Mezzo-soprano vocal range: A3 to A5
The mezzo-soprano range runs roughly A3 to A5 — about 2.0 octaves — and here is how to tell whether it is actually yours.
The range
A mezzo-soprano sits at roughly A3 to A5: 24 semitones, or about 2.0 octaves. These are comfortable working ranges rather than the extremes a trained singer can reach on a good day, which is the distinction that matters when you are trying to place your own voice.
The most common female voice type, sitting between alto and soprano, with a full middle and a usable top. Most pop singers described as sopranos are mezzos.
How voice type is actually decided
Voice type is not the same question as highest note. It is decided mainly by tessitura — the part of the range where the voice is comfortable and sounds best over a whole song — and secondarily by timbre and by where the register transitions fall. A range measurement narrows the answer; it does not settle it.
sentivoice classifies a measured range by comparing its midpoint against each type's midpoint and taking the nearest. That is a rough self-classification and it is meant as one: it is good enough to tell you what key to try a song in, and it is not a conservatory placement.
What people get wrong about it
The mezzo range overlaps both neighbours heavily, so a range measurement alone will not settle it. Where the voice is most comfortable — its tessitura — separates a mezzo from a soprano far more reliably than the highest note either can hit.
What to sing
Almost all commercial female pop is written for this range. It is the safest default for a singer who does not yet know their type.

What is the mezzo-soprano vocal range in notes?
Roughly A3 to A5, which is 24 semitones or about 2.0 octaves. Individual singers vary in both directions, and the working range that a singer can use for a whole performance is usually narrower than the total range they can produce.
Can my voice type change?
The comfortable range can shift with training, age and health, and it usually widens at the top with technique. Wholesale reclassification is uncommon in adults. Adolescent voices are a different matter and are still settling.
How do I measure my own range?
Sing down from a comfortable note until the tone stops being usable, then up the same way, and record the lowest and highest notes you could actually hold — not the ones you could just about produce. sentivoice runs this as a guided in-browser test using your microphone.
