Maternity Compression Leggings: A Pregnancy Guide to Support and Fit
Pregnancy asks a lot of your legs. More blood is moving through them, the growing uterus presses on the veins that carry it back up, and by the third trimester many people find their ankles swollen by evening and their legs heavy after a normal day. Maternity compression leggings are one of the practical tools for that stretch of months. This guide explains what they change compared with ordinary compression leggings, how to fit them as your bump grows, how to build a daily routine around them, and which symptoms should send you to your midwife rather than to a size chart.
Why legs swell in pregnancy
Some swelling in pregnancy is normal. The NHS describes it as common in the legs, ankles, feet and fingers, often worse at the end of the day and further into the pregnancy, and notes that swelling which comes on gradually is not usually harmful to you or your baby even though it is uncomfortable (NHS, swollen ankles, feet and fingers in pregnancy). The same page recommends avoiding long periods of standing, resting with your feet up when you can, regular walks and simple foot exercises to keep the blood moving.
Varicose veins can also appear or get worse during pregnancy. The NHS says that if you get varicose veins while pregnant you may be able to use compression stockings, while procedures or surgery to treat them are not usually recommended until after the birth (NHS, varicose veins). Graduated compression, firmest at the ankle and easing up the leg, is the tool most often used to manage those symptoms: a peer-reviewed overview in the Canadian Medical Association Journal describes graduated compression stockings as a mainstay of managing chronic venous conditions (Lim and Davies, CMAJ 2014). If the pressure numbers on a label are new to you, our guide to what 20-30 mmHg actually means explains them in plain terms.
What maternity leggings change, and what stays the same
Maternity compression leggings have a waistband designed to accommodate a growing bump. Designs differ between products, so check the listed coverage, pressure range and size chart rather than assuming a maternity pair is otherwise identical to a standard pair. The store's A718 is a footless underdress legging with a high waistband.
Three details matter more in pregnancy than they do otherwise:
- The waistband needs room for the bump. Check that it sits comfortably without digging in, and ask your maternity team or a trained fitter if you are unsure about the fit.
- Footless, worn under clothes. The store's maternity leggings are footless and made to be worn beneath skirts, dresses and tunics, so your own socks and shoes stay in the picture and swollen feet are not squeezed by a stocking foot. Our footless and underdress leggings guide covers the trade-offs of leaving the foot uncovered.
- The pressure level is a clinical choice. The store's maternity leggings are made at 20-30 mmHg. Whether that level suits you is a question for your midwife or doctor, not something a long day on your feet decides.
Maternity leggings vs other formats
Leggings are not the only option in pregnancy, and for some people they are not the best one. The four formats most people compare:
One garment for the whole leg with a stretch top that grows with you. Footless, worn under clothes.
The same leg coverage with a firm waistband that sits across the middle. A standard waistband may become uncomfortable as the bump grows; ask about a maternity fit if that happens.
Nothing at the waist at all, which some people prefer late in pregnancy. Held up by a top band; the foot is covered.
The simplest format when the swelling and heaviness stay in the calves and ankles. Easy to put on, nothing above the knee.
Which one fits you depends on where the symptoms sit, what you wear and what your care team recommends. Thigh-highs and knee-highs cover the foot, so they suit people whose feet swell too. Leggings and maternity leggings leave it free. If your days are spent standing, our guide to compression for standing all day goes through shift routines and which format suits which job.
Fit as the bump grows
Compression only delivers its printed pressure when the size is right, and in pregnancy the right size moves. Measure in the morning before swelling builds, following the measuring points on the exact product's size chart, and match those numbers to the chart rather than to your pre-pregnancy clothing size. The store's maternity leggings run from Small through 2XL. If your measurements fall across two columns, follow the chart's fit notes rather than guessing, and ask a trained fitter if you are unsure where to place the tape. Do not change the pressure level to compensate for fit.
