Plan for a 16.72-inch row.
The listing gives a tile width of 0.88 inch. Nineteen tiles at that width span 16.72 inches before extra room.
That figure is the row length from the listed width. It does not confirm that any specific rack’s usable ledge is long enough.
What the item page lists.
The Hobby Lobby mahjong set page lists 152 tiles at 1.16 × 0.88 × 0.56 inches, three dice, a wind indicator, 80 chips, and instructions. It does not name racks or a mat in its listed contents. Check the box and current item page for the exact variation you are considering.
If you already own a rack, measure the ledge where tiles rest and enter it in the rack fit calculator. A rack’s outside length is not the usable length.
Can the set work for American play?
The listing total is 152, which matches the American reference total, but count the groups and inspect the faces before relying on it. The American inventory includes eight jokers and eight flowers. Use the tile count checker and confirm the game with your host.
No mat is named in the listing. If your set includes one, measure its full footprint against the table with the mat fit calculator.
Other named checks: Costco, Sam’s Club, Target, and Yellow Mountain Imports.
