The gladius has been measured at 18.8 inches overall (see here), although the measuring techniques are somewhat imperfect. The blade alone of a gladius hispaniensis should be 24-27 inches, according to the source Sarcasm posted (which I use as well).

Thanks for the link, Simetrical: fascinating stuff. Interesting to know that elephants should be even more impressive than they are now!
