Sizing Guide

How it works

1. Order your ring

Place the order by selecting the “Free Sizing Kit” option. We will send you a sizing kit before your Leep Ring ships.

2. Test your size

When the sizing kit arrives, test the sizes on your preferred finger. For best performance and accuracy we recommend the index, middle or ring finger. Once you have chosen a size, wear it for at least 24 hours, including when you sleep.

3. Confirm your size

Once you are sure your test ring is comfortable, click through to your order details from your order confirmation email and select “Change product options” to choose your perfect size.

How to choose your perfect size

Step 1

Choose your finger

The Leep Ring can be worn on either hand. For optimal accuracy, we recommend wearing it on your index finger, middle or ring finger.

Step 2

Ensure a secure fit

When wearing the ring, ensure the sensors are facing palm side up (under the engraved “L”) and does not rotate easily. Ensure the ring sits comfortably but securely. Try one size up and down to be sure.

Step 3

Wear for 24 hours

Once you’ve chosen your perfect size, try wearing it for 24 hours (including when you sleep). Your fingers will naturally expand and contract throughout the day due to temperature and activity, and a good fit should stay securely and comfortably in place without any rotation.

FAQ

What if I am in between two sizes?

Choose the larger size. A slightly looser ring will be more comfortable for 24/7 wear while still maintaining accurate sensor contact. Your ring should slide on with gentle resistance but not feel tight or leave marks. Finger size naturally fluctuates throughout the day, so the larger size accommodates these changes better.

Can I borrow someone else's Sizing Kit?

We don't recommend sharing Sizing Kits for hygiene reasons and accurate sizing. Ring fit is highly personal - even similar finger sizes may require different ring sizes based on individual comfort preferences and how your fingers respond to temperature and activity. Each Leep Ring purchase includes a complimentary Sizing Kit.

Can I wear the ring on any finger?

We recommend wearing your Leep Ring on your index, middle, or ring finger for optimal accuracy. These fingers provide the most consistent sensor readings due to better blood flow and stability during movement and sleep. Avoid wearing on your thumb or pinky, as these positions can compromise data quality. Choose the finger that feels most comfortable for 24/7 wear.

What if my fingers expand and shrink during the day?

This is completely normal! Fingers naturally fluctuate in size due to temperature, hydration, exercise, and time of day. That's why we recommend wearing the Sizing Kit for 24-48 hours - to test fit during these natural changes. Choose a size that feels comfortable at your finger's largest (typically evenings or after workouts) while still staying secure at its smallest (usually mornings).

How do I submit my size after trying the Sizing Kit?

Once you've determined your perfect fit, simply click through to your order details from your order confirmation email and select “Change product options” to choose your size. We'll then manufacture and ship your personalized Leep Ring. Make sure to submit within 30 days of receiving your Sizing Kit to avoid delays.
