The general design followed that of Wibault's family of single and two seat fighters, the Wib 3, Wib 7, Wib 8 and Wib 9 but in external detail was closest to the Wib 8.
The general design of the Wib 13 followed the pattern set by Wibault's earlier single seat, parasol wing fighters, the Wib 3 and Wib 7 but it was smaller and lighter.
