A floor tom is a double-headed tom-tom drum which usually stands on the floor on three legs. However, they can also be attached to a cymbal stand with a drum clamp, or supported by a rim mount. The floor toms are the lowest tuned drums played with sticks in the regular 5 piece drum set. Common sizes are

• 16x16, that is, in both depth and diameter. This was the original size and is still most common.
• x14 for jazz and fusion kits, and very occasionally with a 16x16 as well.
• 18x16; that is, in diameter and 16 in depth, the most common size for a second floor tom, used with a 16x16.
• 16x18, a rarer size sometimes used for a second floor tom, also with a 16x16.
