Wat is de BMI-calculator?
The BMI Calculator computes your Body Mass Index — a widely used screening tool that estimates body fat based on your height and weight. BMI provides a quick, accessible way to assess whether your weight falls within a healthy range, though it has important limitations. Developed by Belgian mathematician Adolphe Quetelet in the 1830s, BMI is calculated as weight (kg) divided by height squared (m²). The World Health Organization classifies BMI into categories: underweight (<18.5), normal (18.5-24.9), overweight (25-29.9), and obese (30+). This calculator accepts both metric and imperial measurements and provides your BMI with contextual health information. It also explains BMI's limitations and when other health metrics might be more appropriate.

Veelgestelde vragen
▶Wat is BMI?
BMI is een maat voor lichaamsvet op basis van lengte en gewicht. Het wordt berekend door gewicht (kg) te delen door lengte (m) in het kwadraat.
▶Wat is een gezond BMI-bereik?
Een BMI tussen 18,5 en 24,9 is normaal gewicht. Onder 18,5 is ondergewicht, 25-29,9 is overgewicht en 30+ is obesitas.
▶Is BMI nauwkeurig voor iedereen?
BMI is nuttig als screening maar houdt geen rekening met spiermassa, botdichtheid of lichaamssamenstelling.
▶Is BMI accurate for everyone?
No. BMI doesn't distinguish between muscle and fat mass, so muscular athletes may be classified as overweight despite being healthy. It's also less accurate for elderly people, pregnant women, and growing children. Waist circumference and body fat percentage are often better indicators.
▶What is a healthy BMI range?
The WHO defines 18.5-24.9 as the normal BMI range. However, optimal BMI can vary by ethnicity, age, and individual factors. Some Asian health organizations use lower thresholds (23 for overweight) due to different body composition patterns.
▶Should I rely solely on BMI for health assessment?
No. BMI is a useful screening tool but should be considered alongside other metrics like waist-to-hip ratio, body fat percentage, blood pressure, cholesterol levels, and overall fitness. Consult a healthcare professional for comprehensive health assessment.
