Leuchtturm1917 Master A4 Hardcover Sketchbook - Thick 150 gsm Paper

In this review of the Leuchtturm1917 Master A4 Hardcover Sketchbook the bottom line is simple: this is a solid, no-nonsense sketchbook for artists who need thick, inkproof paper in a large format. The reviewer found the 112 pages of 150 g/m2 paper and the A4+ size especially useful for loose studies, figure work and mixed-media sketches where bleed resistance and a sturdy spine matter. Practical extras like two ribbon markers, a gusseted pocket and adhesive index labels make it feel more like a well-considered notebook designed for an artist's workflow.

Key Features

• 150 g/m2 inkproof paper: Thick paper that reduces show-through and stands up to pencil, charcoal, chalk and many wet inks for confident layering.
• Large Master A4 size: Roughly 8.85 in by 12.4 in gives noticeably more drawing room than a medium pad for compositions and detailed work.
• 112 pages: A substantial page count that balances permanence with portability for extended projects or archival sketching.
• Practical built-in extras: Two ribbon page markers and a gusseted inner pocket keep reference material and marked pages organized without additional accessories.
• Indexing labels: Self-adhesive labels for cover and spine make it easy to catalog volumes and locate work quickly on a shelf.

Who It's For

The sketchbook suits illustrators, sketching students and mixed-media artists who value heavy, mostly inkproof paper and a larger surface for composition. Those who like to glue in clippings or paste light collage materials will appreciate the sturdiness customers reported when affixing extra pages.

Artists who work exclusively with very wet markers or heavy alcohol-based pens and expect zero bleed may want to test the paper first or consider specialised marker pads, since some customers noted occasional marker bleed-through with the heaviest inks.

Pros & Cons

Pros

• Paper quality and texture are consistently praised and handled pencil, charcoal and many inks well.
• Large A4 format gives ample space for detailed studies and broader compositions.
• Durable construction with hardcover, two ribbons and a gusseted pocket enhances everyday usability.
• Includes adhesive labels for neat archiving and spine identification.

Cons

• A minority of users report bleed-through with certain markers, so very wet or alcohol-based markers may not be fully contained.
• The hardcover Master format is larger and less pocketable than A5 options if portability is a priority.
