What are Compression Levels?

The manufacturers of medical and support hosiery follow different standards usually UK or EU (Europe), we here at Daylong have made our own range of compressions to make this easier, the chart below shows where the different standards fit in with our own chart. Remember it's up to your doctor to decide which level of compression is right for you.

Who uses the Different Standards?

The EU or European standard is typically used by companies like Venosan and some Activa products
The UK standard is used by all products available on prescription such as products from Credalast and the British drug tariff range from Activa.

What is mmHg?




  1. Graduated compression hosiery, is hosiery that has a particular compression at the ankle which is measured by mmHg or millimetres of mercury at the ankle (Represented by the yellow arrow on the diagram).
  2. This compression is then graduated away from the ankle and gets gradually less towards the top of the hosiery and towards the toes (Represented by the Red waves which get thinner towards the top of the image).
  3. The image right illustrates this, the orange arrows represent the compression at the ankle and the blur gradient represents the compression getting less towards the top of the leg and towards the toes.
