    • Step 3: Measure the headroom – The headroom is the space above the garage door opening to the ceiling. Measure from the top of the opening to the ceiling.
    • Step 4: Measure the backroom – The backroom is the distance from the garage door opening to the back of the garage. Measure from the opening to the back wall of the garage.
