What Level of Compression Socks Do I Need? Find Out
If you’ve ever wondered “what level of compression socks do I need?”, you’re not alone. With so many options and medical-sounding labels like “20–30 mmHg” or “graduated compression,” it’s easy to get confused. The truth is, choosing the right compression level depends on your needs, activity, and health condition. Whether you’re a frequent traveler, an athlete, or someone dealing with swelling, knowing the right compression level can make a big difference in comfort and circulation.
Let’s break it down simply so you can find out what level of compression socks is right for you.
What Are the Levels of Compression Socks?
Compression socks are measured in millimeters of mercury (mmHg), which indicates the amount of pressure they apply to your legs. The higher the number, the stronger the compression.
Here’s how the different levels of compression socks are categorized:
| Compression Level (mmHg) | Type | Ideal For |
|---|---|---|
| 8–15 mmHg | Mild | Everyday wear, light swelling, tired legs |
| 15–20 mmHg | Moderate | Travel, mild varicose veins, standing or sitting for long hours |
| 20–30 mmHg | Firm | Varicose veins, moderate swelling, post-surgery use |
| 30–40 mmHg | Extra Firm | Severe edema, lymphedema, chronic venous insufficiency (with doctor’s advice) |
| 40+ mmHg | Medical Grade | Prescribed for serious venous disorders only |
Graduated compression socks are tighter at the ankle and gradually loosen toward the calf. This helps blood flow back to the heart and reduces swelling and fatigue.
What Level of Compression Socks Do You Really Need?
Here’s a simple guide to match your situation to the right compression level.
| Your Situation or Lifestyle | Recommended Compression Level (mmHg) |
|---|---|
| Long-haul flights / frequent travel | 15–20 mmHg |
| Standing or sitting all day (e.g., teachers, nurses, office workers) | 15–20 mmHg |
| Mild swelling or tired legs after work | 8–15 mmHg |
| Moderate varicose veins or recovery after surgery | 20–30 mmHg |
| Chronic swelling, venous insufficiency, or lymphedema | 30–40 mmHg (doctor’s supervision) |
| Sports and post-workout recovery | 15–25 mmHg |
Start with moderate compression (15–20 mmHg) if you’re new to compression socks. You can always adjust as needed after observing how your legs feel.
How to Assess Your Level of Need
Choosing the right compression level isn’t about guesswork. Use this checklist to evaluate what you might need:
-
Check your daily activity:
Are you standing or sitting for hours at a time? Go for 15–20 mmHg. -
Look for symptoms:
-
Mild swelling, aching legs → 8–15 mmHg
-
Varicose veins, moderate swelling → 20–30 mmHg
-
-
Ask your doctor if you have:
-
Circulatory or venous conditions
-
Recent leg surgery or DVT risk
-
-
Measure your legs properly:
Compression socks should fit snugly, not painfully tight. Use a measuring tape around your ankle, calf, and sometimes thigh for the perfect fit.

Frequently Asked Questions
1. Can I start with a higher level just for comfort?
No. Higher compression doesn’t mean better comfort. In fact, starting with 20–30 mmHg without medical advice can cause discomfort or restrict circulation. Begin with 15–20 mmHg unless otherwise directed by a healthcare provider.
2. Does travel make me choose a higher level automatically?
Not necessarily. For flights longer than 4 hours, 15–20 mmHg compression socks are usually enough to reduce swelling and prevent blood clots (DVT). You don’t need stronger compression unless you have a medical condition.
3. How do I know if I am using the correct compression level I need?
You’re at the right level if your legs feel supported but not squeezed. If your socks leave deep marks or cause tingling, you may need a lighter level or a better fit.
