Consider the size of your yard when choosing a composter. If you have a small yard, but would like to compost kitchen scraps, choose a small bucket composter. If you have a large yard with a lot of grass clippings and yard waste, choose a large composter or build several compost boxes.
Decide whether you'd like to build a composter or buy a commercial model. Homemade composters are economical and versatile, but require some effort. They are generally durable and long-lasting. Commercial varieties often cost more and do require some assembly. They are usually made from plastic and vary in quality and durability. They offer the convenience of a ready-to-assemble kit.
Consider the size of the bin. To adequately heat up enough to break down yard waste, the composter should be at least 3 feet by 3 feet. Smaller bins may take a long time to decompose compost.
Look for a bin with ventilation holes. Compost needs good air circulation to break down properly. Also, consider how easy it is to access the composter to add materials, turn the compost and remove the finished product.
