TARDIS stands for Time And Relative Dimensions In Space, and is composed of many more dimensions (5th, 6th, 7th etc) - so you're incorrect to say it is in "4 Dimensions". It is actually possible for a TARDIS to be larger outside
than it is inside, assuming that the chameleon circuit diguises itself as a big enough object (one with a larger volume than the interior of the TARDIS).
As it happens, the Doctor's TARDIS (which he stole) has a malfunctioned chameleon circuit, meaning that it's always a police call box. Other Time Lord's TARDISes adapt to their surroundings (The Master's TARDIS for example, took the form of a beach hut when he materialised on the coast).
It's worth bearing in mind that the TARDIS interior always changed after the Doctor regenerated, so the interior size varied from Doctor to Doctor.
But I'm not a die hard fan of Doctor Who. No sir.
