It's hard to pinpoint measurements anywhere. When putting in my air vent through the roof it came out in an unexpected area in my ceiling inside 😝 Also the notches on my bed didn't line up with my bunk frame like I intended though luckily everything still worked well enough 👍 not everything is gonna be perfect all the time. Sometimes you gotta take the good with the bad and that's alright to.
