How to Measure up a Finger Guard for Kids

It’s really easy to measure up for a finger guard for kids – we even offer five different sizes.

Each Thumbsie® finger guard is hand made and designed to help stop finger sucking. It fits over two fingers either the middle and the index finger or the middle and the ring finger. Please ensure that you take care when measuring to get a good fit.

Please measure the length from the tip of the middle finger to the bend in the wrist, as shown in the diagram.

When ordering your fabric please select one of the following sizes:

Small 4 – 4.5 10.1 – 11.4
Medium 4.5 – 5 11.4 – 12.7

If you need the finger guard to be a little bigger then please order a bespoke finger guard.

All guards are secured by Velcro around the wrist which helps make the child feel more independent but also means that no matter the size of their wrist, they should feel comfortable as they can be adjusted.

When measuring for a Thumbsie® finger guard, please bear in mind that the product will fit either hand. We recommend your child wears the guard all the time, both day and night. For this reason, we suggest that you have three for each hand that they suck. We highly recommend our finger sucking bundles which will save money.
Thumbsies® can be hand washed or popped in the washing machine but you really want to make sure that you always have a clean one so that they have no excuses not to wear one.

A discount will be applied at the checkout page when you purchase more than one Thumbsie® so you don’t need to remember any coupon code.
