How to Measure

Helly Hansen measuring points — Typical measuring points for Helly Hansen workwear.

Body height: Stand upright against a wall and measure from the top of your head to the floor.

Chest: Measure around the fullest part of your chest, keeping the tape horizontal and under your arms.

Waist (at belly-button height): Measure around your natural waist at navel level, where your body bends side to side.

Waistband: Measure where your trouser waistband normally sits.

Hip: Stand with feet together and measure around the fullest part of your hips and seat.

Inseam: Measure from the crotch straight down the inside of the leg to the floor (or to where you want the hem to end).

Tip: Measure over light clothing. If you are between two sizes, Helly Hansen recommends choosing the larger size for extra comfort and freedom of movement.
