Photometric redshift errors spread galaxies along the line of sight over distances comparable to the size of voids. We extend the theoretical model of the void size function to include this effect, as a damping of the variance of the density field, and we test it on AbacusSummit halo lightcones with mock photometric redshifts. This is a first step towards modelling voids in LSST and Euclid.
