Wear your QRNT ring on your index, middle, or ring finger for the best signal. Non-dominant hand recommended to reduce wear and friction.

You can wear your QRNT ring on any finger of either hand &#x2014; but where you wear it affects the quality of your health data.For the most accurate readings, wear your ring on your index, middle, or ring finger.&#xA0;These fingers have larger blood vessels closer to the surface, which gives the PPG sensor a stronger, cleaner signal for heart rate, HRV, SpO2, and skin temperature measurements.Which hand?&#xA0;We recommend your non-dominant hand. It sees less friction, fewer impacts, and fewer scratches from daily tasks &#x2014; which means better sensor contact and a longer-lasting ring.A few things to keep in mind:<ul><li>The ring should sit comfortably snug with the sensor cluster on the palm side of your finger (the inside of your hand), not the top</li><li>Avoid wearing it on a finger that swells significantly during workouts &#x2014; this can temporarily affect fit and sensor contact</li><li>If you switch fingers, give the app a few nights to recalibrate to your new baseline</li></ul>

Which Finger Should I Wear My QRNT Ring On?

QRNT rings run smaller than standard sizes due to internal sensors. Most customers size up 1–2 sizes. Use the sizing kit before ordering.

Getting your size right is the most important step before your ring arrives. QRNT rings fit differently than standard jewelry rings &#x2014; read this before ordering.The right fit: snug, not tightYour QRNT ring should feel snug but comfortable. When you make a fist, there should be no gaps between the ring and your finger. The ring needs consistent contact with your skin for the sensors to work accurately &#x2014; a loose fit leads to noisy data.Size up from your normal ring sizeQRNT rings have raised internal sensors that take up space inside the band, which makes them fit tighter than a standard ring of the same size. Most customers need to size up at least one full size from their normal ring size, and sometimes two &#x2014; especially if your knuckle is wider than your base finger.Factors that affect your size:<ul><li>Knuckle width &#x2014; the ring needs to slide over it comfortably</li><li>Time of day &#x2014; fingers are slightly larger in the afternoon and evening</li><li>Temperature &#x2014; fingers swell slightly in heat and shrink in cold</li><li>Exercise &#x2014; fingers can swell noticeably during and after workouts</li></ul>Our recommendation: use the QRNT Sizing KitThe most reliable way to find your size is with the <a href="#">QRNT Sizing Kit</a>, which includes plastic sizers in every QRNT size. Wear your top two candidate sizes for at least 24 hours each &#x2014; including during sleep and a workout &#x2014; before deciding.<blockquote>Already ordered and the fit isn&apos;t right?

How to Choose the Right QALO QRNT Ring Size

QRNT's raised internal sensors reduce the effective inner diameter, so it fits tighter than a standard ring. Learn how to account for this.

Short answer: QRNT rings run smaller than standard ring sizes because the internal sensors create a tighter fit. When in doubt, size up.Why the difference?A standard ring is a simple band of uniform width. The QRNT ring has raised sensor nodes on the inner edge of the band &#x2014; the hardware that makes health tracking possible. These sensors reduce the effective inner diameter of the ring, which means a size 9 QRNT fits more like a size 8 standard ring.What to account for when sizing:<ul><li>Knuckle width &#x2014; your ring needs to fit over your knuckle without being too loose on your base finger once it&apos;s on</li><li>Swelling &#x2014; fingers naturally swell throughout the day, during exercise, and in hot weather. Size for your largest state, not your smallest</li><li>Snug is correct &#x2014; a ring that feels slightly snug when your hand is relaxed is likely the right size. It should never cause discomfort or restrict circulation</li></ul>How to check your current ring sizeIf you already know your standard ring size, start by trying one size up in the <a href="#">QRNT Sizing Kit</a>. Most customers find their fit 1&#x2013;2 sizes above their normal jewelry size.

Why QRNT Ring Sizes Are Different From Standard Ring Sizes

Order the QRNT Sizing Kit and wear your top size for 24 hours — including sleep and a workout — before finalizing your ring size.

The most accurate way to confirm your QRNT ring size is to use the QRNT Sizing Kit &#x2014; a set of plastic sizers in every available QRNT size that you can order before purchasing your ring.How to use the sizing kit:<ol><li>Order the <a href="#">QRNT Sizing Kit</a> from qalo.com</li><li>Start with the size that&apos;s 1&#x2013;2 sizes above your standard ring size</li><li>Wear your top candidate size for at least 24 hours, including during sleep and at least one workout</li><li>The correct size should feel snug when your hand is relaxed, slide over your knuckle with mild resistance, and never cause discomfort or leave a deep indentation when removed</li><li>If it slides off easily or spins freely, try the next size down</li></ol>Why 24 hours?Your finger changes size throughout the day and night. A ring that fits perfectly in the morning may feel tight after a workout or looser when you wake up. Wearing the sizer for a full day &#x2014; including sleep &#x2014; gives you a true picture of your fit across your body&apos;s natural fluctuations.<blockquote>Already have the ring and need a different size?
