If you want a backboard for indoor and outdoor use, it’s best to consider getting tempered glass, acrylic, or fiberglass. While fiberglass isn’t as durable as other plastic-based materials, they’re a great substitute for those on a budget and still want to shoot good hoops.

The following is the typical selection of materials you'll see for backboards that are best for outdoor basketball hoops: Polycarbonate: This type of backboard is durable and made for the outdoors. Weather will least affect this type of backboard. Acrylic: These have the look of a glass backboard, but are less expensive and much more lightweight.

For professional basketball, tempered glass is the best option, but it is also the most expensive. Acrylic is the best option if performance is still very important but you are a bit constrained by the budget. If durability and budget are the main points, steel backboards are your best choice.
