Graduated compression stockings squeeze hardest at the ankle and ease off steadily as they move up the leg. That pressure pattern helps move blood and fluid back toward the heart instead of letting it settle in the lower legs.
Picking the right pair comes down to pressure level and length. Fit matters just as much, because the wrong size can't deliver the gradient it was built for.
What This Guide Covers
- What makes a stocking "graduated," including why the pressure is strongest at the ankle and gradually decreases up the leg.
- Understand why graduated compression and anti-embolism stockings are for different situations, activity levels, and medical needs.
- Compare common compression ranges and learn why a higher number is not automatically better.
- Compare different lengths to find a fit that works.
- When you need medical guidance before you wear compression.
- Learn how to measure and why accurate sizing matters when your swelling changes throughout the day.
What Makes a Stocking "Graduated"
A graduated stocking is knit so the pressure peaks at the narrowest part of the ankle and drops gradually toward the knee or thigh. Leg veins push blood uphill against gravity, and that tapering squeeze helps. A stocking with even tightness from top to bottom offers no such push.
Here is how the pressure changes from one part of the leg to the next.
| Zone | Pressure | What It Does |
|---|---|---|
| Ankle | Highest | Starts moving blood and fluid upward where pooling is worst |
| Calf | Lower than the ankle | Keeps the upward flow going as the calf muscle contracts |
| Knee or thigh | Lowest | Lets blood continue past the top band instead of backing up below it |
Graduated Compression vs Anti-Embolism Stockings
Graduated compression stockings are made for people who are up and moving through the day. Anti-embolism stockings, often called TED hose, are meant for patients who are bedridden or recovering from surgery. The two look similar, but they are built for different situations.
The table below shows where each type is typically used.
| Type | Who It's For | Typical Setting |
|---|---|---|
| Graduated compression stockings | People who are walking and active, including those with chronic vein conditions | Daily wear at home and at work |
| Anti-embolism stockings (TED hose) | Patients who are immobile or recovering from surgery | Hospitals and post-surgical recovery at home |
| Light everyday support socks | People with tired or achy legs and no diagnosed condition | Long days of standing or sitting |
Choosing a Pressure Level
Compression is measured in millimeters of mercury (mmHg), and a higher number means firmer pressure. Most people can safely choose 15 to 20 mmHg on their own. Providers usually recommend firmer levels.
Use the chart below as a general starting point.
| Pressure Range | Support Level | Common Use |
|---|---|---|
| 8 to 15 mmHg | Light | Mildly achy legs after long periods of standing or sitting |
| 15 to 20 mmHg | Moderate | Day-to-day swelling and leg fatigue, plus pregnancy support |
| 20 to 30 mmHg | Firm | Varicose veins and mild edema, often recommended by a provider |
| 30 to 40 mmHg | Extra firm | Severe swelling or post-surgical recovery under medical guidance |
| 40 to 50 mmHg | Clinical | Advanced venous disease, prescribed and monitored by a provider |
If your provider has recommended compression after a DVT, see our medical compression socks for DVT.
Picking a Length
The right length depends on where your symptoms show up. Knee-highs are the easiest to put on and the most comfortable, which is a big reason people keep wearing them.
This table matches each length to the kind of need it covers best.
| Length | Coverage | Good Match For |
|---|---|---|
| Knee-high | Foot to about two finger-widths below the knee bend | Swelling in the feet and ankles, which covers most everyday needs |
| Thigh-high | Foot to the upper thigh | Veins or swelling that extend above the knee |
| Pantyhose or waist-high | Both legs up through the hips | Swelling high on both legs, or conditions like POTS where blood pools in the abdomen |

Who Should Check With a Doctor First
Compression isn't safe for everyone. Talk with a healthcare provider before wearing graduated stockings if any of these apply:
- Peripheral artery disease or other reduced blood flow to the legs
- Diabetes or neuropathy that dulls feeling in the feet
- A heart condition, especially one that causes fluid buildup
- Open wounds or fragile skin where the stocking would sit
- Sudden or painful swelling, especially in one leg
Sudden swelling in one leg with pain or warmth can signal a blood clot. Get medical care right away instead of reaching for compression.
Measuring for the Right Fit
Graduated compression only works when the stocking matches your leg. A few measurements taken at the right time of day make the difference.
- Measure in the morning, before swelling builds.
- Wrap a tape around the narrowest part of your ankle, just above the bone.
- Measure around the widest part of your calf.
- Measure from the floor to just below the bend of your knee.
- For thigh-highs, measure around the widest part of your thigh.
Remeasure after a big weight change or during pregnancy. A fuller calf usually calls for a wide calf style rather than a bigger size, since sizing up loosens the ankle where pressure matters most.
Putting Them On and Caring for Them
Put stockings on first thing in the morning, before you get out of bed and swelling starts. Roll the stocking down to the heel, slide your foot in, then unroll it up the leg. Rubber gloves or a donning aid can make this much easier.
These care habits keep the compression working as long as possible.
| Habit | Why It Matters |
|---|---|
| Wash after each wear | Washing removes skin oils and helps the fabric recover its shape |
| Follow the care label for drying | Carolon products can be machine dried per their care guidance, while many other brands call for air drying |
| Rotate two or more pairs | You always have a clean, fully rested pair ready |
| Replace every 3 to 6 months | Elastic fibers wear out, and older pairs lose their rated pressure |
