Measure up to replace existing handle fittings

In most instances we can make handles to fit existing fittings. To get this right we will need the measurements described below. All measurements are needed in millimetres (mm). Measurements required for numbers 2 & 3 must to be taken from and to the hole centres.

1. The size of the existing holes 
2. The distance between holes from centre to centre (only needed when the existing handle has 2 fittings e.g. rectangular handles)
3. The distance from the centre of the hole to the closest edge of the door.

Please supply actual written measurements, a photo showing a measuring tape or ruler to illustrate the measurement is unreliable with small dimensions.
