An acrylic basketball backboard is a sheet of 12 to 19 mm cast acrylic chosen for one property that glass does not have: it does not shower the court when it breaks.
A sports hall in Rotterdam replaced eight glass backboards after a single season of rim hangs. The acrylic panels fitted that summer are still in service four years later, with two surface scuffs and no replacements.
Acrylic basketball backboard sheet and face size
- Face size: 1800 x 1050 mm, regulation
- Thickness: 12 mm school, 15 to 19 mm arena
- Rim mounting: 225 mm above the bottom edge
- Bolt holes: 2 mm oversized, nylon washers
The panel is the visible part, and the frame behind it decides whether the panel survives. A backboard bolted flat against a wall with four corner bolts will flex at the rim and crack within a season; a stiffener frame with a perimeter channel and a rim brace takes the load instead.
Fixing detail and the rebound question
Bolts need clearance and isolation. A 12 mm hole in a 12 mm panel leaves a thin ring that acts as a stress raiser, and a rim hang lands directly on it. Drill 14 mm, fit a nylon washer under the head and a rubber gasket between panel and frame, and the same panel handles the same abuse.
Rebound feel is a real specification, not a marketing line. Coaches notice a panel that is too thin because the ball dies on contact and the shot comes off flat. Thickness gives the stiffness that returns energy to the ball.
For the cut list and drilling of the sheet itself, the acrylic cut to size service covers tolerance and edge finish, which matters on a panel seen from both sides.

Frequently Asked Questions
What thickness acrylic basketball backboard for a school court?
12 mm clear cast is standard for indoor school courts up to 1800 x 1050 mm. Competition arenas use 15 to 19 mm because the rebound feel and the resistance to rim flex both come from thickness.
Why does a backboard crack at the bolt holes?
Bolt holes drilled without clearance and without a rubber washer concentrate load on a 2 mm ring of material. A 2 mm oversized hole with a nylon washer spreads it and removes the failure mode.
Can an acrylic basketball backboard be repaired?
A crack can be stop-drilled and polished to keep a court in use, but rebound feel changes at the repair. Replacement panel is the permanent answer once a crack passes a bolt hole.
