Hi, there is a formula that takes into account,windows and there insulation properties and position and also the volume of the room-you will need to get in a professional for this.
But as a rule any daily living space up to around 40sq ft will need no more than a double 800x600 rad,hallway 800x600 double bedrooms similar rule but single rads but also consider where they are in the room and the size of wall you want to attach them to.
Hope this helps
