RING SIZE GUIDE

HOW TO DETERMINE YOUR RING SIZE

Determine what your ring size is by measuring your finger or comparing one of your rings with our printable ring size chart: two practical and easy ways to find the perfect fit.

Regardless of the measuring method you choose, we recommend selecting a ring size that can be easily put on and taken off your finger. If your ideal fit falls between two sizes, we recommend choosing the larger one. Note that Bvlgari uses European sizes.

  • Measure your finger

    The size of your finger can vary depending on the time of day and temperature. For the most accurate result possible, we recommend you measure the size of your finger at the end of the day, and avoid taking any measurements on unusually hot or cold days.

  • Use a ring to find your size

    USE A RING TO FIND YOUR SIZE

    Take one of your rings that fits well on the finger you plan to wear your new Bvlgari ring on, considering that engagement rings and wedding bands are traditionally worn on the fourth finger of the left hand.
    Print the conversion chart page making sure the "Scale to fit" option is unchecked in the print dialogue box. Use a ruler to check that the ring conversion chart is scaled to 100%.
    Now place your ring over the circles below to determine which one matches your size. The inside of the ring should exactly match with the circle.

  • The perfect B.zero1 Ring Size

    Image of B.Zero1 rings with creative background.

    Due to the unique design of Bvlgari B.zero1 rings, their size differs from the standard ones for a ring. When purchasing a B.zero1 ring, you will most likely need to go up two sizes to ensure a proper fit.
    If using the Bvlgari Ring Sizer, we therefore recommend that you select a ring two sizes bigger than the size indicated on the Bvlgari Ring Sizer. Please be aware that all B.zero1 rings are not resizable.
    Refer to the Bvlgari B.zero1 Ring Size Chart below for further details.

    Bzero 1 Ring Height
    band mm inch
    1 band 4,8 0.16
    3 bands 9,3 0.35
    4 bands 11,9 0.43
    5 bands 13,8 0.51
