How would you like to find your size?

Numeric size (e.g. 8) for US/Canada, EU, or Japan — or a letter size (e.g. P 1/2) for UK/Australia.

Classic Love (5.5mm) vs. Small Love (3.6mm) sizing

Crucial sizing differences between Cartier's iconic Love ring models.

Cartier Love rings use the European circumference scale (e.g., size 52 = 52 mm inner circumference = ~US size 6; size 54 = 54 mm inner circumference = ~US size 6.75–7).

Band Width Impact on Sizing:

  • Small Love Ring (3.6mm width): Fits true to your standard European ring size. If you normally wear EU 52 / US 6 in thin wedding bands, order size 52.
  • Classic Love Ring (5.5mm width): Covers significant surface area and offers zero elasticity. Cartier and luxury jewelers recommend ordering one size up (e.g., choose size 53 or 54 if you normally measure size 52) so it glides comfortably over the knuckle.

Lower-confidence data — Japan, India (VowJewels), India (The Vedic Crystals) comes from a single published retailer source, or is known to drift by 1–2 sizes at the top of the range. Confirm with the retailer before ordering.

Rounded scale — Germany / Netherlands uses a coarser step than US half-sizes, so one value can cover two neighbouring US sizes. Check the millimeter columns when you need to tell them apart.

Frequently asked questions

What is the sizing difference between Classic Love and Small Love rings?

The Classic Cartier Love ring has a band width of 5.5mm, whereas the Small Love ring is 3.6mm wide. The wider 5.5mm band covers more skin and feels tighter; Cartier recommends choosing one European size larger (e.g., size 53 instead of 52) for the Classic Love ring.

Can a Cartier Love ring be resized?

Because the iconic screw motifs and hallmarks are spaced symmetrically around the entire circumference of the gold band, traditional cutting-and-soldering resizing disrupts the design. Ensuring an accurate size prior to purchase is essential.

How does Cartier Love size 52 convert to US size?

Cartier size 52 corresponds to an inner circumference of 52 mm and inner diameter of 16.5 mm, which equals US size 6 (UK L½). Cartier size 54 corresponds to 54 mm circumference, which equals US size 6.75–7.
