Alessi Size Chart

Use this Alessi Size Chart to compare available measurements before choosing rings, overshirts, or other items where fit and dimensions matter. For the most accurate choice, always check the product page first.

Ring Size Chart

For rings, measure the inside diameter of a ring that already fits the intended finger. Measure across the widest inside area, from inner edge to inner edge.

How to Choose Your Size

  • Start with the size information shown on the product page, since available sizes can vary by item.
  • For rings, measure a ring that fits the same finger you plan to wear the new ring on.
  • For overshirts, compare your chest and sleeve measurements with the chart rather than relying only on your usual size.
  • Use the larger measurement as your guide if one body measurement falls into a different size range.

Measuring Tips

Measure carefully and keep the tape or ruler flat. For rings, measure the inside opening only, not the outer edge of the ring. For clothing, keep the measuring tape close to the body without pulling it too tight.

If possible, measure twice and compare the results. Small differences can affect comfort, especially for rings and fitted garments.

Fit Notes

Ring fit can feel different depending on finger shape, temperature, and the width of the ring. Overshirt fit may vary depending on whether you prefer a closer fit or extra room for layering.

If you are between sizes, choose based on how you prefer the item to feel. For rings, comfort and easy movement over the knuckle matter. For overshirts, consider whether you plan to wear lighter layers or thicker pieces underneath.
