Choosing the right notebook for your leather cover can be as personal as choosing the cover itself. Three names dominate the conversation: Field Notes, Moleskine, and Leuchtturm1917. Each has loyal fans, distinct sizes, and unique paper characteristics. But which one actually fits your Galen Leather cover?
In this comparison, we'll break down the dimensions, paper quality, and practical quirks of each brand. Whether you're a bullet journalist, a daily note-taker, or a fountain pen enthusiast, you'll know exactly which notebook to slide into your favorite leather folio.
Size Matters: Field Notes vs. Moleskine vs. Leuchtturm1917
Field Notes are famously compact at 3.5 x 5.5 inches, perfect for pocket carry. They fit snugly into covers designed for the Field Notes No.33 or No.44 covers, which Galen Leather crafts specifically for these dimensions. If you're always on the go, this size is unbeatable for quick jots and lists.
Moleskine offers several sizes, but the classic Pocket (3.5 x 5.5) and Large (5 x 8.25) are most common. Galen Leather's Moleskine Pocket Cover and Moleskine Large - iPad Mini Cover are tailored to these, so you get a precise fit. The Large size gives more writing space while still being portable.
Leuchtturm1917 comes in A5 (5.8 x 8.3) and A6 (4.1 x 5.8), with the A5 being the go-to for serious journalers. Galen Leather's Leuchtturm1917 A5 Cover and A6 Cover are made to exact specifications, ensuring your notebook stays secure. The A5 is ideal for desk use or a larger bag.
- Field Notes: 3.5 x 5.5 inches (pocket-sized)
- Moleskine: Pocket (3.5 x 5.5) and Large (5 x 8.25)
- Leuchtturm1917: A5 (5.8 x 8.3) and A6 (4.1 x 5.8)
Paper Performance: Fountain Pen Friendly?
If you use a fountain pen, paper quality is non-negotiable. Field Notes uses a 50# paper that's lightweight and dries quickly, but it can show ghosting with wet inks. It's fine for ballpoints and pencils, but fountain pen users may see bleed-through on the next page.
Moleskine's paper is iconic but often criticized for being thin. It handles most pens reasonably well, but with a broad nib or heavy ink flow, you might notice show-through. For everyday writing with a fine or medium nib, it's acceptable, but not ideal for flex nibs.
Leuchtturm1917 uses 80g paper that's a favorite among fountain pen enthusiasts. It resists bleed-through and handles most inks beautifully, especially with finer nibs. If you're using a wet writer like the Leonardo Momento Zero Fountain Pen - Artica ST, this paper will show off the ink's shading without feathering.

- Field Notes: Lightweight, good for dry media, may ghost with wet ink
- Moleskine: Thin but usable with fine nibs, some show-through
- Leuchtturm1917: 80g paper, excellent for fountain pens, minimal bleed
Durability and Cover Compatibility
Field Notes notebooks have a soft cover that's flexible and durable, but they're meant to be carried in a pocket or a dedicated leather cover. Galen Leather's Field Notes covers add a layer of protection while keeping the notebook accessible. The elastic band closure on some covers ensures it stays closed.
Moleskine notebooks feature a hard cover with rounded corners and an elastic band. They're sturdy and classic, but the hard cover can be bulky in a leather slip. Galen Leather's Moleskine covers are designed to accommodate this thickness, so you get a snug fit without stretching the leather.
Leuchtturm1917 also has a hardcover with an elastic band, but it's slightly slimmer than Moleskine's. The A5 size fits perfectly into Galen Leather's Leuchtturm1917 A5 Cover, which is crafted to hold the notebook securely. The cover's leather will mold to the notebook over time, creating a personalized fit.
- Field Notes: Soft cover, flexible, best in a dedicated cover
- Moleskine: Hard cover, classic, slightly bulky
- Leuchtturm1917: Hardcover, slim, precise fit in leather covers
Which Notebook Should You Choose?
Your choice ultimately depends on your writing habits and where you use the notebook. If you're a quick note-taker who needs a pocket companion, Field Notes is the winner. It's compact, affordable, and perfect for on-the-go use, especially with a Galen Leather Field Notes cover.
If you prefer a larger writing area and don't mind a bit of weight, Moleskine Large is a solid choice. It's versatile and widely available, and Galen Leather's Moleskine Large covers add a touch of elegance. Just be mindful of the paper if you're a fountain pen user.
For the best paper quality and a true journaling experience, Leuchtturm1917 A5 is unmatched. It's ideal for bullet journals, long-form writing, and fountain pen enthusiasts. Pair it with a Galen Leather Leuchtturm1917 A5 Cover, and you have a setup that's both functional and beautiful.
