Sizing Formulas

Leather Jacket Sizing

Body Chest + 4" = Jacket Chest

USA standard adds 4 inches of ease to your body chest measurement for leather jackets, allowing natural movement and comfortable layering.

Shearling Jacket Sizing

Body Chest + 6" = Jacket Chest

Shearling jackets require 6 inches of ease due to the thick sheepskin lining, accommodating bulk and layering underneath.

Between Sizes?

Always Size Up

Leather and shearling cannot be stretched. If you're between sizes, order the larger size — leather softens and conforms over time.

How to Measure

Chest Measurement

Wrap the tape around the fullest part of your chest, under your armpits and across your shoulder blades. Keep it parallel to the floor and snug but not tight.

Most important measurement

Waist Measurement

Measure around your natural waistline — the narrowest part of your torso, about 1 inch above your belly button. Stand straight, relax your stomach.

Hip / Seat Measurement

Measure around the fullest part of your hips and seat, usually 7–9 inches below your natural waist. Critical for bomber and longer jacket styles.

Sleeve Length

Start at the center back of your neck, across your shoulder to the shoulder bone, then down the outside of your arm to your wrist with your arm slightly bent.

Fit Tips

Leather breaks in over time: genuine leather softens and conforms to your body after wearing. A slightly snug jacket loosens to a custom fit within 2–4 weeks of regular wear.
Shoulders are non-negotiable: the shoulder seam must sit at the edge of your shoulder bone. Shoulder fit can't be altered — it's the most critical measurement.
Layering under your jacket: if you plan to wear thick sweaters or hoodies underneath, go one size up. Standard sizing assumes a light base layer.
Slim vs regular vs relaxed fit: biker and café racer styles are cut slim — size up for a roomier fit. Bomber jackets are regular fit; shearling coats are relaxed fit.
Measure yourself, not your clothes: never measure a jacket you already own — different brands use different patterns. Always measure your body directly.
