Clothing Size Measurement Guide: How to Measure Bust, Waist & Hips

Updated: May 27, 2026

Tools You Need

  • Soft flexible tape measure (sewing/dressmaker’s tape)
  • Mirror or a helper (for back measurements)
  • Underwear only — never measure over clothing

How to Measure: Women’s

Bust

  1. Stand straight, arms relaxed at sides
  2. Wrap tape around the fullest part of your bust, parallel to the floor
  3. Do not pull tight — tape should be snug but not compressing
  4. Round to the nearest 0.5” (0.5 cm)

Common error: Measuring over a heavily padded bra inflates the bust measurement. Measure in a thin bralette or unlined bra.

Waist

  1. Find the natural waist — the narrowest part of your torso (above the hip bones, roughly 1–2 inches above the belly button)
  2. Exhale naturally, do not suck in
  3. Wrap tape snugly around the natural waist

Common error: Measuring where you wear your jeans (low waist) rather than the natural waist. Low waist = hips, not waist.

Hips

  1. Stand with feet together
  2. Measure around the fullest part of hips and buttocks — usually 7–9 inches below the natural waist
  3. Keep tape parallel to the floor

Common error: Measuring too high (at the hip bones) instead of the fullest part 8 inches below the waist.


How to Measure: Men’s

Chest

  1. Wrap tape around the fullest part of the chest, usually just below the armpits
  2. Keep tape parallel to the floor
  3. Arms relaxed at sides

Waist

  1. Measure around the natural waist for shirt/suit sizing
  2. For trouser sizing: measure where you actually wear your trousers (usually lower, at the hip bone level)

Note: Shirt waist = natural waist. Trouser waist = lower — check which is being referenced on the size label. For dress shirt collar sizing and trouser inseam details, see the Men’s Clothing Size Guide.

Inseam (trousers)

  1. Stand barefoot
  2. Measure from the crotch seam to the floor, or to your preferred trouser break
  3. Standard breaks: no break (contemporary), slight break (classic), full break (traditional)

How to Measure: Kids

Use height as the primary measurement — it’s more consistent than age or weight across brands.

MeasurementTechnique
HeightStand barefoot against a wall. Mark top of head. Measure from floor to mark.
ChestAround fullest part of chest, just below armpits.
WaistAround natural waist, relaxed (not sucked in).
InseamCrotch to floor, barefoot.

For kids, always cross-check with the specific garment’s size chart — children’s sizing varies more by brand than adult sizing. See Why Clothing Sizes Vary by Brand for how brand-level variation affects all sizes.

When Your Measurements Fall Between Sizes

Size up: If any measurement falls in the next size up, take the larger size. Clothing can be altered (taken in) — the opposite direction (letting out) requires seam allowance.

Fit priority by garment type:

  • Tops and jackets: Bust/chest is primary. Shoulders must fit — can’t be altered easily.
  • Trousers and skirts: Waist or hips (whichever is larger) is primary. Waist can be taken in; hip cannot be let out easily.
  • Dresses: Largest of bust/waist/hips is primary. Buy for widest part, alter elsewhere.
