If you are replacing the doors in your property or as we say in your Kingdom, First rule is not to measure the door but the existing frame.
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.
Measuring the door
Take three measurement’s inside the door frame at the top middle and bottom the largest of the three is your door width.
Take two measurements on the inside of the vertical frame again for the door height, one either side remember to allow for any floor covering then measure the door thickness if you are keeping the frames you have and measure the rebate in the frame were the door sits when shut most standard door widths are 35mm or 40mm and if they are 44mm they will be fire doors.
