As we learn

To study the effect of detergent on surface tension of water by observing capillary rise -

T = \left [ \frac{r\rho hg}{2\cos \theta } \right ]

T\alpha h

 h=\frac{2\: s\: \cos \: \Theta }{\rho \: r\: g}

\therefore h\; \alpha \; \frac{1 }{r}

If radius of capillary tube increases then its height will decrease.
