Use our AI body shape calculator to determine your body type and measurements. Get personalized insights to help you reach your ideal physique today.


Shoulder width, waist circumference, and hip measurement are the numbers that map how your body actually distributes weight and responds to a calorie deficit. Someone with a wider hip-to-waist ratio has different macro priorities than someone who carries mass at the midsection: higher protein targets, a lower carb ceiling, adjusted fat thresholds. A 1,500-calorie template written for a different build ignores all of that. CheckMyMeal AI body shape calculator reads your shape result and builds targets around your unique physiology.
Enter your shoulder width, waist, and hip circumference into the calculator for body shape, and the tool identifies which category fits your proportions. Each category carries a different fat distribution pattern, and that pattern is what shapes your calorie math.
Pear-shaped bodies tend to store fat in the hips and thighs and respond well to moderate carb intake with higher protein. Apple-shaped bodies that carry more mass around the midsection often benefit from a lower carb ceiling and adjusted fat targets. Rectangle proportions, where shoulder, waist, and hip measurements run close together, usually call for a higher overall calorie target to support muscle development.
The body shape type calculator result is the input. What CheckMyMeal does with it is the output that actually moves the needle. Knowing your category without a plan attached to it gets you nowhere. Knowing it with one means your first week of tracking has a direction.
The body shape calculator for women and men built into CheckMyMeal already knows your proportions, so when you snap a photo of that bowl, the AI cross-references the portion estimate against targets that were built for your specific build. Someone whose body shape calculator measurements show a wider waist-to-hip ratio gets a higher protein floor and a tighter carb window than someone with narrower proportions. The logging takes 15 seconds. The math is already done. That Tuesday lunch stops being a source of stress and becomes just lunch.
The AI body shape calculator gives you a category. CheckMyMeal turns that category into a metabolic profile. From that point, the food tracking runs on the same logic. You don't search a database for grilled chicken breast at 180g and then argue with yourself about whether the portion was closer to 150. You take a photo, and CheckMyMeal's AI estimates the portion and updates your daily totals against the metabolic profile tied to your shape data.
Say it aloud if your hands are full — voice logging works the same way. The body shape calculator AI and the food tracker share the same data layer, which means your targets are never static. They move as your body does.

Enter your measurements, get your body type, and snap your first meal in under 15 seconds. CheckMyMeal syncs with Apple Health so your calorie targets shift automatically as your activity does. Your shape data is already there — let the AI calculator for body shape work with it.
