How Much Should I Weigh?

“What’s the right weight for me?” is a question that many people have. There isn’t a single “perfect” number that suits everyone, in actuality. A number of variables, including your age, sex, height, body composition, and general health, affect your ideal weight.
In general, a BMI of 18.5 to 24.9 is regarded as healthy. However, because BMI doesn’t account for muscle, bone density, or fat distribution, it doesn’t provide a complete picture. Athletes, for instance, can be extremely healthy despite having a higher BMI.
Choose a weight that makes you feel strong, active, and at ease rather than aiming for a specific number. Prioritise stress reduction, healthy eating, regular exercise, and adequate sleep. It is common for your body to naturally settle into its healthiest range.
In short: the “right” weight is the one that supports your health and lifestyle—not just a number on a chart.

Age

Theoretically, an IBW shouldn’t be significantly influenced by age after the ages of 14–15 for girls and 16–17 for boys, when most people stop developing. Human males and females are actually predicted to lose 1.5 and 2 inches of height, respectively, by the time they are 70 years old. It’s crucial to keep in mind that lean muscle mass declines with age, making it simpler for people to gain excess body fat. While this is a natural process, there are ways to mitigate the effects of ageing, including maintaining a healthy diet, exercising, managing stress, and getting enough sleep.

Gender

Despite having a higher percentage of body fat by nature, women typically weigh less than men. This is due to the fact that muscle weighs more than fat and that men typically have larger bodies. In addition, women’s bone density is typically lower. Finally, men are typically taller than women.

Height

A person’s weight increases with height because taller people have more muscle mass and body fat. A male should weigh roughly 10–20% more than a female of the same height.

Body Frame Size

The measurement of ideal weight can also be significantly influenced by body frame size. Generally speaking, body frame sizes are classified as small, medium, or large boned. As seen below, it is determined by comparing a person’s wrist circumference to their height.

mall-boned (wrist size less than 5.5″) and under 5’2″

5.5″ to 5.75″ wrist size is considered medium boned.
Wrist size over 5.75″ and height between 5’2″ and 5’5″ are indicative of large bones.
Wrist size less than 6″ is considered small boned.
A wrist size of 6″ to 6.25″ corresponds to medium bonedness.
Wrist size over 6.25″ and height over 5’5″ indicate large bones.
A wrist size of less than 6.25 is considered small boned.
Wrist sizes 6.25″ to 6.5″ correspond to medium boned people.
Men’s wrist size over 6.5″ is considered large boned.

More than 5′ 5″
Wrist size 5.5″ to 6.5″ for small bones.
A wrist size between 6.5″ and 7.5″ is considered medium boned; a wrist size greater than 7.5″ is considered large boned.
Even at the same height, a person with large bones will naturally weigh more than someone with small bones, so body frame size can have an impact on metrics like IBW and BMI.

Healthy BMI Range

For both men and women, the World Health Organisation (WHO) recommends a healthy BMI range of 18.5 to 25. It is possible to determine a healthy weight for any given height based on the BMI range.

One often used metric for calculating IBW is BMI. In the medical field, it is frequently used as a rapid indicator of potential health issues. In general, a person’s risk of developing health issues like obesity, diabetes, heart disease, and many more increases with their BMI. It is currently the official metric for categorizing people according to various levels of obesity and is a tool used by physicians to warn their patients about possible health issues, particularly if there is a discernible progressive increase in their BMI.

Healthy BMI Range for Children

The aforementioned formulas are all intended for adults who are at least eighteen years old. Please refer to the Centres for Disease Control and Prevention’s (CDC) BMI charts for kids and teenagers. Depending on their age, children should keep their BMI in the 5th to 85th percentile, according to the CDC.

Limitations of our IBW calculator

All of the methods and formulas have limitations. The formulas cannot be extremely accurate for each and every person since they are intended to be as applicable to as many different types of people as possible. Only height and gender are taken into account in the formulas; physical disabilities, individuals at the extremes of the spectrum, activity levels, and muscle mass to body fat ratios—also referred to as body composition—are not taken into account. The results of our ideal weight calculator are not meant to be rigid standards that an individual must meet in order to be deemed to have a “ideal weight calculator.” Rather, they are meant to serve as a general guideline based on widely used formulas.
