What is the correct procedure for measuring chest, waist, and inseam before ordering scrub sets?

Short answer

To measure for scrub sets, wrap a flexible tape horizontally around the fullest part of the chest under the armpits, the narrowest point of the waist, and from the crotch junction down to one inch below the ankle bone. Keep the tape flat and snug without compressing skin. Size up to the next bracket if your chest or waist falls within a half-inch boundary between standard sizes.

To ensure an accurate fit for scrub sets, measure the chest across the fullest point under the arms, the waist at the narrowest torso line, and the inseam from crotch to ankle bone using a flexible tape.

Medical workwear sizing differs significantly from standard casual retail cuts, requiring functional ease for reaching, bending, and active 12-hour shifts. Taking direct body dimensions prevents restrictive fabric tension across the back while eliminating safety hazards from dragging pant hems.

If you only do one thing: Keep the measuring tape level, flat against the body, and snug without pulling it tight enough to compress soft tissue.

  1. Chest or bust measurement: Stand upright and wrap a flexible vinyl or fabric tape horizontally around the fullest part of the chest, maintaining a level 360-degree line directly beneath the armpits and across the shoulder blades with arms relaxed at your sides.
  2. Natural waist measurement: Locate the narrowest point of the torso, typically 1 to 2 inches above the navel, and wrap the tape snug against the skin or a thin base layer while breathing out normally.
  3. Hip circumference check: Measure around the widest portion of the hips and buttocks, approximately 7 to 9 inches below the natural waistline, ensuring the tape remains parallel to the floor for full seated movement ease.
  4. Inseam length measurement: Stand flat-footed without shoes against a flat wall, measuring the vertical distance along the inner leg from the crotch junction down to 1 inch below the ankle bone or top of the shoe sole.
  5. Size chart matching: Compare your raw circumference and length figures in inches to the garment size matrix, sizing up to the next bracket if your chest or waist falls within a 0.5-inch boundary between standard sizes.
  • Watch out for: Using rigid steel tape measures instead of flexible tailor tapes, which flattens body curves and miscalculates circumference by up to 1.5 inches.
  • Watch out for: Measuring over heavy clothing or bulky sweatshirts, which artificially inflates chest and waist readings by 1 to 2 full sizes.
  • Watch out for: Neglecting shoe outsole height when calculating pant inseams, which causes pant hems to drag under standard 1-inch to 1.5-inch nursing clogs or sneakers.

Record your exact measurements in inches and cross-reference them against the koi size chart before ordering tops, pants, or packaged sets.
