Measuring the Upper Arm

To get the most out of the flexible holders for the Libre and transmitters, it’s best to select the size that most closely fits your arm when it’s relaxed.

If you have a fabric measuring tape like your Mammy has in her sewing box, that would be ideal as it’s flexible. You can also use a metal measuring tape that you would have for DIY jobs around your house. If you don’t have either, use a strip of a newspaper sheet. 

For best results, ask someone to help.  Hold your naked upper arm (that doesn’t have any sensor on it) relaxed by your side. 

Upper Arm Measurement

Ask someone to wrap the the tape (or strip of newspaper) around your upper arm and line-up the start with the number that feels comfortable on your arm without being tight. Remember and take note of the number to the closest centimetre. For the newspaper, mark the spot that meets the end under it and then measure this afterwards with a ruler. 

Choose the closest size that’s a bit larger. The elasticated strap has a buckle and it can be moved to make it a bit tighter if needed. 

This method will ensure that the curvature of holder is matching the arm and snugly does the job of maintaining the tech in place.  The elasticated strap does not have to be too tight, resulting in the wearer having a far more comfortable experience – 24/7.
