Room for Squares is the debut studio album by American singer-songwriter and guitarist John Mayer, originally released on June 5, 2001, and re-released on September 18, 2001, by both Aware and Columbia Records.

[11] As part of the major label "debut", the album's artwork was updated, and the track "3x5" was added, which did not appear on the original as the recording was not yet complete at the time.

The album was relatively unknown at its time of release, but it became more well known through word of mouth and John's touring,[8] and reached number one Billboard's Heatseekers chart by March 2002.

[13] By the end of that year, Room for Squares had spawned several radio hits, including "No Such Thing", "Your Body Is a Wonderland", and ultimately, "Why Georgia" (a radio-only single).

By April 2002, Room for Squares had seen increases in eight of the previous nine weeks, earning the Billboard 200's Greatest Gainer (from number 82 to 56)—a 36 percent surge.

[22] The increase was attributed to combination of a March performance of The Tonight Show With Jay Leno and the radio-and-retail campaign launched in more than 10 markets where Mayer was receiving airplay.
