Firm Graduated Compression
Designed to apply stronger pressure at the ankle and gradually decrease upward.
20 to 30 mmHg is firm compression. It provides more support than moderate 15 to 20 mmHg socks, making it a common choice for women with more noticeable swelling or visible varicose veins.
Women's compression stockings also need to fit real leg shapes. Standard compression often assumes narrow calves, predictable proportions, and minimal swelling. That can cause rolling, digging, or a tight top band.

This compression level is often the right fit when mild support no longer feels like enough. Women may choose 20 to 30 mmHg for long shifts, travel, visible vein symptoms, or swelling that returns throughout the day.

Compression socks and stockings are measured in mmHg, or millimeters of mercury. The higher the number, the firmer the compression. Graduated compression means pressure is strongest at the ankle and gradually decreases upward.
| Compression Level | Support Level | Typical Use |
|---|---|---|
| 8 to 15 mmHg | Light |
Mild fatigue, short travel, light daily support. |
| 15 to 20 mmHg | Moderate |
Mild swelling, standing jobs, general support. |
| 20 to 30 mmHg | Firm |
Varicose veins, stronger swelling support, more noticeable leg fatigue. |
| 30 to 40 mmHg | Extra Firm |
More advanced support needs, usually used with provider guidance. |
Fit matters with firm compression. A stocking that is too small may dig in or feel painful. A stocking that is too large will not deliver the intended support.
This calculator is a general guide only. Always review the size chart on the product page before ordering.
| Measurement | Where to Measure | Why It Matters |
|---|---|---|
| Ankle | Narrowest point above the ankle bone. |
Determines the strongest compression zone. |
| Calf | Widest part of the calf. |
Helps prevent rolling, digging, or a poor fit. |
| Length | Floor to below knee or thigh measurement point. |
Helps the stocking sit in the correct place. |
| Thigh | Widest thigh point for thigh-high styles. |
Required for thigh-high fit. |

Here are answers to common questions about firm compression stockings for women.
Not for everyone. Many women wear 20 to 30 mmHg during the day for stronger swelling or varicose vein support. If you are new to compression or have health conditions, ask a healthcare provider before starting.
Choose knee-high if your symptoms stay below the knee. Choose thigh-high if swelling, varicose veins, or provider recommendations involve the upper leg.
Choose open toe if you want more forefoot room or a cooler feel. Choose closed toe if you prefer a traditional sock or stocking feel inside everyday shoes.
Some women use 20 to 30 mmHg during pregnancy, but pregnancy changes circulation and swelling patterns. Ask your healthcare provider which level is appropriate.
20 to 30 mmHg is often available without a prescription, but you should consult your healthcare provider if you have diabetes, neuropathy, peripheral artery disease, heart conditions, or circulation problems.
