If you only buy one sketchbook, the question isn't "which is best" — it's "which handles the most without falling apart," and that's the Strathmore 400 Mixed Media. At 140 lb (300 gsm) it's roughly twice the weight of a standard sketch pad, which is the whole point: a marker layer won't ghost through to the next page, and a light watercolor wash won't turn the sheet into a wavy mess.
The trade-off is that it's a generalist. A dedicated watercolor block holds standing water better, and a smooth bristol takes a cleaner pen line. But for the artist who sketches in pencil, inks over it, drops in a wash, and finishes with a marker accent — all on the same spread — nothing else here keeps up as gracefully.
Our Pick
The book that does everything well enough. At 140 lb (300 gsm) with a vellum surface, the Strathmore 400 Mixed Media takes pencil, ink, marker, and light washes on one page — the most forgiving all-rounder for an artist who switches between dry and wet in the same sketch.
Buy this if you don't want to own four sketchbooks. It's heavy enough that a watercolor wash or a marker layer won't buckle or bleed through the way it would in a thin sketch pad, and the lightly textured vellum surface still feels good under graphite and pen. If you work loosely across media, this is the one book to keep on the desk.
What we don't like
It's a true jack-of-all-trades, master of none. Heavy watercolor work will still cockle the sheet (a dedicated 140 lb cold-press watercolor book holds water better), and the surface is too toothy for the smoothest pen-and-ink line work. The tape-bound pad isn't as durable to carry as a hardcover.
