Plastic ring sizer

Regular price
Sale price

Please: one ring sizer per order. This item is offered as a service to Knot & Splice customers and not to be purchased in large quantities or for corporate/wholesale use—thank you for understanding.

  • Ring size = determined by knuckle size. It is important to know that your ring size is determined by your knuckle size (the base of your finger will often be smaller, but the ring has to fit over the knuckle).
  • No need to size up for wide bands purchased through Knot & Splice: if our wider band ring listings state "fits size ___" we have already figured out the sizing for the wider band. No adjustments/sizing up are needed from you; the "fits size" already takes into account the width of the band.
  • Calibrated ring sizes (US standard): The ring sizers we offer in the shop are compatible with our calibrated mandrel (highest accuracy on the market) that we use in-studio to make/measure rings (made by Pepe Tools USA). We have found that, due to many jewelry professionals and pawn shops using un-calibrated mandrels and sizers, ring sizes may be off by 1/4–1/2 size if getting sized by someone else. Also, if sizing for a wider band, either request a wide band ring sizer (if getting sized at a jewelry/pawn shop), or add 1/4-1/2 size for your ring if you experience swelling or have wider base of your fingers (the soft part below your second knuckle where you wear your rings).
  • Partial refund incentive for getting the right size on your next Knot & Splice ring purchase: we will refund you $3 on your next order...just send an email to nicole [at] after your next ring order purchase and we will refund $3 to that order. Proof of purchase is required (your email should show a record of the ring sizer purchase on our end).
  • Ready to ship and will ship in a bubble mailer (US orders) or a flat envelope (international customers) for the most cost effective shipping rates.
  • If ordering this item with made-to-order jewelry, your order will ship when the entire order is ready to ship out to you (if you need this item sent separately, please place the order for your sizer by itself and then place your jewelry order—you will then receive two packages).
  • Shipping cost—Ring sizers shipping alone are usually $3-5 to ship worldwide. We will refund overages on shipping.
