Formula Used in Sizing Calculator
This tool uses BMI and measurement-based logic to estimate results.
1. Body Mass Index (BMI) Formula
BMI is used to determine body type.
Formula:
BMI=(height/100)2weight
Explanation:
- Weight is in kilograms (kg)
- Height is in meters (converted from cm)
- BMI helps classify body condition
BMI Categories:
| BMI Range | Body Type |
|---|---|
| Below 18.5 | Underweight |
| 18.5 – 24.9 | Normal |
| 25 – 29.9 | Overweight |
| 30+ | Obese |
2. Clothing Size Logic
The calculator estimates size based on chest measurement:
| Chest Size (cm) | Recommended Size |
|---|---|
| < 90 | XS |
| 90 – 95 | S |
| 96 – 103 | M |
| 104 – 111 | L |
| 112+ | XL |
This helps users choose the correct clothing size for tops, shirts, and jackets.
3. Body Shape Formula (Fit Suggestion)
The calculator uses waist, hip, and chest comparison:
- If waist < hip → Pear Shape
- If waist > chest → Apple Shape
- Otherwise → Regular Fit
Logic Explanation:
This method is widely used in fashion design to understand body proportion patterns.
Example Calculation
Let’s understand how the calculator works with a real example:
| Parameter | Value |
|---|---|
| Height | 170 cm |
| Weight | 65 kg |
| Chest | 96 cm |
| Waist | 80 cm |
| Hip | 98 cm |
Step 1: BMI Calculation
BMI=(1.70)265=22.49
➡ Body Type: Normal
Step 2: Size Calculation
- Chest = 96 cm → Size = M
Step 3: Fit Suggestion
- Waist (80) < Hip (98) → Pear Shape Fit
Final Output:
- Body Type: Normal
- Size: M
- Fit: Pear Shape
- Assessment: Based on provided measurements
Sample Sizing Table
| Height (cm) | Weight (kg) | Chest (cm) | Suggested Size | Body Type |
|---|---|---|---|---|
| 160 | 50 | 88 | S | Normal |
| 165 | 60 | 92 | S | Normal |
| 170 | 65 | 96 | M | Normal |
| 175 | 75 | 104 | L | Overweight |
| 180 | 85 | 110 | XL | Overweight |
