I thought it would be of interest to present the data relating to the longitudinal lengths (along the ecliptic) of the 12 starry zodiacal constellations: this data (taken from Robson and from Clerke) shows that the constellations are of unequal length, and that the total degrees (of longitude) add up to 415, which is 55 degrees more than the total degrees of the ecliptic circle (= 360);so the various constellations overlap each other in many cases.
(In order to prevent confusion between zodiacal constellations and zodical SIGNS, which are 2 different things, I will be using the latin names for the starry zodiacal constellations)
+Arietis: 33 deg. (in longitudinal length along the ecliptic)
+Tauri: 37 deg.
+Geminorum: 23 deg.
+Cancri: 26 deg.
+Leonis: 41 deg.
+Virginis: 47 deg.
+Librae: 22 deg.
+Scorpii: 34 deg.
+Sagittarii: 34 deg.
+Capricorni: 28 deg,
+Aquarii: 48 deg.
+Piscium: 42 deg.
