6-inches tall. Originally retailed for around $150.

The back of the box has the following text:

A Mandalorian bounty hunter without equal. Though technically a clone of Jango Fett, he is one-of-a-kind in his ability to do his job. By capturing Han Solo and his friends, he collected two bounties for the same haul - one from the Empire and one from Jabba the Hutt. Unfortunately, he will meet with quite the grisly fate in the maw of the Sarlacc.

* Note that in the current canon, Boba Fett is not Mandalorian and he's neither dead nor alive after falling in the Sarlacc.
