Review: Top-tier quality for serious artists—my aunt was thrilled! - I purchased this 12" x 16" Arches watercolor block for my aunt, who is a very capable and experienced artist. She always strives for the absolute best in her artwork, so I knew I couldn't cut corners on her supplies. She was incredibly pleased with the overall quality and has gotten a lot of enjoyment out of painting on it. When it comes to watercolor suitability and overall durability, this heavy 300-pound paper is unmatched. It handles heavy water washes beautifully without warping or buckling. She specifically praised the texture—the cold press surface provides the perfect amount of tooth for her paints to grip, giving her precise control over her brushstrokes. Another huge plus is the portability. Because it is a glued block, she doesn't need to tape down loose sheets to a separate heavy drawing board. She can just grab the block and easily travel or paint outdoors, knowing the glued edges will keep the sheet perfectly taut while she works. If you are buying for a dedicated painter who demands professional-grade results, you really can't go wrong with Arches. Even though it is a premium product, the flawless performance and lack of frustration make it an outstanding value for money. Seeing how happy she is with it makes this an easy 5-star purchase!
Review: Very Absorbent Paper - I love this paper. However, for the first time, the whole block of paper came away from the cover. It just wasn't glued well.

## Features

- Prized Paper - The long fibers in Arches natural white 100% cotton watercolor paper provide timeless beauty and an inimitable touch; this rich paper is available in 13 sizes and 3 revered textures: cold press, hot press and rough
- Superior Strength - A cylinder mold process distributes cotton fibers evenly to provide exceptional resistance to scratching and erasing without tearing or linting; it allows our heavyweight cold pressed watercolor paper to slacken uniformly when wet for outstanding control
- Exquisite Quality - Glued on all sides to preserve paper integrity, Arches cold press watercolor block boasts a protective cover sheet and pH-neutral paper with a harmonious natural grain and no optical brightening agents
- Exclusive Gelatin Sizing "to the Core" - Arches watercolor paper is the only art paper in the world to be gelatin sized "to the core"; it increases the luster and transparency of colors while preventing paints from penetrating into the paper and makes blending, overlay or paint removal easy, wet or dry
- Premium Art Papers Since 1492 - After five centuries, the Arches philosophy remains the same: to make the best papers and enable you to produce your finest works while guaranteeing they will last as long as our papermaking heritage

## Questions & Answers

**Q: what is the larges sized block of 300 pound, cold pressed?**
A: I believe it is 10 X 14 inches.  That is the largest arches 300 lb watercolor BLOCK paper pad I’ve seen.

**Q: Can both sides of 300lb cold-pressed paper be used for Watercolor?**
A: Yes! Whatever side of paper of the paper you prefer. 300lb. Water color paper is quite heavy so less likely to buckle.

**Q: Is the block white or black?**
A: The block is white

**Q: How thick (NOT weight) is each sheet in inches or mm?**
A: This is 300 lb water color paper. It isn't measured in thickness, whether inches OR millimeters. It is just as thick (or just as thin) as all other 300 lb watercolor paper. The only way to tell how thick a sheet is would be to put a micrometer on it. All that said, it is not _very_ thick--perhaps about as thick as stiff poster board.

### ⭐⭐⭐⭐⭐ Highest quality
*by S***B on May 3, 2026*

Arches is always highest quality. It arrived OK, but I am becoming more and more concerned about Amazon's shipping practices using materials that don't protect vulnerable products as well as they used to.
