Rough paper is watercolor paper with the heaviest texture, left to dry with minimal pressing. Learn how it creates dramatic granulation, its history, and why landscape painters prefer it.
Paint a wash on rough paper and the pigment does not spread evenly. It catches on the raised peaks of the surface and skips the deep valleys. The result is a broken, mottled, irregular wash that looks like it painted itself. This is the point. Rough paper does the textural work for you. A single sweep of a loaded brush across rough paper produces the kind of granulation that would require multiple layers and careful technique on a smoother surface. For landscape painters who want to suggest the texture of rocks, the surface of water, or the roughness of bark without painting every detail, rough paper is the tool.
Rough paper is watercolor paper that has been left to dry with minimal pressing during manufacturing, producing the heaviest and most pronounced surface texture of the three standard watercolor paper types. The surface has deep, irregular peaks and valleys that cause pigment to settle unevenly, creating dramatic granulation and broken edges. Rough paper is one of three standard watercolor paper textures, alongside hot pressed (smooth) and cold pressed (lightly textured). It is the least commonly used of the three but the most distinctive in its effects.
This entry covers how rough paper is made, its history, which artists and subjects benefit from it, and how to use it effectively.
The texture of watercolor paper is determined by how it is pressed after the pulp is formed into a sheet. Hot pressed paper passes through heated metal rollers that compress the fibers flat. Cold pressed paper passes through cold felt-covered rollers that leave a moderate texture. Rough paper goes through minimal pressing. The sheet is formed on a mold or wire screen and then dried with little or no calendering, which means the natural texture of the pulp and the impression of the mold remain on the surface.
For handmade rough paper, the sheet is formed on a mesh mold, drained, and dried without pressing. The mesh leaves a visible pattern, and the fibers settle into the irregular surface of the mold. For cylinder mold-made rough paper, the sheet is formed on a rotating cylinder covered with wire mesh, pressed lightly to remove excess water, and dried with minimal calendering. The result is a surface with heavy, irregular peaks and valleys that are deeper and more pronounced than cold pressed paper.
The texture of rough paper varies between manufacturers. Arches rough has a bold, almost mountainous surface with deep valleys. Fabriano Artistico rough is slightly less extreme. Saunders Waterford rough has a more even, regular texture. The Russell Collection guide describes rough paper as having "heavy, irregular peaks and valleys across the sheet" that cause paint to catch on raised peaks and skip the valleys, creating broken edges without any extra technique.
Rough paper changes how watercolor behaves in ways that are immediately visible. When you lay a wash on rough paper, the brush touches only the peaks of the surface. The pigment deposits on the high points while the valleys remain lighter or unpainted. This creates a broken, granulated effect that looks natural and atmospheric. The effect is amplified with granulating pigments like ultramarine, burnt sienna, and cerulean blue, which naturally separate into particles of different sizes. On rough paper, these pigments produce dramatic textural variation.
The deep texture also affects drying time. Rough paper absorbs paint quickly because the valleys act as reservoirs for water. This means washes set faster than on hot pressed paper, giving you less time to blend but producing more textural interest. The Blick Art Materials guide notes that rough paper absorbs paint quickly due to its texture, making drying time fast and granulation pronounced.
Dry brushing on rough paper is particularly effective. A brush loaded with thick paint and dragged across the surface catches only the peaks, leaving the valleys unpainted. This creates a broken, textured stroke that is ideal for suggesting the roughness of tree bark, stone, or weathered surfaces. On smoother paper, the same technique produces a less dramatic effect because there are no deep valleys to skip.
Rough paper predates the industrial distinction between hot pressed, cold pressed, and rough surfaces. Before the 19th century, all handmade paper had some degree of texture because it was formed on mesh molds and dried without mechanical pressing. The earliest watercolor papers, made from cotton and linen rags at mills like Whatman in England, were naturally textured. When hot pressing was developed to produce smooth paper for printing and illustration, the original, less-pressed surface became known as "rough" to distinguish it from the new smooth and moderately pressed surfaces.
The English watercolor school of the late 18th and early 19th centuries embraced rough paper for landscape painting. J.M.W. Turner (1775-1851) used rough paper for many of his later watercolors, where the texture of the surface contributes to the atmospheric, almost abstract quality of the work. His Storm at Sea (c. 1840-1845) and the Swiss watercolor studies of the 1840s show how rough paper can suggest the chaos of water and weather without detailed rendering. John Sell Cotman (1782-1842) also used rough paper, though his Greta series watercolors show a more controlled use of the surface texture.
In the 19th century, as paper manufacturing industrialized, the three surface types were standardized. Mills like Arches, Fabriano, and Whatman produced rough paper as a distinct product alongside their hot pressed and cold pressed lines. The cylinder mold machine, which replicated the texture of handmade paper, allowed for consistent production of rough surfaces at scale.
Turner is the artist most associated with rough paper in the English watercolor tradition. His later watercolors, particularly the Swiss and Venetian studies of the 1830s and 1840s, exploit the texture of rough paper to create atmospheric effects that would be impossible on a smoother surface. The granulation of washes on rough paper suggests mist, cloud, and the movement of water with a looseness that approaches abstraction. Many of these works are in the Turner Bequest at the Tate, viewable at Tate's Turner collection.
Homer used rough paper for his watercolors of the Maine coast, the Caribbean, and the Adirondacks. The texture of the surface contributes to the sense of wind, spray, and natural roughness in his landscapes. Northeaster (1895, watercolor on rough paper) and the Bahamas watercolors of the 1880s show how rough paper can suggest the energy of moving water and the texture of rocks without laboring every detail. Homer's watercolors are in the collection of the Metropolitan Museum of Art and the National Gallery of Art.
Sargent used both cold pressed and rough paper for his watercolors, choosing the surface based on the subject. His Alpine watercolors and Venetian scenes often use rough paper, where the texture enhances the sense of mountainous terrain and crumbling architecture. The Brooklyn Museum and the Museum of Fine Arts, Boston, hold significant collections of Sargent's watercolors.
Contemporary watercolorists who specialize in landscape and atmospheric effects often prefer rough paper. The Artists and Illustrators guide recommends rough paper for landscapes and seascapes, noting that the texture allows pigment extra drying time and creates natural textural effects that suit outdoor subjects.
Rough paper is the most textured of the three standard watercolor surfaces. Cold pressed is moderately textured, the most popular choice for general watercolor work. Hot pressed is smooth, chosen for fine detail and botanical illustration. Rough paper is the specialty surface for expressive, textural, and atmospheric work where the surface itself becomes part of the image.
The trade-off with rough paper is detail. Fine lines are difficult because the brush skips across the peaks. Botanical illustration is nearly impossible on rough paper. Portraits and architectural subjects that require precision are better suited to cold pressed or hot pressed. But for landscapes, skies, water, and any subject where texture and atmosphere matter more than precision, rough paper is the best choice.
Rough paper rewards loose, confident brushwork and punishes fussy detail. Work with larger brushes and broader strokes. Let the texture of the paper create the effects rather than trying to control every mark. For skies, a single wash on rough paper will produce more atmospheric variation than multiple layers on a smoother surface. For rocks and terrain, dry brushing on rough paper creates natural texture without effort.
Rough paper is available in the same weights as other watercolor papers. 140 lb (300 gsm) is standard, though the heavy texture can make the paper feel more substantial than cold pressed at the same weight. 300 lb (640 gsm) rough paper is also available and is particularly good for large-scale landscape work because it does not require stretching.
