Sizing
Three methods. One certainty. VOWCRAFT bands are comfort-fit — if you're between sizes, size up half.
Sizing Methods
Use whichever fits your situation. All three are equally accurate when done carefully.
Place an existing ring over the circles below to find your inner diameter. Works on any screen — calibrate first.
Place an existing ring flat over the circle that matches its inner edge
Sizes shown are US. Diameters: size 5 = 15.7mm, size 6 = 16.5mm, size 7 = 17.3mm, size 8 = 18.2mm, size 9 = 19.0mm, size 10 = 19.8mm, size 11 = 20.6mm, size 12 = 21.4mm, size 13 = 22.2mm.
No existing ring? Wrap a thin strip of paper or string around your finger, mark where it meets, measure the length.
Tip: Measure in the evening — fingers expand slightly throughout the day. Repeat 3× and use the average.
Already own a ring that fits perfectly? Measure its inner diameter with a ruler or calipers.
Comfort-fit bands like VOWCRAFT's sit slightly looser on the finger than a standard flat-fit ring of the same diameter. If your reference ring is flat-fit, order the same size. If it's also comfort-fit, measure accurately.

All VOWCRAFT rings are comfort-fit. If you're between sizes, order the larger half-size. Highlighted rows are the most common sizes for men's wedding bands.
Per-Form Guidance
Each VOWCRAFT form has a distinct profile. Width and cross-section affect how a ring feels on the finger — here's what to know before you order.
The domed outer profile sits proud of the finger, which can feel wider than it measures. The inner comfort-fit curve removes friction — but the 6mm width means fingers feel the presence.
The flat profile and narrower 4mm width make Planus our most forgiving fit. The straight inner wall feels different from a comfort-fit band — it's precise, not clingy.
Classic court profile, rounded inside and out. The most universally comfortable form — the interior curve rolls over the knuckle and settles naturally. Mid-width at 5mm suits most fingers.
