Racks & pushers, explained
What racks actually do
In American mahjong your rack holds your hand upright and hidden, and its pusher slides your exposed wall outward at the start and during play. A rack that is too short for your tiles, or a pusher that binds, taxes every single hand — racks are per-game equipment, not storage.
The three families
All-in-one plastic rack/pushers (included with most complete sets) are light and foolproof. Wooden racks (Linda Li's beechwood, Crisloid's cherry, YMI's wooden-case sets) add weight, stability and looks. Clear acrylic racks (sold by the designer brands) disappear visually so the tiles carry the table — the aesthetic choice, at a designer price.
Size to your tiles
Racks are built for standard American tiles (about 1.25 in). Enlarged tiles and many vintage tiles stand taller and may not sit correctly in a standard rack's lip. If you buy oversized tiles, confirm rack fit with the seller before the game night, not during it.
What four should cost
Expect roughly $40–$70 for serviceable all-in-one sets, $80–$150 for wooden, and designer acrylic at the top of that range and above. If a tiles-only set tempts you, add the rack set and a mat to the headline price before comparing it with a complete set — that honest total is the comparison this site prints on every product.
