Dia-Band size chart: find the right armband size
The right size keeps your Dia-Band armband in place all day without slipping or feeling tight. All sizes are based on the circumference of your upper arm, where the glucose sensor or patch pump is usually worn.
How to measure your arm
- Wrap a flexible tape measure or a piece of string around your upper arm, at the spot where the sensor or pod is placed. The device itself does not need to be included in the measurement.
- Keep the tape snug but not tight, then read the measurement in centimetres.
- Choose the size whose range includes your measurement in the tables below.

Fit tips
The armband should feel snug without being too tight: it stays securely in place and remains comfortable, without restricting circulation. If you have a question about sizing, see the Dia-Band FAQ or contact our team.
