The Complete Guide to Graduated Compression Socks and Stockings
01
What are graduated compression socks and stockings, and how do they work?
Graduated compression socks and stockings are crafted using high-quality knitting machines and a variety of elastic yarns such as nylon, micro-nylon, cotton, and merino wool. These socks employ scientifically measured designs to create graduated compression, meaning the compression gradually decreases from the ankle to the thigh. This design aids in preventing the accumulation of blood in the legs.
02
Benefits and Uses of Graduated Compression Socks
Primarily utilized to enhance blood circulation in the legs, graduated compression socks are beneficial for addressing conditions like edema, varicose veins, and deep vein thrombosis (DVT). They are particularly advantageous for individuals who are bedridden for extended periods or recovering from surgery. Moreover, wearing compression socks can alleviate soreness and facilitate faster leg recovery post-activity.
Individuals who spend prolonged periods standing or sitting, as well as frequent travelers, can also reap the benefits of compression socks. By improving blood flow and reducing discomfort, compression socks contribute to overall leg health and comfort for a variety of lifestyles and situations.

Measurement Units of Compression Socks and Medical Stockings
Millimeter of mercury (mmHg)
A millimeter of mercury (mmHg) is a manometric unit of compression socks and stockings. According to German standards, compression socks usually have four compression levels:
Class I
18-21 mmHg
Class II
23-32 mmHg
Class III
34-46 mmHg
Class IV
Above 49 mmHg

Denier (Den)
Denier (Den) refers to the weight of yarn in grams per 9 kilometers. For example, if 9000 meters of yarn weighs 200 grams, it is labeled as 200 Den.
- A lighter Denier means thinner yarn, making socks soft and breathable.
- A heavier Denier indicates thicker yarn, providing better warmth.
FAQ
What's the difference between the German compression classes and mmHg ranges used elsewhere? +
German compression classes (I–IV) group mmHg ranges into standardized medical categories—Class I (18-21 mmHg) through Class IV (above 49 mmHg)—while some markets, like the US, use slightly different mmHg brackets for everyday versus medical-grade compression. Always check the specific mmHg value rather than relying on class labels alone.
Should I choose socks based on Denier or mmHg? +
They measure different things. mmHg is the actual compression applied to your leg, while Denier describes yarn thickness and affects warmth, breathability, and feel. Choose your mmHg based on your health needs, then pick a Denier that suits your climate and comfort preference.
Do I need a doctor's approval before wearing graduated compression stockings? +
For light, everyday compression, most healthy individuals don't need a prescription. However, it's recommended to choose medically certified progressive compression stockings based on your specific physical condition, and to consult your doctor for higher compression levels or existing venous conditions.
