I’d hope your 7” travel would be counted the trailing edge of your body in the direction of travel front to rear, so a full 7”. Measured from shoetip start to heel end. Most walls in stickbuilt homes are only ~4 1/4” thick, you could teleport through those. If only from tip of shoe to tip of shoe, you’re right. You’d teleport inside your own space. Kinda useless.
