I’ve filled more watercolor sketchbooks than I can count at this point, and I’ve learned the hard way that not all sketchbooks are created equal.
A great watercolor sketchbook can make the painting process feel smooth and enjoyable, while a bad one will have you fighting with the paper instead of focusing on the art. Whether I’m out in the field or working at home, the right sketchbook changes everything.
When I’m picking a watercolor sketchbook, I’m looking for a mix of portability, durability, paper quality, and how it feels when I paint. It’s not just about weight or price.
It’s about how the sketchbook supports my process, from wet-on-wet washes to ink and wash combinations. I also think about how the book encourages me to paint more. Some sketchbooks make me want to open them up and paint every day. Others just sit on the shelf.
Key Points
- Paper matters most. If it can’t take a decent wash without buckling or pilling, I’m out. Look for 100% cotton if possible.
- Binding affects how I paint. I prefer sketchbooks that lay flat or let me use a full spread. Spiral-bound is great for outdoor work.
- Not all pages are equal. Some sketchbooks only have watercolor paper on one side, which limits how much I can use them.
What I Look for First in a Watercolor Sketchbook
I start with the paper. Always. Before anything else, I want to know how it behaves with actual watercolor paint. It’s easy to fall for a beautiful cover or a trendy brand, but if the paper doesn’t hold up, the sketchbook becomes just a nice object to look at.
Paper Quality
For me, the best watercolor paper has a bit of tooth, enough thickness to handle layered washes, and minimal warping. I usually go for 300gsm (140lb) paper, and ideally 100% cotton. This kind of paper allows me to work in multiple layers without worrying that the surface will start to fall apart. I do sometimes use sketchbooks with cellulose paper if I’m just doing light washes or planning compositions, but they’re more limited.
Some sketchbooks use internally sized paper, meaning the sizing is part of the pulp itself. Others are surface-sized, which can sometimes feel a little more slick. I usually prefer internally sized paper, but I always test with a wash and a bit of scrubbing to see how it holds up.
If you're still figuring out your preferences, I’ve put together a helpful overview of types of watercolor paper that breaks down the differences between hot press, cold press, and rough surfaces.
Paper Color and Texture
I’ve used some sketchbooks where the paper has a yellow tint, or is so smooth that watercolor beads up awkwardly. I prefer a slightly warm white or neutral white—something that makes the colors pop but still looks natural. Texture-wise, I want just enough tooth to allow dry brush techniques and granulation to show up, without it feeling like I’m dragging my brush through sand.
Binding, Size, and Format
The sketchbook’s format influences how and where I use it. When I’m traveling or sketching outdoors, I like a compact spiral-bound option that lays flat and lets me flip pages easily. But in the studio, a hardbound book with stitched pages feels better. The binding also affects how I scan or photograph artwork later on.
Size and Orientation
My go-to size is somewhere around 5×8 inches for travel and 8×10 or 9×12 inches when I want more room. Larger sketchbooks give me space to play with composition and layering, but they’re not as convenient for field work. If I’m going on a hike or painting on location, I usually stick to A5 size.
Orientation plays a bigger role than I expected when I first started. Landscape orientation is ideal for wide views like mountains, coastlines, or street scenes. Portrait orientation works well for vertical compositions like trees or buildings. I’ve also used square sketchbooks, which force me to think more carefully about layout.

Binding Type
Spiral bindings are practical. They lay flat and let pages dry without smudging the one next to it. They’re easier to manage when I’m out sketching and don’t have a table or flat surface to work on. But spiral bindings can snag or get bent in bags, so I’m careful with how I pack them.
Stitched or case-bound books feel more solid and look nicer on a shelf. I reach for them when I want to build a cohesive body of work. Some hardcover options, like my favorite hot press watercolor sketchbook, even open perfectly flat across the spread. That’s ideal for panoramic scenes or when I want to scan a spread without distortion.
How the Pages Handle Water
The biggest test for any sketchbook is how the pages react when I put down water-heavy washes. Do they buckle? Do they tear when I lift pigment? Can I do a wet-on-wet technique without stress? That’s where a good book sets itself apart.
When the paper handles water well, I can be more experimental. I can tilt the book to let the paint flow, or go back in with a wet brush to lift pigment without damaging the paper. I’ve used some sketchbooks where the sizing completely breaks down after one or two layers, making the whole page feel gummy. Others allow me to layer colors, lift highlights, and glaze over areas without any problem.
I also pay attention to how the paper takes ink and wash. I love combining pen lines with watercolor, so I want a surface that doesn’t feather or bleed when I draw with fountain pens or fineliners. And when I’m doing color studies, I often refer to my color mixing chart to test blends and layering on the page.
Durability and Everyday Use
I’m not gentle with my sketchbooks. I throw them in bags, paint in damp weather, and flip pages while my hands are covered in paint. The cover, the spine, the paper edges—all of that needs to handle wear and tear.
Cover Strength and Page Count
I lean toward hardcover or at least a firm softcover. Flimsy covers get bent too easily. A hardcover helps me paint when I don’t have a table, especially if I’m sketching on my lap. I also think about how much the sketchbook invites me to keep going. If a book has too many pages and I know I won’t finish it, I’ll hesitate to start.
Page count matters too. I don’t want a 200-page book if I can’t actually paint on both sides. Some sketchbooks only size one side of the paper, which means I lose half the book. That’s why I always check if the paper is sized front and back, especially for sketch pads made for watercolor.
Sketchbooks I’ve Actually Enjoyed Using
I’ve tested a lot of them. Here are a few I’ve returned to multiple times:
- Hahnemühle Watercolor Book – Reliable 200gsm paper, travel-friendly, and the texture is just right. It’s cellulose, but still handles light washes well.
- Etchr Lab Sketchbook – Cotton paper, beautifully bound, and opens flat. A bit pricier but worth it when I want something special.
- Handbook Watercolor Journal – Affordable and solid for ink and light washes. Not ideal for heavy layering, but great for sketching on the go.
These days, I also test the paper with my full watercolor setup, including brushes I recommend for beginners and my go-to masking tape. If a sketchbook can’t work with my normal setup, it’s not worth using. You can see a full breakdown of materials and how they interact with the paper in my watercolor section here.
Other Considerations
There are a few other things that might not be deal-breakers but are still worth thinking about.
- Storage: If I’m filling lots of books, I need to store them efficiently. I go into that here: watercolor storage. Some of my older books are stacked vertically, while others are laid flat to prevent warping.
- Flattening: Sometimes you’ll want to flatten a finished painting, especially if it warped a bit during the process. Certain bindings make this easier.
- Materials: I like experimenting with water-soluble wax pastels and watercolor pastels in my sketchbooks too, so I want paper that can handle a bit more than just paint.
- Color Practice: Lately, I’ve been doing more exercises like making skin tones or neutral grays directly in my sketchbook. I use dedicated spreads just for that.
