Size Guide
Units and product measurements
Measurements are presented in centimeters, with millimeter equivalents where precision is helpful. The individual product page is the final reference for the size and weight of a particular piece.
Product Measurements
Each product page includes the most important measurements to help you understand the scale, fit, and weight of the piece.
Rings
Ring measurements include the internal diameter, weight, and adjustable size range where applicable.
Cuffs and Bracelets
Measurements may include the internal diameter, opening width, overall dimensions, weight, and whether the piece can be adjusted.
Necklaces and Chains
The total chain length is provided, together with the adjustable length or extension range where available.
Earrings
Earring measurements include length, width, depth, and the weight of one earring. Earrings are sold as pairs unless the product page clearly states otherwise.
Adjustable rings
Find your size
Most NINO SEPO rings are one-size adjustable designs intended to fit an internal diameter of approximately 16–18.5 mm. Adjust the ring gently and never force it beyond the range stated on its product page.

How to measure a ring
- Choose a ring that already fits the intended finger.
- Place it on a flat surface and measure straight across the inside from edge to edge at the widest point. Do not include the metal.
- Compare that internal diameter with the range above and with the product page.
- If you are between measurements, choose the roomier fit. Fingers may change size with temperature, time of day, and activity, so measure more than once.
Finger sizes can differ between hands. Measure the exact finger and hand on which you plan to wear the ring. We do not currently offer resizing; request personalized sizing advice before ordering if you are unsure.
Cuffs and bracelets
Compare the product’s internal diameter and opening with the widest part of your wrist or hand that must pass through the piece. To put on a cuff, slide the opening over the narrow side of the wrist and rotate gently into position. If adjustment is necessary, use slow, even pressure once. Repeated opening and closing can weaken the metal or affect the finish.
Necklaces and chains
Total chain length is measured end to end, including the clasp. If an extension or multiple fastening points are included, the adjustable range is stated on the product page. To preview placement, measure a soft cord to the listed length and place it around the neck without pulling tight.
Earrings
Review the stated dimensions and the weight of one earring, especially for larger sculptural styles. Comfort varies by wearer and piercing. Earrings are sold as pairs unless the product page clearly states otherwise.
