Mask size measurements/experience of others

So I just recently purchased my first nag from Niko’s art gallery And I’m super pumped but I’ve got to ask people on here from their experience. How do you choose your mask size when you order one? I measured my forehead at the brow line above the ears all the way around for a 24-in measurement on the money. Since Nik is the professional here I let him know that was my measurement and asked his opinion and he recommended a 25.5 inch mask for a 24-in head. Curious what others out there have gone with as far as how much bigger than their personal measurement they’ve went. I spent some time trying to figure out the measurement of the tots Halloween kills mask because that was hands down the best fitting mask I’ve ever worn it was loose but not too loose and very comfortable. I heard many different things seem like the most consistent was 24 and a half or 25 for that mask but anyways was curious what others have gone with after taking their personal measurement
