Abstract: (Elsevier)

We demonstrate that Poincaré invariant quark models of the pion can give charge form factors in agreement with all available data. The quark-antiquark model wave functions are spin-zero eigenfunctions of the four-momentum. The relativistic features of the model are essential for the result. The confinement scale is much smaller than the charge radius.
