 33.5 inch waist, in which case it's likely that a larger proportion of their midsection consists of fat mass rather than bone mass.
What does a 33 inch waist look like?
What does a 33 inch waist look like exactly? A 33 inch waist will look normal and healthy for the vast majority of men and, if anything, slightly on the slim side. For most women, however, a 33 inch waist will look bigger—too big, in many cases—but not necessarily outright fat.
The reason that it's recommended for women to keep their waists below 31.5 inches is that having a large waist circumference is an indicator of having excessive amounts of visceral fat, which is more dangerous than subcutaneous fat. 
Note the emphasis of the word indicator. If you have a 33″ waist due to having well-developed abs and obliques, then it's unlikely that health experts would declare your waist too big.
Muscle mass and fat tissue are not the same thing. You're much better off having a muscular and somewhat lean 33 inch stomach than you are having a 33 inch waist of mainly fat and minimum muscle.
Of course, women who have toned abs are unlikely to have a 33 inch waist, so this advice mainly applies to men, for whom a 33 in waist, in and of itself, is no cause for concern.
Conclusion: Is it ok to have a 33 inch waist?
Health isn't measured by inches on the tape measure. Yet, that doesn't mean that certain circumference measurements can't be used to gauge your current and predict your future health status.
As mentioned, scientific research shows that a 33 inch waist is a couple of inches too big for a woman (this may not be the case if you're 6 feet tall, for example).
On the other hand, having a 33 inch waistline as a man is fine and not something that you should worry about. Indeed, many people would say that a 33 inch waist is slim for males or, at the very least, a medium measurement.
Of course, it's entirely possible to have a 33 in waist and still be unhealthy due to other factors. Nonetheless, the size of your waist remains a good indicator of your health status and risk for certain chronic diseases.
