SELECTING THE RIGHT SIZE DOOR KNOBS

Selecting the right size door knobs can be quite tricky. Here is a quick run down of the sizes we do and some tips to help you get door knob selection right first time!

Firstly remember that differences in size appear quite small eg 30mm, 38mm, 42mm, 50mm, however when seen on the diameter of the door knobs there is quite a large difference. You also need to consider the projection, ie how far the door knob sticks out from the door. Sizes are all indicated on each product. We give the door knob diameter, backplate diameter and height (projection) in mm.

If you are in doubt, the best thing to do is make paper templates of the diameter and stick this to your door. This will give you the best idea as to how they will look.

Another factor you may need to consider is how far back the door knobs can be set into your door. It is vital that you have enough space between the door frame and the edge of the door knob when closed

Cupboard Knobs

Sizes start at the lowest end at 20mm and we go up to 30mm, 32mm, 38mm, 40mm and 50mm options.

20mm, 30mm and 32mm make small cupboard door knobs and drawer pulls.

40mm diameter is also ideal as a cupboard knob or door pull perhaps on doors and drawers or where you want the knob to look more of a feature.

50mm diameter is for full size doors where only a pull is required (ie no requirement for turning door knobs). Remember these are the same size as a normal pair of door knobs.

Door Knobs and Centre Pulls

Our smallest door knob is the small cottage at 42mm, up to 100mm for our largest centre door pull.

50mm diameter  is the ideal size for most internal doors and the best selling size by far. This size suits normal size doors around size 1980 x 760mm. eg Richmond Beehive Door Knobs, Bloxwich Door Knobs, Medium Cottage Knobs

60 -75mm diameter these are the ones if you have large internal doors, or you just prefer the look of a larger door knob then

Over 75mm these are really only suitable as centre pulls. These are for large external doors, where the door knob is designed to be the central pull and big focal point on the door eg

    If you go to our website http://www.priorsrec.co.uk and click on brass door knobs we have several with 75mm rose. Look at Harley or Georgian Octagonal or Octagonal Pointed large. These designs are also made in polished nickel. Hope this helps.
