With the spare tire out, a 6'2 inch, 215ish pound guy can fit in the frunk with the lid completely closed - and still have enough room to dial the phone and summon the wife to the garage to scare the crap out of her.
This led to the discovery that, should you find yourself locked in the frunk and there's nobody that cares within earshot, you can pop the frunk with your key and unlatch it from the inside quite easily.
I realize the dimensions I've provided may not be in the units of measure you find most useful...
