Plus size compression leggings: sizing, fit and what to look for

If you have been searching for plus size compression leggings and bouncing between fashion tights and made-to-measure medical garments, you are not alone. The question is usually practical: will this pair actually come in my size, and will it feel firm enough to wear all day?

This guide answers that using Supacore's published size charts and the sizes we actually offer on our product pages. It is written for shoppers in Australia, the USA, Canada and the UK. We use both lipedema and lipoedema, which are the same condition spelled differently. It is general information, not medical advice, so please talk to your doctor or therapist about your own plan.

The short answer

Many women's CORETECH® compression leggings, including our lipedema compression leggings and POTS compression leggings, are offered from XS through to XXXL. They are sized by height and weight, not by dress size or your usual clothing size. If you are between sizes, choose the smaller size. We also offer free size exchanges.

What "plus size" means on these leggings

Supacore does not label a separate plus size collection. The range is in the size run itself. On the official women's CORETECH® leggings size guide (the chart published on our sizing guides page in September 2025), sizes go from XS to XXXL:

• XXXL covers the top of the chart, around 110 to 125 kg (about 243 to 276 lb), for heights from about 160 cm (5 ft 3 in) up to 190 cm (6 ft 3 in).
• XXL sits just below that, around 95 to 110 kg (about 209 to 243 lb), again depending on height.
• XL, L, M, S and XS fill the rest of the chart down to about 35 kg.

Always use the live chart, because the right size depends on both measurements, not weight alone. A taller person and a shorter person at the same weight can fall into different sizes.

Some other styles are narrower. For example, the published women's CORETECH® shorts chart and the Jenny pregnancy leggings chart currently go to XXL (around 95 to 110 kg). Some shorts, including certain Mary and Nova styles, also list an XXXL option on the product page. Check the size list and chart for the exact garment you are buying.

Why you should not use your usual clothing size

Medical-grade compression is meant to feel firmer than everyday tights. Our sizing guides say clearly that regular clothing sizes do not match CORETECH® sizing. Plot your height and weight on the chart, then choose that size, even if the letter is smaller than the size you buy in jeans or gym leggings.

If you are on the line between two sizes, choose the smaller size. The garment should be a neat, tight fit, but it should not inhibit circulation, cause numbness or make pain worse. If it does, take it off and get in touch so we can help with a size exchange.

What to look for in plus size compression leggings

1. A size run that actually includes you

A product is only a plus size option if the size you need is listed and plotted on a real chart. Look for women's CORETECH®, POTS and lipedema leggings that go to XXXL, and confirm your height and weight sit inside that band.

2. Coverage where you need support

For lipedema, that usually means the hips, thighs and lower legs, and sometimes the abdomen, so waist-to-ankle leggings are a better starting point than knee-high socks. For POTS, waist-high styles that also cover the abdomen are the ones many people look for. Shop the full women's compression leggings range if you are comparing lengths and waist heights.

3. Graduated, medical-grade compression

The main CORETECH®, POTS and lipedema leggings deliver graduated compression of 25+ mmHg, as stated on the product page. Emma and Jenny pregnancy styles are 15-20 mmHg and are a different, lighter option. There is no single "right" level for every person, so take advice from your clinician if you have been prescribed a class of garment.

4. A fit you can put on and wear

Firm compression can be a struggle to pull on, especially on tender or swollen legs. A seamless, circular-knit legging is often easier for everyday wear than a stiff, custom flat-knit garment. Some people use an everyday pair between clinic fittings, or on days when a made-to-measure garment is being replaced. Your therapist can tell you what belongs in your own routine.

Which Supacore leggings go to XXXL?

These women's styles are offered from XS (or S) to XXXL, or to 3XL where that label is used on the product:

• Lipedema medical-grade compression leggings
• POTS compression leggings (black) and the other POTS colourways in the women's POTS collection, including Meryl extra high waisted POTS leggings
• Amelia postpartum compression leggings and other CORETECH® recovery leggings in the postpartum compression range

Some men's CORETECH® leggings, including the David leggings and Carl POTS leggings, also list sizes through XXXL. Use the men's size guide and the men's compression tights and leggings collection to choose those.

Everyday wear, lipedema and POTS

Compression does not remove lipedema fat, and it is not a cure for POTS. What many people want is a pair they can wear to work, to the shops or on a flight, that looks like ordinary leggings and still feels supportive. Our circular-knit CORETECH® leggings are often used as an everyday option, including between or alongside prescribed garments. For a deeper look at fabric and fit, read what to look for in compression leggings for lipedema and our lipoedema compression garments guide. For waist-high abdominal coverage, see compression leggings for POTS.

Frequently asked questions

What sizes do Supacore plus size compression leggings come in?

Many of our women's CORETECH®, POTS and lipedema compression leggings are offered from XS to XXXL. On the official women's CORETECH® leggings size guide, XXXL covers the top of the chart, around 110 to 125 kg (about 243 to 276 lb), depending on your height. Some other styles, including some shorts and pregnancy leggings, currently go to XXL. Always check the size options on the product page and the sizing guides.

Are plus size compression leggings sized like ordinary clothing?

No. As our compression is medical grade, regular clothing sizes do not match CORETECH® sizing. The published size guides use height and weight. Measure yourself and plot both on the chart for the style you are buying.

What if I am between sizes?

If you are between sizes, choose the smaller size. CORETECH® garments are made to feel firm and secure. They should be a neat, tight fit, but they should not inhibit circulation. If the size is wrong, we offer free size exchanges.

Can I wear these leggings for lipedema or POTS?

Many customers wear our waist-high compression leggings for everyday support with lipedema (also spelled lipoedema) or POTS. The main lipedema and POTS styles deliver graduated compression of 25+ mmHg, as stated on the product page. This is general information, not medical advice, so please check with your clinician about what is right for you.
