Why the brand's sizing chart for compression garments is more important than your usual clothing size.
Understanding how compression works helps avoid unnecessary expenses and ensures proper support for the vessels.
Features of medical hosiery
Unlike regular clothing, which aims to fit comfortably against the body, compression products create strictly measured distributed pressure. This pressure is measured in mmHg and is distributed unevenly along the leg: maximum at the ankle (100%) and gradually decreasing towards the thigh (up to 30%).
If a product is chosen based on clothing size, the physiological pressure gradient is disrupted. Too loose hosiery does not provide the necessary effect, while tight hosiery can cause a tourniquet effect, leading to swelling and discomfort.
Main mistakes when choosing size
- •Relying on height and weight. These parameters only provide an approximate idea. Two people with the same height and weight may have different calf and thigh circumferences, which is critical for selecting stockings.
- •Using old measurements. The anatomical parameters of the legs can change. Measurements should be taken anew before each purchase.
- •Measuring in the afternoon. By evening, legs often swell, which will result in inflated measurements. As a result, the purchased product may be too loose in the morning when the leg has its natural volume.
- •Using universal size charts. Each brand has its own sizing grid. Size M from one manufacturer may correspond to size L from another.
How to take measurements correctly
To accurately select stockings, it is necessary to measure:
- 1. Ankle circumference (at the narrowest point above the ankle bone).
- 2. Calf circumference (at the widest part of the calf muscle).
- 3. Thigh circumference (5 cm below the groin or 25–30 cm above the knee).
- 4. Length of the leg from the heel to the groin.
The result of correctly selecting the size of compression hosiery.
A correctly selected product according to the brand's sizing grid:
- •fits snugly and evenly against the leg without forming wrinkles;
- •does not slip during movement and does not require constant readjustment;
- •does not cause numbness or painful sensations at the points where the elastic bands are fixed;
- •effectively supports the veins, reducing fatigue and swelling.