Re-measure as the pregnancy goes on. Leg and hip measurements can change between trimesters, and a pair that fitted well at twenty weeks may be tight at thirty-five. Warning signs of a wrong size are numbness, tingling, cold toes and deep marks that do not fade after a rest with your feet up. If any of those appear, take the leggings off, recheck your measurements and ask your midwife or a fitter before buying the next pair. Our plus size compression leggings fit guide walks through the measuring points and what to do when the numbers land across two sizes.
A daily routine for pregnancy
The garment does its job while it is on; the routine around it decides how your legs feel by evening.
- Put them on in the morning. MedlinePlus advises putting compression stockings on first thing in the morning, when the legs have the least swelling, and following your provider's instructions for how long to wear them each day (MedlinePlus). Sit down, gather the leg down to the ankle band, step in and unroll upward, smoothing rather than pulling. Rubber kitchen gloves give a better grip than bare hands.
- Feet up when you can. The NHS recommends resting with your feet up as much as you can during pregnancy (NHS). Ten minutes on the sofa with your feet raised at lunchtime counts.
- Keep the calf pump working. Regular walks and foot exercises, sitting or standing, keep blood moving through the lower legs. The NHS suggests bending and stretching each foot up and down 30 times, then rotating each foot 8 times in each direction. Follow your maternity team's advice about activity.
- Take them off at bedtime unless told otherwise. The NHS describes daytime wear with removal at bedtime for compression stockings in varicose veins (NHS). Follow the duration your midwife or doctor recommends.
- Wash after each wear and air dry. Heat breaks down the elastic. Two pairs in rotation last longer than one pair worn daily.
When to call your midwife first
Some symptoms are not a compression question at all. The NHS lists a sudden increase in swelling in your face, hands or feet as a possible sign of pre-eclampsia and says to call your midwife, GP or labour ward immediately if it happens (NHS). New swelling in one leg, especially with pain, warmth or a hard, painful vein, needs urgent medical advice before any garment. If leg pain or swelling comes with chest pain or shortness of breath, seek emergency help.
After the birth
Legs do not return to normal on the day the baby arrives, and some people are advised to keep wearing compression for a period afterwards. That advice depends on your delivery, your risk factors and how your legs recover, so ask your care team rather than deciding on your own. If your care team recommends continued compression, ask which format and pressure to use after birth. If they recommend standard leggings, the A717 underdress leggings have a conventional waistband; remeasure before choosing a size, because your measurements may have changed.

FAQ
Can I wear compression leggings while pregnant?
Many people do, and the NHS notes that compression stockings may be an option for varicose veins in pregnancy. Ask your midwife or doctor first, especially about the pressure level, and treat any sudden increase in swelling as a reason to call rather than a reason to buy a firmer pair.
What makes maternity compression leggings different from normal ones?
The main difference is the waistband, which is designed to accommodate a growing bump. Check each product's pressure range, coverage and size chart rather than assuming every maternity and standard pair is otherwise identical. The store's A718 is footless and made to be worn under clothes.
Which size should I buy as my bump grows?
Size from your current measurements, taken in the morning at the points on the product's size chart, not from your pre-pregnancy clothing size. Re-measure as your body changes or the fit changes, following the product chart and your care team's advice; a pair that fitted at twenty weeks may not fit at thirty-five. Never change the pressure level to compensate for fit.
How many hours a day should I wear them?
Follow the duration your midwife or doctor recommends. MedlinePlus advises putting compression on first thing in the morning, and the NHS describes daytime wear with removal at bedtime for compression stockings in varicose veins. Take them off and recheck the size if you notice numbness, tingling or cold toes.
My swelling got worse suddenly. Should I go up a compression level?
No. The NHS lists a sudden increase in swelling in your face, hands or feet as a possible sign of pre-eclampsia and says to call your midwife, GP or labour ward immediately. New swelling in one leg, especially with pain or warmth, needs urgent medical advice. Neither is a garment decision.
