📏 SHOULDER MEASUREMENT GUIDE

How to Measure Shoulder Width:
For Perfect Jacket Fit

Master the professional technique for measuring shoulder width. Essential for custom suits, jackets, and shirts that fit perfectly across the shoulders.

What is Shoulder Width?

Shoulder width (also called shoulder breadth) is the distance measured straight across your back from the outer edge of one shoulder to the outer edge of the other shoulder. This measurement determines where jacket and shirt shoulder seams sit on your body.

Proper shoulder fit is the most important aspect of jacket fit - it's nearly impossible to alter significantly after construction. Unlike sleeves or waist, shoulders must be right from the start.

Why Shoulder Measurement Matters

  • Impossible to alter - Shoulder construction is permanent in most jackets
  • Affects silhouette - Wrong shoulders make the entire jacket look ill-fitting
  • Impacts comfort - Too narrow restricts movement, too wide looks sloppy
  • Defines your look - Proper shoulders create a professional, tailored appearance

How to Measure Shoulder Width: Step-by-Step

What You'll Need:

  • Flexible fabric measuring tape
  • A helper (strongly recommended - very difficult to do alone)
  • Form-fitting shirt (optional, helps locate shoulder points)
1

Stand Naturally

Stand up straight with your shoulders relaxed in their natural position. Don't pull your shoulders back or push them forward. Arms should hang naturally at your sides. Remove bulky clothing - measure over a thin shirt or bare skin.

2

Locate Shoulder Points

The shoulder point is where your shoulder bone ends and your arm begins. To find it:

  • • Feel along the top of your shoulder bone (acromion)
  • • Find where it ends at the edge of your shoulder
  • • This is where suit jacket shoulder seams should sit
  • • Look at a well-fitting jacket for reference if needed
3

Measure Across Back

Have your helper measure straight across your back from one shoulder point to the other:

  • • Keep the measuring tape parallel to the floor
  • • Tape should lay flat across your back (not droop)
  • • Don't pull tape tight - it should rest gently on your back
  • • Record measurement in inches or centimeters

Pro tip: Measure 2-3 times to ensure consistency. The measurement should be the same within 1/4 inch each time.

Common Mistakes

Measuring over thick clothing

Bulky sweaters or jackets add extra width. Measure over thin shirt or bare skin.

Pulling shoulders back unnaturally

Stand naturally. Forced posture gives inaccurate measurements.

Measuring from front

Always measure across the back for accurate shoulder width. Front measurements are unreliable.
