When it comes to necklaces- especially chain or pearl necklaces- it's a matter of personal preference and style.
For most men's necklaces, the standard length is 20" | 51cm, which typically falls at the collarbone level.
To visualize this, you can imagine the chain resting between the top two buttons of a shirt, just below the collarbone.
However, necklace lengths do vary, ranging from 18" | 46cm to 30" | 76cm, offering a diverse selection to achieve the desired look.
Each size corresponds to a specific style, allowing you to choose the perfect length that compliments your outfit and personal preferences or style.
