Hattrick stadion calculator Usage: Type in a number in any of the fields. When leaving the field the information in the others will be updated. Total seats: Terraces (63%): Basic seating (23%): Seats under roof (10%): VIP boxes (2%): NOTE: Total seats will be corrected after rounding the other numbers so the total actually IS the sum of the others :-) This was not the case when I first made it. I take no responsebility for the use of this calculator - if you don't like it - don't use it!
