Plus size compression socks: our exact size range
We size every sock by calf circumference at the widest point. Here is the full range:
| Size | Calf (inches) | Fit |
|---|---|---|
| M | 8 to 11 | Slim |
| L | 11 to 13 | Standard |
| XL | 13 to 16 | Standard |
| 2XL | 16 to 18 | Wide |
| 3XL | 18 to 20 | Extra wide |
If you are between sizes, choose the larger one. 2XL is the same as XXL, and 3XL is the same as XXXL.
We want to be straight with you: 20 inches is our limit. Above that, a ready-made sock from us would be too tight at the calf to be comfortable or safe, and we would rather tell you now than sell you a pair that does not work.
How to measure large calves for compression socks
- Measure in the morning. MedlinePlus notes your legs are least swollen early in the day. A measurement taken in the evening can push you into a size that is too loose by the next morning.
- Sit down with your foot flat on the floor and your knee at a right angle.
- Find the widest part of your calf. Slide a soft tape measure up and down until you find the largest number.
- Keep the tape snug, flat against the skin, without pressing in.
- Measure both legs. Many people have one calf a little larger. Use the bigger number.
Our compression sock size guide has the chart in both inches and centimeters.
Why a zipper helps on a wide calf
A regular compression sock is a narrow tube that has to stretch open over your heel, then get dragged up past the widest part of your calf. The bigger your calf, the more the fabric has to stretch, and the harder you have to pull. For a lot of people with larger legs, that is where compression socks stop being an option.
A full-length side zipper takes most of that effort away. You open the sock flat, set your heel, and close it around your leg. The fabric never has to pass over the widest point. A soft fabric guard sits behind the teeth, so the zipper does not press into your skin.
If bending forward is hard, sit in a sturdy chair and rest your foot on a low stool or step while you zip. Our guide on how to put on compression socks has more tips.
Compression socks for large legs: what a good fit feels like
A good fit feels like a firm, even hug that is strongest at the ankle and eases toward the knee.
- Top band: MedlinePlus says knee-length stockings should reach about two finger-widths below the bend of the knee.
- No bunching: smooth out any folds. Wrinkles create pressure lines.
- No digging: a deep groove at the top band, pain, tingling, numbness or toes changing color mean the sock is too tight or not right for you. Take it off.
If you measure right at 20 inches, 3XL will feel firm. That is expected, but it should not hurt.
Both styles come in 2XL and 3XL. Open-toe zipper compression socks can be easier if you have wide feet or prefer sandals. If the size is not right once you try them, our 90-day money-back guarantee covers pairs you have worn and washed.
XXL and 3XL compression socks: style, color and reordering
Our 2XL and 3XL socks are the same product as every other size, with the same 15-20 mmHg graduated compression, fabric and zipper. Only the calf width changes.
- Color. Black looks like a plain dark sock with trousers, jeans and boots. Beige is the quieter choice under skirts and light trousers.
- Zipper side. Most people find the outer side of the leg easiest to reach. Turn it to the inner side if you would rather keep it out of sight.
- Measure again before you reorder. If your weight has changed or your legs swell more than they used to, take a fresh morning measurement. Your size can change, and a sock that fit last year may now be too loose or too tight.
Extra wide calf over 20 inches? When made-to-measure is better
Ready-made socks, ours included, are built around standard leg shapes. Made-to-measure stockings are a better route if:
- Your calf is wider than 20 inches
- Your ankle and calf are very different in size from what standard charts expect
- Your legs are very different from each other in size or shape
- Your doctor wants a specific compression level
Cleveland Clinic notes that for prescription compression, trained staff measure you to make sure of a good fit and show you how to put the stockings on. Ask your doctor or a medical supply store with a certified fitter. Cleveland Clinic also notes stockings rated 20 mmHg or higher need a prescription.
If your legs have recently grown larger because of swelling, see a doctor before buying any sock. New or worse swelling in one leg, or a leg that is red or warm, needs prompt medical attention. Compression is not suitable if you have problems with blood flow in your arteries.
