UNDER ARMOUR
SIZE CHARTS

Many people are hesitant to order online because of fit. Will it be too tight? Too loose? Too short? Or too long? Will it be the right cut for my body type? Is it supposed to fit like this? To help ease the uncertainty, we've put together a comprehensive fit guide. It will walk you through the various steps to finding the right UA fit for all our gear.



Under Armour® performance gear was built to be consistent with traditional sizing parameters. This means if you normally wear a "Large" T-shirt, you would also wear a "Large" UA T-shirt. So please order accordingly...and with confidence.

BUST: First, find your bust size by measuring around the fullest part of the chest while wearing a bra with little to no extra padding. If you don't have a tape measure, use a string and measure it against a ruler. Find your measurement on the size chart to determine your ideal UA sports bra size.

SIZE CHART

HOW TO MEASURE:
BAND SIZE:Standing straight up with an unpadded bra on, measure closely around the chest just under your arms, right above the bust. If your result is a fraction, round to the nearest whole number. (ex. 33.7" rounded to the nearest whole number, your band size is 34")
BUST SIZE: While wearing an unpadded bra, loosely measure around the fullest part of your bust. Round to the nearest whole number. (ex. 34.5” rounded up to the nearest whole number, your bust size is 35”)
CUP SIZE: Subtract your final Band Size from your final Bust Size to find your Cup Size. (1” difference = A Cup, 2” B Cup, 3” C Cup, 4” D Cup, 5” DD Cup)
DIFFERENCE 1 inch 2 inches 3 inches 4 inches 5 inches

FOOT:We start with the true foot, which means we measure from heel to toe. That measurement (in centimeters) is then translated into our standard sizes.

To find your foot measurement closely trace your entire foot onto a piece of paper and measure from heel to toe. If your measurement is between chart numbers, we recommend sizing up.

FOOT: We start with the true foot, which means we measure from heel to toe. That measurement (in centimeters) is then translated into our standard sizes.

To find your foot measurement at home, closely trace your entire foot onto a piece of paper and measure from heel to toe. If your measurement is between chart numbers, we recommend sizing up. Be sure you're putting your full weight on your foot while tracing. Please note: for the best results, measuring later in the day is recommended.

We created this easy-to-use sizing chart so that finding the right size shoes for your kids won’t be a workout in itself. *Due to the metric/imperial conversions, there will be some instances where two US sizes will equal one UK size or one CM size.
