Fit & Style Advice

Your measurements suggest a modern fit. For personal comfort, always try on suits before purchasing.

Finding the right suit jacket can be challenging. Ill-fitting jackets can ruin your look, while perfectly tailored ones enhance your style and confidence. The Suit Jacket Size Calculator is a simple, effective tool designed to help you determine your ideal suit jacket size, fit, and proportions based on your body measurements.

This calculator takes into account gender, height, weight, chest and waist measurements, and your preferred fit to provide personalized recommendations for a stylish, comfortable suit.


How to Use the Suit Jacket Size Calculator

Using the Suit Jacket Size Calculator is straightforward. Follow these step-by-step instructions:

Step 1: Select Your Gender

Choose between Male or Female. This ensures that the sizing recommendation matches standard European sizing charts for your gender.

Step 2: Enter Your Height

Input your height in centimeters. The calculator will use this to recommend an appropriate jacket length (short, regular, or long).

Step 3: Enter Your Weight

Provide your weight in kilograms. This helps refine the fit suggestion to ensure the jacket is neither too tight nor too loose.

Step 4: Input Your Chest Circumference

Measure around the fullest part of your chest and enter it in centimeters. This measurement forms the basis of the jacket size calculation.

Step 5: Input Your Waist Circumference

Measure your waist at the narrowest point and enter it. This ensures the jacket waist fits comfortably.

Step 6: Choose Your Preferred Fit

Select Regular, Slim, or Loose based on your style preference. The calculator adjusts the recommended size accordingly.

Step 7: Click Calculate

Hit the Calculate button. The tool will display a progress bar while processing your measurements, then show your personalized results.

Practical Example

Let’s say you are a male with the following measurements:

  • Height: 175 cm
  • Weight: 72 kg
  • Chest: 100 cm
  • Waist: 85 cm
  • Preferred Fit: Slim

After entering these values:
