As with most saxophones, the alto's written range is B{{music|flat}}<sub>3</sub> to F<sub>6</sub> (or F{{music|sharp}}<sub>6</sub>),<ref>{{cite web|url=http://library.thinkquest.org/5116/saxophone.htm|archive-url=https://web.archive.org/web/20090317103509/http://library.thinkquest.org/5116/saxophone.htm|archive-date=2009-03-17 |title=Range of the Alto Saxophone |publisher=Library.thinkquest.org |access-date=2011-01-18}}</ref> with the higher [[altissimo]] register starting at F{{music|sharp}}<sub>6</sub> (or G<sub>6</sub>). The saxophone's altissimo register is more difficult to control than that of other woodwinds and is usually only expected from advanced players. There is no well-defined upper limit for the altissimo register, but most fingering charts go up to a written D<sub>8</sub> (sounding F<sub>7</sub>).

The alto saxophone is a [[transposing instrument]], with pitches sounding a major sixth lower than written. In terms of concert pitches, the alto saxophone's range is from concert D{{music|flat}}<sub>3</sub> (the D{{music|flat}} below [[middle C]]—see [[Scientific pitch notation]]) to concert A{{music|flat}}<sub>5</sub> (or A<sub>5</sub> on altos with a high F{{music|sharp}} key).

A few rare alto saxophones, like some [[Selmer Mark VI]] models, have been keyed to reach a low A, a semitone lower, similar to [[Baritone Saxophones|baritone saxophones]].<ref>{{cite web|url=http://saxpics.com/model/14/Selmer-Mark-VI.html|title=The Selmer Mark VI|website=SaxPics|publisher=USA Vintage Horn Corp|access-date=2023-03-06}}</ref><ref>{{cite web|url=https://www.stohrermusic.com/2011/11/couesnon-low-a-alto-the-other-low-a-alto/|title=Couesnon Low A alto, the OTHER low A alto|website=Stohrer Music|access-date=2023-03-06}}</ref>
