Under Armour Size Chart

HEADS UP! PLEASE READ ABOUT SIZING & FIT UPDATES.
In an effort to continue to provide the best-fitting product to all athletes, Under Amour has re-evaluated and re-sized their youth apparel. Starting with our Fall/Winter 2018 line (launches July 1, 2018), the youth sizing will better align with industry standards and reflect a new numeric/age as shown here.
How To Measure
CHEST: Place the tape measure under your arms at the fullest part of your chest, wrap around your body until your fingers meet and mark the measurement.
WAIST: Measure around your natural waistline-right above your hips. Be careful not to squeeze too tight to allow a little give.
HIPS: With your feet together, measure around the fullest part of your hips to ensure you'll have enough room to move comfortably.
Fitted: Sits close to the skin for a streamlined fit without the squeeze of compression.
Loose: Full, loose fit for enhanced range of motion & breathable comfort no matter where your workout takes you.

Essential Tools
If you do a lot of online apparel shopping, accurate body measurement using a tape measure is a must. The actual tape you choose doesn’t matter that much.

They are small and light pocket-size measuring tapes, and they have accurate, large and clear markings in both inches and centimeters, which are very easy and convenient to read. They are also great for body measurement, sewing, tailoring, weight loss tracking, or measuring any curved surface.
How to measure without a ruler or tape measure?
If you don't have a ruler or tape measure handy, you can try to measure with a standard credit card, which has a width of 3 ⅜ inch or 8.56 cm and a height of 2 ⅛ inch or 5.4 cm.
