The 15-inch marble chess set is the full-size board in the RADICALn range — the one with presence. Every 15-inch set has a 15" × 15" board with 1.5-inch squares and a 3.5-inch king, weighing around 17 pounds in solid natural stone, so it anchors a table, study, or display the way a smaller board can't. This collection gathers all of them: the classic and colourful standard sets, the sets that come with a fitted storage case, and the hand-carved antique and figurative designs — every one of them a full 15-inch board.

Each 15-inch marble chess set is a complete 32-piece set, hand-carved and hand-polished from natural marble or onyx, with an attached felt base and felt bottoms on every piece, backed by a piece-replacement service. If you have the space and want a board that stays out as a piece of décor, this is the size to choose. Prefer something more compact? See the 12-inch marble chess sets.

15 Inches Chess Sets

What you get in a 15-inch marble chess set

Every 15-inch set in this collection shares the same full-size build:

  • 15" × 15" board with 1.5-inch squares and an attached felt base.
  • 32 hand-carved Staunton pieces — 2 kings, 2 queens, 4 bishops, 4 knights, 4 rooks, 16 pawns — with individual felt bottoms.
  • A 3.5-inch king, down to 2.5-inch pawns — full playing scale with real weight in the hand.
  • About 17 pounds of solid natural stone.
  • Piece-replacement service, free US shipping, and 30-day returns.

The difference between the 15-inch and the 12-inch board is presence and play feel: the larger squares and taller pieces make the 15-inch set the more commanding one to sit down at, and the more substantial one on display.

Shop 15-inch marble chess sets by color

Because every board is natural stone, colour is where this collection has the most range:

15-inch sets with storage and antique designs

Not every 15-inch set is a plain board — some come with extras or in different styles, and they all live in this collection too:

  • 15-inch sets with a storage case — the same full-size board and pieces, with a fitted carry case that has an individual slot for every piece, so the whole set stores and travels together.
  • Antique & figurative 15-inch sets — hand-carved sets with detailed, characterful pieces for players who want the set to double as a sculpture.

If storage or an antique design matters more to you than size, those pages are the place to browse; if size is your first priority, everything on this page is a full 15-inch board.

Is a 15-inch chess set the right size for you?

15-inch (this collection) 12-inch
Board 15" × 15", 1.5" squares 12" × 12", 1" squares
King height 3.5 inches 2.75 inches
Weight ~17 pounds ~7.3 pounds
Best for Presence, display, dedicated table Smaller spaces, easy to move
Pieces Full 32, felt-backed Full 32, felt-backed

 

The honest guide: choose 15-inch if you have a dedicated spot for the board and want the fuller presence and playing feel of larger pieces. Choose 12-inch if space is tight, you want a lighter set to move around, or you're fitting it on a smaller table or shelf. Both are complete 32-piece stone sets — the difference is size and weight, not quality.

About 15-inch marble chess sets

RADICALn 15-inch marble chess sets are the full-size boards in the range — 15" × 15" with 1.5-inch squares, a 3.5-inch king, and around 17 pounds of solid, hand-carved natural stone. The collection covers the classic black-and-white, a wide range of natural stone colours, sets with a fitted storage case, and hand-carved antique and figurative designs — all at the larger board size. Every set is a complete 32-piece chess set with felt-backed board and pieces and a piece-replacement service, with free US shipping and 30-day returns. Browse by colour above, compare with the 12-inch sets, or return to all marble chess sets.

Frequently Asked Questions

The board is 15 by 15 inches with 1.5-inch squares, half an inch thick. The pieces run from a 3.5-inch king down to 2.5-inch pawns, and the complete set weighs about 17 pounds in solid natural stone.
Yes. The 15-inch board is the full-size option, with a 3.5-inch king and 1.5-inch squares — full playing scale with real presence on the table. It's the size to choose if you want a set that feels substantial to play on and looks like a proper board on display.
Choose 15-inch for presence and a dedicated spot; choose 12-inch for smaller spaces or easy moving. The 15-inch board (1.5-inch squares, 3.5-inch king, ~17 lb) has more weight and command; the 12-inch (1-inch squares, 2.75-inch king, ~7.3 lb) fits tighter spaces and is lighter.

Compare the 12-inch sets if you're unsure.
About 17 pounds for the complete set — board plus all 32 pieces. Sets that include a storage case weigh a little more with the case.
A complete 32-piece set — 16 per side: 2 kings, 2 queens, 4 bishops, 4 knights, 4 rooks, and 16 pawns. Heights run from a 3.5-inch king down to 2.5-inch pawns.
Start with colour: black-and-white is the timeless classic, green onyx is the most striking with its translucent glow, oceanic grey is calm and modern, and fossil coral is warm and unusual. Then decide whether you want a storage case or an antique design — both are available at this size. Every set is natural stone, so whichever you choose is unique to you.
Yes. Several 15-inch sets include a fitted carry case with an individual slot for every piece, so the board and all 32 pieces store and travel together. Browse them in the sets with storage collection — they're the same full-size 15-inch board with the case added.
Yes. The hand-carved antique and figurative sets are made at this size too — detailed, characterful pieces for players who want the set to double as a sculpture. See the antique & figurative collection.
Yes. Every 15-inch board has an attached felt base, and all 32 pieces have individual felt bottoms, so the set protects your table and the pieces don't scuff each other during play.
It's the best size for it. At 15 inches and around 17 pounds of natural stone, the board has real presence and stays out as décor between games. Because every board's veining is natural, it's also unique to you — a display piece as much as a game.
Wipe the board and pieces with a soft, dry or barely-damp cloth and keep the stone dry. Skip soap and abrasive cleaners, don't let liquids or acids sit on the surface, handle pieces by the body rather than the carved tops, and lift the heavy board rather than dragging it. That's all the upkeep it needs.
Yes — free US shipping, with a 30-day return policy. Marble ships in fragile-safe packaging, and if a piece is ever damaged, our piece-replacement service will source a matching one in the same stone.
