Measurement of graduated compression socks are done in mmHg (millimeters of mercury), and there are five different levels of compression.

A lower number signifies less compression; on the other hand, higher numbers indicate increased compression.

To break it down, check this below:

Compression Level: 8-15mmHg (Mild Compression)

  • This is the least level of compression
  • It may relieve or reduce the soreness in aching and tired legs.
  • It could be useful for minimizing swelling legs, feet, and ankles.
  • It could be efficient for short trips, mild relief, desk, or stationary workers.

Compression Level: 15-20mmHg (Moderate Compression)

  • Offers a mild level of compression
  • One of the most common compression levels used
  • It might be recommended for those who need relief from swollen ankles and legs during pregnancy.
  • It is potentially vital for minimizing the risk of DVT (Deep Vein Thrombosis)
  • It could offer relief and limit the pain that comes from spider and varicose veins.
  • It’s recommended for folks who sit or stand for an extended period, offering smooth blood circulation in the legs.

Compression Level: 20-30mmHg (Firm Compression)

  • Offers a firm level of compression
  • One of the most common compression levels used.
  • It can relieve from moderate to severe spider and varicose vein
  • It is usually prescribed for folks with abnormal swelling and edema

Compression Level: 40-50mmHg (Extreme Compression)

  • The highest level of compression
  • Recommended by a doctor to patients with severe venous insufficiencies

Now that you’ve identified the varying levels of compression and the prescriptions, what’s next is determining the size of compression socks that you should purchase.

What Compression Sock Sizes Should You Purchase?

In order to determine this, you would need two essential things:

Measure your leg: On measuring your leg, there are several questions, this include:

  • Who should measure?
  • How should it be measured?
  • What time should it be done?

Identifying where the exact pain point is: Identifying the pain point would be useful in deciding if you should only get a tight, sleeve, or stocking. It is essential to note that compression gear can vary when it comes to sizes across brands. Therefore accurate measurement is an incredible step in selecting the best size when you decide to get one for yourself.

Simple measurement of size, weight, and height might determine the dimensions of light compression stockings; most compression socks demand the measurement of the circumference of the leg at a needed point.

It is often required to make use of a tape to carry out the measurements. A string and a ruler would be a handy tool too. The string will be used to take measures while the ruler will be used to verify the lengths in centimeters. So now let’s get to the steps:

Step 1: At each circumferential point, the thigh, ankle, or calf, mark the leg with a non-toxic, non-permanent marker.

Step 2: Measure the length of the leg right from the ground to the marked circumference point and take out the measurement and write it down.

Step 3: Search for the narrowest point of the ankle, then measure the circumference and note it down as “Ankle Measurement.”

Step 4: Find the largest part of your calf and measure. Write it down as “calf measurement.” You might need to measure the base, middle, and the peak part of your calf to determine the largest part of your calf.

Step 5: Pull off your sandals or shoes and measure the whole length of the leg from the ground to the area below the bend of your knee. You must measure the length of your leg correctly since compression socks can be ineffective or uncomfortable when they are excessively long or excessively short. Write down the measurement of the length and dub it “length measurement.” If you require knee-high compression stockings, you would not require any measures at all

Step 6: If you need thigh-high compression gear, you will require accurate measurements of your thigh length and circumference of the whole leg. Stick with the procedure analyzed from step one to step four. When you are done with step four, measure your thigh circumference by selecting the widest part of your thigh, often, it is the areas right below your buttocks and measures the circumference. Pen down the length and label it “thigh circumference.”

Step 7: Accurately measure the length of your leg right from the ground to the top of your thigh. Write down this measurement. Then compare these measurements with any appropriate sizing chart that you find to determine the size of compression that you need.

Of course, it must be noted that sizes may differ due to differences in brands of compression stockings available. But do keep in mind that individual manufacturers of compression stockings have their compression socks sizing chart. For instance, a medium-size in a brand might not be the same in another firm. Some brands offer petite lengths, while some do not. That is why identifying your measurement is undoubtedly a vital step to get the right compression sock size.

Now let’s analyze the typical compression stockings size chart

Whenever you are choosing from the compression sock sizes, essentially measure the circumference of your calf and circumference of your ankle. Well, what if your measurement falls in between sizes, what should be done?

Try smaller sizes closer to you; don’t opt-in for sizes higher than you. Undoubtedly, the comfort and benefits of a compression sock will be improved if you are on the correct size or something near it.

Incredibly, you can efficiently do better by enhancing certain aspects of your life. These aspects include things like exercise, getting proper clothing, posture, and wearing the right level of compression socks.

Additionally, since compression is usually firm around the ankle and reduces up the leg, it would be essential to seek the size that fits the circumference of your ankle if you are in between two sizes. Often, the foot of the stockings might be too small or large, but you will be able to identify this immediately you are wearing the stocking; nevertheless, if the foot size is three times lower, not larger than your standard size, opt-in for socks with an open toe. But who should measure, and when should it be done?

It is often advisable that you let trained medical personnel measure for you. Regardless, it might be a necessity to personally determine your size yourself if you will be purchasing it online, or you just desire to make adjustments to the one you currently have after undergoing a weight loss management or you gained weight recently.

Also, regarding when measurement should be taken, it must be noted that measure must be done early in the morning, at that time; the leg is at its smallest size.
