Diameter Sets the Footprint
A bangle does not collapse to fit the box. Its fixed circular or near-circular shape decides the footprint before branding, finishes or opening style enter the discussion.
Custom Bangle Boxes should therefore start with the largest outside diameter of the jewellery in its normal resting shape. Measuring only the wrist opening can understate the space needed around thick metal, stones, enamel, hinges or raised decorative work. The box has to clear the full object, not just the space inside it.
This is the main difference from flexible bracelet packaging. A chain bracelet can follow a guided path. A bangle brings its own geometry into the case and needs the interior to respect that shape rather than pull it into another one.
