Large-basis meson wave functions, built from static cavity quarks and gluons, are used in conjunction with a simple plane-wave projection prescription to calculate meson charge radii with /ital O/(/ital g//sup 2/) corrections. After fitting to the light-meson mass spectrum the pion charge radius is used to constrain the remaining degree of freedom of the model parameters. The resulting large-basis model is found to give the following mass predictions in the light-quark sector: /ital K//sup */(892)=904.4/plus minus/0.1 MeV, /phi/(1020)=1040.6/plus minus/0.1 MeV. For the kaon charge radius we obtain /l angle//ital r//sup 2//r angle//sub K/=0.35/plus minus/0.040 fm/sup 2/ (/l angle//ital r//sup 2//r angle//sub K//sup expt/=0.34/plus minus/0.05 fm/sup 2/).
