Handle measurements often look similar on a product page, yet they describe different parts of the hardware. Confusing centre-to-centre spacing with overall length is one of the most common causes of incorrect orders. Learning three basic dimensions makes selection and installation much easier.
Centre-to-centre spacing
Centre-to-centre, often written as C-C, is the distance between the centres of the two fixing holes. This is the critical measurement when replacing an existing handle because the new handle must align with the drilled holes unless the shutter is repaired or redrilled.
Overall length
Overall length measures the handle from one outer end to the other. It determines how large the handle appears on the cabinet but does not tell you where the screw holes sit. Decorative end caps and overhangs can make the overall length considerably larger than the C-C measurement.
Projection and grip clearance
Projection is the distance the handle extends out from the shutter. Adequate projection provides finger clearance and a comfortable grip. Deep decorative handles can look impressive, but they should be checked near corners, adjacent shutters and walking paths.
Measure before ordering
Remove one existing handle and measure between the hole centres with a rigid ruler or calliper. Record shutter thickness and note whether the screw enters from the back. For a new project, use a template and confirm the final position with the designer or carpenter before drilling every door.
Frequently asked questions
Is a 160 mm handle 160 mm long?
Not necessarily. The figure may refer to C-C spacing; always check overall length separately.
Can I replace a handle with a different C-C size?
Only if you are prepared to fill old holes and drill new ones.
Does projection matter on drawers?
Yes. It affects grip comfort and clearance around neighbouring shutters and passages.
