Size Guide

Steps to Predict Chest Size from T-Shirt Dimensions:

  1. Measure the T-Shirt's Chest Width.
  2. Double the Chest Width.
  3. Compare with Body Measurements.

Example:

  • T-Shirt Chest Width: 20 inches.
  • T-Shirt Chest Circumference: 20 inches x 2 = 40 inches.
  • Body Chest Measurement: If your chest measures around 38-39 inches, a T-shirt with a 40-inch chest circumference should fit comfortably.
