A Guide to Choosing the Right Watercolour Paper

When it comes to watercolour painting, the paper you choose can significantly impact your final artwork. While the paint, brushes, and techniques are crucial, the paper serves as the foundation, influencing the texture, colour vibrancy, and overall quality of your work. In this blog, we'll explore the key factors to consider when selecting watercolour paper, including absorbency, colour, stability, and grain, along with a few additional factors.

Stability refers to how well the paper maintains its shape and integrity when wet. High-quality watercolour papers are designed to handle large amounts of water without warping, buckling, or tearing.

Sizing is a treatment applied to watercolour paper to control its absorbency. External sizing is applied to the surface of the paper, while internal sizing is mixed into the paper pulp. Properly sized paper prevents the paint from soaking in too quickly, allowing for better control and more vibrant colours.

Absorbency is one of the most important aspects of watercolour paper. It refers to how well the paper soaks up water and pigment. Papers with high absorbency allow for smooth washes and subtle gradients, making them ideal for techniques like wet-on-wet painting. However, overly absorbent paper can cause colours to appear dull. On the other hand, less absorbent papers keep pigments on the surface longer, which can result in more vibrant colours but may also lead to less control over blending. Finding a balance that suits your painting style is key. 

The colour of the paper can affect the overall tone and mood of your artwork. Most watercolour papers come in white or off-white shades. Bright white papers tend to make colours pop and appear more vibrant, whereas off-white or cream-coloured papers can give a warmer, more subdued effect. Consider the atmosphere you want to create in your paintings when choosing the paper colour.

The grain, or texture, of watercolour paper can vary from smooth (hot-pressed) to rough. Smooth, or hot-pressed paper, is ideal for detailed work and fine lines. Cold-pressed paper has a moderate texture and is the most versatile, suitable for a wide range of techniques and styles.

Rough paper has a pronounced texture that can add a dynamic, expressive quality to your paintings. Your choice of grain should align with your preferred painting techniques and the desired texture in your final piece.

Watercolour paper is typically made from cotton, wood pulp, or a blend of both. 100% cotton papers are generally the highest quality, offering superior durability and absorbency.

Papers with wood pulp are more affordable but may not perform as well under heavy washes.

Watercolour paper comes in various formats, including sheets, blocks, pads, and rolls. Sheets are versatile but require stretching to prevent warping. Blocks are pre-stretched and glued on all sides, offering convenience and stability.

Pads are portable and great for studies or practice. Rolls provide large, continuous sheets for bigger projects.

Not all watercolour papers are created equal. Established brands like Arches, Saunders Waterford, and Fabriano are known for their high-quality papers. Investing in reputable brands can make a noticeable difference in your painting experience and results.

Choosing the right watercolour paper involves understanding how different characteristics affect your painting process and outcomes. Absorbency, colour, stability, and grain are crucial factors, but do not forget to consider the composition, sizing, format, and brand quality. By carefully selecting your watercolour paper, you can enhance your artwork and fully enjoy the expressive potential of this beautiful medium.
