the notches arent number or are standard, theyre about 0. APPEARANCE : the product gives a clean, sleek look to my closet and even somewhat of a high end closet vibe. I am a XXL but I thought I needed to order up. I suffer from a bunion, a bunionette and arthritis in my left foot due to a broken toe 20 years ago. I waited a while before posting a review so that I could use this extensively first. My husband likes to wear earbuds at work and these ones stay in his ears all day without popping out. We had to travel 300 miles. The shelf is sturdy. But not this bad boy. used the elastic band for fitted sheets, very weak hold, the old band was stronger than this one.
