BMI Category Weight Table (for your height)

This table shows weight ranges for standard BMI categories based on your height. Use it to plan healthy targets.

BMI Category BMI Range (kg/m²) Weight Range (kg) Weight Range (lb)
Enter height and click Calculate to generate the table.

Examples & Guide

Example 1

Height = 175 cm (1.75 m), Desired BMI = 22 → Weight = 22 × 1.75² = 67.38 kg (~148.6 lb).

Example 2

Height = 160 cm (1.60 m), Desired BMI = 18.5 → Weight = 18.5 × 1.6² = 47.36 kg (~104.4 lb).

Quick formula

Weight (kg) = Desired BMI × (Height in meters)². Convert kg → lb: 1 kg ≈ 2.20462 lb.

Why this tool matters

A reverse BMI calculator helps set target weight goals based on BMI ranges recommended for health. It makes goal-setting clear and quantifiable.

Use cases (workplace & industry)

Applicable beyond personal fitness — employers and safety officers in construction, carpentry, CAD workstations and piping teams can use it for ergonomic planning, health screenings, and job-fit assessments.

Short Guide: Setting a Realistic Target Weight

  1. Choose a desired BMI in the healthy range (18.5–24.9) for most adults.
  2. Enter your height and click Calculate Target Weight.
  3. Review the BMI category table to understand weight ranges for your height.
  4. Consult a healthcare professional before starting major weight changes — BMI is a screening tool, not a full health assessment.

Frequently Asked Questions

What is a reverse BMI calculator?
A reverse bmi calculator takes a desired Body Mass Index (BMI) and a person’s height to compute the target weight required to reach that BMI.
Is BMI an accurate measure of health?
BMI is a quick screening tool; it does not measure body fat directly. Use it as a general guide and combine with other measures — body composition, waist circumference, and professional advice.
Can I use this calculation for children?
No. Pediatric BMI uses age- and sex-specific percentiles; this simple reverse BMI calculator is intended for adults only.
How accurate is the output?
The calculator applies the mathematical formula exactly. For health decisions, consult a doctor or dietitian.
