^Correct.

When you choose to view the "full site" on a smartphone, you'll get the smallest fluid size (which is the tablet/portrait layout) since you're on a small display.

If you're being shown the Wikia skin on your smartphone by default (without choosing the "full site" option on the mobile skin), please write in via Special:Contact and let us know more details.
