Fire doors use intumescent strips and these have to be taken into account when measuring, you cant have more than a 3mm gap around a fire door when it has been fitted this is about the width of a £1 coin. Make sure you take off 3mm each side and the top for your door size and you can have no more than a 10mm gap on the bottom of a fire door.
When you are measuring the door keep in mind how the door opens, stand in front of the door so that it opens away from you and look which side the hinges are left or right of the door, Left side hinges means door is left hand opening away, where as right side hinges is right hand opening away.
