Measuring tips
- Position yourself barefoot and upright against a wall, ensuring your heels, back, shoulders, and head are touching it. Keep your gaze forward and chin slightly down.
- Gently set a book on top of your head, then align it gently against the wall to ensure it's level with the ground.
- Take the measurement from the base of the book straight down to the floor to determine your height.
Measuring tips
- Dress in cycling bibs, tights, or snug-fitting underwear and stand without shoes, your back against a wall.
- Place a book between your legs, mimicking the position of a bike saddle, and snugly raise it up to your crotch.
- Measure the distance from the top of the book straight down to the floor to find your inner leg length.
