Size, configuration, expandability, and portability are all issues unique to each drummer that must be considered when choosing a drum rack. It must be strong enough to support the weight of an entire drum kit and stable enough to stay upright during use. Research the manufacturer's reputation before purchase to ensure quality craftsmanship. Replacement parts should be readily available and the manufacturer should offer a good warranty that promises to repair or replace any defective items for the purchaser.
Drum racks are favored by drummers who desire greater stability and easier set up for their drum sets, and also want a smaller overall footprint. Extra floor toms, rack toms, cymbals stands, and percussion instruments can take up a great deal of space and require too much time to both set up and take down. Depending on the drummer's playing style, these items may also have a tendency to creep across the floor due to vibration which requires readjustments that might be difficult during a live performance. Gigging drummers with larger kits have longer set-up and tear-down times with individual components versus using a drum rack.
Most drum racks are made of tubular steel and are very strong. They usually have rubber bumpers on the feet to reduce creeping during drumming, but it's still recommended to put the drum rack on a drum rug to help keep everything in place. Some drummers have a strong playing style and hit their drum kits with force, causing the entire kit to vibrate and slide away. A drum rug will help to reduce vibration issues as well as giving drum pedals something to anchor to.
A musician with a modestly sized drum set who isn't interested in drum kit expansion will want a preconfigured drum rack kit that includes all the necessary pieces like clamps and arms. A drummer who is just starting out or who is looking to expand in the future but is on a tight budget, will want to buy a drum rack a piece at a time. Many drum rack manufacturers offer expandable drum racks that can support additional pieces to accommodate floor toms, extra snare drums and cymbals, or other percussion instruments. Additional pieces can be bought over time and added to the drum rack as needed. Custom drum racks are available for those with specific needs or unusual drum set configurations.
