PZ centres
Handle spindle to cylinder centre
Measure from the centre of the square spindle hole to the centre of the euro cylinder cut-out. Many uPVC handles are 92mm PZ, but always check yours.
uPVC handle measuring guide
Replacement uPVC and multipoint door handles need more than a rough visual match. Measure the PZ centres, fixing screw centres, backplate length, backplate width, and lever position before choosing a replacement.

Screw centres
Measure between the fixing screw centres. Replacement handles need these holes to line up with the existing door prep.
Backplate size
Measure the full backplate length and width so the new handle covers the old footprint on the door.
Lever offset
Check where the lever sits on the backplate. Handles can look similar but place the lever at different heights.
Not the handle?
If you are replacing the lock barrel rather than the handle set, use the euro cylinder measuring guide.
