When it comes to watercolor, your paper is more than a surface—it's the foundation of your painting. That's because watercolor relies on the interaction between paint and paper. How pigments settle, spread, and dry depends on the paper's texture, absorbency, and weight. It's the paper that gives watercolor paintings their signature softness and fluidity.
But when you're just starting out, the choices can be overwhelming. How do you choose between textures, weights, and finishes—and why does it matter?
This guide breaks down the differences between hot press, cold press, and rough press watercolor papers to explain how texture, absorbency, and weight affect your painting. Understanding these basics will help you pick the perfect paper to bring your watercolor work to life.
Watercolor paper isn't just regular paper—it's specially made to handle the demands of wet media. Unlike standard drawing or printer paper, it's built to absorb water without buckling, tearing, or dulling your colors.
Most watercolor papers are made from either 100% cotton, wood pulp, or a blend of both. Cotton paper is considered the highest quality because it's durable, absorbent, and gives you more time to work with your paint. Pulp-based papers are more affordable and still perform well, especially for beginners or practice pieces.
But material is only part of the story. The way the paper is made—handmade vs. machine-made—and the surface finish (hot press, cold press, or rough) also have a big impact on how your paint behaves.

Hot press paper is pressed between heated rollers, giving it a smooth, almost slick surface. There's little to no texture, which makes it perfect for detail work, crisp lines, and mixed media like ink or graphite. Paint tends to sit on top a bit longer, giving you more time to blend—but it also means colors can feel less vibrant if you're not careful.
Hot press paper is used for:
Botanical illustrations and detailed work
Architectural drawings and technical art
Mixed media combining watercolor with ink or graphite
Smooth, even washes without texture interference
Because the paint sits on the surface longer, you can lift colors easily for corrections, making it surprisingly forgiving despite its reputation as a "challenging" paper.
Cold press paper is the most versatile and the most popular type for a reason. It's made by pressing sheets through cold felt-covered rollers, creating a soft, pebbly texture. This "tooth" grips the paint and creates natural granulation and soft edges. It's great for beginners and pros alike—easy to work with, forgiving, and suitable for most watercolor techniques.
Cold press paper works beautifully for:
Landscapes and nature scenes
General watercolor painting and practice
Learning new techniques and building skills
Plein air painting where versatility matters
The balanced absorption rate gives you enough time to work with wet paint without it sitting too long on the surface. Most artists consider cold press their go-to paper for everyday painting.
Rough paper is exactly what it sounds like—more texture, more tooth, more drama. The pronounced surface grabs pigment in unexpected ways, making it ideal for expressive washes and atmospheric effects. It's not as easy to control, so it's better suited for looser styles or artists who like to let the paint do its thing.
Rough paper shines for:
Expressive, loose painting styles
Atmospheric effects like stormy skies and fog
Seascapes and dramatic landscapes
Large-scale paintings where texture adds impact
The fast absorption means you need to work quickly, but the payoff is dramatic granulation effects and rich, textured appearances that you can't achieve on smoother surfaces.
Understanding how watercolor paper is made helps explain why some papers perform better than others. The manufacturing process affects fiber strength, texture, absorbency, and overall quality.
Handmade paper represents the highest quality. It's crafted using a wooden frame (mold) and deckle, resulting in strong fibers and natural "deckled" edges on all sides. The random fiber orientation creates superior strength and paint handling.
Moldmade paper is made on a rotating wire mesh cylinder. These papers have two natural deckle edges and strong fiber interlacing, providing excellent quality suitable for most professional use while being more affordable than handmade options.
Machine-made paper is produced rapidly on machines. These papers are less durable because fibers are aligned mostly in one direction. They're best suited for practice or student-grade work.
Texture—also called the paper's "tooth"—is key to how your pigments settle. Hot press paper's smoothness means paint sits on the surface longer, allowing more control but less natural texture. Cold press paper's bumps cause pigment to pool in tiny valleys, creating natural granulation and subtle texture in washes. Rough press amplifies this effect with even bolder texture, perfect for expressive, atmospheric work.
Cold press paper absorbs paint faster than hot press, meaning you have less time to move pigment before it sets. This can be great for layering but requires quicker brushwork. Hot press paper's slower absorption allows more blending time and sharper edges. Rough press paper absorbs paint quickly due to its texture, making drying time fast and granulation pronounced.
Watercolor paper weight affects durability and warp resistance. GSM (grams per square meter) is the most reliable measurement, with 300 gsm (140 lb) being the industry standard. Lighter papers (around 190 gsm) tend to buckle easily when wet, while very thick papers (350+ gsm) absorb faster and may not need stretching before use.
Cotton fibers are strong, flexible, naturally white, and acid-free, making them ideal for archival watercolor paper. Wood pulp papers are cheaper but tend to yellow, become brittle, and degrade faster. Most professional watercolor papers are 100% cotton, offering superior durability and paint handling that makes them worth the extra cost.
Which paper is best for beginners? Cold press is the easiest to work with—it's forgiving, versatile, and well suited for learning.
Why is lifting paint easier on hot press paper? Because the surface is smooth and less absorbent, pigment sits on top longer, allowing easier correction.
Is rough press suitable for wet-on-wet techniques? Yes, it’s great for creating bold, textured granulation effects during wet-on-wet painting.
Which paper scans or reproduces best? Hot press is the best choice due to its smooth, even surface that captures detail clearly.
Here's how to make the best choice for your needs:
Start small: Experiment with sample sheets of hot, cold, and rough press papers to see which surface suits your style
Invest in quality: Always aim for 100% cotton and acid-free papers for professional results
Consider weight: 300 gsm is ideal for most work to prevent warping without stretching
Mix and match: Don't be afraid to use different papers within a single project to maximize texture and detail
The right paper can transform your watercolor experience. Take time to understand these differences, experiment with different surfaces, and find what works best for your artistic vision.
