Perfect Fit Starts Here — Find Your Ideal Oura Ring Size Before Committing

Ensure that your smart ring fits comfortably and delivers the most accurate biometric insights possible with this dedicated sizing kit for the Oura Ring 4. Designed specifically for the Oura Ring’s unique measurement system, this kit takes the guesswork out of online ring sizing — making your final purchase easier and more confident than ever.

Unlike traditional jewelry, the Oura Ring 4 uses proprietary sizing that doesn’t align perfectly with standard US ring sizes. A correct fit is essential because a snug, well-fitting ring ensures optimal sensor contact with your skin — critical for precise health tracking including sleep, heart rate, temperature, and activity trends.

This sizing kit lets you try multiple ring sizes at home to determine your best match before buying the actual smart ring, so you don’t end up with an uncomfortable or loose fit once the real ring arrives.

What’s Included

  • A set of durable plastic ring sizers covering the full range of Oura Ring 4 sizes (typically Sizes 4–15).
  • Easy-to-use sizing guides — simply try different sizers on your finger to see what feels best.
  • Excellent for testing different fingers like index, middle, or ring finger before making your final decision.

Tip: Wear your chosen sizer for a few hours or even a full day — finger size naturally fluctuates throughout the day. The best fit should feel snug but never too tight or restrictive.

Features

  • Accurate Fit: Designed specifically for the Oura Ring 4’s unique sizing system.
  • Comfort First: Helps you find a size that feels great for all-day wear.
  • Easy to Use: Perfect for home sizing — no need to visit a jeweler.

How To Use

1. Order the sizing kit and receive it at home.
2. Try different sizes by slipping on the plastic sizers.
3. Identify your ideal ring fit — snug, secure, and comfortable.

    We want you to be happy with the purchase you have made from us. If you are not completely satisfied, you may return the product to us and we will either refund, credit, repair/replace it, subject to the below terms and conditions. 

    You can return purchases for a refund (excl shipping). Please notify us within 7 days and ensure item is ready maximum 10 days after delivery date.

    Please ensure to log your return request within 7 days of receipt of your item. Please ensure to select the correct reason for return:

    - Changed my mind / Item exchange

    - Faulty on arrival

    - Incorrect item received

    All items are covered by a 12 month warranty (unless otherwise stated) which will be honoured directly by GeeWiz. All products will either be replaced/repaired/refunded depending on stock availability. Products will require evaluation by GeeWiz before a warranty claim can be accepted.

    Should the item being returned for assessment be found to be in good working order, unfortunately, there will be a collection fee that will apply.

    The collection fees are as follows:

    - For returns on items that were sent with free shipping: R198

    - For returns that had a surcharge, the same surcharge will apply for collection.

    Please log your return on your account, under the returns manager.

    We do not reimburse your fee to ship to us, but we will pay for return shipping if the item is subject to replacement. If the item you wish to return was ordered incorrectly / is no longer required / you have changed your mind, there is a collection fee that will be charged (please refer to the above) and this will be deducted from the refund amount once the supplier has credited us. Please note GeeWiz will only cover return shipping of a faulty unit within 6 months of purchase, after which, a shipping fee (starting from R198) will be applicable to you for the return of the unit.

    Any disputes relating to ordered items being short/incorrectly shipped will only be entertained if reported to GeeWiz within 3 days of delivery/collection.

    Refunds are subject to inspection of item(s) - in some cases, items will need to be sent to supplier for evaluation and testing. This can take up to 15 working days. Once a refund has been approved, this may take 3 - 5 business days to be processed.

    ALL returns are subject to up to a 30% restocking fee if item is no longer in BRAND NEW condition or if item seal/packaging has been broken.

    Please re-package safely and include all original product packaging.  

    All software products are unfortunately not eligible for credit or refund once purchased.

    After the 6-month period, you will no longer be eligible and won't be able to receive a refund. We can however replace or repair depending on the outcome after our team of professionals has inspected the product.

    Should a warranty sticker not be present on an item, the warranty is immediately null and void.

    Batteries are covered under warranty, but please note that GEL, AGM and LEAD ACID have limited cycle runs. These are typically around 200 cycles and may run out before the end of the warranty. Once the cycles have been depleted, it means the battery has reached the end of life and will no longer be a warranty claim.

    GeeWiz reserves the right to refuse a refund if the item is damaged from misuse, items are missing, or if the product is altered in any way. 

    GeeWiz or its affiliates are not responsible for damage or loss of any kind that may occur as a result of using or misusing any product purchased from us.
