There is no single standard for mahjongg dimensions. Most mahjong tiles stand about 30 to 40 mm tall (1.2 to 1.6 inches). A square table around 36 inches wide suits most American games.
This guide covers mahjongg tile size, set size, table size and space. It also explains the online 3D Mahjongg Dimensions game.

Mahjongg Tile Sizes: Standard Dimensions in Inches and mm
Sizes vary by maker, so treat these numbers as typical ranges, not rules.
Tile style
Height × Width × Thickness (mm)
Inches
Chinese (common)
32 × 22 × 14 mm
1.26 × 0.87 × 0.55 in
American (mid)
35 × 25 × 19 mm
1.4 × 1.0 × 0.75 in
American (large)
38 × 28 × 19 mm
1.5 × 1.1 × 0.75 in
Compact American
30 × 22 × 13.5 mm
1.18 × 0.87 × 0.53 in
Most Chinese sets use tiles of about 30 to 34 mm, while American sets often use 38 to 40 mm. Mid-size examples also appear in published tile guides.
Tile Height, Width and Thickness
Height is the long side of the tile face. Width is the short side. Thickness is the depth from face to back. Always check all three before you buy a rack, pusher or case.
Why American and Chinese Tiles Differ
American tiles sit on racks, so makers can build them thinner. Chinese tiles stand on their own to form the wall, so they are often thicker. A tile near 15 mm thick may not fit a standard American rack rail.
How to Choose the Right Mahjong Tile Size
Larger tiles are easier to read. Smaller tiles are easier to shuffle and carry. Pick the size that fits your hands, your eyes and your table.
Mahjongg Set Size: Tile Count, American vs Chinese
A traditional Chinese Mahjong set has 144 tiles. American Mah Jongg adds 8 jokers, which makes 152. Many modern American sets sell with 166 tiles, which include extras.
What Is in a Mahjong Set?
A standard set holds three suits (dots, bamboo and characters), winds, dragons, and flowers and seasons. American play adds jokers.
Racks, Pushers and Dice
American sets usually come with racks and pushers. These add to the footprint. Chinese sets often come with dice and a wall of tiles only.
A mahjong table is usually square, with one player per side.
Table type
Typical size
Chinese tabletop
28 to 35.4 in
Standard American
36 × 36 in
Standard square
32 or 36 in
Large square
40 or 48 in
Automatic table
38 to 48 in
These figures come from published table-size guides and maker charts.
Match the Table to Your Tile Size
Bigger tiles need a bigger tabletop. As a guide, tiles near 1.4 inches suit a table of about 34 inches.
How Much Space Do You Need to Play?
Count the table first, then add room for chairs. A common rule of thumb is to leave about 36 inches between the table edge and the wall. A 36-inch table plus 36 inches on each side is roughly 9 × 9 feet (108 inches).
A mahjong mat also helps. It muffles noise and protects the tiles.
Mahjongg Dimensions Game: 3D Board and Tile Layout
Mahjongg Dimensions is also a free online 3D game. It turns the classic tile-matching puzzle into a rotating cube.
How the 3D Board Works
You match pairs of identical tiles to clear the board. A tile is free when it has open space on its left or right side. Rotate the board by swiping, or with the arrow keys, to reveal hidden tiles.
Tips for Playing 3D Mahjong
Rotate often to uncover blocked tiles.
Free blocked tiles first to create more options.
Use Shuffle once. It works only once per level.
Watch the timer. A typical level gives you 350 seconds.
Chase combos. A speed bonus rewards quick matches, and a pattern bonus rewards matching the same tile twice in a row.
A harder version, Mahjongg Dark Dimensions, adds Time Bonus Tiles that keep the clock running.
