The plain-English compression guide
Compression looks complicated. It isn't. Five minutes with this page and you'll know exactly what level you need, how to measure, and how to get your garments on without a wrestling match.
1 · Pick your level
mmHg = millimeters of mercury, the same unit your blood pressure cuff uses. All medical compression is graduated: firmest at the ankle, easing up the leg, to push blood back toward the heart.
8–15 mmHg
Mild
Gentle everyday support. Best for tired, achy legs, minor swelling, long days on your feet, and prevention during travel. No prescription needed.
Tired legs · Prevention · Light travel support
15–20 mmHg
Moderate
The most popular over-the-counter level. Helps mild varicose veins, pregnancy swelling, and flight-related DVT risk. Still no prescription needed.
Mild varicose veins · Pregnancy · Frequent flyers
20–30 mmHg
Firm
Prescription territory — the most commonly prescribed level in the US. For moderate varicose veins, edema, post-surgical recovery, and DVT prevention after a clot. Frequently covered by insurance.
Diagnosed venous disease · Post-surgical · Often covered by insurance
30–40 mmHg
Extra Firm
For severe venous insufficiency, lymphedema management, and active leg ulcers. Should be worn under physician guidance — and is usually insurance-billable.
Lymphedema · Severe disease · Usually covered by insurance
Rule of thumb: if a doctor has named your condition (varicose veins, lymphedema, CVI), you'll likely land at 20–30 mmHg or above — and your garments will likely be insurance-eligible. Check your coverage →
2 · Measure correctly
Sizing is everything — a stocking that doesn't fit doesn't compress. Measure first thing in the morning, before your legs swell, with a soft tape measure against bare skin.
| Measurement point | Where | Needed for |
|---|---|---|
| Ankle | Narrowest point, just above the ankle bone | Every garment — the most important one |
| Calf | Widest part of your calf | Knee high and thigh high |
| Thigh | Widest part of your upper thigh | Thigh high and pantyhose |
| Length | Floor to just below knee crease (knee high) or to upper thigh (thigh high) | All styles |

3 · Get them on (the easy way)
- 1 Put on donning gloves — they add grip and protect the knit from nails and jewelry.
- 2 Turn the stocking inside-out down to the heel pocket (the "heel pocket" method).
- 3 Slip your foot in, position the heel exactly, then roll the fabric up your leg — never pull from the top band.
- 4 Smooth out wrinkles with gloved palms. Wrinkles = uneven pressure.
- 5 Wash after every wear (gentle cycle or hand wash) — clean knit restores elasticity and compression.
