The pairing effects on the $g$ factor of chiral doublets in the $\pi {\left(1h_{11/2}\right)}^1\otimes \nu {\left(1h_{11/2}\right)}^{-1}$ configuration are investigated using the particle rotor model. The results show that the $g$ factors of yrast and yrare bands decrease with increasing neutron pairing gap ${\mathrm{\Delta }}_n$. At the bandhead ($I=9\hslash$), the $g$ factor is decreasing for the yrast state and increasing for the yrare state as the triaxial deformation parameter $\gamma$ increases. The $g$ factor varies with spin $I$ based on $\gamma$: for $\gamma <{30}^{\circ }$, it increases then decreases; for $\gamma >{30}^{\circ }$, it decreases then increases. A kink in the yrast band's $g$ factor may signal aplanar rotation. These trends are linked to the proton (${\mathit{j}}_p$), neutron (${\mathit{j}}_n$), and total ($\mathit{I}$) angular momenta and their effective angles ${\theta }_{pI}$ and ${\theta }_{nI}$. An increase in the short (long) axis component of $\mathit{I}$ reduces ${\theta }_{pI}$ (${\theta }_{nI}$), increasing (decreasing) the $g$ factor with spin. Moreover, the ${\theta }_{nI}$ is reduced by ${\mathrm{\Delta }}_n$ and results in smaller $g$ factor.
