How Loud/obvious Is a Wizard Casting a Spell?

.. the particular combination of sounds, with specific pitch and resonance....Somatic (S)Spellcasting gestures might include a forceful gesticulation or an intricate set of gestures. ...This is all the detail we get from the rules. Clearly, gestures must be made and sounds must be produced, but the exact extent of beyond being audible and visible is not solidly layed out.It is worth noting that the rules do even say that there is a potential range of how obvious the somatic component might be, so it may even depend on the spell. Jeremy Crawford has shed some light on the intent for verbal components though (in an old unofficial tweet):The verbal component of a spell must be audible to work. How loud is audible? That's up to the DM.One thing is sure though: both the verbal and somatic components are definitely noticeable however. We know this because there is at least one class feature, a Sorcerer's Subtle Magic metamagic, whose only purpose is to make them not noticable:When you cast a spell, you can spend 1 sorcery point to cast it without any somatic or verbal components.

In the end, your DM will have to decide how they want it to work in their world

Some spells have somatic and vocal components, that's well known.

How loud must a wizard talk? How obvious/wide should his gestures be?

Some spells that would be awesome would be fairly limited if you need to shout them

(ex: mage hand, range 30ft).
