A full-size marble board doesn't fit every table — the 12-inch marble chess set is built for the ones it doesn't. Every set in this collection has a 12" × 12" board with 1-inch squares and a 2.75-inch king, weighing about 7.3 pounds in solid natural stone. That's real stone weight in a board that fits a side table, a shelf, or a smaller room, and is light enough to move around easily — the most compact, space-saving way to own a marble chess set.

Each 12-inch 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. It's the same craftsmanship as the larger boards, scaled down for tighter spaces. Want more presence and a bigger board? See the 15-inch marble chess sets.

12 Inches Chess Sets

What you get in a 12-inch marble chess set

Every 12-inch set in this collection shares the same compact build:

  • 12" × 12" board with 1-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 2.75-inch king, down to 2-inch pawns — full playing scale for the smaller board.
  • About 7.3 pounds of solid natural stone — a third of the weight of the 15-inch set.
  • Piece-replacement service, free US shipping, and 30-day returns.

The 12-inch board is the practical choice when space or weight matters: it fits where a full-size board would crowd the room, it's easy to move and store, and it's the closest thing to a portable stone chess set.

Is a 12-inch chess set the right size for you?

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

 

The honest guide: 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. Choose 15-inch if you have a dedicated spot and want the fuller presence and playing feel of larger pieces. Both are complete 32-piece stone sets — the difference is size and weight, not quality. One trade-off to know: the 12-inch board's smaller squares and 2.75-inch pieces feel less commanding than the 15-inch set, which some players prefer for a serious game — but for most homes, and especially for tighter spaces, the 12-inch is the easier fit.

About 12-inch marble chess sets

RADICALn 12-inch marble chess sets are the compact boards in the range — 12" × 12" with 1-inch squares, a 2.75-inch king, and about 7.3 pounds of solid, hand-carved natural stone. The collection covers the classic black-and-white plus a wide range of natural stone colors, from translucent green onyx to warm coral and red, all at the smaller board size that fits tighter spaces. 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 color above, compare with the 15-inch sets, or return to all marble chess sets.

Frequently Asked Questions

The board is 12 by 12 inches with 1-inch squares. The pieces run from a 2.75-inch king down to 2-inch pawns, and the complete set weighs about 7.3 pounds in solid natural stone — the compact size in the range.
No — it's a full 32-piece set at full playing scale for its size, with a 2.75-inch king. It plays perfectly well for adults; the pieces are just smaller than the 15-inch board's. If you want the most commanding board for serious play, the 15-inch is larger — but the 12-inch is a proper, playable set, not a toy.
Choose 12-inch for smaller spaces or easy moving; choose 15-inch for presence and a dedicated spot. The 12-inch board (1-inch squares, 2.75-inch king, ~7.3 lb) fits tighter spaces and is lighter; the 15-inch (1.5-inch squares, 3.5-inch king, ~17 lb) has more weight and command.

Compare the 15-inch sets if you're unsure.
About 7.3 pounds for the complete set — board plus all 32 pieces. That's roughly a third of the weight of the 15-inch set, which makes it much easier to move and store.
It's the most portable option in the range at about 7.3 pounds — light enough to move room to room or take to a friend's. That said, it's still solid stone, so it's best carried with care and the pieces stored protected rather than loose. If you want the set to pack into a fitted case, see the sets with storage.
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 2.75-inch king down to 2-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 coral & red or fossil coral bring warm, unusual tones. Every set is the same compact 12-inch board in natural stone, so whichever you choose is unique to you.
Yes — that's exactly what it's for. At 12 inches it fits a coffee table, a side table, or a shelf where a 15-inch board would crowd the space, and it's light enough to move out of the way easily. It's the size to choose when space is the deciding factor.
Yes. Every 12-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.
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 store the pieces protected so edges don't chip.
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.
