A range from C3 to G5 covers 2.5 octaves, which is healthy for an untrained adult singer. But "what voice type does this range suggest?" is more nuanced than a simple lookup — because absolute range is one input, and tessitura (where you sit comfortably) is the other. The same C3-G5 range can be a mezzo with strong upper extension, a tenor with developed head voice, or a flexible alto.
C3 (the C below middle C) is a comfortable bottom note for tenors, baritones with reliable bottom, and altos. It's a stretch for sopranos and mezzos, who typically don't need to descend that low in their repertoire.
G5 (the G in the top space of the treble clef staff) is a comfortable top for sopranos and trained mezzos with strong upper extension. It's the upper limit for many altos and beyond the typical reach of male voices in full voice (though falsetto can extend there).
Combining the two: a singer with a comfortable C3-G5 range is most likely (a) a mezzo-soprano with developed lower extension, (b) an alto with developed upper extension, or (c) a male singer who can access head voice through G5 (in which case the G5 is in head voice / falsetto, not full voice).
What does C3-G5 actually mean for your voice type?
Confirm both ends are *comfortable*, not just reachable. Sustain C3 for 4 seconds — does it have full tone? Sustain G5 for 4 seconds — same question.
For each end, identify whether the comfort is in chest voice or head voice. C3 should be chest. G5: chest = mezzo or trained alto with belt; head = the more common case for either gender.
Identify the tessitura — pick a 4-bar passage and figure out which 5-note span you sit in most easily. Mezzo tessitura: D4-D5. Soprano: F4-F5. Alto: G3-G4. Tenor: D3-D4 (in chest) or A4-B4 (in head).
Run the free Range Test below. It reads your full range and tessitura in 60 seconds and gives you the classification with mathematical precision.
Generic "voice type calculators" online often classify based on absolute range alone, which produces wrong answers for any singer with developed extensions. A real classification needs both range AND tessitura, which only a real-time pitch-tracking test can give.

If you want to expand range further, the daily app has range-extension drills that target specific gaps. Realistic timeline: 3-6 months of consistent daily practice for 1-3 added half-steps; 12+ months for a full added octave (and a 12-month gain is rare).
