How To Select Your Cover Size

Before choosing a cover, start by considering the notebook inserts you plan to use. Since different brands use similar same size names but often vary in their exact dimensions, please double-check your inserts’ measurements to ensure the correct fit.

Each cover is designed to hold inserts stacked up to one inch in total thickness. If your setup is thicker, or you still aren't sure which size to select after reviewing the below information, we recommend reaching out to us.
