Size Guide

LionFit is built for real bodies — that means giving you real measurements, not just a letter on a label. Use the charts below to find your fit, or check the specific product page for style-specific notes.

How to measure yourself

  • Chest: wrap a tape measure around the fullest part of your chest, under your arms and across your shoulder blades. Keep it snug but not tight.
  • Waist (for joggers/leggings): measure around your natural waistline, roughly level with your belly button.

Measure your actual body, not over existing clothing, for the most accurate result.

Tip: on a phone, swipe left/right on the tables below to see all sizes.

Fit notes by style

  • Fitted / Performance styles (Athletic Gym Shirt, The ORIGIN T-Shirt, Apex Performance Top) — true to size, designed to hug the body. If you're between sizes and prefer a looser feel, size up.
  • Relaxed / Oversized styles (Boxy Oversized T-Shirt, LEGACY Gym T-Shirt, Relaxed Pullover Hoodie, Fluffy Hoodie & Trackpants range) — built with extra room by design for a roomier, layered look. If you prefer a snugger fit, size down.
  • Seamless & Sculpt styles (Sculpt Bra, Sculpt Vest, Sculpt Leggings) — stretch fabric designed to move with you; true to size for most bodies.
