How To Measure A Door To Fit Door Handles


When choosing new door handles it is constantly advised to measure your door to guarantee that the deals with will fit completely.

How to Measure Internal Door Handles

There a few different measurements that it will certainly work for you to know when it concerns how to measure interior door deals with;

Door Thickness 

Measure the door from the within to the exterior. Lots of interior doors are generally made to 35mm Thickness. A conventional FD30 Fire Door is normally 44mm Thickness. Exterior doors will certainly also typically measure 44mm, and much more modern-day UPVC doors and shielded doors will usually be much thicker.

There are also always custom-sized doors that do not fit the standards - Don't fret if you have a different measurement we can constantly provide the appropriate sized fixings to attach the handles from both sides of the door.

Door Height 

Measure the door from all-time low to the top of the door.

The common height of a door is typically either 1981mm (78"), or occasionally 2032mm (80") or 2040mm. Once again there are constantly custom-sized doors, especially in older properties.

This measurement is particularly helpful if you are preparing to get new door hinges to calculate the load-bearing requirement of the hinges.

Stile Width

Door Knobs will certainly usually be suited the midrail area of the door where the door stile is also slim.


Measure from the edge of the door to the centre of the door knob or take care of.

The sector requirements are generally either 44mm/ 57mm/ 82mm/ 107mm/ 130mm. Preferably you will certainly try and select the backset measurement that sites the door handle in the middle of the door stile.

We recommend that a shorter backset is selected when a door is polished to avoid the lock mechanism satisfying the discount of the glass.

When fitting a door knob it is important that a longer backset measurement is selected as if the door knob is fitted as well close to the edge of the door after that you will not be able to operate the door knob without scratching your knuckles on the door structure.

Centre to Centre 

Measure from the centre of the spindle hole to the centre of the lock hole. The market standards for UK locks vary on the type of lock being utilized;
