Summary: The commutators of standard Virasoro generators and fields generate various representations of the centreless Virasoro algebra depending on a conformal dimension \(J\) of the field in question (\(J\) is related to the Bargmann index of SU\((1,1)\) generated by \(L_m, m=0,\pm 1)\). We introduce the notion of \(q\)-conformal dimension for various oscillator realizations of \(q\)-deformed Virasoro (super)algebras proposed earlier. We use the field theoretical approach introduced recently in which the \(q\)-Virasoro currents \(L^{\alpha } (z)\) are expressed as Schwinger-like point-split normally ordered quadratic expressions in elementary fields. We extend this approach and probe the elementary fields \(A(z)\) (the \(q\)-superstring coordinate, momentum and fermionic field) and their powers by the \(q\)-Virasoro generators \(L^{\alpha}_m\) (i.e. we calculate the commutators \([L^{\alpha}_m ,A(z)])\) and show that to all of them can be assigned just the standard non-deformed conformal dimension.
