Knee-high and thigh-high stockings use different garment lengths and measurement charts. Compare the exact maker's fit instructions; if compression is for medical use, have a healthcare professional select the product and pressure.
Knee-high and thigh-high compression garments differ in how far the product extends and which measurements its size chart uses. Length alone does not determine which garment is appropriate for an individual medical need.
| Fit detail | Knee-high or calf-length | Thigh-length |
|---|---|---|
| Garment endpoint | Below the knee, according to the manufacturer’s fitting directions | At the upper thigh, according to the manufacturer’s fitting directions |
| Measurements to check | Ankle and calf circumferences plus the maker’s length point | Ankle, calf and thigh circumferences plus the maker’s length points |
| Source example | Medi says its knee or calf length stocking should sit below the hollow of the knee | Medi says its thigh stocking should sit below the fold of the buttocks |
| Selection | Use the product chart and clinician or fitter instructions for medical use | Use the product chart and clinician or fitter instructions for medical use |
MedlinePlus describes stocking lengths from knee-high to the top of the thigh and advises patients to ask their provider what kind is right for them. Medi provides separate application guidance by garment length and says measurements should be taken regularly by a fitter in its sizing guidance.
Do not choose a medical compression level or length from a general buying guide. Follow a healthcare professional’s direction and the exact product instructions.
