Compression sizing works differently from regular clothing sizing. There is no universal small, medium, or large. Each garment is sized to specific ankle and calf measurements, and those ranges vary by brand, series, and style. This page explains how to read a size chart and choose the right combination of size, length, and width once you have your measurements.

If you have not measured yet, start there. Our measuring guide covers the five measurements you need and how to take them accurately.

Why sizing is measurement-based

Graduated compression is calibrated from the ankle upward, so the garment has to match the shape of your leg to deliver the pressure it was designed for. A stocking that is too large loses that calibration and does little; one that is too small becomes uncomfortable enough that most people stop wearing it. Your shoe size and dress size tell us nothing useful here. The circumference of your ankle and calf tell us everything.

Reading a size chart

Every product page on this site has its own size chart, because a size III in one series is not necessarily a size III in another. Each chart lists size options against ankle circumference and calf circumference ranges, and for thigh highs and pantyhose it adds thigh circumference.

Find the row where your ankle measurement falls, then check that your calf measurement falls in the same row. If both land in the same size, that is your size. If they land in different sizes, the ankle measurement takes priority, because that is where compression is calibrated and where fit matters most.

Measurements that sit right at the boundary between two sizes are worth a second opinion from a certified fitter or your prescribing clinician before you order.

Length

Length is separate from size, and getting it wrong is the most common fitting mistake. A knee high that is too long bunches behind the knee, which is uncomfortable and interferes with the compression gradient. Too short and it sits below where it should.

• Standard - fits the majority of wearers.
• Petite - for shorter below-knee measurements, so the band sits correctly below the knee instead of behind it.
• Extended - available on some series for longer leg measurements.

Width

Some series offer wide-calf options for wearers whose calf measurement falls outside the standard range for their ankle size. If your calf measurement sits above the range shown for your ankle size, look for a wide option in that series rather than sizing up overall, which would loosen the ankle where you need the compression most.

Styles and where they end

• Knee highs - end just below the knee. The most commonly worn style, since most venous symptoms occur below the knee.
• Thigh highs - extend over the thigh, held by a silicone or knit top band. Used when swelling or vein involvement continues above the knee.
• Pantyhose - waist-high, with even coverage and no thigh band. Also available in maternity styles with a panel that accommodates a growing belly.
• Leggings and crew socks - everyday styles that deliver compression in a form that looks like regular legwear.

Open toe or closed toe

Closed toe is the default and suits most wearers. Open toe leaves the toes exposed, which some people prefer in warm weather, with sandals, or if the toe box of a closed-toe stocking feels tight. Open toe also makes application easier when used with a donning aid. Compression is identical either way, so this is a comfort and preference choice.

If you are between sizes or unsure

Contact us with your measurements and we will help you match them to the right chart. If you have been prescribed compression, your clinician or a certified fitter should confirm level, style, and size. A garment that fits is one you will wear, and consistent wear is what makes compression work.
