Product Compression Levels

What is mmHg?

mmHg stands for millimeters of mercury and it is a measurement of pressure. In addition to being used on compression socks, it is also used for blood pressure readings. Common levels for compression socks include; 8-15mmHg, 15-20 mmHg, 20-30 mmHg and 30-40 mmHg. Compression socks provide graduated compression so mmHg is listed as a range. Below are general rules of thumb for compression range use:
  • 8-15 mmHg: Very light compression grading. Typically used for minor or occasional swelling
  • 15-20 mmHg: Most common OTC compression grading. Typically used for daily wear, travel and sports. 
  • 20-30 mmHg: Highest level of compression without a prescription. Typically used for daily wear, sports recovery, medical recovery and can help to manage mild symptoms of varicose and spider veins
  • 30-40 mmHg: This compression level requires a prescription. Typically used for serious conditions such as blood clots (DVT), severe swelling (edema), and severe varicose veins.
