When you measure for your radiator cover, you only need measure the following;

Length; measure the overall distance from outside valve to valve (this is probably wider than your actual radiator itself). Classic design Removable Front Covers only: Please note that if you wish to purchase a Classic removable front cover in order to provide valve access then, provided you have the external space available, you will need to add a further 75mm to the length of your radiator when ordering for each side of the radiator you wish to gain access to (i.e. 150mm if you wish to gain access to both sides). This will then ensure that you can reach the sides of the radiators through the internal sub-frame.
Height; this is from floor to the top of your actual radiator.
Depth; is measured from the wall to the front surface of your actual radiator - or the most forward measurement if your valves or other obstruction come out further than the radiator. Please note that you must ensure that the radiator depth entered when ordering is a minimum of 100mm if you wish to request a valve cut out otherwise the order will be cut automatically for a radiator depth of 100mm.
For made to measure covers, we then add the following EXTRA dimensions to allow for construction, fitting and airflow etc;

Do not add these measurements to your radiator size when ordering
The overall assembled external size of your made to measure cabinet can be determined by adding the following dimensions to the Length, Height & Depth measurements that you provide us with during the ordering process:
The overall assembled external length of the made to measure cabinet will be 56mm longer than the measurement you enter when ordering. This allows 10mm each end for air flow and 18mm each end for the thickness of the side panels. The top shelf will overhang the radiator cover by an additional 20mm at each end.
The overall assembled external height of the made to measure radiator cover will be 68mm taller than the measurement you enter. This allows 50mm for airflow above the radiator and 18mm for the thickness of the top shelf.
The overall assembled external depth of your made to measure radiator cover will be 52mm deeper than the measurement you enter (to the front of the side panels). This is made up of 10mm for airflow, 18mm for MDF thickness, 4mm for grille thickness and 20mm for the construction of the cabinet (as the front panel is recessed into the side panels). The top shelf will be a total of 62mm deeper than the measurement entered in this box (as there is a 10mm front shelf overhang). In the case of our classic design removable front covers, the necessary sub-frame adds a further 20mm to the overall depth of the cover.
If the above additons mean that the cabinet will not fit in the space you have available then please read our FAQ section for details on how to get around this or ensure that you email us before ordering.
