Measure a shirt that fits you


Find a shirt that you feel comfortable in, and lay it out on a flat, firm surface. For precision, it is best if you press or iron the garment first. Using a tailor’s measuring tape, take the individual measurements of the shirt as shown on the diagram:

  • Collar
    It is customary to determine the size of a classic tailored shirt by the circumference of the collar. Lay the collar of your shirt out flat, and measure the distance between the center of the button (the point where it is attached to the shirt), and the middle of the buttonhole.
     
  • Chest
    Make sure the shirt is fully buttoned, and measure the distance in the widest spot just under the sleeves. Multiply this distance by two to get a circumference.
     
  • Waist
    With the shirt still buttoned and lying flat, measure the distance between the side seams, at the narrowest point of the body. Multiply this distance by two to get a circumference.
     
  • Hips
    With the shirt still buttoned and lying flat, measure the distance between the side seams, at the point where the seams meet the hemline. Multiply this distance by two to get a circumference.
     
  • Sleeve length
    Lay the sleeve out flat, and measure the distance between the uppermost point of the sleeve to the edge of the cuff. Make sure the sleeve does not twist while you measure.

Make a note of all the measurements, and look for the closest matching size in the table. If your measurements are between two sizes, it is usually a good idea to go one size up.

Take your body measurements


If you would like to determine the required size using your body measurements, it is a good idea to ask somebody to take the measurements while you stand still. With a tailor’s measuring tape, take the individual measurements as described

Collar
It is customary to determine the size of a classic tailored shirt by the circumference of the collar. When taking the measurement, mimic the shape of a shirt’s collar with the measuring tape, gripping both ends of the tape in front of your neck. Typically, you should be able to fit one finger between you neck and the tape for a well-fitted collar measurement.

  • Chest
    Take a measurement around the widest part of your chest, while inhaling lightly. Add 7cm / 2.5in to the measurement for freedom of movement.
     
  • Waist
    Take a measurement around the narrowest point in your waistline, while breathing normally. Add 7cm / 2.5in to the measurement for freedom of movement.
     
  • Hips
    Take a measurement around your hips, at the widest point of your pelvis. Add 7cm / 2.5in to the measurement for freedom of movement.
     
  • Sleeve length
    With your arm extended downwards, take a straight-line measurement from the point where your shoulder meets your collarbone to the point below your wrist where you would like your cuff to sit add 2.5cm / 1in to the measurement for freedom of movement.

Make a note of all the measurements, and look for the closest matching size in the table. If your measurements are between two sizes, it is usually a good idea to go one size up.
