One of the questions I receive most often is:
"What watercolor paper do you use?"
And shortly after that comes another question:
"Why do you use hot-pressed paper instead of cold-pressed paper?"
If you've ever felt confused by the different watercolor paper options available, you're certainly not alone.
When I first started painting, I assumed watercolor paper was simply watercolor paper.
But over time, I discovered that the surface you paint on can completely change the way watercolor behaves.
The paper affects how water moves, how pigments settle, how much detail you can achieve, and even how enjoyable the painting process feels.
Today, I'd like to help you understand the difference between cold-pressed and hot-pressed watercolor paper so you can choose the one that best supports your artistic goals.
Why Watercolor Paper Matters So Much
Many beginners focus on brushes or paints when trying to improve their watercolor results.
But in my experience, watercolor paper often has the biggest impact.
Watercolor is a water-based medium, and the paper is responsible for holding that water, controlling how pigments spread, and giving you enough time to create the effects you want.
Sometimes artists become frustrated with their paintings when the real issue isn't their technique at all. It's simply that they're using a paper surface that isn't suited to the result they're trying to achieve.
That's why understanding paper types can make such a difference.
What about paper weight (GSM)?
Before we talk about hot-pressed and cold-pressed watercolor paper, it helps to understand another term you'll often see when buying paper:
GSM.
GSM stands for grams per square meter, and simply refers to the weight and thickness of the paper.
- Lower GSM papers are thinner and lighter.
- Higher GSM papers are thicker and more resistant to water.
For watercolor artists, this matters because watercolor uses a lot of moisture. Thin paper can buckle, warp, and struggle to handle multiple layers of paint.
As a general guide:
- 190gsm – suitable for sketches, studies, and light watercolor practice
- 300gsm – the most popular choice for watercolor painting
- 640gsm – a very thick professional paper that can handle large amounts of water
Personally, I recommend 300gsm watercolor paper for most beginners. It offers a good balance between performance, durability, and affordability.
The good news is that both cold-pressed and hot-pressed watercolor papers are available in different GSM weights, so you can choose both the surface texture and the thickness that best suits your painting style.
What Is Cold-Pressed Watercolor Paper?
Cold-pressed watercolor paper has a slightly textured surface.
If you gently run your fingers across it, you'll feel small bumps and irregularities.
This texture helps hold water and pigment, which often creates softer, more organic-looking watercolor effects.
Cold-pressed paper is especially popular for:
- Loose watercolor painting
- Landscapes
- Expressive florals
- Atmospheric washes
- Subjects where texture adds character
Many watercolor artists love the beautiful, natural movement that cold-pressed paper creates.
The texture becomes part of the painting itself.
Watercolor settles into the small valleys of the paper, producing effects that can feel spontaneous and full of life.
What Is Hot-Pressed Watercolor Paper?
Hot-pressed watercolor paper has a smooth surface with very little visible texture.
The first time I tried it, I immediately noticed how different it felt.
Pencil lines appeared cleaner.
Brush strokes looked sharper.
Fine details became much easier to control.
Because the surface is smooth, watercolor sits differently on the paper and allows for crisp edges and precise brushwork.
Hot-pressed paper is particularly well suited for:
- Botanical illustration
- Realistic watercolor painting
- Detailed nature studies
- Fine line work
- Scientific illustration
This is one of the main reasons I personally use hot-pressed paper for most of my work.
I enjoy painting detailed flowers, leaves, and nature subjects where precision matters.
The smooth surface allows me to create the fine brushstrokes and crisp edges that would be more difficult to achieve on a textured paper.
See the Difference in Action
If you're a visual learner, I also created a video where I compare cold-pressed and hot-pressed watercolor paper side by side. You'll be able to see how pencil marks, watercolor washes, and fine details behave differently on each surface.
Which Watercolor Paper Is Better?
This is where many artists expect a clear answer.
But honestly, neither paper is better.
They are simply different.
Cold-pressed paper gives you softness and texture.
Hot-pressed paper gives you precision and control.
The best choice depends entirely on what you want your painting to look like.
If you enjoy loose, expressive painting with visible watercolor textures, you may fall in love with cold-pressed paper.
If you enjoy realistic details, botanical subjects, and clean edges, you may prefer hot-pressed paper.
Both can produce beautiful artwork.
The goal is not to choose the "best" paper.
The goal is to choose the paper that supports your artistic vision.
A Simple Exercise to Try
If you're unsure which paper you prefer, I encourage you to experiment.
Paint the same simple subject twice.
Perhaps a leaf, a flower, or a small nature study.
Paint one version on cold-pressed paper and the other on hot-pressed paper.
As you work, pay attention to:
- How the water behaves
- How the colors blend
- How sharp the edges appear
- How much detail you can achieve
You may be surprised by how different the experience feels.
And that understanding will help you make more confident choices in future paintings.

FAQ: Cold-Pressed vs Hot-Pressed Watercolor Paper
What is the difference between cold-pressed and hot-pressed watercolor paper?
Cold-pressed watercolor paper has a textured surface that creates softer, more organic effects. Hot-pressed watercolor paper has a smooth surface that allows for crisp edges and fine detail.
Is hot-pressed watercolor paper better for beginners?
Not necessarily. Beginners can use either paper type. The best choice depends on the style of painting you want to create.
Why do botanical artists use hot-pressed watercolor paper?
Many botanical artists prefer hot-pressed paper because its smooth surface makes it easier to achieve detailed brushwork, clean lines, and realistic textures.
Is cold-pressed watercolor paper better for landscapes?
Cold-pressed paper is often popular for landscapes because the textured surface creates beautiful washes, natural textures, and softer transitions.
Should I try both watercolor paper types?
Yes. One of the best ways to understand watercolor paper is to paint the same subject on both surfaces and compare the results for yourself.
