We apply the large-charge expansion to 0(N) vector models starting from first principles, focusing on the Wilson-Fisher point in three dimensions. We compute conformal dimensions at zero and finite temperature at fixed charge Q, concentrating on the regime 1 << N << Q. Our approach places the earlier effective field theory treatment on firm ground and extends its predictions.
