How to Measure Your Chest to Choose the Correct Shirt Size

  1. Use a measuring tape: Select a soft, flexible tape measure for accurate readings.
  2. Remove thick clothing: For best accuracy, wear a light T-shirt or no top at all.
  3. Measure around your chest: Place the tape around the fullest part of your chest, just under your arms and across your shoulder blades. Ensure the tape is level and comfortably snug — not too tight.
  4. Record the measurement in centimetres: Stand naturally, breathe normally, and note the measurement.
  5. Refer to the size guide: Match your measurement to the correct UK shirt size. For instance, 100–101 cm = L (Large).
