When shopping for compression socks, you've likely encountered numbers like 15-20 mmHg. While these numbers might seem confusing at first, understanding what they mean is crucial for choosing the right compression level for your needs.

Understanding Compression Measurements

The measurement "mmHg" stands for millimeters of mercury, which is the standard unit used to measure pressure in medical settings. When you see compression sock measurements, the numbers indicate the amount of pressure applied to your legs, with the first number being the minimum pressure and the second being the maximum.

The Perfect Middle Ground

15-20 mmHg is considered mild to moderate compression and is the most commonly recommended level for everyday wear. Medical compression experts suggest this range because it provides sufficient support without being too restrictive. This level of compression is particularly beneficial for people who stand for long periods or experience mild swelling.

Benefits of 15-20 mmHg Compression

This moderate compression level is particularly effective for various situations. Pregnant women often prefer this range as it helps prevent swelling without being too tight. It's also ideal for travelers, office workers, and anyone looking to improve their circulation during daily activities.

When to Choose This Level

Understanding compression levels is essential for selecting the right socks. The 15-20 mmHg range is perfect for preventing fatigue, managing minor swelling, and providing comfort during pregnancy. Many maternity compression guides recommend this level for expectant mothers.

Style and Function

Today's compression socks aren't just about function - they can be stylish too. Many custom compression sock options allow you to enjoy the benefits of 15-20 mmHg compression while expressing your personal style through various colors and patterns.

Wrapping Up
