A binder spacer for use with a looseleaf notebook. The binder spacer is removably attached to one of the covers of a notebook by a clip. Spacing members depending generally perpendicularly from the clip keep the covers in a substantially parallel orientation. The spacing members are sized to match the space between the covers which necessarily approximate the width of the notebook's spine. Because looseleaf notebooks come in different sizes, the binder spacer comes in different sizes to accommodate for the varying notebook sizes.
