If you already have inserts:
Measure them carefully and find the size that is their closest match on the chart above. If you are between two notebook sizes, always choose the larger one. Next, stack up the number of inserts you’d like to carry and measure how thick they are together. This tells you how thick your spine will be when your notebook wraps around the inserts. Compare this to the width of the notebook you’re considering.
For example, if you are using inserts that are 4.5” x 8.25”, and your stack of inserts is 1” high, you’d know you’d need the Narrow size. But if your stack is larger than 1”, you’d want to go up to the Wide.
