At 9.75" x 3.27", the Amazon Echo stands just a bit bigger than a couple cans of soup. (And significantly smaller than the last black cylinder we tore down, the Mac Pro).

Lifehack: While you're waiting for Amazon to decide to let you buy an Echo of your own, use soup cans to test out where you might put it in your home. Then ask it to do your homework. Have fun!

Echo's model number lives in its rubber foot: SK705DI.
