How to Measure Up a Thumb Guard for Kids

Measuring up for a fabric thumb guard for kids, to help them break the thumb sucking habit, is really simple.

Each Thumbsie® is handmade, so it’s important to measure carefully to ensure the best fit. Please use the diagram as a guide—if you’re unsure about sizing, feel free to contact us. When your thumb guard(s) arrive, try them on before washing. If the fit isn’t right—too tight, too loose, or simply uncomfortable—please don’t wear it and get in touch with us instead.

Get your child to choose from our fun selection of fabrics. We recommend buying three for each thumb they suck.

If you find that you need a bigger size then we do offer a bespoke service, making them suitable for teenagers too. All of our thumb guards are secured by Velcro around the wrist, are adjustable, and will, therefore fit all size wrists. If when your thumb guard(s) arrives it is not comfortable, too big or too tight please do not wear it.

The Thumbsie® will fit either the left or right hand. Your child is going to be wearing the fabric thumb guard during the day as well as night time, so we highly recommend buying three for each thumb that they suck, so you always have enough to maintain good hygiene. Our Thumb Sucking Book Bundles are a great discounted solution.
