- 1 · Ultra Slim — folio and bookcover designs for a single notebook or bound book, occasionally a second very slim companion.
- 2 · Slim Everyday — ideal for 2–3 inserts and a simple, graceful daily carry.
- 3 · Standard Stuffable — designs with strap closures, happiest with 3–4 average inserts and a little room for dashboards.
- 4 · High Capacity — Traveler’s Notebooks with elastic closures that love layered, “chunky” journaling setups.
- 5 · Maximalist — trifolds and leather wrap styles for generous, overflowing notebooks and keepsakes.
Strap-closure designs are most content with three to four average inserts and a dashboard or two that do not exceed 1.25 inches or 2.7cm. The strap keeps everything neat and secure, but it does not stretch like elastic, so a moderate, tidy setup is ideal.
