Practice Sketching
For rough practice sketches, pretty much any paper will do. Office printer paper is cheap and smooth and doesn’t “bleed” if you like to sketch in pen. Bulk newsprint pads are functional, if not robust, and useful for large preparatory sketches. Canson Biggie Sketch or Strathmore 200 series are good, economical choices.
Expressive Sketching
Expressive sketching calls for paper with a slightly rougher texture. Generic sketchbook paper has a fibrous texture that allows specks of white to show through the shading and a toothy surface that will hold onto the softest of mediums. Try the 80-pound Blick Drawing Pads or Canson Heavyweight Sketch.
Detailed Sketching
For sketches with a little more detail, a better quality sketch paper will give you a finer surface to work on. Strathmore Windpower Sketch is a lightweight (almost transparent) paper with a fine smooth surface, while Windpower Drawing is a little heavier.
Paper Surface and Texture
The surface of the sketch paper shouldn’t detract from a sketch, but it often doesn’t add anything, either. If you want a stronger texture through your sketch, consider a medium-surface drawing paper such as Lana Dessin. The double sizing gives a firm drawing surface while the even grain gives sketches a distinctive look. For sketches with a classic parallel-line texture running through them, try a traditional Laid paper, such as Canson Ingres or Hahnemühle Ingres.
