Measurement Vector
When assessing your dimensions at home, prioritize cross-referencing both the inner diameter bounding box line and the total circumferential loop to optimize alignment accuracy.
Finding Your Size
Start With What Fits
Choose a ring you already wear comfortably on the intended finger — ideally one with a band width close to the Velorium piece you have in mind.
Measure Internal Boundaries
Lay it flat and measure straight across the inside, edge to edge, at its widest point. This is your inner diameter — the number we'll use.
Measure at the Right Moment
Hands change slightly through the day. Take your measurement in the evening, when your hands are at their most natural, and check that the size slides easily over your knuckle.
